THE DIVIDING HEAD. Hardinge and Elgin cataract lathes have a built-in dividing head. In this example I will mate a cylinder with an end cap. I would not want to machine this out of a solid piece of round stock. In the 1st photo I am facing off the end of the cylinder, having already turned the outside perimeter. By using a high speed steel bit custom cut for such work I am able to face the end almost all the way to the live center. The height adjustable Hardinge D9 toolholder is othentimes my choice for use with HSS bits. This bit's cutting tip is well below the top of the bit body, so I am using a spacer underneath the D9 toolholder + the built-in height adjustment (for fine tuning) to bring it up to proper cutting height. A comparison photo of the HSS cutting tip and the most pointed carbide tip I own shows why I chose the HSS bit; I was able to cut much closer to the live center. After facing off the end of the cylinder, I installed a custom modified Hardinge steady rest with needle bearing work supports and proceeded to chamfer the inside of the cylinder. This operation took only a few seconds.....resulting in virtually no scoring of the perimeter of the cylinder. I will be marrying the cylinder with the end cap using 6 small screws, so I next indicated the location of the holes in the cylinder and the end cap. I machined a 45 degree end on a 5/8" bolt that I am using as an indicator punch mounted in a Hardinge L23 boring bar toolholder which is mounted on a Hardinge L18 toolblock. I used the 5/8" bolt because it has the right amount of clearance in the hole in the L23 toolholder + the bolt has a large head for hitting with a small ball peen hammer. With the cylinder and the end cap indicated with punch marks, the holes may be accurately drilled on a drill press. Both of my available Elgin lathes listed below have 60 position dividing heads. The sold Hardinge/Elgin lathe with the enclosed head illustrated below did not have the 60 position dividing head. Most newer Hardinge and Elgin lathes do not have the 60 position dividing head. They do have 4 spindle locks that could be used for that purpose, but 4 stops is very limiting. The last image is of the completed workpiece with a plastic face added to protect the cameras that will be mounted to it.
BECOME KNOWLEDGEABLE. I will help with that. My web pages are not just about selling equipment. They are full of information that you can use. Just by reading this paragraph, you will be able to avoid costly mistakes. This information is not in catalogs. It is not even known by most lathe owners. Most sellers are not likely to tell you even if they know, but most of them are just clueless. Hardinge split bed or cataract lathes maintained the same basic standards throughout their production. Elgin lathes are Hardinge lathe copies, but not all Elgin lathes maintain the same standards as Hardinge. Not all Elgin lathes maintain the same basic standards throughout their production. Before Hardinge bought out Elgin, some Elgin basic standards were a little bit different than Hardinge. After Hardinge bought out Elgin, Elgin basic standards became the same as Hardinge--which meant, of course, that now Elgin lathes had 2 basic standards. The basic standard difference that makes a huge difference is the spindle centerline. The height of the centerline is the same in all vintages of Elgin and Hardinge lathes--4.5" above the bed in the case of 9" swing lathes. Elgin lathes made before Hardinge bought out Elgin were, however, slightly different (offset slightly to one side) so that Hardinge/Elgin headstocks and tailstocks did not line up with one another. Another difference is in the spacing of the holes that hold the accessory trays on the lathes. Early Elgin holes were about 1/16" different than on Hardinge lathes. You will notice that my tailstocks and my accessory trays are labeled as Elgin or Hardinge. I tell you that these items are for one lathe and not the other. I want satisfied customers. I do not want you to buy a piece of equipment from me and find that it does not work for you. I also do not want you to buy a piece of equipment from anywhere and find that it does not work for you. Life to too short, time is too precious, to be wasting it buying something you cannot use and having to return it or resell it. What is even worse is using it for a while and getting inferior results before you figure out what the problem is. One way to avoid such mistakes is to buy a lathe that is altogether and all original as it came from the factory. Another way is to buy from a knowledgeable and honest seller.
HARDINGE CATALOG. This is the only complete Hardinge catalog I have ever had my hands on. The only other Hardinge catalog I have ever had my hands on was dogeared, soiled, torn, with missing pages, etc. The owner of that one allowed me to look at it, but he would not let it out of his house for photocopying. I will not be photocopying this one either because it would be necessary to flatten the pages to do that and that would add significant wear to the catalog. What I am offering is a complete, original catalog in great condition. Someone wrote on the front cover, "Samual Paulson, 29." 116 pages. No copyright date. Catalog is about 100 years old. $300.
THE ELGIN TOOL WORKS STORY: I am frequently asked about the history of the Elgin Tool Works and their relationship with Hardinge. Elgin Tool Works was initially an independent manufacturer in Elgin, IL. Early Elgin lathes used a split bed with the same specifications as the split bed that Hardinge used, and many other parts were similar, but there were significant differences. Most notably, the collets used were different. About the time that Hardinge decided to move operations to Elmira, NY, a group of disgruntled Hardinge employees who did not want to relocate their families bought out the right to use the name Elgin Tool Works and began to manufacture Elgin lathes that were copies of Hardinge lathes with operations moved not just to Chicago, but in the same neighborhood as the Hardinge factory. By this time most Hardinge patents had expired. In most any corporation you will have disgruntled employees; this is par for the course. This renegade group of former Hardinge employees made machinery that was every bit as good as Hardinge; in many cases Elgin machinery is beefier than Hardinge just because, I am guessing, they wanted to save design time rather than steel and weight. The nameplate on the lathe below reads, "Elgin Tool Works, 1770 Berteau Ave. at Ravenswood Ave., Chicago, IL." That was done to show that the Elgin Tool Works was just across the street from the Hardinge Manufacturing Company at the intersection of Ravenswood and Berteau Avenues. Elgin Tool Works was capitalizing on the success of the Hardinge Manufacturing Company. The Hardinge Brothers were not stupid; it wasn't long before Hardinge bought out Elgin Tool Works. For awhile some lathes were made and labeled as was one of the below listed lathes, "Hardinge, Elgin, manufactured by Hardinge Manufacturing Company, Elgin Tool Works Division, Ravenswood, Chicago, USA."
THE ELGIN TOOL WORKS BUILDING at 1770 Berteau at Ravenswood. Photograph made 12/1/2017. The building exterior is probably little changed since the days of the Elgin Tool Works. Hardinge production facilities were also located, in part, in this building, although the nominal headquarters were listed as 4149 N. Ravenswood. I will photograph that building one day.
Hardinge Elgin 5c lathe. If you have ever wondered exactly what the relationship between Hardinge and Elgin was, look at the nameplate that was on this lathe. I removed the nameplate and the forward/reverse and low/high plates from this lathe in order to do a proper job of painting it. The old paint on the lathe was removed, bad defects in the castings were filled, Sherwin Williams primer and industrial enamel were applied--but not everywhere--no paint was put where paint does not belong. I won't put the nameplates back on perhaps until I sell it. I do use the lathe. It would be difficult to keep the nameplates in the condition they are in on the lathe. The lathe is on an original bench of the best design that I have seen. The bench end legs are one piece cast steel tied together with a couple of steel T-bars in the rear and with the 2.125" thick maple butcher block top and lower shelf. The butcher block top is held together with through bolts across the width and glued. There is a steel drawer and a wood shelf to hold 56 collets. This lathe has been sold. Note that this lathe does not have the 60 position dividing head. The 2 available Elgin lathes listed below do have the dividing heads. The open conehead lathes almost all have the 60 position dividing heads.........a distinct advantage.
ALL ORIGINAL VINTAGE ELGIN LATHE. This vintage Elgin literature illustrates an Elgin 5c lathe. I am offering that very model lathe for sale. Any differences are due to a slight difference in vintage. My lathe is completely original. The bed is labeled Elgin. The headstock has model CB5C and serial number 7274 engraved on it. The motor mount is labeled Elgin. The paint job is consistent on the various pieces. Note the 60 position dividing head, the 4 lock stop positions, the dual T-slot compound, the #2 Morse taper tailstock. This is a 9" swing lathe with a 32" bed length. It is in extremely clean condition with very little wear for such an old lathe. I have owned it for about 20-30 years. I bought it from the owner of a technical training school that was in operation during WW2. It was his personal lathe. It was the only lathe left in the cavernous building that housed the technical training school. He had bought it new and was selling it because he was quite old and was already retired for many years and was giving up the building--having already given up the technical training school long before. The patina on the lathe is from decades of use. No attempt has been made to refurbish the finish. There is wear and oil and dirt.....nothing more. The lathe has had only 2 respectful owners. Take a look at the compound. You will find few compounds of half that vintage that look that good. The compound has been cleaned, lubed and adjusted. Look at the bed; few lathes this old have a bed that shows such little wear. I want the lathe to go to a new respectful owner. Many lathes of this vintage are coming onto the market today......but you are unlikely to find any that are this clean, this original and this functional. The original table is included. There are 2 steel drawers underneath the tabletop. There is a shelf about 8 inches off the floor. This lathe has preloaded ball bearing races on the headstock. The motor is a quality ball bearing motor. The lathe is operated with a convenient foot switch. I have many accessories available for the lathe at additional cost. When you see it you will see some accessories mounted on the lathe because the lathe is still in operation on an occasional basis. Many other accessories are near by.....ready to be mounted on the lathe as needed. $2000.
The paint job on the above lathe is original. Elgin painted it in their usual grey and then painted over it in olive drab for sale to the government. During WW2 you could not buy a new automobile or many other things made of steel, which was needed in the war effort. The technical training school was allowed to buy lathes because they were involved in the war effort. It was a perfect paint job. Close inspection of the plate on the bed shows every indication that olive drab is the original color. That Elgin plate is installed with drive screws. The plate could not be removed without damage and it would be impossible to paint around it without it being obvious.
ANOTHER ALL ORIGINAL VINTAGE ELGIN LATHE. Newly painted legs. The turnbuckles and threaded rods were rethreaded before being put back together. Paint was not put on threads. Tabletop newly refinished......without losing the original patina. I stripped the old finish off the tabletop and the shelf, boiled out the embedded oil, then scraped both before applying a fresh clear coat finish composed of many coats. The tailstock is newly cleaned, relubricated, adjusted and properly painted. The headstock and bed were left alone. Theads were refreshed on the motor mount. A new V-belt was installed. Reversing switch conveniently mounted under tabletop under headstock. Quick collet closer. This lathe has preloaded ball bearing races on the headstock and a ball bearing countershaft. The lever action tailstock and the turret tailstock are available in lieu of or in addition to the #1 Morse taper tail stock illustrated with the lathe at additional cost. Accessory drawer under tabletop. Collet rack under drawer. Substantial wood storage shelf under tabletop. The tabletop itself is over 2" thick. Cast iron legs. Appropriate vintage newly cleaned, lubed and adjusted compound. $3000.
Hardinge DSAR compound and crossslide. This is the 2nd latest compound made for split bed lathes. The yoke clamping system is much improved over the T-bolt. It was recently cleaned, lubed and adjusted. This is a big deal. There is a lot of work in CLAing a compound.....and you have to know how to do it in order to avoid damaging the compound. Having had it apart, I can vouch for the integrity of all parts. Having used it for years now I can assure you it is in good working order. Without yoke, $1000. With yoke, $1200.
Hardinge tailstock for Hardinge, not Elgin, 9" swing cataract split bed lathe. #2 Morse taper. Smooth operation. Functions well. Chucks, shanks, etc. found on my TOOLS web page. I disassembled, stripped, prepped, primed and painted this with the original paint color. There is no paint where paint does not belong. All old grease and dirt cleaned out and relubricated. Morse taper hole in good condition; grips shanks properly. $OLD
Elgin tailstock for Elgin, not Hardinge, 9" swing cataract split bed lathe. #1 Morse taper. Smooth operation. Functions well. Chucks, shanks, etc. found on my TOOLS web page. I disassembled, stripped, prepped, primed and painted this with the original paint color. There is no paint where paint does not belong. All old grease and dirt cleaned out and relubricated. Morse taper hole in good condition; grips shanks properly. $400
Elgin lever action tailstock, for Elgin, not Hardinge, 9" swing cataract split bed lathe. Very fast, convenient and sensitive operation. For 9" swing cataract split bed lathe. #2 Morse taper. Complete. Functions well. For these photos, I leveraged the spindle about an inch forward and clamped the spring loaded spindle in place in order to show the device's operating position better. Chucks, shanks, etc. found on my TOOLS web page. I've been working with this tailstock since I got it; I like it! I disassembled, stripped, prepped, primed and painted this with the original paint color. There is no paint where paint does not belong. All old grease and dirt cleaned out and relubricated. Threads had a tap run through them or a die run over them. The spring pulls the spindle away from the work when the operator lets up on the lever. Note the adjustable threaded stop under the spindle at the tail end. I have quit using it now that I have refurbished it. It's too attractive to use. I do not know how long that will last. Morse taper hole in good condition; grips shanks properly. RARE. $750
ELGIN TURRET FOR ELGIN, NOT HARDINGE, 9" SWING SPLIT BED LATHES. Talk about fast! You can do production work with this. You can compete with CNC machinery without spending a fortune and leaning a new vocabulary. Accepts 5/8" diameter tooling. Complete. Functions well. The handwheel is custom, is very well concieved and executed and is a great feature. The shafts ride in brass bushings. Boston steel gears. The lever of the original design can get in the way. I have added a photo of an Elgin turret as originally designed. Accepts 6 different tools, each with an adjustable stop. You may work with any one tool repeatedly, or rack the wheel all the way to the right and the turret changes to the next position. So you may perform up to 6 operations on the same part without changing parts or tooling or setup. The turret is rare, but this turret is UNIQUE. $800
Lathe bench with drawers. The lathe itself has been sold. It was uneconomical to ship the bench. It would take very little time to mount a Cataract bench lathe on this bench because short bed and long bed Cataract bench lathes have already been mounted on it. I plugged the holes, but the plugs would be easy to remove. It could serve for virtually any benchtop lathe, or for that matter for just about anything else. It is a fairly ordinary commercial workbench. The metal drawer on the left is about 20X20" inside dimensions, with a sliding tray inside. The wood drawer on the right is about 18X26" inside dimensions and is presently set up to receive Hardinge 4c collets in front and miscellany in the rear. The bench top is 28" deep, 60" long, with metal fence around 3 sides. It is 34" high. There is a full length underneath shelf about 9" off the floor. The legs are metal. The top is about 2" thick maple. $300 picked up as illustrated with both drawers. The wood drawer is one I custom built. I utilized very long and high weight capacity ball bearing slides that cost me over $100. If you leave the drawer with me, the price is $200.
Hardinge slide out 5C collet rack from DSM59 lathe. Slides on ball bearing rollers. Newly cleaned and lubed (after photo was made). Holds 32 5C collets. When I get around to adding wood sides and attaching it to the underside of one of my bench lathes, the price will go up. $150.
Taper spindle toolholders and diamond laps. 20 pieces total. The 2 on the far right hold 1/8" and 3/32" shafts. The 2 next to them stabilize flat disks. The one with a grinding wheel on it has a screw in the end. Most of the others are diamond laps. The shafts taper from about .200" to .150" over a 1" length. $300 for the lot. These probably fit Hardinge or Elgin compound mounted grinders designed to be driven from an overhead round belt drive. I see those grinders sell from time to time.......always without such tooling, which renders those grinders useless.
Hardinge Live Center, #2 Morse taper. Labeled "Hardinge Bros., Elmira, NY." Well used. Tested; performs well. $OLD
Hardinge Center or Steady Rest for 9" swing split bed lathe. All original. Complete. Fits Hardinge or Elgin Cataract beds. Center rests are often found in much lesser condition. This is about as clean as you are likely to find. Although this one has been sold, I do have another one in stock that I will photograph and add to this page soon.
Hardinge Center or Steady Rest for 9" swing Hardinge or Elgin Cataract lathes. Note that the 3 support bars are double ended. One end is hardened steel. The other end is also hardened steel, but I installed roller bearings on it. Roller bearings take up less room than ball bearings allowing you to cut larger diameter material. Bearing supports are necessary for supporting soft materials without digging into the stock. The roller bearings work on hard material too. The lathe is in motion while I cut off the end of the plastic tube. I am not selling this. I just wanted to show it to you in case you want to do the same. I can supply 9 roller bearings for $30. The roller bearings are mounted upon shoulder screws.
You need to be aware of reality concerning Hardinge lathe compounds. A new DSC Hardinge compound and crossslide would cost you $6500.....except that they are no longer available new. A rebuilder charges $5800 for rebuilding a DSC. Of course, virtually no one has their DSC compound rebuilt at that price. Older compounds for the split bed lathe and parts for them are not available new, so it is virtually impossible to rebuild them. Scarcity makes the older compounds in good condition even more valuable than more modern compounds. Compounds are an integral part of your lathe. Your lathe is worth little without a good compound. Take care of the compound you have. Be willing to pay a fair price for a good used compound.
How I package your compound for shipment. Shippers charge for dimensional weight, so it is necessary to package like this to save on shipping cost. I remove the handles and build a rigid insulation cradle for the compound. I fill up the box with rigid foam; the finished package is a solid brick of foam. You can expect anything I ship to you to be packaged well. It is necessary to package things well and insure them. Insurers do not pay for negligently packaged items. Packages must be insured to protect against lost packages or mishandled packages. You and I are both protected!
Hardinge DSC compound and crossslide. Tight tolerances on this little used compound. Tapered gibs on the dovetail slides and double nuts on the screws take up any play. None of the usual damage on the dovetails. This fits 3 3/8" wide dovetail lathe beds. Newly cleaned, lubed and adjusted. This is a big deal. There is a lot of work in CLAing a compound.....and you have to know how to do it in order to avoid damaging the compound. $1800
Hardinge DSC crossslide/compound longitudinal feed screw. This has very little wear on the screw, but the shaft is bent. It is possible to straighten the screw. This was damaged in transit to me. A high percentage of compounds shipped to me are damaged in transit because people do not know how to package the compounds. No compound I have shipped has been damaged in transit; see above for how to package compounds. $75
Hardinge/Elgin cataract crossslide/compound T-bar. On the older split bed lathes it is the T-bar that aligns the compound with the bed. It is made of properly hardened steel. It fits very precisely. You cannot have any play in the T-bar/compound interface. It also plays a role in locking down the compound to the bed. Without it, the compound will be easily moved out of alignment by the cutting process. $200
Hardinge cataract crossslide/compound base. The Dovetail included angle is 45 degrees. 3.5" wide. 6.5" long. T-bar is 6" long. It could be worth it to you just for the T-bar. The whole assembly could be the base for a custom tool for your split bed lathe. $150.
ELGIN LATHE MILLING ATTACHMENT. Newly cleaned, lubed and adjusted. Designed to be mounted on your lathe compound or upon a rotating lever action tool holder which in turn would be mounted upon a double cross slide. 3 photos show the Elgin milling adapter mounted on a an Elgin 9" compound and lathe. One photo shows the milling spindle at its lowest position of about 1/2" below the lathe centerline. Another photo shows the milling spindle at at its highest position of about about 1 and 3/8" above the lathe centerline. One photo shows the Elgin milling adapter with a drive belt installed. One photo shows the milling adapter mounted on a Hardinge Model D straight and taper slide, which is mounted upon an Elgin Double Cross Slide; this works at least as well as mounting the milling adapter upon a Compound and cross slide. Only the milling adapter itself is what is being sold. The lathe, the compound, the double cross slide, the straight and taper slide, the T-nuts, the bolts, the washers, and the belts are not included. Read the page from the Elgin catalog for more detailed info. Look at this milling attachment that sold on Ebay for $499 + shipping (item #142731486080). $400.
BELT FOR LATHE MILLING ATTACHMENT OR GRINDER. 110" long. .144" diameter. New-old-stock. $50.
ELGIN DOUBLE CROSS SLIDE for 9" swing lathe. Rack and pinion transverse movement, with adjustable stops to control extent of movement. Shown on a Hardinge/Elgin 9" lathe--for which it was designed. This is a direct copy of a Hardinge crossslide. In the last photo you see it being used with a Hardinge Model E rotating lever action tool holder and in 2 other photos you see a tool holder block mounted upon this cross slide; these parts are available as accessories and are listed below. This is for the split bed lathes. A hold down bolt is built into this cross slide. Use your compound hold down nut with that hold down bolt. $700.
DOUBLE CROSS SLIDES are, by design, more accurate in the cross movement than are compounds. Both of these cross slides straddle the lathe bed, eliminating any chance of misalignment. Here the below listed 9" Hardinge cross slide stop was positioned to end the tool travel at the exact center of the workpiece. This workpiece was perfectly faced off. The face of the workpiece is absolutely flat. Have you tested your compound of late? Most compounds will give you a slightly dished or raised center. If you need to face off a part as square and as flat as possible, use a cross slide. There is no play in the longitudinal direction as there is in a compound. There is no feed screw to wear unevenly. Pushing a lever is a lot less work than turning a handscrew. You do not need to adjust it or check it for square. Of course, cross slides are not just for facing off perfectly. In the last image I am using the cross slide to remove a lot of waste quickly. (The alignment is not a simple matter of adjusting the compound; after all, you can face off with the compound at an angle and do just as well as with the compound at 90 degrees. Proper alignment is determined by the T-square on the bottom of the compound. Split bed compounds do not have T-square adjustment and most of them are slightly out of alignment. Have you tested yours? This is something you should do before you use your lathe.) If you want to face off with surety that your workpiece will be faced off flat use a double cross slide.
HARDINGE DOUBLE CROSS SLIDE for 9" swing lathe. Rack and pinion transverse movement, with adjustable stops to control extent of movement. This is for the split bed lathes. Use your lathe T-bolt from your compound to hold this to your lathe bed. Hardinge Model E rotating lever action tool holders and tool holder blocks are designed to be used with this cross slide; these parts are available as accessories and are listed below. See photos immediately above and below of this double cross slide. Although $OLD, the infoirmation and photos relate to all other crosslides.
Hardinge Model D straight and taper slide. Screw in the screws sticking out of either end to limit the travel of the lever action. Newly cleaned, lubed and adjusted. These are used on double cross slides. Hardinge Model D an d E straight and taper slides are the same height. $300.
TOOL HOLDER BLOCK. Designed to work with the above listed Hardinge/Elgin double cross slides. 5/8" wide slot. 1" high. If purchased with a double cross slide, $80. If purchased separately, $120.
TOOL HOLDER BLOCK. Designed to work with the above listed Hardinge/Elgin double cross slides. 3/8" wide slot. 1" high. Works well with the Empire cut off tool holder. Note that the T-bolts are off center and the top plates are custom; the end result allows the cut off blade to be near the edge of the double cross slide. If purchased with a double cross slide, $80. If purchased separately, $120.
TOOL HOLDER BLOCK. Designed to work with the above listed Hardinge/Elgin double cross slides. 3/8" wide slot. 1.3" high. If purchased with a double cross slide, $100. If purchased separately, $150 each. 2 available.
HARDINGE D2 TOOL HOLDER. Works perfectly with the above tool holder block. The D2 is what is designed to work with tool holder blocks and on Hardinge slides on Hardinge cross slides. See it in action with the above listed Hardinge double cross slide. If purchased with a double cross slide, $100. If purchased separately. $OLD.
Hardinge rear T-slot lathe bed. Required for use with the rear thread chasing attachment. With no accessories, no small parts tray. The brass Hardinge logo was removed by a previous owner. Inscribed in the end of the bed, "Hardinge Bros. INC., Chicago, USA, No. 3766." T-slots cleaned out. Threaded holes cleaned out with proper taps. Bed does show use, but no serious damage. Newly cleaned, prepped, primed and painted with the original color. There is no paint where paint does not belong. $350.
It is my intension to replace the bed on my thread cutting lathe with the newly spruced up bed above, but the bed below is quite acceptable to me, so I am willing to sell either bed. There were several reasons for buying the above lathe bed. The bed has the rear T-slot, it came with a parts tray, and the price was attractive. I have been wanting to spruce up my thread cutting lathe. With a 2nd bed, I could spruce up the bed and then make a quick swap. There is still a lot of work involved in swapping out beds, however, and I am pretty busy, so until I do swap out beds, both remain available...but, of course, only one or the other.
Hardinge rear T-slot lathe bed. Required for use with the rear thread chasing attachment. It is the bed seen with the lathe at the top of this page. With no accessories, no small parts tray, no striker plate, no striker plate contact screw. It has been rescraped by a previous owner. Functions well; I have been using it for many years. $200. The striker plate in the below photo has been $OLD, or rather traded for a different Hardinge thread chasing attachment accessory. I welcome such trades. The striker plate contact screw is still available, 1/4-26TPI, hardened to just the right amount, RARE, you could make your own, of course, but not for $75.
Hardinge rear T-slot lathe bed SPACERS. Hardinge made different rear thread chasing attachments. Some were made for beds with a cross section like you see in this image. Some required a rear T-slot that was positioned further back. A set of 3 spacers like the one you see in the below photo, made out of steel castings, machined and ground on the mating surfaces, complete with T-bolts, that go between the rear T-slot and the rear thread chasing attachment, are available for $350. Alternatively, these could be added to a flat-back-sided Elgin lathe bed in order to use it with a rear thread chasing attachment. It would work with other lathes as well.
Hardinge small parts tray. Mounts in front of headstock. See photos of them on my lathes. The mounting holes are 5 9/16" apart. This one came in on the above listed Hardinge lathe bed. Held on with two 1/4" screws. Cast iron. Old paint stripped off. Metal cleaned and prepped. Freshly painted with primer followed by a top coat of original paint color. Perfect condition. $145.
Elgin small parts tray. Mounts in front of headstock. See photos of them on my lathes. The mounting holes are 5 1/2" apart. Held on with two 1/4" screws. Cast iron. Original paint. $100.
Hardinge Taper attachment for thread chasing lathe. You may tilt that hardened striker plate in either direction and cut internal or external tapered threads. This is the only one seen by either the octogenarian Hardinge collector or myself. Before I put it on my web page it was fun to ask visiting Hardinge afficionados what it was. None had ever seen one before or even knew that a taper attachment had ever been made for the Hardinge thread chasing lathe. EXTREMELY RARE, $600.
Hardinge thread chasing attachment component, "banjo." Holds the gears between the spindle gear and the rear T-slot mounted shaft. Original Hardinge cataract lathe part essential for front or rear thread chasing accessories. RARE. The only reason this was not sold long ago is that the thread chasing assemblies themselves are rare. Just as rare are those who know how to complete them and use them. $200.
Hardinge head stock stop pin. Engages holes in the head stock to hold head stock in place for changing chucks, etc. Original Hardinge cataract lathe part, properly hardened and finished. 5/16" diameter. 2.75" overall length. $50.
Rear bar stop for Hardinge thread chasing attachment. Original Hardinge cataract lathe rear thread chasing part. RARE. $100.
60 tooth Hardinge gear. 1.746" ID. 0.355" wide. I do not know how this was used, but it has the right pitch to mate with Hardinge cataract lathe gears. If you needed to, you could slip this over a 50 tooth gear and epoxy it in place to make a 60 tooth gear. $50. If you need a 50 tooth gear for this purpose, add $100.
Adapter for Hardinge thread chasing attachment. I made this to allow me to use a Hardinge thread chasing attachment on a bed that had some holes in the tail end for a different thread chasing attachment, but not located in the proper location for my thread chasing attachment. The 3/8-24TPI screw is a Hardinge screw. The 1/4" dowel pins are spaced 2" on center. The threaded hole is 1/4-28TPI. The top cutout is the width of the T-slot and provided clearance for the T-slot. $50.
Hardinge Morse Taper #2 drill plate. Put it in your tailstock and a drill in the headstock and you have a horizontal drill press. Of course it has other uses as well. Face it with superfine sandpaper and finish the cut off face of a workpiece in the lathe. Stick it in your Clausing mill head and use your mill to press a bearing into place. Use your imagination. Uncommonly found. $OLD
Hardinge lever action collet quick closer part. The gap is ~1.5". The block on the other side is ~0.75". $95
Hardinge lever action collet quick closer part. This fits both my old Hardinge and my old elgin lathes. It is illustrated on my Elgin lathe. Stamped "RO-530" or something close to that. $100

Hardinge lantern style toolholder for Hardinge and Elgin 7" compounds. It is the one on the right sitting next to a 9" version. The bar that goes into the T-slot is 3/16" thick, 7/8" wide. I have no toolbit holders to fit it. $60.
INCOMPLETE Hardinge lantern style toolholders for Hardinge and Elgin 7" compounds. The bar that goes into the T-slot is 3/16" thick, 7/8" wide. I suggest you buy these with the above listed toolholder for spare parts. $30.
SMALLEST Hardinge lantern style toolholder I have. Incomplete, for parts. The lantern post is .625" in diameter. The slot is 3/16" wide. $15.
Tight quarters turning toolholder custom made for Hardinge lathes. Lots of clearance with this toolholder. Accepts 3/8" toolbits and holds them @ 1.095" above the compound. T-bolt and nut not included. $OLD.
TURNING and BORING BAR TOOLHOLDER custom made for Hardinge lathes. What you get is what you see in the 1st 2 pictures. That is a 1/2" diameter shank carbide tipped boring bar in the toolholder; the cutting tip sits 1.095" above the top of the compound. 3/8" carbide tipped toolbits also sit at that same height. T-bolt and nut not included. $OLD.
BORING BAR TOOLHOLDER. Made for use with an Elgin Toolworks 9" lathe compound such as illsustrated on the above ALL ORIGINAL VINTAGE ELGIN LATHE. It was made by the technical training school instructor I bought the lathe from. You will not find another boring bar holder that provides better stability than this one. The toolbit cutting height is about 1.035" above the compound top. The toolholder may be cut down as required by milling the bottom surface of the main toolholder block. Note that the T-slot in your compound must be parallel with the bed. Accepts 1/2" shank boring bars. $100.
CUTOFF TOOLHOLDER. Made for use with an Elgin Toolworks 9" lathe compound such as illustrated on the above ALL ORIGINAL VINTAGE ELGIN LATHE. The toolbit cutting height is about 1.255" above the compound top. The toolholder may be cut down as required by milling the bottom surfaces of the main toolholder block. Accepts 2 different size cutoff bars, one of which is included. $100.
Hardinge, Elmira, NY, USA, D9 toolholder. Height adjustable. Accepts 3/8" toolbits. It pays to have different toolholders. The L18 Hardinge is a great toolholder, but it will not do it all. The D9 has a little more height for the toolbit. I am using the D9 in the last photo to hold a vintage knurling tool that will not fit into any of the L18 toolblocks. $150.
Hardinge, Elmira, NY, USA, D9 toolholder. Height adjustable. Accepts 3/8" toolbits. $125.
Spacers to extend the range of the Hardinge D9 height adjustable toolholder or D9 copies. They are surface ground. They are .200", .165" and .110" thick. They allow you to use smaller tool bits and still be able to bring the bits up to center height or they allow you to use the toolholder on a compound or wherever you may need more height. $50 each
Hardinge, Elmira, NY, USA, L18 quick change toolblock. This is Hardinge' best toolblock. It will work on new or old compounds, although the T-nut may need to be cut down to fit some older compounds. The many different tollholders made to fit the tollholder block are all height adjustable. The toolholders accept boring bars, cutoff blades, 3/8" carbide bits or HSS bits, 3/8" shaft Thinbits, knurling bits, etc. The toolholders may be installed in either of 2 positions and the toolblock may be installed in any number of positions. In the last image of the toolblock mounted on the compound for the purpose of turning a 7.5" diameter circular plate made of plastic, the toolholder is mounted 180 degrees to its usual position in order to position the circular grooving tool (being used to turn the OD) farther away from the spindle than the cross slide would otherwise allow. The toolblock is easy to align with a trisquare, but you may install it at any angle on the compound. Only the toolblock is being offered. I have toolblocks mounted on multiple compounds, but I recently sold a compound so I have an extra toolblock available. It seems like I never have enough of the toolholders because I leave toolbits mounted in the toolholders ready for use. $200.
Hardinge L20a knurling toolholder. This is not for sale. I just wanted to show you how to use it. People seem perplexed by it. In fact, it is easy to understand how to use it. Just use your common sense. First, center the toolhoder with the spindle. Do that with a cylindrical hole punch in the toolholder groove.....aligned with a centering collet. Make sure you have the right knurling wheels installed. You want wheels that are 3/4" in diameter, 1/4" thick, with a 1/4" hole and teeth parallel to the center hole. The wheels must turn freely on the shoulder screws. The shoulder screws need not be ground down like mine are; they came to me like this. Clean and lube all. Adjust the through shafts that the shoulder screws screw into so that the knurling wheels are flush with the piece to be knurled. Lock the shafts in position. Now you are ready to cut the knurl on the workpiece. To be sure it is set up properly lightly cut while hand turning the spindle. Like what you see? Proceed to make a deeper powered cut. The workpiece you see is the first knurl I made with the L20a. All images are to show you the cutting position of the wheels........for, in this case, a 3/8" shaft. Not for sale. This post is strictly for your benefit.
3/8" square trepanning or circular face grooving toolbit. Custom made for face grooving inside a recess. Designed to cut an about 11/16" outside diameter. Even if it is not the perfect size for your needs, it could save you a lot of time. $25
FREEHAND TOOL REST for 7 to 9" lathes. About 4 1/4" long base. Unusual L shape would be good for many things. Of particular note would be as a support for turning the inside of a bowl and rounding a corner. Very sturdy piece. Shank is .735" diameter. $125.
FREEHAND TOOL REST. About 3.25" long. 5/8" shank diameter. No base support. $25.
Hardinge bench center, with 24 position dividing head with 5c collet drawbar, with screwfeed adjustable tailstock, 5 T-nuts. $500. I have 2 of the dividing heads. The cleaner one is illustrated on the bench. In the 2nd photo you see the bottom of the cleaner one on the left. Those round keys are ones I made for use on my Clausing milling machine. They are not included. The original keys looked like those on the bench tailstock on the right. The dividing head in the center is not as clean as the one included with the lathe; it was used on a grinder and the grinder marks are visible. It works fine and if you choose to buy the bench with it instead of the cleaner one, the price of the outfit is $400.
NEED A COLLET RACK? Think outside the box. Draw a centerline down the middle of your rack top, then draw appropriate sized circles as illustrated to place your collets equidistant from each other. Intersecting lines are the centers of the holes to be bored.
AVAILABLE 5C ROUND COLLETS: 1/16, 1/8, 9/64, 5/32, 11/64, 3/16, 7/32,17/64, 9/32, 19/64, 5/16, 13/16, 11/32, 21/64, 23/64, 3/8, 25/64, 13/32, 7/16, 15/32, 1/2, 33/64, 17/32, 35/64, 9/16, 19/32, 39/64, 5/8, 43/64, 23/32, 3/4, 49/64, 25/32, 7/8, 1 1/16, 1 1/32. I willing to trade for these 5c round collets: 1/64, 3/64, 5/64, 7/64, 29/64, 31/64, 27/32, 1 1/64, 1 3/64, 1 5/64, 1 7/64. I am willing to trade for square, hexagonal and unusual collets as well.
1/4" 3C COLLET The Inside diameter at the bottom of the collet is 1/2", which is the maximum diameter of a 3c collet. 26TPI threads. $30.
HARDINGE 5C DRAWBAR. This drawbar is 12" from the shoulder to the end. There is a ball bearing at the shoulder where it contacts the spindle. The handwheel is 3.125" in diameter. $150
DRAWBAR LEVER WRENCH. This hand forged drawbar closer works with 3.125" and 4.125" diameter handwheels. It is a work of art and virtually indestructable. $60
Faceplates do not extend out as far from the spindle nose as do chucks, therefore they run more accurately. Faceplates will hold larger diameter stock and odd shaped stock that will not fit into chucks. It is good to have more than one. I have a special jig mounted on one that I leave in place for convenience.
ALL SOLD OUT
3-jaw chucks are what most people use most of the time, primarily for the convenience. Consequently, used 3-jaw chucks oftentimes have a lot of wear. So beware of used 3-jaw chucks. If you buy a used 3-jaw chuck, disassemble it and inspect for wear, return it if it is too worn. Why did you buy your Hardinge lathe? Wasn't it for the quality? If it is quality work you want to acomplish, consider 4-jaw and 6-jaw chucks. 6-jaw chucks do the best job of holding hexagonal or round stock, especially round tubing; more jaws grip better and distort less. 4-jaw chucks do the next best job of holding round stock, and are needed for holding square stock. If you can only afford one chuck, buy a 4-jaw chuck because you will be able to hold rectangular and round stock. 4-jaw chucks have reversible jaws; one set of jaws serves as inside and outside jaws. If your 3-jaw chuck does not run true, there is no adjustment for that. You can adjust your 4-jaw chuck until it does run true. Already have some chucks? Test them. Do you have both 3-jaw and 4-jaw chucks? Comparison test them. I can guarantee you that your 4-jaw chuck, properly adjusted, will outperform your 3-jaw chuck for holding round stock (given equally good chucks).
Jaws: Chucks have serial numbers on the body and on the jaws; they are supposed to match. Hardinge chucks have numbers on the individual parts too; they are supposed to match. I bought a Hardinge 3-jaw chuck off Ebay where one jaw had a non-matching serial number that screwed up the operation of the chuck. The seller sent me another set of Hardinge inside jaws with matching serial numbers, (they did not match the chuck's serial number, however) that ran quite true on the Hardinge chuck, nevertheless. I already had a set of Hardinge outside jaws that perform well on this Hardinge chuck. It is best that the serial numbers on the jaws match each other, although they need not match the chuck's serial number. It does not matter that all numbers match.......if you determine by testing that all works well together.
BUCK 3-JAW ADJUST-TRU CHUCK WITH PIE JAWS AND 2 3/16" BY 10TPI THREADED BACKPLATE FOR HARDINGE . 3 sets of uncut jaws. 1 set of aluminum pie jaws, + 2 sets of reversible unhardened steel jaws. No key. I bought this for my own use, but I will not be able to use it until I come up with a backing plate for the HLV-H taper spindle nose. So it is for sale presently or I am willing to buy or trade for the appropriate HLV-H taper spindle nose Hardinge back plate for it. Pie jaws are used to hold delicate rings (such as those used in a watch or clock) without distortion. You may bore the aluminum pie jaws to suit your needs. The pie jaws are 1.5" thick. The steel jaws are also 1.5" thick and they too have matching serial numbers. The 1st set of numbers relate to the chuck that the jaws are intended to be used with. The 2nd set of numbers denote the type of jaws. The retaining screws are deeply recessed. You may bore the jaws to a depth of 1.175". There is a 0.86" pilot hole bored in the jaws. Someone has bored a 1.4" diameter hole partially through for their use. The chuck was disassembled when I got it to insure that it was in good condition. The chuck is newly cleaned, lubed and adjusted. Note that the pie jaws have matching serial numbers. $700 as described and illustrated or will swap the threaded back plate for an equally good condition Buck Adjust-Tru Chuck for Hardinge HLV-H taper spindle nose backplate. I have illustrated some distinguishing characteristics and measuirements of a 6" Buck Chuck Adjust-Tru backing plate.
BUCK UNHARDENED STEEL JAWS FOR A 6" 3 JAW CHUCK. 3 sets available. These fit a Buck chuck like the above. $100 per set.
HARDINGE 30AHC 3-JAW CHUCK for parts only. No jaws. No key. No backing plate. Otherwise complete. Well worn, but functional. I removed and machined the backing plate for another use. You can see the backing plate in the 3rd image, but it is not included. Disassembled, cleaned and lubricated. The 3 gears that adjust the scroll are all in good usable condition. $50 for parts only.
SET OF INSIDE JAWS FOR (PROBABLY 5") 3-JAW CHUCK. All with matching serial number 16249. These are not Hardinge jaws; they may fit a Skinner or Union chuck or some other chuck. The jaws are 0.428" wide, 1.519" long and 1.247" high. $50
HARDINGE 36HC 4-JAW CHUCK. Reversible jaws. For Hardinge HLVH 5c taper spindle nose. The serial numbers on the jaws match the serial number on the chuck body. Of course, this chuck runs true on a Hardinge HLVH 5c taper spindle nose. $400
FACTORY MADE CHUCK KEY for HARDINGE 36HC 4-JAW CHUCK. I have only one chuck key for my Hardinge 4-jaw chucks, so it is priced separately from the above listed chuck. $50 with above chuck.
7.5" 6-JAW BUCK CHUCK. Tru-adjust. With inside and outside jaws. The serial numbers on the jaws match the serial number on the chuck body. Note the special feature of the inside jaws that allows you to hold a dime or even a smaller item. With Hardinge 5c taper spindle nose backing plate machined from a Hardinge hardened 9" faceplate; runs true and allows the Buck Chuck Tru-adjust system to work. I use this on a Nikken rotary indexing table with a Hardinge 5c taper spindle nose on a milling machine for accurately locating holes concentrically. Occasionally I use it on a Hardinge lathe with a ball bearing spindle. I have even used it on my old Hardinge sleeve bearing thread cutting lathe.....for cutting much larger diameter threads than that lathe was designed to cut. I have available a 2 1/4 x 8TPI threaded backing plate for this chuck; see Tools web page. Great chuck in great condition. $OLD.
ROTARY TABLE with HARDINGE 5C TAPER SPINDLE NOSE. This is the rotary table I mentioned in the above listing. I had a Hardinge 5c taper spindle nose centerless ground to a "slip fit" to the Nikken rotary table. In the right foreground is a short drawbar I made that allows me to use collets on the rotary table. I may now machine something on the lathe and move the chuck with the workpiece to the rotary table on the milling machine for further machining--usually locating holes concentrically. When you mount a workpiece in a chuck there will be some distortion of the workpiece. When you remove the workpiece from the chuck and then remount it in a different chuck, there will be a different distortion of the workpiece. The job I was working on at the time I came up with this idea would not tolerate any such distortion. It required that a large hole be bored in the workpiece with several small holes located concentrically around the perimeter of the large hole. This was the most efficient solution to that problem and it has served me well for many projects in the many years since. I use it frequently. This is not for sale. It is just an idea that you are welcome to utilize. I do have a surplus-to-my-needs new-old-stock Nikken 12 position quick indexing plate (I am using a 24 position plate) available for the Nikken which I am willing to trade for a Nikken quick indexing plate that will not duplicate my capabilities. I may be willing to buy your Nikken quick indexing plate outright. In the 2nd photo the thru hole was bored with the Nikken spindle axis horizontal, then the rotary table was repositioned and the 4 small holes were bored. By leaving the workpiece in the chuck, those small holes were positioned perfectly using the rotary table. Before removing the workpiece from the chuck I added 2 more holes in the 6 hole pattern in line with the large bored hole--for set screws, in case they are needed. In the 3rd photo you see the completed tripod head mounted on the handlebars of an electric trike that I built. In the 4th photo you see a gimbal head and camera mounted on the piece that I made. I will use it like this for creating video of the trike from the driver's point of view. Then I will use the gimbal head for long lens nature photography--the ultimate intended purpose of this setup.
HARDINGE 5C TAPER SPINDLE. I use the above rotary table a whole lot. It allows for great accuracy with ease. Switching parts between the lathe and the milling machine is so easy and seamless......with no loss of accuracy. For years I had the rotary table on this web page as a service to you. The rotary table was not and is not for sale. It has been and continues to be an information source for you. It is an idea you might want to put to use for yourself. To do that you need a Hardinge spindle. I can now offer you a Hardinge spindle. You could buy a cheap lathe and canibalize it for the spindle and other parts.........but the work of removing the spindle from the headstock is considerable. The difficult work has been done for you with this spindle. $OLD
HARDINGE REVOLVING VISE. 4" wide, 1" high jaws, 2 3/4" maximum opening. Low profile, high quality Hardinge vises are ideal for Clausing, Hardinge and other similar sized mills and for most of what I want to hold in a vise. Keys not included. I have several size keys available--see below. Handle not included. I now have a crank hande available, which I will post soon. $400
HARDINGE VISE KEYS. 5/8" wide, 9/16" wide and 7/16" wide keys available. Each supplied with appropriate 10-32TPI socket head cap screws. I can also supply a set of round 9/16" wide keys with 1/4-20 TPI socket head cap screws. The round keys are a GLENNVIEW product. The rectangular keys came in with Hardinge vises. Your choice, $75 per pair.
BELT TENSIONER FOR FLAT BELT DRIVE HARDINGE OR ELGIN LATHES. This is what is called a swinging idler pulley. You can read about one described in the copy of text from a book under the overhead line shaft drive system listed below. Will work with other lathes as well. Should work with most lathes as is. I left the hardwood arm that holds the wheel long so that it may be repositioned for use on larger lathes. The 1 11/16" wide steel wheel weighs 4# 10 ounces. It runs on 2 needle bearings on a shoulder screw shaft. Take a look at the lathe belt without the belt tensioner in use. I installed that belt myself. It is a new leather belt installed as tightly as I could manage on the fixed position cone head pulleys. Note how much the belt is further tensioned with the belt tensioner in use (the lathe wheels and belt are moving in this photo). Leather belts stretch with use. The idler pulley automatically takes up the slack. The belt tensioner needs to be clamped to the tabletop to keep it in position. This belt tensioner dramatically reduces belt slippage and increases the driving power of flat leather belt driven lathes. I offer it for sale only because I can make another for my own use. The asking price will cover my time and materials. $350.
BELT TENSIONER FOR FLAT BELT DRIVE HARDINGE OR ELGIN LATHES. This is what is called a captured pulley. I was cutting much larger diameter threads on my old Hardinge thread cutting lathe than Hardinge intended. I needed more drive power. The belt was nicely laced and lined with rubber so I did not want to cut it shorter and relace it. Within a few minutes I found some surplus materials laying around that I put to use. I am not offering this for sale. It is specific to my lathe. It is just an idea that you may want to use on your lathe.
10.5" and 9 5/8" DIAMETER FLAT BELT PULLEY. Cast and machined. With integrated 7/8" diameter shaft that extends out from side of pulley 9 3/8". 11 3/4" overall length shaft. 7/8" width crowned pulleys. $125. $175 for both pulleys if purchased with the smaller pulley listed below and illustrated along side this larger pulley for size comparison.
2-STEP CROWNED PULLEY. Cast iron. .703" diameter hole with key and set screw. Diameter of the pulleys are 4.7" and 4.4". Width of each pulley is about 1". Understand that the pulley diameters do not have to exactly match the diameters of the pulleys on your cone head lathe if you mount the driver pulley on an adjustable mount. The width of the pulley does not have to match either; the belt needs to be sized to the smaller width pulley only. These are crowned pulleys; the running belt will find the pulley center. $70.
RUBBER FACE FOR YOUR LEATHER BELT. The leather belt on this lathe is decades old. A new leather belt would not perform any better. Adding a rubber face dramatically increased the driving power of this flat leather belt driven lathe. The leather provides the dimensional strength, the rubber provides the grip. The 1/16" thick very sticky back rubber that I added to the inside face of the leather belt was designed as EPDM rubber roofing tape. I had to order 200 linear feet minimum. Although my leather belt was properly sized for my cone head pulleys, there was plenty of room on the inside for this rubber. It was not necessary to remove the belt to install the rubber. It only took only minutes to install the cut-to-width rubber. The rubber does a great job of reducing slippage and increasing the driving power of flat leather belt driven lathes. I offer it because I have some left over from the EPDM roof I put on my shop. I can supply it in 5" width by most any length at $.75 per square inch. I made a jig to cut it and I can neatly cut it to width for you at $20 for smaller lengths, more for longer lengths. Without the appropriate jig it is difficult to cut neatly. Order a little extra length to make sure you have enough; do not stretch the rubber during application. I recommend that the width be slightly less than the width of your belt; you do not want the very sticky back protruding beyond the edges of the belt. It does not matter if you use a Clipper belt lacer, a glued joint or hand stitching; I put the rubber right over the joint to give a continuous gripping surface. Rubber lined belts run very quietly and have lots of driving power. You will find yourself cutting at higher speeds and taking heavier cuts. You will enljoy the quieter, more efficient performance of your lathe. This is probably the most cost effective improvement you could add to your lathe. I have now added a rubber face to the above lathe; wow, what power!
Flat belts have become difficult to find. These vary in age, but all are old. I use one on my threading lathe that is about as old as these. Leather is intertwined fiber; it is extremely tough and holds up really well. While repairing a camera recently, I wanted to remove the remains of a leather belt from underneath a rivet; that leather was so tough that I gave up and ground the rivet off in order to remove the leather underneath. Most belts are composed of multiple strips of leather joined with glued scarf joints. I have never had a leather scarf joint fail. Many of these belts have Clipper or some other brand metal joiners, which allows quick connect or disconnect. Chances are, however, that the length will not be ideal for your purposes.....unless you plan around the length of the belt. Personally, I hand stitch belt joints using waxed Nylon cord thread because the length of the belts I use is fixed. I sold the Clipper belt lacers I have had. I will supply a short piece of rod for those belts with metal end pieces that require a rod for coupling the ends together. I measured the length by laying the belt down alongside a tape measure; the belts likely will be longer when under tension in use. My threading lathe belt is a great example of that. I measured the thickness in one randonly chosen spot on each belt; the thickness may vary a bit over the length. Width should be fairly consistent over the length. Do not give up on flat belts and convert your lathe to V-belt drive because you will destroy the value of your lathe. Think about it: someone had to disassemble the spindle in order to mount that V-belt on his cone head lathe. Respect your machinery; leave it as it was designed. Flat belts were good enough for our forefathers and they are good enough for you and I. A properly mounted flat belt will serve you well. Round leather belts are often used on sewing machines and jewelers lathes.
