    Wanted--one inch arbor for Hardinge TM/UM mill

    I have an extra OEM Hardinge one inch arbor. With the arbor in my TM and the overarm in place, the runout at the overarm end of the 1" diameter is about .003". These arbors are not used without the overarm. The three longest spacers are original and the other two are replacements that fit...

    Micro Motor and Controller questions

    I used Foredom and Fingst flex shaft tools for decades, but tried a 50,000 RPM micromotor around fifteen years ago for a particular job. The micromotor is fast, light and handy, so I bought more types of handpieces. I still use the flex shaft tools for some things. NSK is an excellent and...

    5/8-24 UNJEF bottoming tap or ID thread tool

    According to this description of UNJ threads, a normal 5/8-24 UNEF tap is the tool to use, but you may need an oversize tap drill to clear the male 5/8-24 UNJEF part. https://www.threadcheck.com/whats-the-j-in-unj-screw-threads/technicalinfo/#gref Larry

    Two DV/DSM 59 questions

    The key needs to be there. Keys can be removed or fall out, but they do a job, so make one. I have seen that bed-mounted vertical cutoff slide on eBay, but never owned one. They are rare and not valuable. The spindle nose cutoff works fine is is common, so it is probably a newer and better...

    Rohm automatic drill chuck

    I have both in several sizes, bought around 1980, made in Germany and cost less than Albrecht at the time. They work OK, but I seldom/never use them any more and cannot say whether they go to "zero" because I do not have any "zero" size drill bits. The one I use most is a 10 mm capacity Supra...

    Geometric threading head Jones & Lamson Model 20S

    it already is thought someone would need on on this forum so I offer it here as well. You mean, you are trying to "help people?" Have you read and understood the site rules? We are not very fragile, but are aware of the site rules, which are in the following link...

    UN thread designation

    If I was given a print that said, "17/8", I would first scale the print to see if it is a typo. Either way, I would suspect incompetence at the source of the print and exert caution in any business dealings. Larry

    Early Watertown NY Lathe

    I have collected a few old handmade metal-cutting drill bits with various size tapered square shanks. Perhaps the early lathes used such drills. Larry

    Geometric threading head Jones & Lamson Model 20S

    Apparently, you have Jones and Lamson model 20S die heads. State the name and whatever else is actually marked on the device. It would be best to post pictures and state dimensions, like the shank diameter and the capacity if you know it. If the chasers and chaser holders are with the heads...

    Geometric threading head Jones & Lamson Model 20S

    Geometric is a separate company/tradename not connected with Jones and Lamson. The two companies' die heads are quite different from each other. In other words, your title is confusing. Larry

    Turning radius on hardinge hc chucker

    The original name for those tools was Shaplane and they are still made. Old ones can be found on eBay, but they are not cheap. https://www.penntoolco.com/eagle-rock-shaplane-radius-tools/ Larry

    Turning radius on hardinge hc chucker

    Hardinge made a "BA" bed adapter that fits the HC bed between the headstock and carriage. The top of the BA has a small dovetail (same size as the DV/DSM lathes) that allows the radius attachment or the slide rest for a DV-59 or the lever cross slide for the DSM-59 to fit and sit at the correct...

    Metal finish question

    I seldom discard a tool, so I looked in my slip stone drawers and found the two "Scotch stones" I had bought circa 1965 from my watch tool supplier. Forgot what they were supposed to be good for. They are kind of soft, look like speckled slate and have circular saw kerfs on all sides.. I have...

    Metal finish question

    I have seen some 19th century scientific instruments with that sort of finish on the flat brass parts. I think I saw it called "snailing" which seems right if you picture a snail wandering randomly over the surface, leaving a track. It looked like it was hand done, but I do not recall seeing a...

    The 6" x 48" belt/12" disc grinder is what caught my eye. I have one and find it useful. It is small enough that it will probably sell for more than the drill. Larry
