    I think I recall a Fred Dibnah video in which he used a hand pumped air horn to warn spectators that the chimney was about to fall. Maybe the horn was repurposed boating gear.

    In 1946, the ESM and TR underneath drive split bed lathes were replaced by the dovetail bed lathes that became the DSM-59 and DV-59. The first few years of the dovetail beds were machined on the...

    I drive a 1940's Hardinge flat belt 59 lathe with an older Rivett three-speed (high forward/low forward/reverse) counter. I built the bench and drive about forty years ago and lowered the jackshaft...

    Todd, I am sure you have been going to Yoder's (Holland, OH) at least as long as I have and must have been there much more recently than I. Their dozens of file cabinets of literature were unguarded...

    Looks too new to be associated with the Marse Robert books. Hope it is inert.

    The Hardinge HCT chucker with chase threading is perfect for cutting large fine threads, like the optical industry often needs. I think the machine was mostly intended for that class of work. It...

    I have a TR-70 that I use. It does a great job on single flute or fluteless countersink bits. The wheel is a common 6 x 3/4 straight fine grit white aluminum oxide. I did not take the wheel off to...

    I had bought the Enco Swiss-made 40-position set around 1980 in their size E-2, the same as A size. The holders have the OEM stamped Axxx marks plus ENCO E-2 chemically etched on the side. I spent...

    I have a box of new and used Hardinge 2VB collets to fit that mill. I probably have sizes not included with the mill, and some other odds and ends of tooling for it.

    Hardinge stamped the serial...

    Some decades ago, I let a stranger into my shop to sell him something. He was so impressed with my obvious ability to "make anything" that he disclosed his idea for a perpetual motion bicycle. It...

    Here is an example of why a Taiwan copy may be chosen, even if the new owner would rather have a Hardinge. First, Hardinge stopped making them. Second, Taiwan shops still make them. Several years...

    The picture is unclear and does not define the finished part. But to answer the question, I would use my Levin 10 mm lathe with the lever cross slide and turret.

    I think all HLV-H lathes have magnetic starters from the factory. The OEM motors are two-speed, so they have two different current ratings depending on the motor speed. Overload protection is built...

    What difference does knowing which Taiwan shop made the mill make?

    You could ask Rutland, which was bought by MSC years ago, but why bother?

    I started buying from Rutland around 1970 and they...

    I think Severance makes rod-end chamfering burs in various sizes. They will be a lot better than the thing in the Amazon link.

    That is confusing. My old Hardinge collet list just shows 1AM and 3AM collets used in Ames lathes and mills. Neither one has a 20 mm (.787") body diameter.

    I know essentially nothing about Hendey lathes except that they were good, but I am always willing to learn more. See, I have owned four different 12 x 36 engine lathes. The first two had 1-1/2-8...

    If you get a 1/2" collet with the mill, you can buy a small boring head (possibly with 3/8" tool holes) with a 1/2" straight shank. You will need boring bars to suit, either HS or carbide tipped,...

    The American Precision Museum has a gear shaper that they can run to make small brass gears while visitors watch. They can stamp their name on the gears to make souvenirs.

    Yes. Cranking the knee is not a good way to drill holes. It is slow and accelerates wear on the machine. Small drill presses are much better suited and should be quite cheap for one that will do an...

    The answer is, slightly larger than the exposed part of the ball. I suspect that different makers use different size balls, some inch and some metric. The only "standard" dimension is the 1/4 inch,...
