    I have some Leinen watch lathes, but have never seen one of their engine lathes in the USA. They certainly made good kit, so condition and completeness will decide the value. Tony does not show...

    It is a watchmaker's staking set. Kendrick and Davis was the most popular brand. Marshall was a large jeweler supply house, but their staking sets are much less common than K&D. Probably the...

    Hardinge Cataract headstocks made from 1903 to 1930 had those rotating oil covers. I don't know who made them, but Gits is the usual suspect. Here are pictures of a Cataract 59 headstock showing...

    It is called a flat cap in the UK and has other regional names. I got one in 1967 to wear when I drove my MGB with the top down because it resists being blown off your head in wind. I still have...

    Click on his name and you will see that Steve's last post on PM was on 3Dec2006. Maybe someone else has the file on their hard drive or the cloud and can help.

    The threading chart for English (inch) and metric threads shows the 127 tooth gear is used to cut metric threads. So it cuts threads and the leadscrew has an inch thread. I would guess that the...

    I certainly can sell you a good working unit. And I can probably salvage some parts from the mess that was made of your original closer assembly. I cannot guess why the tube was cut or what...

    A good used Hardinge HLV-H-EM would do what you describe, or a new Taiwan copy (Hardinge stopped making them).

    There are cheaper machines, but few better machines. If you buy a $2000 lathe to...

    It helps to have a small precision mill for doing small precision parts. My Derbyshire Micromill was built around 1945, but I finished rebuilding it and converting it to vertical a few years ago. ...

    Hardinge built foot rests into some of their machine bases. The HSL-59 speed lathe is an example. They also listed industrial stools with backs (not made by Hardinge) in their catalogs. I suppose...

    I have not bought stainless bar for a long time, but what I bought arrived perfectly clean. Maybe you should ask your supplier about cleaning before shipping, or ask other suppliers.

    A different approach would be to start by precisely measuring the hole locations in the mating part and make a drawing. Apparently, the end result is to have larger tapped holes that line up with...

    I think Ser. No. 7171 was a number in the general machine number series, not a number indicating the specific ranking within that machine model, like the numbers Harold mentioned.

    Yes, the lathe is top heavy even without the overhead drive. It is a lot less work to take it apart than to deal with broken castings and bent cranks.

    More important is whether the jaws grip a straight and round rod evenly along the jaws' gripping surface, so that the rod does not wobble as the chuck rotates. A wobble like that is very hard to...

    I like the TDR/SRD model DG-80M for 1/16" to 13/16" drill bits. No collets required. It takes two minutes to learn how to mount the bit in the V-block chuck and another minute to adjust the motor...

    It is much older than the 1940's TL model. Note the Chicago on the cast door. Hardinge Brothers made lathes in Chicago from 1903 to 1929. In the early 1930's, the Hardinge lathe business moved to...

    I expect few people here have ever seen one, so I took a picture of the ends of two different failed tensile specimens. I pulled them out of a scrap bucket at my engineering school, around 1960. ...
