I inherited a 13" Clausing lathe from an uncle who was a machinist along with a lot of tooling but one thing in the pile has me stumped. I'm sure someone here can tell me what it is.

Looks like a lathe carriage stop, multi position by rotating.

What he said...

Used on turret lathes to set the stops for successive machining operations.

Thanks, anyone need it? I don't have a turret lathe and probably wouldn't know how to use it if I did!

you absolutely DO need it. It is for a standard, manual lathe. It is a Turret Carriage stop and is used if you're going to turn different diameters on material, at different distances (lengths)...i.e. cut first diameter on the end as far in as you want...set first depth stop and then rotate out of the way...proceed to cut next diameter to the next depth and then set that depth stop, etc.

now you can make multiple parts all with the exact same length of cut for each diameter, without measuring the distance

figure out how it attaches to the front edge of your lathe, to the left of the carriage and keep it!

Thanks Scott. Now that you described it's use I can see how it works. I just need to figure out how to mount it.

Normally, there is some sort of a "Vee" groove in the bottom and then a clamping plate dangling from the underside...that thing grabs the "Vee Way" on the top of the lathe and then clamps tightly. That way it can be slid to some relative (useful for that job) and clamped tightly.

show a picture of the underside of the thing and then a shot of the top of the lathe bed and someone will provide the answer (maybe even me!)
