Is This Tailstock a Cincinnati?

jwearing · Apr 26, 2019

I picked up this tailstock a little while ago from ebay. It looks like a Cincinnati, but it is small, about 3-3/4" to the top of the casting and about 5" to center at max adjustment. Looks like it would fit an 8" dividing head, did Cincinnati ever make one this small? Did any other manufacturers ever make one this style?

The dividing head in the pictures is a 10" Cincinnati.

That's a tailstock for a Toolmaster mill index head. The "6JKA" indicates a Toolmaster, and the "5C" is a 1955 build year. The Toolmaster had a unique indexing head.

If you ever want to sell it, I'm interested.

Mine measures 5", other than that it's identical. No name on it, but came with the Cinci head.

Wow, that was fast. Thanks. I didn't know these existed, that's interesting. Is this the head? unknown dividing head

I don't really want to sell, however I would be happy to trade for the correct tailstock that goes with my 10" Cincinnati. Or if you have a spare set of high-number plates

Thanks. Yeah, these are really distinctive with the two-point centers.

Yep, that's the head. I remembered that thread, but couldn't find it to post the link. Thanks.

Sorry, I don't have a Cincy horizontal mill tailstock or number plates to trade, but they're out there, and more common than these Toolmaster index tailstocks. Yours is the only one I've ever seen. I've been using an LW index head with my Toolmaster, but would like to find the OEM setup.

Over priced and they dont list size. It looks small.
It may not even be Cincinnati. MAKE OFFER. No connection to seller

I think that the OP is looking for a dividing head tailstock (aka footstock). The one in that ebay listing appears to be for a very old Cincinnati (maybe) engine lathe.

Lathe serial numbers are on top of the tail stock and the bed and the front flat and the V ways.
