Mystery Attachment Identification - help, please.

Folks,

Got a mystery part that came in a box-o-bits. I've looked online - but be darned if I can find out what it goes to. The one clue I have is the box-o-bits had a lot of Hardinge and Monarch items. Have a look.

Believe this would have originally been grey, rather than the blue. As for scale, the critter will fit in the palm of your hand. The clamp/lug on the base is 1/2". Seems very well made, suggesting not made in China. Fasteners are SAE, not metric. Only marking is the numbers "30" on the base.











Many thanks!

It could be the tailstock off a small indexing set that had its own cast iron base to run on. I had such a set by Brown & Sharpe years ago. It had a simple indexing plate,and tailstock,and would do about 12" between centers.

Excellent, clue, George. I'm off searching for more clues based on that one!

Could be off of an J & L comparator. Far as that goes, any comparator.

Is the quill spring loaded by chance? The rear being a bigger diameter makes me think it could be. If it is it could be a tail-stock of a centering machine. You know where you would put a shaft or test bar in between centers to check the roundness or TIR. The original owner maybe bought the Hardinge without a tail-stock and he started collecting until he bought the right one. I have a barn full of deals like that I bought at auctions for that project I was always going to start and didn't...ha ha Rich

4GSR - the shop did have a comparator. Good suggestion!

Richard - not spring loaded. Previous owner would have bought the machine new - with every option possible! So doubt it was a random part.

Thanks for the clues, folks - am Googling against this new input.

George's clue turned up dividing heads/indexing sets - and indeed this could very well be a "footstock" from one of those. By the way, the boss on the bottom is far too small for my Bridgeport table T-Slot(s).

Looks like an adjustable stop for the long axis on your lathe. That way you would turn to a repeatable shoulder every time. Just thinking out loud...

My guess on that would be the movable center on a Bench centers. They are usually spring loaded but that one adjusts with a rack and pinion. My 2 cents.

with the blue color it may have fit the engraver table???

An adjustable stop would not have a pointed end,but rather a flat end.
