Guess what chuck these jaws belong with

[skogkatt007]

I guess 1 (of the 4) could be missing. As a possibility.

No idea what they fit, but looking at the picture, clearest in the picture at the "tall" end of the jaw, the teeth appear to be both staggered, and "crescent moon ish"l. That'd make it a scroll chuck. You could probably measure this, but the "offset" of the first (or last) tooth relative to the jaw body, see how the offsets work out. If a fourth offset would put the teeth in line with one you already have, it's a three jaw. If the three offsets you have there have a "hole" in them that needs another jaw to make a set.... Then it was a four jaw scroll chuck.

Hardinge 3 jaw 5 or 6 inch ? I have 2 sets downstairs . Take measurements to compare .

Dollars to donuts, the jaws are from an import scroll chuck
Most likely a 3jaw chuck

They should be marked with corresponding #s and by the looks of it they are . Outside jaws for a 3 jaw . Take the measurements and post them .

Look very similar to the import 5" 3 jaw ones that came with the chuck that was included with the Brown & Sharpe "0" knock off dividing head I bought a few years ago. Key looks the same also. Mike

Commonly orphaned when the lathe is sold with the chuck but the second set of jaws is somewhere else. Usually sold by a family member of the deceased owner. Not so common to get the chuck key.

Bring the tips of all the jaws together- that would tell you if it's a 3 or 4 J

I don't have these in my possession. I spied them on craigslist, seller didn't know. A Hardinge pdf showed up first in a goolog search. In any event they don't seem to be for an 3" AMA chuck. What I need.

Is there anything that you do NOT have downstairs?
