Do you know what this is? See picture.
« on: November 28, 2008, 08:55:13 AM »
Bought a secondhand lathe (AI hembrug from the Netherlands), a beautifull machine, and a small mill.
With it came a lot of parts, tools and equipment.
After a lot of puzzeling most of the things are clear, so i know how they are used, or what their purpose is.
But three parts are a mystery for me.
So have a look, and perhaps you know a thing or two about it.

First two pictures:
This is some sort of collet, but the three parts are not separated, so it is not possible to clamp something in it.

Can you post a pic looking along the side. If the back part is a collet, then you could just mount it in the head of the lathe and use those three slots along with some custom clamps to hold odd shapes or mimic a three jaw chuck.
Do an internet search on jewlers lathes and you'll find all kinds of stuff.

as you can see the inside is still connected with the outside, so you can not force the three parts to the inside and clamp something

It's a blank collet. The face should be soft, thus you can machine the face, like incremental rings which would hold by id or od. You then drill a larger thru so you can draw it up with the bar.
You can make a holding jig out of it or whatever.

YOUR REPLY #4,
i think that mates to a cam lock type mounting plate and can repelace the chuck . Don't know about the inner boring, check if any other pieces you got a a matching profile .

That actually looks like a vacuum table/fixture of some kind.

Is there a tapered threaded hole on the side or bottom for an air fitting?
