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.
