Can you buy pin chucks or are they normally home made. Has any one made one or used one.
This is the sort of thing I mean these look home made.

Having done some googling there is apparently a woodworking tool called a pin chuck, which is a spindle with a flat like the images above, on which is placed a pin. This is inserted into a hole and when rotated in a lathe, the pin rolls off centre to lock the work piece in place.

Never heard or seen it before.

I use a number of the eclipse machinists pin vices, very useful I find.

is the flat, well flat? or at an angle so it rolls and forms a wedge? and then need left handed and right handed versions?
