I ask because I'm renovating an old chuck, and I need some help
understanding the design..
In my rather battered example, the hinged bronze frame which the lever
operates retains two slipper blocks, which in turn run in a 1/2 inch
wide groove in the rotating part of the chuck. On my example the two
slipper blocks are made from some dark red fibre material, and are
very worn. Wear aside, they look wrong (and home-made) to me, not
least because of the material used, and because they provide no
lateral location. I would have expected them to be made from a
material such as phosphor bronze, and to be more circular in shape.
Someone with one of this type of chuck has told me that their chuck
has a solid circular bronze bearing ring, rather than the 2 slipper
blocks. However, I can't see how this could fit my chuck, so I guess
there may be was more than one version.
I have placed 3 photos of my chuck and the "slipper blocks" in
Photobucket. See

Any help much appreciated.
