Chuck back plate
Lathe 4 jaw chuck rear.jpgThis chuck has been machined with the two surfaces shown by the green arrows, level with each other.
As it is impossible to source a cast iron back plate, or a suitable blank, I have started fabricating one, and I though it might be an idea to cut a few thou relief in the back plate surface, to make one of these two surfaces, the contact surface, rather than have both as contact surfaces, and I am leaning towards the outer.
Good idea, bad idea, doesn't matter??
