Jaw grinding

[bpimm]

The manufacturer probably knows the angle to grind the jaw to for each chuck which would probably good enough for a production situation.

Good for you! I have a state of the art 1909 16x36 Pratt & Whitney engine lathe that I wouldn't trade for the world, worn out would be an understatement! It did help win the war with a tracer attachment to make artillery rounds and the ways are all but gone under the chuck. Grinding the jaws helped quite a bit but ,turning a part around is not an option.

Thanks for the post. I have been fighting jaws that splay out forever, your post gave me the idea and motivation to grind my jaws. In fact, grinding as we speak. Your never to old to learn something!

Thanks again
