Ken If I were you, I would forget about trying to locate those missing jaws
and just go with what you have. As to grinding chuck jaws, I do it maybe
once a year for the same reasons you are having trouble. I will photograph
the setup I use on my Atlas lathe using a Craftsman heavy duty hand grinder.
Think Dremel® tool on steroids, lots of steroids in fact, but you can use an
el cheapo air die grinder just as well, maybe even a Dremel tool if you go
slowly.(Maybe a whole case of steroids!)
