Few jaws

[Sergei Slovenija]

lathe chuck jaws preparation for boring.

Holes for pins dia 8 mm, for clamping the ring from the bearing. I make equipment for abrasive boring of jaws.

The jaws are surface hardened, the drill with a carbide tip + coolant coped without prior punching.

Once you have ground the jaws, I wonder if you could re-purpose the holes for jaw pads. See:

Putting a threaded bushing into the hole will not be difficult.

I could not think of a way yesterday, but maybe a headed pin with an O-ring on it would retain the pads but still allow an unthreaded hole.

Would save the grey hairs produced from trying to tap some tough material.

use an anaerobic fixative, for water pipes, I buy some inexpensive one made in Poland. It is not as strong as the specialized Loctite's. It breaks down with a little heat (up to +150 I believe). A reverse hammer will work too.
