Sigh..thanks. I just came in from the shop, and had stood there for
about 30 seconds when the light bulb came on above my head. I felt
like an utter idiot when I posted this..and a bigger idiot when the
light bulb came on over my head.

Now Ive got to grind an ID tool. That I think I can manage....
I checked my threading tools..nothing for ID..dont know where they
have hidden themselves this time.


Be sure to give yourself plenty of front clearance, ID threads need more of it
than OD threads.
