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.


Thanks again

Gunner

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

I make 'em by silverbrazing a piece of HSS toolbit on the end of a
boring shank. I do most of the grinding before brazing, just touch
it up after brazing.

Ayup. Did that. Got the "nut" made already this morning. Now to mount
one of the spare mag chucks on the grinder and see what the surface
finish looks like.

Further metalworking:

Buddy came over yesterday with his brand new Savage FTL 10 rifle and
a brand new aftermarket 6.5x55 barrel. I made him a receiver clamp
out of aluminum bar stock (3" diameter) and we changed the barrels
out. Damn thats easy. (He did buy the proper barrel nut wrench)

Don't forget to grind in your mag chuck, not if you expect it to be true ..
