[QUOTE=Perry Made an insert to shoot 223's out of a 12 gauge[/QUOTE]
What?
I'd like to see a shot of that piece.
I've run quite a few old turret lathes that predate ww11, perhaps ww1.
I was always fond of Geisholts.
The place I retired from had some ancient relics still plugging along.
Not too many years prior to that job they still ran many of their machines from belts up to the ceiling. I think a steam engine generated power.
A lot of war parts made on the same turret lathes I ran for many years.
