RCBS Trim Pro 3-Way Cutter 22 Caliber
Lee Shellholder 223
Lee Lock stud
Rockwell mill [big drill press]
Kurt vise [ big drill press vise bolted to the mill table]
vise grips [for actuating the lee Lock stud]
That will trim, inside chamfer, and outside chafer a case every couple seconds.
---------------------------
I have also put a Forster outside neck turner on the drill press.
I mounted the trimmer with foam rubber and rope. I need to control the torque and trust, but the center of the drill press quill and and center of the turner must float so they can be concentric.
--------------------------------
I have done outside neck turning in the metal lathe with the mandrel in the headstock and a shell holder in the tail stock, like Mike Bryant:
