The action wrench store was out! I thought I had everything but did not have one to fit this monster Stiller 1.600" Tac408 action. So I had to make my own. Started with a 1 1/4" 4140 shaft. Borrowed Holland's design with his permission and made it to suit. I didn't have the form cutter like he used so the end is flat but it still worked great. Torqued the 1.187" tennon to 150 pounds.
