Shotgunjones,
Ah yes, good old "safety wire". I spent many hours in the Air Force spinning the tool to secure the aircraft bolts!
I can speak from experience regarding the Merkel screws.I solve that by placing a tiny amount of locktite between the taper of the screw and the taper on the hole of the action.
