At the first local two day CAS event, what could go wrong - did!
I ended up with the wrong size caps for new cones I put into one of my .44 Remmies. Took 2-3 hammer falls to go "Bang" on some chambers. Won't do that again ....
Before my wife fired her first shot, the trigger/bolt spring broke in one of her .38 Spl. Uberti Stallions while she was loading. Good thing I had brought along extra guns, my old Ruger Vaqueros in .44 mag.
Back home, I managed to fit a spring for a '51 Navy to the Stallion. I had to shorten the trigger arm and narrow the width slightly to fit the frame, but it works. New springs coming.
But the gremlins did not go away ..... in removing the grip frame, the little spring on the right side took off when I removed the screw. I finally found it, only to loose it again!
I removed EVERYTHING on the bench, searched the floor with a flashlight on my hands and knees and couldn't find it. I made up another by trimming a spring, but it was too powerful. Standing there scratching my head (I THINK it was my head), my wife showed up to check on how it was going and said - "What's that?"
She saw the spring behind a spray can of lube, one of the several cans I had previously moved THREE times before! Ever have one of those days ..... ?
