My latest hair pulling session! I started putting everything together and the barrel wouldn't go in, somehow the tang got bent ,I don't remember dropping the barrel on the tang end but it had a pronounced hump where the tang bolt goes through. Out with the rubber mallet and the pounding began. At first I went too far, then too little and finally got it to where the tang would fit in the mortise. It appeared to have a little sideways bend but so my perfect wood to metal fit isn't perfect anymore.
I got the barrel in and started assembling the lock, I decided to file off the fat side of the top flint jaw screw so it wouldn't bind, next I found the top jaw was not cut properly and would bind as well, a file took care of this problem. I put the guts of the lock together and the hammer wouldn't go down on the tumbler all the way. I took it back off and could see a burr in the square hole that fits over the end of the tumbler. Out with the needle files, file and check, file and check for about 1/2 hr and the fit is better but still not right. I have to take the lock back apart and and file some more, I can see where the hammer is binding on one side of the tumbler shaft.
Tomorrow I am going to disassemble the gun correct every little glitch I found on assembly.
