I learned a trick, probably from lookin at tools and such in the Brownells catalog .....which sits in a place of honor next to my throne.
I ended up makin a hard wood block with a coupla holes the right size and spacing to make a trigger/hammer jig fer helpin with trigger jobs.
I used a piece of paper on the side of the gun to get a pattern of the holes for the hammer and trigger and used the pattern to drill holes in the wood block.
I drill the holes tight for the hammer and trigger screws and a little wide for the shank and less wide for the threads at the end.
All I had to do was screw the screws into the hard wood block to have a jig fer that gun that let me set the parts on it screwed in and SEE what the heck I was doing.
I could see ifin there was negative or neutral or positive engagement angles on the trigger and hammer to set a good trigger job.Make that,"breaks like a glass rod", kinda trigger let off that's the safe kind. In my opinion.
It only took a matter of minutes to make the wood trigger job block jig (since I had some blocks about a few inches square and a coupla inches thick). I won't mess with a trigger anymore, since then, without the hammer/trigger wood block jig made first for each gun(cap&baller). Even if all I want to do is polish or smooth up some.
I wouldn't want to smooth up a trigger that had neutral or negative engagement to it.
I won't even smooth up or polish without makin a block jig first. I wouldn't want to make one for a semi auto though.
Anywhooooo.....anyone can make one of the hammer/trigger wood jigs fer a trigger tune up. That way to "see" what's up and make a safe but nice trigger......instead of polishing and gettin closer to a hair trigger.
