Had a remedial lesson today in why I choose not to do general gunsmithing; I hate dealing with the unknown problems that come through the door that have been caused by bubba and then covered up. A somewhat local guy got my name somehow, as working on rolling blocks. He dropped by and caught me with the garage door open. So, had him come in, and looked at what he had. Nice 7mm action, great condition, reworked nicely with good blue, nearly colorless case, and good workmanship. The barrel was octagon, new, and the workmanship wasn't quite as good. The trigger was probably 20 pounds. He wanted me to fix it. Okay, usually pretty easy. I opened it up and it didn't look like it had been hacked up; the workmanship looked good. So, I told him I would do it. I didn't bother to get either my glasses or optivisor. I should have! Make a spring, install it, and it goes to maybe 1 pound. Oh-Oh. Should be 2 to 2 1/2. Tap it with a mallet, and the hammer falls. Of course. Get out some magnification and start looking. Before they blued the trigger and hammer, someone has "worked" on them. Hammer sear looks like it was recut with a file. Uneven and rough. So, get out diamond files and clean it up and return it to correct geometry. Put it in, and it still falls. Look at the trigger, and it is awful. Sear surface is almost rounded. Both the hammer AND the trigger have been cut to positive geometry, so that the mainspring of the rifle HELPS pull the trigger to overcome the 20 pound trigger spring. So, recut the trigger also to correct geometry. Got it to about 3 pounds and safe against bumping accidental discharge. Way beyond what I want to get into to reharden the sear and hammer. I'll just let it be a bit mushy and creepy, and tell him what work is entailed if he wants to fix it right. I can't believe that people still stone rolling block sears/hammers to unsafe configuration instead of just fixing the spring. Especially someone that did otherwise pretty acceptable work on the rifle finishing.
