I just finished my first build, and was terribly excited. It functions perfectly, and everything fits. Now I see a BIG problem. Appearently, my annealing process was less than perfect, at least on the trigger pin hole. I have an 1.5" long crack going up from the small hole. Is there anything I can do to repair it, so I can at least run a couple hundred rounds through it?
I thought about spot welding a piece of shim stock inside the reciever, then drilling a hole for the pin. Or could someone skilled with MIG, TIG or wire feed welding weld the crack up? What about brazing? Any help would be appreciated. If you are a welder in OREGON who would like to give it a try, IM me please.
I hardened it with MAPP/OXY, then annealed it with just MAPP. I thought the blue color looked right. Then I put it in the oven at 500F, and turned it down 100F every 20 minutes or so, then let it cool in the oven. Do you thing I got it too hot, or not hot enough? Should I skip the oven step? Thanks for any help/suggestions. I'm pretty bummed, since it is my first, and other than this it works great. I would just like to be able to fire it. After a couple more builds, I would probably rebuild it once I knew my system was working right.
