I cut my sear bar a bit too short and need to extend it. I ground about 3/8" of the end of the bar to about half its thickness and did the same to the bottom of an old drill bit that is about the same diameter as the sear bar. My question is on how to join them. Since the trigger bar will be pushing on the drill bit extension and causing some torque on the joint, I don't want the joint to fail. I have some low temperature silver solder I got from Micromark that I have used to solder on barrel underlugs and flux coated brass brazing rods. I have both regular propane and MAPP gas torches as well as a jeweler's oxy-acetylene torch so the heat source will be no problem. Could I use the low temperature silver solder or do I need to brass braze them together?
