ok guys I am just finishing up my trigger guard jig and I needed to know your opinions on what to rivit first the trigger guard or the center support. I would like some rational for the order as every body has different ways of doing things. I have just got my test receiver bent in the jig that I got from sprat(thanks again) and I am ready work on my heat treating procedure. I intend on using an acetylene torch set up at my grandfathers shop ( I also have a torch set up at my shop but only have propane/ O2 set up . same set up just different fuel gas. i was wondering if a slightly carborizing flame on the acetylene set up would help to add some extra carbon into the heat treating process? I have a few other questions for you guys after I get a little farther along and I have been saying I will put up some pics but haven't gotten around to it yet . (I will when I have all my jigs and rivet squeezers done) thanks again for all the great advice.
