Hi all, new to posting on the forum, I've been here a few times in the past to do some reading, love the historical content and discussions there of. Anyway, I'm in the process of building my own semi-auto only, NFA Form 1ed, H Lebman colt mini replica (though not on a period colt as this going to be a shooter). My questions are related to how the TSMG grip is mounted to the 1911 frame. I've seen several of the replicas members here have built, but i've never seen or read how the originals were mounted. On this forum, ive read variations of attachment ranging from riveting, to silver soldering, to tig welding the grip mount on. I like the idea of solid welding as I want the front grip to be SOLID when handled a lot even by only the front grip. I was thinking of cutting a nice tight fitting notch in the rear of the shortened grip mount that fits on both sides of the front of trigger guard, up where it sits next to the rounded under side of the frame and welding the top part of the mount to the rounded lower half just above the trigger guard. these welds would be covered by a modified TSMG Grip. What do you folks think of this method? Am I crazy for wanting to weld it? Is there much risk of stripping out the threading of the grip bolt and the grip mount and not being able to repair? Is this a safe place to weld on the 1911 frame or do I risk the frame warping from the heat? I plan to modify a new manufactured Thompson grip mount which are fairly $$ for what they are, and want to make deliberate plans before I start cutting and welding expensive parts. Thanks for reading my post!
