I have been getting pretty good with my welder, I am making a jig to line up the receiver sections for welding. The jig will be a block of aluminum milled to fit inside the bren receiver with copper plate directly under where I will be welding. I guess I caught the bug, I also purchased a 1919A4 parts kit to make a semi auto beltfed.

Other notes, as I do not have a mill, I have taken the ill advised route of using my drill press and a cross slide vise as a light duty mill. It is barely stable enough to make the cuts from the aluminum.
