No, alas the guy from Spokane builds many more riveters than firearms. It was used by a FFL/SOT to build a Post May Dealer Sample. He had a much easier time building a MG-42 since he could just use the parts as they were meant to be used.
I do drag out my '42 kit once in while to look at the parts. I am planning on making a jacking screw similar to Hcpookie did, but use a piece of bar instead of the coupling nut. I think Tanker on 1919a4 adapted his 1919 wedge for the mg42.
