I am currently looking at doing this......I'd like to do a nose that includes the blish slots and about 1/2 an inch behind them. as well as a M11A1 style with enough to cut a horizontal dovetail on the rear to align with a corresponding cut on the rear receiver piece.....sure would simplify the weld Main thing I still have to solve is the tooling to cut square threads. Currently I dont have a source, but am researching currently. Already have the fixture for the 4th axis sketched out so hopefully in the near future I can make it happen. While some may consider it blasphemy.....I was also thinking about a hybrid for the M1 with slots to accept a drum. I see Kit build rewelds as shooters.....so in my book it is all good If you are able to successfully reproduce 1928 thomspon receiver "patch" sections like you mention, I will be in line for one. That would be great for those that don't want to spend an arm and a leg on a demilled nose piece section to build a display gun or semi auto without going for a P.O. 80% receiver. If I can get a pilot run of them done......I will put a few out here for inspection with the membership......I have wanted to do this for a long time.....just been so swamped with Macon Armory stuff (45,10mm,and 9mm) AR stuff i haven't been able to....Gotta pay the bills. But I am at t point I need to start having more funn and less 60+ hour weeks..... added impetus is I have a 28 cut reciever set that I have earmarked for the 7.62 x 25 bolt and barrel set I have. I am dying to get a Tokarev Tommy runnin....
