I think I'll try doing a semi without waiting for these semi options being offered on some of these boards, I've looked at the build photos on Weaponeer and the MG 42 board and it doesn't seem too tough. However, when I started working on the bolt I discovered that sucker is HARD, I mean extreeemly hard. Any thoughts about how hot and for how long I need to keep it hot to aneal it so it can be worked with HSS and carbide. I can mill it with carbide for the denial block by taking light cuts and lots of coolant but I don't have carbide drills that would work.
Since this thing is a pistol cal ctg, a hot one at that, any thoughts about re heat treating after all the work is done ?? Are all of the different makes of these that hard ?? I think my kit came from OOW 4-5 years ago.
Thanks in advance for any ideas, thoughts,or help, Lon
