[quote="walkerheaders"]I copied several sets of drawings i found here and went with the most current dated. I sure hope that doesnt bite me, since my kit (and drawings) will be here in a few days.
I have only machined the bolt parts so far. I have several sets of extra parts if need be.
My late brother bought lots of de-mil over the years. he had big plans to make something from all of it, then got too sick and left it behind. I'm the only person who knew what any of it was. ( several MP44's, MG34's, MP40's, G43's an MP30 etc...) his estate thought it was a crate of torched scrap metal. I got them to deliver it to my garage.
I sold some of the kits and parts over the years that i couldnt use, still have a few left.
So, I am starting with his MG34 first. he tried to get this one together, but never did. (so this one is important to me)
I am not a gunsmith, but a lifelong fabricator of chromemoly and exotic racecar parts, also i work in the Robotics Division of General Dynamics as a master technician.
I dont know exactly what i'm doing, so i'll watch you guys and try to follow along. (also a GIANT thanx to PIRATE's tutorials)
it's hard for me to feel like working on my projects after all day at work. I could stay late and use the good machines, but my old bones get tired.
at home i have a semi- cheesy chinese hobby mill and lathe. you can see in the pictures. it's good enough for the mods I have made so far.
cutting the main slot with a carbide burr and some wax. I took my time and it turned out very nice:
next i made a tool to hold the firing pin sleeve into the lathe, and mounted (and squared) the dremel onto the toolpost:
after some careful measuring and getting the speeds right, the slot came out nice:
then rough cut the sleeve to length:
tool and finished sleeve:
rough cut the length of the pin lock nut with a large cut-off wheel in the mill. I finished it with a honing stone and deburred real nicely:
I rough cut the bolt length with a 3/4 carbide endmill then finished with a honing stone and deburr wheel:
I cut the chamfer on the back of the bolt carrier to specs with a 3/8 carbide endmill, but it may need more removed later:
