Suomi M31

[patracy]

Since I'm at a standstill on the M2HB project until the extractor cam comes in. I spent the day making up the receiver parts needed for these.

The tube needs a 37mm thread. Unfortunately my lathe doesn't turn metric threads. But a 20tpi thread worked after several passes.

Next I prepped the left over receiver parts.

Next I used the cap to figure out where to mill the flats.

Opening up the tube for the trigger and charging handle.

I put it back in the lathe to figure out where the sight needed to end up on top. I just scored a line to know where to mill the sight hole.

First one laid out together.

And what's better than a sub gun? Two sub guns.

Waiting on some parts for my welder now. But they're ready to TIG.
