Building an MP-44 semi part 2

This is the second in a series of post of Pete, a friend of gun lab, building his semi-auto MP-44. From our previous post you could see the absolutely dismal condition of the cut up receiver pieces that Pete had to work with.

You can see from these pictures that there was no back section. So the only answer for Pete was to design the tooling and make a new rear section. This is that post.

In this photo you can see the style of the female die with the cuts for the ribs to be pressed in.

As with all stamping work to obtain the best possible product you must have a flat that is the same and you must have a method of properly locating that flat.

This male stamping die is much more complicated to make then most people think. All this tooling was made on a manual vertical mill.

With any press tool you have to have guide and alignment pins to obtain a quality product.

Pete does all his pressing on a simple shop press.

To fabricate the rear pieces it take multiply set up’s.

Some real nice tooling to make his rear section.

This is not a simple process to make the rear sections.

You can see for this final photo the quality of work that Pete produces.

If anyone is interested in a replacement section drop me a comment and I will forward it to Pete. He has a few of these left.
