A little progress.

We have completed the validation process for the top and sides of the receiver and milled out two of them. The bottoms will be done inconjuction with the trigger plate. We EDM wire cut out the first two trigger plates as you will see in the pictures below. However, as it seems is always the case, the computer that starts up the EDM failed and now we must find a replacement. The next step is to EDM wire cut the other plane of the trigger plate. As you will see below they are cut to shape in one plane but not the other-------------yet. We are dead in the water until the EDM is back in operation. I suppose we could mill off the rest but the EDM is so much faster and better. I will just have to wait--------------again.

This is one side of the receiver fully meeting all requirements. No polishing has been done so you see all the tooling marks.

The other side with just a tiny bit of polishing of the tooling.

The trigger plates EDM wire cut from the host block of 4340 steel alloy.

A shot to show the comparison of the planes.

A picture of the trigger plate to show it relationship to the cut out.

Other side of the trigger plate to show perspective.

Hopefully I will be back in action before too long. I will post more when I have them.-----Bill
