IT'S ALIVE!
Sorry for the radio silence. I finally got out to a private range to get some footage. 



These clips are within the first ten rounds fired, so I hadn't gotten the hang of reloading yet. I found that it's really easy if you point the gun downwards and hold the round from the rim. Unfortunately, my cameraman was having some issues so the rapid-fire clip was lost. Anyway, I put over 100 rounds through the gun with no issues and no significant wear:
Here are the spent casings from the bulk Federal that I put through it. Note the many variations in case deformation. I have to say I'm very proud of this pistol!

I'm planning on doing the hardening and finish during Thanksgiving or Winter Break, and I'll post another video when it's complete. Also is there any interest in blueprints for this? It's a little bit of work to convert the 3D models but I'll gladly share if anyone wants it.

Sorry for the long wait, I was only getting little portions of the project done each evening, so it wasn't worth it to post every night. Anyway, it was time to start shaping the front of the barrel. For my very crude setup, I put some Gorilla tape on my vise jaws and then clamped the barrel in between. I used a steel rule to line up the small edge and rear of the barrel with the top surface of the jaws:

Yesterday I got to work on the sear slot again. I used cutoff wheels on the Dremel again to get most of the material out. Unfortunately the cutoff wheels don't fit in the slot the short way, so I ended up using them to grind away the entire rectangle.

Yesterday I got started on the slots in the receiver. The receiver needs a slot for the frame hooks, rear tower, sear, ejection port, and charging handle. I started with the hole for the front hooks. Originally my design called for a thin slot for each hook, but I realized that none of my files would be able to fit in the 2mm-wide slots. I could use just a Dremel, but I wanted a better finish so I just resolved to cut out a square.

Today I got started on the trigger guard. Here's the model:

I got a very late start today and didn't get as much done as I had hoped. I started off by making another spacer and riveting it to the frame. Then I went back to the barrel. Here's what it's supposed to look like:
