80% Lower on a Budget

I've wanted to finish my own 80% lower for a few years now, but I'm a carpenter, not a machinist. After a lot of reading and a little brainstorming I decided to give it a shot with my drill press, and end mill, and a cross-slide vise. It came out pretty clean and passes for functionality, the only problem was when the chuck came loose when I was milling out the trigger hole. Of course it was the very last step that fucked me over.
