Well, after many months and many hours, I think that I'm going back to the original flanging method. I probably could have been done by now if I had stuck with it to start out with. The flanging tool that I made isn't working as I had hoped. It's not very precise and tends to take longer to do one hole than with the Bob stick. Although I think I'm going to make a Bob Stick out of nylon polymer so I don't need to add wax to each hole.
