Yes I did the metal work. I have a little mill drill machine, and for this stuff it works just fine. The aluminum cuts pretty easy, and most everything is made from pretty standard shapes. Although I have to admit, I'm a bit of a scrounge. I made the rear swing plate from an I beam that I saved from a patio cover I took down at work, and a couple shapes did come from the dumpster.
Might be a good name for the camera, Dumpster Diver.
