Awesome lookin work man... I can't bring myself to have the patience for sheet metal work, most everything I do is in 3/16" or heavier!
i want, nay, i NEED a plasma cutter.
I'm green with envy over that Tube Notcher. Forget everything else, that's the one tool I really whished I had when doing my tube work (Chop saw/angle grinder notching sucks!).
