Yeah, I've really grown to love Al in the past year or so. Bet that 10 was just tons oh fun bending. Have a car here I'm anxious to put 6063 exhaust on to see the difference in weight lol. The tank's probably a little heavy, but won't oxidize nearly as fast.
I have access to a 175 ton press brake and lasers so the cutting and bending really is not a big deal. I would love to buy a new welder for home, just can not justify it at this time. Mine works on aluminum I just have to try a lot harder to get the same results as a newer syncrowave or dynasty. My buddy has a dynasty and he can't believe the welds I lay down with it.lol I tell him if you get used to using my old 900 pound giant this new stuff is like cheating.
