DIY gastanks conclusion

["atrav" <atrav@vcmails.com>]

Well, it looks like 5052 is the way to go for gastanks. The final argument, 
5052 is cheaper, quite a
bit via my local metals place. So, 5052 is more easily formed, less crack 
prone, very weldable, and
cheaper, what more could I want? ;o)
I'll probably use 0.055" thick sheet, with 6061 for the angle mounting brackets 
and the fitting
bungs.
