Ernest,
  I have all but completely given up on the aluminum tank for this application.
  That is why I am looking for other alternatives.
  I even looked into rotational molding, which would have been an ideal solution except for the cost of the mold.
  After much labor the alum. tank was at the point where it held air pressure for over 40 hours.
  Then I put 5 gallons of fuel in it and it began leaking in at least half a dozen places.
  Not bad leaks mind you.
  Almost undetectable little weepage.
  Not even a drip. But leaks none the less.
  I've pruven to myself that I cannot weld aluminum with a oxy/acet torch.
   
  On a positive note I have iterated the design of the tank so many times (in Autocad) that I have a much better design (shape) now, at least for my application and can't wait to build it.
  It will be close to 50 gallons and have the Cof G much further back than the original design.
  It will also allow for more usable fuel.
  With the former design I would have had to keep a minimum of 10 gallons to prevent unporting the outlet. I wanted to reduce this to a more reasonable amount of un-usable fuel.
  I'll let you know when N11XD is back in the air.
  Jim

Jim, did you give up on the aluminum tank?
I've been hoping for a message that you were flying again.
