Having just finished the tanks for my RV-7, I agree with Cy. If you're
in the USA, call Van's A/C & get the name of a builder near you & go
look at the plans for the tank/leading edge to get an idea of how they
go together.

If you can handle cutting & fitting the aluminum, the rest is pretty
simple & you can build with a drill & a cheap 'pop' rivet tool using
closed end pulled rivets. AD41H aluminum body steel mandrel is what's
used to attach the back baffle to the ribs. You'll need at least a
couple of internal ribs to stiffen the 2x4 foot top & bottom panels.

The hardest thing will be bending up the 'box' but a good sheet metal
shop can do that for you. (Be sure to tell them to use the proper radius
on the bends.)

You will be amazed at how light it will be.

pro-seal. If you know a good tig welder, then a welded tank can be built.

. . . so I'm going to have to learn to build an aluminum
tank..

Anyone know of a resource to show me how?

The books by Tony Bingelis have excellent tips on this.
