Hi Nick. Looks like you've had no response yet to your post. For some reason the forum has been preventing me from logging on for a couple months. Just logged on this AM.
Since I can't yet weld aluminum, I pro sealed and riveted my tank flanges ala the RV series of planes. I don't know if my method would also work when welding instead of pro seal and rivets. The openings I made in the bottom pan of the tank were maybe an inch dia. Then I pro sealed and riveted through the flange into the skin. Would not welding be possible the same way? That way, you end up drilling the large diameter hole in the wooden floor of the C section instead of the tank. The depth of the flange below the bottom of the tank skin pretty much matches the thickness of the C section floor (my floor is made from Finnish birch and is either 3 or 5 mm which ever is closest to 1/4".
But then, by now you've probably figured something out and welded her up. Good luck!
