Bartamos;
I'm intrigued by your idea of making a wooden buck to make tanks with. Pardon my ignorance, but what exactly is a buck. Is that a block that you bend metal over (wood on the inside).
YES
Plenty of info on bucks on the web. It's just a "negative" to make a "positive". If you have ever seen the wooden inner structure for older aircraft wings, for instance, it is like that. Wooden spars and ribs and all manner of ways to create a mold/form. If you screw it all together it will be easier to tweak various pieces. You will need a real tank to measure.

The tank can be "rolled"/formed by a sheet metal person and all bent out of one piece (I'm talking one half of the tank) folded up and welded. This would take several cardboard mock ups to get what the sheet metal flat pattern would look like before bending/rolling.(there are computer programs for that) The Burb/Panel tank fits into a couple of radiused cross members where they meet the frame channel, as you know.
If you ever get serious about making them in quantity, let me know, I have some specific changes that need to be made to tank and info regarding off the shelf tank accessories. I've fixed up many TF burbs and panels and, as you can see, have thought allot about tanks.
