OK, here we go.. the "Tank" design...
As always I started designing the tank on a piece of paper. The actual design is assembled of some trike pic's I've seen on the net. Then I had to adapt my design to the actual 'hardware', my trike. So out to the garage I go and take some measurements. 
What you need: a big cardboard box or two, a utility knife, packing tape. Start with the top part, it's easiest. After a lot of cutting and taping it was done! My cardboard tank is finished. Hopefully it does not rain now! I sprayed it black that will do...yeah right...
I don't have any pictures of me cutting all the pieces. But basically you take the cardboard tank apart again, lay the pieces on a sheet of metal, transfer the outline and start cutting. I got the metal from the body shop (thanks Jeff) for free. He also lent me the air driven metal shear. Beats cutting it by hand and you'll end up with a nicer cut.
All welding on the tank is done with a no gas Mig welder. Five minutes grinding, some body filler, a coat of primer and the tank is ready to be painted and airbrushed. Don't forget to cut the holes for the am/fm cassette player or you'll be sorry later. Best is to get the player and transfer the hole sizes onto the metal.
Here you see my real tank (under the seat (Semi Truck brake tank)) and the front metal panel (under the fake tank). The real tank is bolted onto the frame, the panel is welded. The rear body panel, made with extra blood, sweat and tears! Again, a cardboard template was made first. Cutting torch to heat the metal (sweat), 2x4 clamped to the work bench to bend the metal (blood) and a grinder to smoothen the edges (tears).
