My recent winter break from school actually gave me a chance to start my new tank. It is still in the early stages, but I will post any and all progress that I can.
the idea was to stretch the tank length and add some volume. I'm not sure how much volume has been added yet, but I know it will be more than the tank tank can hold. I struggled between fiberglass and metal, and I went with metal for the sole reason of safety. Fiberglass cranks and splinters, metal will crush or bend first. Most likely to be made of steel, but aluminum would be nice too.
I tried many approaches at this, but found the best way would be to make a fake tank first (outof cardboard) where I could determine the shapes/sizes of metal that I would need. I kept all the seams rather simple, but when done in metal they will be more rounded. I needed to plan it with the thought in mind that every piece would be cut from a flat sheet and the least amount of bending would be ideal.
I'm cramped for space, so please bare with the tight/akward photos...
Here is the tank mockup mounted on my frame. It is still missing a large frontal panel, but I hope you can get the idea.
