I do like the tank behind the seat ... but ... since I'm still in the experimentation stage I decided to build a fiberglass tank for the top bar and see which I like best. I don't know, what do you guys think?
Here's the first piece of foam board defining the basic shape. Next, I'll cut several more just like it and glue them together in a block. Well, two block I guess since it's going to be a saddle tank. Then I'll cut the tank to shape with a sanding block. If I still like the looks of it, I'll lay 'glass and epoxy over it and melt out the foam.
