The only thing missing from having Betty 100% converted to run on vegetable oil is a real tank. Against the criticism of many, I wanted to build my own custom tank, out of fiberglass. I’ve always wanted to learn how to “make stuff” out of fiberglass, and I figured this would be a good way to teach myself how. The smart-asses telling me I shouldn’t do it just made me want to do it more.
I wanted the tank to use the odd-shaped area behind the wheel in the trunk. As I started building my form, I realized I better put some thought into how I’m going to remove the tank, because I’m sure there will be a time when removal will be required. That little detail made the tank size shrink quite a bit. I had to sacrifice area for wiggle room. This is a wedge I made that should give me enough clearance when finished to let me remove it. I used a 10-second two-part glue that worked great.
Here is the same piece in the trunk.
This is the form that provides a surface to build the tank walls not touching sheet metal. I’m using the sheet metal surfaces themselves for my form where I can. This stupid box took me about 6 hours to build. What a pain! I’ll have to destroy the box when I remove it from the fiberglass.
So far, my fiberglassing skills have turned out to be on par with my welding skills. Not too good!
