So with the lower mount/bucket done it was time to do the fuel cell and here is where I started getting nervous.. I only have like 5 hours of Tig under my belt with a high potential of fawking this up.. So of course I started with cardboard and got the front/rear aluminum pieces cut. So its roughly going to be 16 gallons. I did awful in geometry and it was many years ago to try and measure a complex shape so I kinda measured in the central points for a rectangle.
