700XS (MaximX)

Maximized X

The Maxim X tank is a little on the small side. So when I had to repair a big dent as part of a restoration project anyway, I thought I'd address the size too.

I didn't want to ruin the classic lines of the X tank, so after much debate, I decided to widen it a few inches, leaving the profile intact. The first step was to layout the planned cut with narrow masking tape. Normally used for things like pinstriping, it follows curves quite nicely.
