tunnel paper dolls

I wanted to be sure that I have some clearance from the transmission so I attached some wood to the posterboard as a shim.  Just like putting Bernie's toupee back on.  Cachunk:

A couple cuts and bends.  I expect this to look like crud.  Since this is very thin material ~.050 inch I will have to weld with .024 wire on very low heat.  I can forget about gap filling.  But at the same time it will be impossible to not have gaps.  You can see with the paper that I had to splice in a bunch of pieces.  I hope to keep that to a minimum with the steel, but it is probably going to go that way.
