ProfLooney, thanks for the great tip. I have just put AutoCAD on my computer and it is very handy for lots of modeling stuff but I had not considered it as a measuring tool for laying out panel lines.

Charlie, I am trying to put together a little article on the basics of vac forming, including building your own machine. The actual vac forming is the easy part, making the plugs is where the work is. I have attached a pic of another part for my current project. The picture shows a stock Sullivan wheel on the right and the enhanced version on the left. Regards, Chad.
