One thing I would like to have is a
Maslow CNC router*. It will accommotate 4x8 sheets of plywood.
This VW station wagon conversion uses compound curved wood joinery. The same shape could be created by laminating 1/8-1/4" plywood cutouts.
That would require finger-jointing two pieces together for each side. But it could be reduced down to an aerocap that clips on like a Jim Dandy luggare rack.
Unlike the rack (or wagon) it would taper in plan, the seam across the roof under a vinyl top.
edit: Cooling could be a row of dimpled died holes down the front of the [skirted] rear fender, pressurizing the rear wheelwell that feeds a Type III fan intake.
* Maslow4 Kit $525.00 -- SOLD OUT
2nd edit: I guess I'm back to where I was in 2012, so I've had the Superbeetle longer than any other so far.
Weird. My Imgur account is gone but the picture still posts. Just the opposite to Photobucket.
