Two is enough, I'm all done with impregnation. Never did try it with plywood.
Thinking something like this: http://en.wikipedia.org/wiki/File:Fantom2sits.jpg
Only varnish where the burgundy is, and burgundy where the white is, to hide the corner joint fill. I find the trick to making plywood last is to have lots of drain holes in the floor. Standing water is what wrecks it.
4 sheets of $7 plywood. My big splurge was epoxy instead of polyester for the joints. Most of the rest is junk I aquired.
WxHxL= 32"x36"x76" (just fits out the shop door, with front suspension removed.)
Weight of the body without seat or wheel well is 20lb. The swingarm, shocks, hubmotor, tire is 50lbs! Lots of other stuff will add up fast. 6x12Vx12Ah of recussitated gel cells. ...
First attempt at a rain cover will be a large clear umbrella. I might develop it from there, but it will be hard because with two adults you sit with your arms hanging out the sides. Covered velomobiles of this era tend to look ridiculous, and very un-aero.
Did a destructive test of my dropout mounting:
I'm going to cut the corners of the plate to reduce the stress in the plywood where it broke, and do the real layup with epoxy instead of white glue, add an extra layer of plywood. Should be good for 1000lbs, my target.
