Got the firewall more or less cleaned up, then decided to tack the lower windshield/skylight bow. A fair amount of fiddly-diddly work -- more or less based on the sketch in the Tailwind forum... lower bow is 3/8" round rube, the balance will be 3/8" square tubing left over from another project -- thought about using 1/2", but that seems like overkill although I may use it for the occasional upright. Then just tigged it up on the flat (several trial fits) -- the stand-off is just less than 4" on the center with 2.5" at the outer edges, so will have to be careful with the center bow so the lexan can form the needed cone -- with careful assembly this should get the windshield laid back about like a Toyota Prius (or the O&O special). Next to clean up the fuselage attach areas.
