Sketched out an idea for a metal wing cradle based loosely on an EAA wooden cradle. Gathered supplies, cut and trial fit of Superstrut sections for a wing cradle. Design objective is to hold 2 - 24 (20' wing + 4' spar) foot wings with pnuematic wheels, Straight axle rear with castering front wheels for mobility. Will require welding 4 tee sections to secure spreader pieces. Very cold work environment, 10deg F in hangar. Propane tank was so cold that the propane wouldn't vaporize and light off.
