Used two 4' lengths of 4" dia. PVC pipe as a pivot point for outboard end of wings. Wrapped PVC tape around the pipe in two places, creating a notch for the rib web and preventing the pipe from sliding in our out. Capped the end of the pipe, levelled the wing and built a pipe saddle onto the top of a sawhorse. The caps will prevent the pipe from sliding off the saddle.
