Though a wing jig is not required for construction, I've elected to build one to assist in building both of the wings simultaneously. It will also help assure that there is no twist in either wing during drilling and riveting. As such I started sourcing wood and aluminum parts to construct the jig. Due to the nature of the garage, I elected to build a stand alone frame/box which would hold both wings. the frame is primarily constructed of 2x4's and measures 10' long by 5' tall. It uses various sizes of aluminum angle to secure the wing itself to the frame.
