ABSTRACT:
A model aircraft wing construction jig comprises an elongate front assembly rail, a wing rib carrier rod, and a pair of end clamp members which all assemble together to form a jig structure wherein the front assembly rail and wing rib carrier rod extend, in adjustable spaced-apart relationship, between the end clamp members. The front assembly rail has longitudinally-extending jaws to hold therebetween a flat strip of wood with one longitudinal edge portion of said strip forming a tongue protruding from one side of the assembly rail to engage notches in the leading end edges of the wing rib components threadably mounted on the wing rib carrier rod which inserts through accurately located holes preformed in the body of said rib components.
