I'm a newbie, so I'm not real familiar with the Tele, but why not just steal the method other manufacturers use? Install a hardwood block in the fuse at the center of the leading edge. Drill a quarter inch hole for a dowel to slide into. Install a quarter inch dowel in the leading edge of the wing, making sure that it's anchored to something solid (a forward spar perhaps?). On the trailing edge, install a hardwood bolt plate in the fuse and plywood (3/16") on the top of the trailing edge. Place the wing on the fuse, making sure of proper alignment, and drill the bolt holes throough the wing and bolt plate using a 3/16" bit. Enlarge the holes in the wing ONLY to 1/4". Tap the holes in the bolt plate, apply several drops of CA to the holes and after it has cured fully, retap. (I wish there was a blindnut that could replace this method)
