Thks Chuck,

I had a good conversation with the owner of Bluejay. He basically said that nothing special is needed for a jig. His suggestion was simply support 1/4" x 36" rods with 3 pieces of "same height" material and make sure that the rods are secured to the supports so that they don't move around. I have a bunch of "manufactured" trim molding that is rectangular (approx. 5/8" x 4"). I was thinking of taking some aluminum strips (cut up pop cans), wrap the strips around the rod (like an omega character - flat on the bottom) and then attach them to the top of the supports with screws securing the rods in place.

I'm trying to fabricate templates for the 1/8" plywood doublers for installation of the landing gear using the tail-dragger approach.

These instructions are kinda like giving a blood hound a scent and expect the darn dog to search out a pile of drugs hidden by the bad guys. I've built 6 planes in the last year and a half, all SIG products. I guess that I'm just spoiled.
