Thanks guys! The jig was actually very easy to construct. Here's how I did it.
I went into my spare styrene box and found a nice thick, flat piece to make the square base to attach the wing supports. Everything came from spare styrene or round styrene stock.....
I checked the stagger from a bottom view of the datafile drawing................
Then I drew the fuselage and top and bottom wing lines on the base with a pencil........................
I lined the bottom wing and fuselage up with the pencil marks and put 4 pieces of round styrene at mid and front fuselage so the fuselage couldn't move around while I was working on the wings. Then I placed 4 pieces of round styrene along the lower wing leading edge and straightened them with a metal ruler..........
I cut some pieces for the upper wing supports from my spares and made the correct 90 degree angles........
A longer piece of round stock is glued to the upper wing support to hold the top wing, nothing fancy.
I used a piece of spare styrene and marked the leading and trailing edges of the top wing from the scale drawings with a pencil and adjusted the upper wing supports as the glue dried................
I checked everything when it was about dry to make any minor adjustments but that was about it.
I think it took about 3 to 5 minutes to complete. Very low tech.
