Both final fill-in pieces that ultimately become the wing saddles are nowfitted and glued. Next up is to cut out the wing sadldes using the supplied ply wing jig which is to be mounted on the main frame sides. Since the fuse sides are curved you have to shim the jig in a vertical ( plumb) position with scrap balsa. I am going to instead make a more substantial jig that will hold the fuse and allow the jig to be plumb without shimming and screwing into the sides of the main frame. Since this is a pretty critical step I think it will be worth the time and energy to do it.
