Tonight, I layed out and cut the radius for the forward, inside corner of the F-757's. I then cut the slot in the right F-721 side rail, deburred and clecoed in-place. The F-757 radius needed to be trimmed as well as the outside portion of the F-721 so it matched the side skins. It turned out well and I will match drill these parts to the longeron and they fit the left side parts.
