Haven't done much on this build. I've installed ribs in the jig and sanded the top to shape. It didn't take too long. Just have to be careful. I'll flip the ribs over and sand the bottom. After sanding I'll match these ribs to the ribs for the other wing and sand those down. Ribs then go back in the jig and wing build starts. I made this jig as a 2 part system. One is the table and support blocks. The second is the jig itself. I can flip the jig top to bottom or left to right or just remove it from the table. It has 2 positions for 34” and 46” wing builds.
