Completed the ribs for the vertical tail. Found that the 3/16 part for the v-tail forward spar has too large of a bend radius. It won't sit flat on the spar channel, and since there are clips on both sides of it right at the end (where the radius interferes) for the inner forward rib and lower main rib, I can't just fudge it or shim it. I'll order more 3/16" and make it over. I'll have to modify the metal bending box to be wider to allow for this part. It's too wide for my current bending box. (this turns out to be a $25 mistake to get a 1'x1'x.190" plate).
