Finished fabricating “V-block” jig for elevators. We experienced lots of broken wood screws until we changed to good quality hardware. We fastened blocks to 4-foot pressboard base instead of tabletop, for portability, and clamped the jig baseboard to a tabletop. Then we mounted the skin-bending jig to a worktable. The jig wood has warped slightly over the past couple of months, but the warp is uniform and should not affect the results at all. I bent the skin, inserted it into jig, and clecoed the skeleton inside to check its initial alignment. The bend came out very nice. I'll have to squeeze the flanges of the end ribs to prevent bulging of the skin on the ends, though.
Bending the R elevator skin. Note the wooden dowel used to maintain a constant-radius trailing edge.
