Decided to try the angle aluminum approach to closing the trailing edge. Seemed to work well. I drilled every other hole for clecos and the other holes for the squeezer. Had to cut down the angle about 1/4 inch to make room for the longeron yoke on the squeezer. The pnuematic squeezer has proven to be a valuable tool. Only thing left will be to attach pieces to it including the counterweights, bolts and trim tab.
