Fitting the W-925B angles

This angle piece has to be positioned to where it is flush with the bottom of the other ribs in the wing. The top of the bracket is easy, it just fits by laying on the inside of the rear spar, AND the top hole has to be countersinked to allow the dimple in the rear spar to go into the countersinked hole in the angle W-925 piece. I drilled this hole first and took the assembly apart to countersink that top hole in the W-925 angle, then put the whole assembly back onto the wing. The problem now is other end, where you need the angle side to be flush with the other ribs. I grabbed a piece of scrap from the scrap sheet pile from the tail kit and cut a slit in it with the band saw and drilled to holes on each side of the scrap piece and clecoed it to the ribs. This gives me a "go-by" for making the W-925B angle fit into the right position. Once I got the holes drilled, I simply removed the scrap piece and use it for the next flap bracket.
