Rear spar

I started with the rear spar by deburring the edges of W-707A, E and F, then trimming and deburring W-707G&D. Then I clamped and drilled the W-707E&F to the rear spar (W-707A) and cut the hole for the aileron pushrods in the W-707E's. Next, I clecoed the W-707G&D's to the spar and match drilled all of the holes. I also drilled some of the W-707A holes above the W-707G's to allow dimpling after deburring everything. I machine countersunk the four holes on the ends of the W-707F's, then I disassembled everything and deburred all of the holes and dimpled the ones mentioned before. Then I cleaned and primed all of the parts.
