Completed the following tasks on the Rear Spar Components: * Mark and cut out the holes for the aileron pushrods. You can use a Unibit to remove a major portion of the area, and then use a round file or a rotary cutter in a die grinder to remove the remaining portion. Carefully smooth and deburr the inside of the holes.
* Cleco the W-707G reinforcement fork and the W-707D rear spar doubler plate to the W-707A spar channel and drill the rivet holes to full size. Note: this part bends during punching and can be straightened easily by hand. Still have some minor bending to do to perfectly flatten the W-707G reinforcement forks.
* Deburr, prime and prepare the rear spar components for riveting. Note that some of the holes in the W-707F are machine countersunk for flush rivets (DWG 10A, Detail A). Still have to prime these parts.
* Once the reinforcement fork is riveted to the spar, it is difficult to dimple some of the holes in the upper flange of the spar. On the inboard top flange, for the length of the W-707G, drill the holes for the main wing skin to final size (#40) and dimple them before attaching W-707G.
