Started on the rear spars today. My son Anton is home on leave from the Army for two weeks so put him to work as you can see below. First off was to deburr the edges of rear spar, the reinforcement fork and three doubler plates. The doubler plates are then clamped onto the spar and the holes match drilled and cleco'd onto the spar as you can see in photo #3.
