Completed deburring of rivet holes and edges on rear spars, doublers and reinforcement plates. Cut aileron pushrod holes in reinforcement plates by drilling two 5/8" holes at ends of opening using a uni-bit, then used a Dremel tool with cut-off wheel and grinding wheel to complete. Clecoed spar doubler and reinforcement plates to spars inserting clecos in all holes which are riveted later when attaching other parts. Set up pneumatic squeezer for rivet size and experimented with spar positioning to make riveting most comfortable. Found that spar place horizontally with edge just off table was good. Set a few rivets before calling it a day.
