Continued Work on Rear Spar

I clecoed all of the reinforcing plates and doubler plates onto the spar and match drilled them to the spar.



Here are the center reinforcement plates match drilled.  I hadn't noticed the missing hole when I took this shot (can you spot it).



The reinforcing plates have to have an odd shaped hole for the aileron push rod to go through.  This hole is already punched in the spar, but must be cut in the reinforcing plate.  I used a unibit to rough cut close to the line and then files and sanded until they matched.



Afterward, I prepped and primed the reinforcing plates and doublers and riveted them to the spars.  Look carefully at the rivet callouts.  There are many rivets that are skipped and several different rivet lengths.



Here is the center reinforcing plate.  All of the missing rivets will be installed later in conjunction with other components.
