Finished deburring the right and left skin edges. Cleaned all the right and left Elevator parts with MEK in preperation for priming. Primed all the parts with Sherwin-Williams P60G wash primer. Began work on the the right Elevator... riveted the two E-910 reimforcement plates and the two nutplates to the spar. Riveted the inboard rib to the spar. Attached the Wd-605 to the spar and rib and match-drilled the holes. Deburred the holes and riveted the Wd-605 to the spar assembly. Riveted the E-903 and E-904 ribs together and then riveted the counter-balance skin to the ribs. Next step is to rivet the stiffeners to the upper Elevator skin.
