Brief Description: Rivet 2 Nutplates on inboard web of spar
I drilled and countersunk the rivet holes for two more nutplates in the inboard web of each spar today. The plan's did not specify the rivet size but this wasn't too hard to figure out - AN426 3-something. I used the Avery rivet gauges to select the right lengh's, -6's in this case. I still don't have a lot of confidence making my own decisions yet so I went online to confirm these sizes in the RV-List archives. Once the rivet holes were countersunk on the aft side of the spars, the forward sides were deburred. The nutplates were just out of reach of the yokes for my squeezer. I had to buck these rivets. David actually helped me since one cleco didn't quite cut it. There was a gap between the spar and the nutplate. The nutplate needed to be clamped tight against the spar but I didn't have a clamp that would reach and still give me room to buck the rivets. David ended up just holding pressure on the nutplate with a small scrap piece of wood while I bucked these rivets. Worked great but I couldn't do this alone.
