Finally got the spars spot primed. Used Alumiprep to clean the countersink cuts, then applied alodine. I started with a qtip, but ended up using a small bit of sponge to soak up the alodine and then dab the cuts. This allows quickly soaking every cut, going back over several times for a few minutes to keep fresh alodine on them. Worked like a charm. Did both spars in .9 hrs.
Used about a centimeter of alodine from the top of the quart bottle. The bottle should last for 2 or 3 more airplanes.
After the alodine priming, the countersinks are almost the same color as the spar.
Took a break for dinner, and then the spars were dry and ready to go. But first, riveted platenuts to the tie down bars. It almost goes without saying, the squeezer was used for all of the rivets.
After the tie down bars, started on the spar platenuts. Got about half of one spar done before the hobbs hit 2hrs and time to stop. Only had to drill out one (because the rivet missed the platenut. Doh!).
Spar 9-1437-R, with platenuts installed.It sure is nice to rivet after that long layoff. Real progress is riveting.
