Riveted HS main and front spars, and VS main spar. My plan was to use my pneumatic squeezer for most of these rivets, but for some reason it does not want to squeeze #4 rivets. No real problems with these assemblies, other than having to shoot and buck one rivet on each of the two VS-410 rudder hinge bracket. The center rivet closest to the inside radius on each of the brackets were too close to the radius for the squeezer to reach adequately. Also, I needed to more deeply countersink for the flush bottom rivets holding the spar channel and doubler together. On the first one, I had the countersink cage misadjusted and went too deep. I'm pretty sure I can just use a #5 rivet here, I just need to find one.
