Upsized the holes in the ribs for conduits and did a final deburr pass through everything. Relieved the aileron torque tube angle for the conduit hole as suggested in the plans.
Double checked the correct position and orientation of all ribs and marked their numbers. Prepped and primed the ribs in batches to try to maintain the order.
Assembled and riveted the flap hinge brackets and some of the aileron torque tube bracket. Missing bearings so just cleco'd for now. I'm glad I did too, because it would have been very hard to rivet the rib to the spar.
Cleco'd all the ribs to the spar and proceeded to rivet. That was very difficult and I had to drill out many rivets because the gun would jump and put a crease. I finally remembered that a little masking tape over the set would keep it from jumping. Got all of the spar rivets done and called it a day. A very long day.
Finished up Sunday morning by installing and torquing all the bolts. Additional QC of rivets revealed several more to drill out and replace. Ended up wallowing out one rivet hole in the spar web. Opted to upsize and replace with an AN3 bolt.
4/5 update: back-ordered torque tube bearings arrived so was able to rivet torque tube bracket together and rivet assembly ronin board rib.
