Fluted the outboard seat and baggage ribs to mach the curve of the bottom skin. Riveted nut plates to the seat ribs.
Bolted and riveted the seat ribs to the bulkhead assembly.
Riveted the seatbelt lugs and routing angles to the baggage ribs.
Riveted the aft bulkhead to the seat rib assembly. Drilled and riveted the doubler to the bulkhead. Fabricated and riveted together the idler bearing assembly and riveted to the bulkhead.
Clecoed the bottom skins together and match drilled some holes. Cut the landing gear leg openings in the forward skins. Machine countersunk the doublers and dimpled the skin stiffeners. Drilled the 9/16″ hole in the skin with a step drill. This hole will be used to mount the transponder antenna.
Deburred all the HS ribs with 400 grit sand paper. Sand paper seemed like the most straightforward approach because of all the segments in the flanges. I was able to get in between the segments with it.
I fluted the ribs and modified the two nose ribs and two inspar ribs per the plans and marked them.
I drilled the inboard nose and inspar ribs to the forward spar. Then I deburred all the holes in all the ribs and then dimpled all the ones that mate up to the skins. So. Many. Holes. I can’t even imagine what the wings are going to be like.
I also created a template to make cradles to hold the HS when assembling. I’ll scrounge some plywood to cut them from and some sort of square stock for the bases.
I didn’t get to shoot primer on the practice project today. I had to work and then brine the turkey for thanksgiving. There wasn’t enough daylight left after all of that. So instead we decided to actually start work on the airplane this evening. I’ll spray primer on the practice project and the vertical stabilizer all together this weekend.
