Elevator

Put the horizontal stabilizer issues aside and concentrated on the elevator assembly yesterday. Rib assembly is built and cleco'd. Tips are drilled but need to do some sizing on the hinge pins. Got the rear channel assembly built and installed. Should finish elevator next weekend. Will then resume work on the stabilizer. Looks like I'll be able to use A5 rivets where I have had some rivet removal damage, thus saving me from having to purchase a new stabilizer skin!

When I tried to pull the skin over the gussets, I realized I was in trouble. There is no way I can do it. I will try drilling out the rivets and salvage what I can, but my first attempts resulted in…
