There was a ton of prep left to do here. Ended up going back to the Epoxy primer (AZK0) for the bottom and fwd skins and the stiffners and miscellaneous parts. There's a lot of back riveting done on this section and getting the seat ribs aligned, squared and parallel took some time and care. This is not something I would have been able to do alone. The skins are so bulky that I had to ask my mentor Ted to come and help me the last couple days. I also used some Bonderite alodine to cover the surface of the anodized bulkheads that were countersunk. This was expensive ($100) to purchase but it gave me piece of mind. Additionally I back riveted the nut plates for the gear brace. I used the step drill on several occasions. Little but if reaming and a little bit of match drilling. Don't forget to “whang” the gear braces in the vice (per section 5 instructions—they literally say to hit it with a hammer in a vice until it's straight). Lastly I had to grind down 40 rivets from AN426-4-5 to 4-4.5 because they didn't come in my kit. Perhaps consider purchasing m 4.5's to save yourself the hassle. Now we just have about 500 rivets to set in the morning :) Couple days away from have this section complete!
