Three hours of work to put in two bolts and nuts? Yup. There *should* have been a Rivnut underneath the hole so I wouldn't have to worry about it, but that was not the case. Problem with the Quickbuild that I am hoping is resolved for future builders.

I was able to get the bolt through one hole and needed to use a step drill to open up the other hold. For that one, the hole in the bracket and the hole in the rib were both the right size, but they weren't lined up, and since the bolt is just going to hold a spring and not need any kind of alignment, I didn't mind making the bracket hole a little bigger.

Getting the nut up into position so I could tighten the bolt down onto it was an absolutely pain in the...finger. There was barely enough room for that finger, and the elevator torque tube junction (I know there is a better name, and maybe someday I'll come back and edit this to reflect the correct name) got in the way too. I tried a couple of hours of different things to get the nut into place. One idea, since I couldn't pinch the nut in my index finger and thumb like people normally do, was to put some tape on my finger to hold it in place. That didn't work because the tape got stuck on the sides of the ribs. Then inspiration hit, and I taped the nut into the box (closed) end of a wrench. I could smush that into the rib and get it in about the right place to start the bolt into it. Once I was 80% sure the bolt was in it, I wiggled and jiggled the wrench to break it loose from the nut and pulled it out. Then I used the front facing camera of the phone as a bore scope (no, I don't have one of those, but I should!) to make sure the nut was in place. After that, I squished the open end of the wrench in to grab the nut and tightened everything down. That first bolt and nut took about 2 hours.

The other one, without the torque tube in the way, took about half an hour. Learning curve! And, lack of impediments.

I learned some tricks on this one and will be sure to tell my friends to put the Rivnut in the rib BEFORE putting the rib in the plane. It doesn't need to go through the bracket and the rib, just the rib, but it absolutely needs to be there early!
