Prepped Aileron Brackets and Gap Seals, Flap Braces; Ran Pitot Tubing
This morning Ron (just starting an RV-9A) come over to get my wing 'jigs', check out the project and shoot the breeze about RV's. Then I finished prepping the aileron brackets for riveting (some of the holes require AN470 rivets so you have to countersink for them).
Then I started working on the aileron gap seals and the flap braces. Above you see the aileron gap seal clecoed to the right wing. After clecoeing I drilled them to the rear spar (and the gap seals to the skin).
Then I deburred and dimpled the gaps seals...
Then the brackets. Here you can sort of see where you have to trim the flap brace. There's just one cut that must be made so that the brace can sit down between the forks in the rear spar doubler.
Then I experimented with how to run the pitot line through the wing. I think this is what I'm going to go with. I'm going to use a bulkhead fitting in the hole where the bushing would normally go. I'll have a 'lead' coming out of the pito that I'll sort of swirl around in there in a 270-degree turn back to the fitting. Got it? Ok, when I can find the correct fitting for the pitot I'll be set.
Then I started gathering everything to install the aileron bellcranks. Anyway, I couldn't find any of the bolts or bushings required for this. I looked and looked. I kept saying to myself, "it can't be in this bag, because this bag contains center section hardware". Well, I went inside, got on-line and went to Doug Reeve's vansairforce.net site. I remembered that he had a link to a spreadsheet of all the parts in the -7A. I downloaded the file, searched it and found that all the hardware *IS* in this bag. Oh well. I'm in idiot sometimes. That was about 45 minutes of wasted time looking for that stuff.
