Tonight was, once again, kind of a boring night.
After getting both ailerons mostly matchdrilled, I have a long road of prep ahead of me.
In about an hour tonight, all I managed to get done was the disassembly of the right aileron, plus some edge-finishing, deburring, and dimpling of the right aileron spar and reinforcement plates. (I started with those, because I can get those prepped, primed, and riveted before diving into more boring deburring. Getting pieces riveted together really re-motivates me…even if it’s just a few rivets.
Got the right aileron disassembled.
After edge finishing ALL OF THE LIGHTENING HOLES….jeesh, I looked through the manual and all over the plans for any clue on whether to countersink or dimple the aileron spar.
All I could find was something that said, “disassemble, deburr, dimple, and prime the components. Oh, and countersink the counterbalance pipe.”
So, it SOUNDS like dimpling the other parts are correct. What about the internet? Not much help there. Thanks a lot, Google.
Anyway, I gave the dimpling a shot on one of the #30 holes on the bottom of the spar, and stuck a CSP-4 (is that the rivet number?) in there. Looks pretty good to me. What do you think?
Looks good from here.
So, carefully watching for any flange distortion (there wasn’t any), I dimpled the bottom flange with a #30 dimple die and dimpled the top flange with a #40.
All done for the night.
That was about an hour, and while I could have started on the other one, I decided to pay a little attention to my family.
Puppies, here I come!
