In an effort to keep the trailing edge of the wing skin as straight as possible along the top of the wing I used an iron bar and back-riveted the pocket covers to the top trailing edge of the wing skin against the bar, which turned out nice. I intended to do the same along the bottom of the wing and I drilled all the rivet holes in the skin and pocket covers.
However, it seems I made a rookie mistake in doing so because now I cannot fully access the rivet holes with a squeezer or even with my bucking bar. This is because the angle is acute between the pocket and the bottom wing skin I see two solutions available to me:
1. Use NAS1097 â€skin†or “oops†rivets countersunk into the skin which will avoid the need to get a squeezer in to dimple. Then get a short bucking bar with a 30 degree angle on the end which will tuck fully into the pocket and hopefully allow me to buck the rivets
2. Use 3/32 pop rivets, which will be easy but will leave a row of little bumps in front of the aileron on the bottom of the wing. I also have ccc-32 flush pop rivets, but since I can’t get a squeezer in to dimple, I don’t think they would work.
Since I have to finish this and I still have one more wing to go, I’m wondering how others worked around this issue? I made matters worse by not drilling and dimpling before assembly (in afford to keep things straight) and by placing my rivets almost 3/8†back from the edge to allow for trimming later if desired.
