Today I dimpled the gap fairings for both wings. The plans are not very detailed, but some common sense seems to be in order, I think I have dimpled the correct sides of the parts.
I also found a couple of steps of didn’t realize I needed to complete. I short row of countersinks in the wings, and the j-channel for the outboard bottom wing skins. The j-channel isn’t drilled, and is supposed to be match drilled using the spar. I’ll need to match drill it against the skin, which should be ok, but would have been easier before I dimpled it.
