I have tried and tried to find mention in the plans for the procedure for countersinking or dimpling the aft spar flange for the lower skin. I called Vans and was told to do it using standard procedures which was to dimple, then countersink to get the required amount of depth to accept the skins. I was also told that the plans don't specify that procedure for the QB, because back in the plans where the other skins are attached in the Philippines, that procedure is specified, and I am supposed to review all that previous work, step by step, as I'm the manufacturer, not some QB'er. I humbly agreed, and went back AGAIN to review the wing plans step by step, and still couldn't find it (it's probably there, I just couldn't find it). Anyway, I don't remember ever using that procedure, dimple then countersink, on this project or the RV8 I built. Reviewing chapter 5, we're told to dimple up to a certain thickness, then beyond that , countersink, just as I remember. Screw it, I'll drill out a QB installed rivet on the inboard skin, and see what they did. Viola, it's countersunk, just as what I'd expect. So that's what I plan on doing to the rest of this .060 spar flange, countersink it. Anyone have any info on this, that I can't find.

Frustrated, but at least not covered in fiberglass dust.
