Drilled nut plates for the right wingtip. I had trouble countersinking with the drill - the holes were kind of 3-point in the soft fiberglass. I ended up using the debur tool to hand countersink. That worked fine. I used the pneumatic squeezer to dimple the wing skins. I reattached the tips with a few stainless steel screws.
The left wingtip went faster. Surprise - about 1/2 the time.
