OK, the good news is that my wing kit arrived today so the building is starting to get serious now.
While waiting for the kit to arrive, I have been studying the plans and thought I was prepared to begin with the tank skin platenuts. Well, maybe not. Looking at those beautiful, golden spars, I want to make sure I don't mess things up so I would like to ask for your all's advice before I get the microstop out.
Here is my plan. First, drill out the rivet holes to #40. I will drill out one of the holes, cleco a platenut to that hole and align the other hole, then drill it out. Next, with a #40 countersinking bit in the microstop, I will countersink those holes to accomodate an AN426AD3 rivet. I will then rivet the platenuts with my squeezer.
I was a bit confused for the next step. In the paper bag along with the platenuts in my kit, there were a bunch of #8 panhead screws, and I was wondering how the heck we are supposed to countersink those! Either I was given the wrong screws, or hidden at the bottom of the bag or somewhere else are the #8 CS screws. So, now that I have figured out I won't have to countersink for a pan head screw (!), once I have the platenuts riveted in, then I will do what the instructions say, which is to countersink the screw hole for a #8 countersink screw.
Hmm, writing it out like this (plus now assuming that CS screws and not panhead screws are used), it all seems pretty clear now. I have viewed most all of the RV-9 sites that Van's links to and I have read how people make jigs to do this, but it seems to me that what Van's recommends will be ok.
Thanks. This wing-building is going to be interesting!
