RE: Rodger Dodger Build
A neat trick that I figured out a few years ago for installing blind nuts is to enlarge the hole enough so that the threaded part fits without too much pressure, add several different sized washers to a bolt to distribute the load, and tighten down the bolt so the little "teeth" on the blind nut are drawn down into the wood. Not sure how everyone else does it, but from some I've seen, they use everything from a hammer, hydraulic press, or who-knows what to get them in - and it shows. [:'(]
Once those were in, I added a drop or two of thin CA to hold the blind nuts, being careful not to get it in the threaded part. Plugged in the wing, and used 4-40 nylon bolts to tighten down the wing. Got a nice tight fit between the wing and fuselage(after just a little sanding with some 220 grit).
