Hi all:
Actually Doc didn't get it quite right as I don't use, and never did use white glue or Aliphatic resin for joining skins. I did long ago use the "tent peak" method of joining the skins with a masking tape "hinge" and then folding open the gap. I used Ambroid as the adhesive then, not white glue.
I've long since developed new, and I think better, way of sheeting foam core wings. I once put this entire dissertation onto Stunt Hangar, and it should be in the archives somewhere.
I stumbled across a website that has apparently "pirated" that how to. Although that has me a bit miffed, the main thing is to get the information out to those who need it. So, here is the URL to find that complete How-To on not only sheeting foam core wings, but also on how to attach molded leading edge caps to cores that have fully rounded leading edges. So, go here:
