There seem to be two types of material to bond in an Air Camper: solidwood (spruce, fir, etc.) and plywood (birch, mahogany, etc.) I agreewith Steve that for solid wood joints the final prep of the piecesshould be with a sharp tool, not sandpaper. For the plywood gussets,however, it is recommended to scuff the plywood surface just prior tobonding. I've used 220 grit on birch plywood rib gussets with Weldwoodadhesive and gotten good results, including a ten year old rib built inFlorida with gussets still good and tight. If you have never used ahand plane, they are great once you get used to them.Mike List________________________________________________________________________________
