RE: The Scratch Plane featured in Fly Rc
Here are some pictures from a week or so ago that show how I glued to two wing halfs together. I used two 1/4 inch pieces of wood under the outer ribs, then used a big clamp that I built from a home depot yard stick. I put packing tape on the underneath of the wing halves before putting the epoxy on. I then put packing tape over the top of the wing and put a one-by-four on top of the whole thing to keep pressure on it while it dried. The result was good. I also put the nylon bolt through the wing into two pieces of 1/4 ply. I used a metal bolt of the same size with a notch in it to cut the thread and then ran thin-CA down the thread of the metal bolt and screwed it in and out to make the thread hard. Once I got the wing on with the dowel and the bolt there was small (1/16) gap under the wing. I guess this is due to the dihedral. Anyway, the last picture shows how I glued some 1/16 sheeting on to 'fill' this gap.
