I don't expect my canopy or turtledeck bows to ever have any "peel" loads applied. Also, what changes in a glue joint from a single layer of glass to wood (wing skins to spar) and multiple layers of glass to wood ( wood-glass-wood-glass-wood-glass,etc.) ? I think I left enough epoxy in the glass layers to get a good bond to the wood, through the glass, and to the next layer of wood. I really don't expect my "bows" to fail in any kind of incident that would be otherwise survivable. I'm not concerned enough to test my installed bows to failure or build a test bow to test. However, do not view my installation as a "commonly accepted building practice". I have no personal knowledge of this type of component being tested, other than by my flight time. Larry Flesner
