My point of contention here is not whether it'll work or not work and in Barry's case for the last 8 inches of the wing spar I'm sure the loads are slight towards the tips and Larry using it in his canopy bows is in a non critical area of the airplane. There are a lot of people looking in at this site to learn how to do composite work and we got complimented as being a very informative source of information. I personally don't think it's a good practice to do in the critical areas of the primary structure and would like point out my views to the builders that are just getting started as we don't want any mishaps happening because of misinformationLarry&Sallie Flesner <[email protected]> wrote: At 09:44 PM 8/24/2006, you wrote: >I'll express an apprehension here about using a layer of >fibereglass cloth in a glue joint.

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.
