Scott It has been my observation that although they don't want to admit getting the knowledge somewhere else, that alot of the metal and fabric guys glean an awful lot of information from the postings here and other glass builders. There are several places on the plane that it just doesn't makesense to make the part any other way than with glass. Canopy frames, engine cowlings, fairings, and such can be made with compound curves with glas routinely, where with other materials takes an artisan, which most are not.
