Douwe; as to your question about anyone else building wooden airplanes besidesus, the only other group I'm familiar with are the KR builders. The KR uses awood structure with foam infill and fiberglass skin. It also uses wood sparsand other framing members. The discussions on the KRNet are quite similar toours, with T88 predomindating but various other adhesives being used for thewooden parts. West Systems seems to be mentioned frequently.I, too, wonder about Titebond III. It is an excellent adhesive, proven and testedwaterproof, and if I understand the product literature correctly it has ashear strength of 4000 psi at room temperature, vs the listed shear strength forT88 of 2500 psi at 67F. They both lose strength at elevated temperatures (150For so). Still, as Clif pointed out, the glue strength is at least as goodas the wood strength at those temperatures. There are many benefits to usingTitebond... it's a one-part adhesive that works well at most shop temperatures,is widely available (I've never seen T88 in a hardware store, but I see TitebondII and III in most such stores), dries clear, and is easy to clean up.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: New Builder of the Pietenpol
