Michael, Thank you for a very well thought out answer, and the gracious attitude with which you provided the information. Although we haven't overlapped any on the Piet List, (I've been on it for about a year now), I can tell you're going to be a valuable resource for all of us as time goes by. Get ready for the onslaught! I checked the latest 43-13 (Ch 1, Section 4, par 1-40 for you reg-readers out there)and while splices are fine, it recommended not having a splice beneath a wing attachment fitting. To me, glueing split spar ends back together, with ply plates covering, constitutes a splice - two separate pieces of wood glued together. To me, that was the deciding factor. I intend to use accepted methods practices and parts on my Piet. A shortcut in a critical area like spars could be a shortcut to the ground! They also make a big deal about completely sealing the butt end of the spar to prevent future cracking. The 43-13 recommended using a slow-curing epoxy adhesive or sealer to seal the ends off. I haven't looked at the 43-13 in a while, it's good reading!Gary________________________________________________________________________________Date: Fri, 29 Sep 2000 08:18:27 -0700
