Two points:1) Rodney, when building a laminated spar or longeron, the grain directions ofthe laminated strips should match. In the case of a spar, the resultant grainshould be horizontal, when the spar is standing upright. In other words, if youlook at the spar installed in the wing, the grain lines should look like avery tall deck of cards (grain lines about 3/4" long). In the case of longerons,since they are usually square, so the orientation isn't an issue. The graindirection of the individual layers should stack on top of each other. and2) Very nice to see a post from Graham Hansen. As always, full of well thoughtout, useful, practical advice, based on personal experience and logic.
