I would be interested in knowing the strength values of wood struts also. Theywould seem to be relatively inexpensive and fairly easy to make. What woodtype should be used to laminate with the plywood center? Ash? Spruce?I would have to be confident that the struts are strong enough, since my butt isgoing to be hanging from them!________________________________________________________________________________

HelloIf you stop to think about it, wood is strong enough for wing spars,fuselage and prop, why wouldn=92t wood be strong enough for struts? T=he way Iunderstand it, the wing wires carry the flight loads and the struts h=old thewings up while on the ground, that is if you attach the wires to thefuselage per the plans and not the struts themselves.Mike Madrid-----Original Message-----=46rom: Conrad, Bart D Date: Wednesday, June 09, 1999 2:02 PMSubject: Pietenpol-List: WOOD STRUTS>I would be interested in knowing the strength values of wood strutsalso.They would seem to be relatively inexpensive and fairly easy to make=.

It could prob give me a rough idea ofhow many tons it would take for it to fail. I imagine it would probablyfail near one of the fittings. Maybe someone has access to hydraulicsbut I don't. Anyone else?Dannymac________________________________________________________________________________
