Pietenpol-List: Grain of wood

I talked to a local shop teacher just the other day about the same thing.He said it didn't make a difference which way the grain (end grain) went.What did make a difference he said was if the grain ended abruptly throughthe length of the piece. In other words, you should be able to follow agrain all the way through the length of a piece from one end to the other.If you have "aircraft grade" wood this should not be a problem. In my caseall was OK.That being said, I laid my longerons with the end grain horizontal to theground. In my thinking this allows the wood to flex in the "up/down"direction when the tail hits the ground verses laying them cross grain whichin my opinion would disipate the energy to one constant and specific pointsomewhere along the longeron. A microscopic issue to be sure, consideringthe side trusses disipate the energy by design, but I think a valid pointnonetheless.StacyThere is only one greater thing than to believe in the impossible...and thatis to achieve it -- Stacy Clark________________________________________________________________________________Date: Sat, 28 Aug 2004 08:54:36 -0700 (PDT)
