I guess I was confused about what Rodney was actually saying.  First, I was taken aback by the cutting remarks he made towards CrateCruncher!  Then, I belived he was saying the shear web was to have it's grain run parallel to the spars.  He actually stated having the grain on diagonel and to use plywood.  I have no problem with this and agree it's likely the strongest.  If the airplane can handle the extra weight of plywood shear webs, have at 'er.  However, I think vertical balsa works well where the lightness is needed. </p>

I am amazed at times, how these threads can become so hostile!  I don't understand this. </p>
