Hi Jim... No argument as far as I am concerned, I'm simply following along and posted a couple querries and a comment or two...to whit I am anxiously awaiting hearing a bit of obsceneties from Stephen in clarifacation :):) Why whould anyone would get bent out of shape (if indeed anyone is) ?? I agree with Joe G that there's been a bit of talking past each other... nothing unusual in that.. but beyond that I see no problem brewing here. If E*I can say that a 10 inch long 1/4 inch round shank is stiffer or less stiff then a 3/8 inch wide hex shank of same length and same type of wood then great... I'd just like to know a bit more about how its done. Course this is a generalization, and some closely comparible shanks might break the rule... but just so.
