willie:
interesting read

the physics presented about vibration and dampening seem right, but I don't know if his actual test method will yield pertinent results for arrow evaluation

 clamping the arrow at one end might be a different situation than an arrow in free flight that would flex at its "nodes"

see           
--- Code: ---http://www.bow-international.com/features/technique/flex-in-free-flight/
--- End code ---

when considering a single taper bamboo arrow, I wonder if you would consider the possibility of changing the weight distribution along the arrow to make it "tune" different? add external weights along the shaft for testing? and maybe add inject? internal weight on the finished models

coming up with a way to evaluate the vibes in a free flying shaft would be the challenge
also, if there is a rotation of the flexing arrow, vibrations can be affected and possibly dampened to an advantage?
