Hi all,
First I would like to thank all who have posted here, I've been lurking for quite some time and enjoy the wisdom in these posts.
I have been throwing the idea around about making some cheap stump shooting arrows with wooden dowels. I am in the process of building a spine tester and have a couple of questions.
First there seems to be some controversy if a spine tester should be set to 26 or 28 inches and will the 2 inches make a dramatic difference?
Secondly if the grain of the arrow runs perpendicular to the riser should the shafts be set that way in the tester? or will shafts read differently in the tester depending on how the grain of the arrow sits in the tester.

Hope my question makes some sense.
Thanks Bill
