roknjs-
Go to the "how To" forum and go to a post "Straightening wood shafts....The easy way" posted by Guru on 3/3/06. That should get you straightened out. (pun intended)
I built a spine tester from some instructions on the web. I down loaded and printed the spine scale. I used a couple of pieces of scrap oak flooring (just had it laying around), gas welding rod, some wood glue and a homemade 2# lead fishing weight. It actually works pretty well.
I think you could do a google search for arrow spine chart and find the scale. I found, but can't remember where.
Good luck with it.
