Well the standard length for shafts is 28 inches, so most commercial spine testers are set up at 28 inches. If you shoot a 31 inch arrow though, your spine you get on your spine tester will actually be 15 pounds heavy because of the extra flexibility the longer shaft gives you. (5 pounds an inch) If you shoot 31 inch shafts then I would set it up at 31 inches. If you are making shorter shafts then I would set it up at the actual length so you can get the most accurate spine reading that you can. This is just me though, other people may like to stick to the standard 28.

I have been contemplating this since I saw that site with the 26" spine tester. I think I would change it to 28 if its not to much work. Even a 26 inch draw would have a 28 inch arrow because you dont want to draw a broadhead to the back of the bow. Its probably not a huge deal on parallel shafting but if you get into tapered or barrel shafts the center will be stronger than the end. So the more shaft you get between the posts the better. Justin
Bow Bandit:
how would i convert the spine tester to the 28 inch ...because there is a whole chart i would have to do so would i switch the 26 to 28 (or what ever length) in the equation to get the proper delfection for the right spine???

A spine tester is set up for 28". If your arrow is 31" it will still spine the same but when you shoot the arrow it will shoot like an arrow with 15# lighter spine. the extra length( 3") will reduce the arrow spine by 5# per inch over 28". At 31", it in still spineing between the 2 post set at 28" apart.
Now, I'll bet you are really confused!!! LOL Pat
