View Full Version : Arrow spine help

10-16-2008, 05:44 PM
I need to know what spine of arrow to use for a new bow I am getting. I do a bareshaft tune once it is setup and get the spine ecactly correct via. cutting, point weights, and bow lbs. adjustment. However, I need to get an accurate measurement of the spine deflection I need. I'm not looking for an estimated guess, or the closest spine available by a manufacturers list. I'm looking for the actual deflection needed. Is there a program that can compute this that allows free access? If not, is there anyone who can run some numbers for me through such a program? I'm sure there must be one available...
