I'm one of those do it yourself guys and made my own bow press a couple of months ago but i have one question. What is the correct twist ratio between the cables and the string? I kind of guess at it and get close but was wondering if there is some sort of standard. I've never seen anyone change strings before so I came up with my own process after doing some research. This is the current process I use when changing my string. Please tell me if I am missing something. I put the new strings and cableson so the ATA length is correct. I try to get close to the ATA by twisting the cables first and then I twist the string untill the ATA changes then I back of a twist or two to try to balance the load. I then check for proper cam timing on my dually, tiller,cam lean, and creep tune to get perfect roll over. Just curious how the pro's do it.
