The fact of the matter is that everybody makes strings differently, even if they use the same string jigs and the same brand of string. Notes are essential, of course. But on my notes you will see numbers that are crossed out and replaced by slightly different numbers. And a nail in my archery room with strings that don't quite fit any bow that I have. But if I want to make another string for a bow that I have already made strings for, I can make them fine. And if I want to make a string for a bow that is close, I can come pretty close on the first try.
But if what you want are great strings at the lowest price, you will not make your own strings and will buy them from any of the highly qualified string makers who are our sponsors. Professionally made strings just don't cost that much. And you don't have to wonder why you have a lifetime supply of BCY 10 that is now obsolete.
I enjoy making my own strings, and that's why I do it. If you don't have the desire to do it yourself, you shouldn't.
