I am working on a maple board bow,and I'm getting close to the tillering process. I understand that one starts with a "long string" and then moves to a string sized to fit the bow length. My first question is when do you stop using the long string and shift to the other string? Should you tiller all the way to the desired draw length with the long string and then go back and start over with the second string? If not, at what point does the change of strings occur?
A second question - is there a good video of the tillering process on line? Thank you.
