Title: board bow tillering
Post by: Dan Jones on March 09, 2018, 03:26:00 PM

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.

Once the limb tips are coming down about 6 inches, brace the bow to a low brace of about 4 inches. Keep tillering and when the limb tips are coming down to about 9 inches, brace the bow up to 6.5 inches.

Also to start out, do not use a super long string. Put in the string grooves and use a string that just fits the length string groove to string groove.
