Here's some bowmaking books I've read:
All three volumes of Traditional Bowyers Bible.
Hunting the Osage Bow by Dean Torges
Billets to Bows by Glenn St Charles
Bows and Arrows of the Native Americans by Jim Hamm
A couple of helpful websites:
The Ferret
George Tsoukalas
And a lot lot of good bow building links on the instruction page at
Women Outdoors
And if you make your own bow, you might as well know how to make your own string so...
Flemish String Instructions
Have fun!
