I had read from multiple sources that wood was better for bow-making when dried to 7-10% moisture level. Although kiln-dried wood dries to around 7%, it's done rapidly, making the wood brittle and unfit for making bows with. My idea was that 7% moisture content, kiln-dried or not, was ideal. Well, I eventually broke that bow trying to make an arrow rest in it. Later that same day, my dad and I went to the library. I pulled out the only book on the subject and started reading. There it was, plain as day...
. . . if someone tries to convince you to use kiln dried wood for a bow, you should wave your arms and make horrible faces. If that doesn't scare him off, be prepared to run for your life. Kiln dried wood is brittle and will NOT make a bow . . . Bows & Arrows of the Native Americans by Jim Hamm
Also, I've gotten a resource page up now where you can find videos, articles, and books I've read. I'm going to be updating it periodically as I go, so check it out!
