Yew will not bend as far as osage. Make the working area of the limb long, ELB's work the entire length. Leave the tips a little bulkier than with osage, it is light but not as strong. Took me four spectacular explosions to learn these differences before I got a bow I liked from yew. Try to do most of the work with cutting tools like spokeshave and scraper. When you rasp or sand, make sure you are not breathing the dust - they use an extract for chemotherapy, very toxic stuff. As the Ferret said, "Osage dust makes me feel like I have a cold, yew dust makes me feel like I'm dying!"
