This image archive covers almost every part of a stonebow. Just follow the links in the list below to access the picture described by the link.
For more information on stonebows, I would recommend the following books: A Guide to the Crossbow by W.F. Paterson, and The Book of the Crossbow by Ralph Payne-Gallwey. The Paterson book has some good historical information, but for an abundance of technical information, the Payne-Gallwey book has no equal that I have found. In the later are excellent schematics and drawings of every aspect of the stonebow, along with descriptions of how to make each part of the stonebow.
