I am looking at using a rachet bow press to be able to do my own tuning and fixing. I am wondering if there is any good how to books out there that explain how to correctly do all aspects of bow maintnence? I don't have a pro shop close that I can get to often and I really don't know how to do any of the stuff correctly but want to learn. It is tuff when you don't have anyone to learn from. I need books or authors to lookup from basic to in depth. Thanks..
