anyone know of any good books that teach you how to set up, tune and work on bows? i've always taken my bows to pro shops to get worked on (new strings put on, peep sights changed, D-loop change, etc.), now i'm kind of thinking about doing my own work. however i have never so much as done a serving or anything other than bolt on accessories. so is there any good books out there that teach you step by step with good illustrations?
