I work on my own bow all the time. I bought a Bowmaster pocket press for $50. I changed my string, installed a peep, string loop. Set up a new drop away rest and new sights instead of dropping $800 on a new bow. This stuff is relatively easy to do. Everything is on Youtube. I think a lot of people think these kind of things are too complicated and have to be done by a professional. I always like to fix things on my own if something breaks during the season I like to be able to take care of it instead of waiting for a shop to get time.
