Applied properly heat is a great tool for bow making, and I have used it for other applications. Example... I bought a vintage 83 Kramer bass from a guy in church that was stored in a basement, and the neck had a bad warp in it . I loosened the truss rod, built a jig, and heat treated the rock maple neck with a heat gun,and got the neck to go back to were it needed to be. Set the neck back up to suit me, and ended up making it one of my favorite bass guitars.
