After heating a stick in flame heat source (about 15cm is heated at a time). The bow stick is heated very slowly. Till the heat penetrate to the core, and the wood is heated close to the scorching temperature. Bend the stick as the temputure is ok. While the stick cools down, it will hold the camber. Be very carful with the whole process, as it's not good to get the stick over bent or get twisted.
