My top and backbore are stuck together. What do I do? Print
Don't even think about pliers!

In almost every case an aggressive "whack" will do the trick. Grasp the mouthpiece firmly with the rim facing up. Use a rawhide mallet or wooden clave to strike the top surface of the rim. If these are not handy, use a scrap piece of wood or a wooden hammer handle. The wood cannot dent the solid brass, so be sure and strike hard. In most cases the components will now unscrew easily by hand, but may occasionally need some additional gripping power. The best I have found for this task are rubber tourniquet strips. Lid grippers are also okay. We have not found any wax or grease than can guarantee to prevent your parts from sticking together. The best way to avoid a problem is to unscrew them regularly.
