Things You'll Need
Instructions
Use a long piece of pine board, 10 feet tall by 3/4 inches thick by 5 1/2 inches wide, to make the main part of the striker. Cut it down to a width of 3 1/2 inches, and use the narrow piece you cut off to add support by screwing it into the back of the striker. About halfway down, screw on two more narrow boards, which will jut out diagonally behind the striker for even more support.
Shellac the striker. When it is dried, paint the numbers onto the length of the striker. Apply a coat of varnish.
Attach the brass wire using corner braces, and adjust its tension with eye screws at the top and bottom of the striker.
Make your counter. This is the part of the striker that measures your score. Make a wooden spool by drilling a hole vertically through the center of a wooden cylinder. The hole should be just slightly larger than the diameter of the brass wire.
Attach a metal bell or gong to the top of the striker by using a threaded bolt. When the striker is hit hard enough, the counter will hit the gong.
Create the base of your striker with a board measuring 12 inches wide and 2 1/2 feet long. Screw two blocks onto either side of the base, and place a narrow beam between them.
Create the striking arm using a strong, narrow piece of wood balanced on the crossbeam from the previous step. Cut a notch on one end so that it can be placed around the wire, with the counter resting on top of it. Wrap the other end in inner tubing for protection. Place a small block, also wrapped in inner tubing, beneath the outer edge of the striking arm.
