How To Use A Micrometer

When determining the score in a game of curling, there may be times where two stones appear equally close to the button by the naked eye. This is where the measuring devices are an essential piece of equipment in the sport of curling.

Micrometer

The micrometer is a measuring device used to determine which of two stones is closer to the pin - the exact center of the house. A micrometer works uses a pressure gauge to determine which stone is the closer one. The stone that is closer to the button will produce a larger reading on the pressure gauge. Now, we will look at how to use the micrometer.

Using the Micrometer

  1. First, place the micrometer behind the backline for a few seconds. This allows the metal to cool down to the temperature of the ice.
  1. After the micrometer is cool, move the stake into the pin. Check that the stake is resting securely in the pin - this ensures that the measurements taken will be accurate.
  1. Then, rotate the bar clockwise until it reaches the first contending stone. Adjust the pressure gauge so that it touches the stone. Rotate the micrometer back and forth once or twice to make sure that an appreciable reading is displayed on the analog gauge.
  1. The vices should agree upon and take note of the maximum gauge reading. Then, move the micrometer to the next stone.
  1. Rotate the micrometer back and forth once or twice to determine the reading produced by the micrometer. The vices should agree upon and take note of the maximum gauge reading.
  2. The stone that produces a higher reading on the micrometer gauge is the stone that is closest to the button. Remove the micrometer from the pin.
  3. The stone that was determined to be closer to the button should be moved to the button. The other stone should be moved out of the house. This is done to symbolize which stone is closer to the button, and helps the viewing audience understand what has happened on the ice.
