Step 2: Disassembling the Clock
Once you've got the face covering removed, you're going to want to disassemble the clock mechanism. Don't worry though, you won't have to disassemble the entire thing, just the hands. There should be a pin that secures the two (or three - mine only has two) hands. Take it out carefully.
Next, remove the minute hand carefully so that it doesn't bend. If you bend it, try and bend it back into place. Also, The minute hand should come off without any trouble.
After removing the minute hand, remove the hour hand in the same fashion. It should not be hard to remove. But take care not to bend it. The minute/hour hands just rest on the rod that is protruding through the face of the clock, but they fit snugly enough so that they won't just fall off when the clock is held upright.
After removing the hour hand, remove the face of the clock. Try to slide the flat edge of your scissors into the edge and then pry it out - you will need it for later.
Take your ruler and measure the diameter of the face. This is important to know. Mine had a diameter of 6 inches. You can find this out by laying the ruler across the face from 9 o'clock to 3 o'clock because there is a 180 degree line between those two numbers.
