Making method of simple standard watch

The method of making a simple standard table is as follows:

I. Materials:

1, a dial with scale.

2. Movable scale.

3. Stable support.

Second, the steps:

1. Prepare a dial with scale, which can be purchased at any watch shop or online. Make sure the dial is clear and accurate.

2. Prepare a movable scale, which can be marked with a straight piece of wood or plastic with a certain length. If there is no ready-made scale, you can cut it into long strips with white paper or cardboard and mark it with a pen or marker.

3. Find a stable support, either a tablet computer or a heavy book. Ensure that the bracket can stably support the dial and will not be moved by wind or touch.

4. Place the dial on the bracket so that the edge of the dial is parallel to the bracket. If the dial has a bracket, you can fix the dial with the bracket. If there is no bracket, you can use some tape or stickers to fix the dial on the bracket.

5. Place the ruler on one side of the dial so that the starting point of the ruler is aligned with the starting point of the dial. If the scale is too long or too short, you can adjust the position of the scale until the scale is parallel to the edge of the scale and the starting point is aligned.

6. Adjust the end of the scale so that it is aligned with the end of the dial. If the end point is not on the dial, you can move the position of the ruler until the end point is parallel and aligned with the edge of the dial.
