Gears, for the most part, are described by the number of teeth they have. A 24t gear, for example, has 24 teeth. (The "t" stands for "teeth.") Figure 2-3 shows a photograph of the various types of

There are two types of bushings in the RIS kit: regular and half-size. Both fit on shafts and are used for securing a shaft in place or for spacing. Figure 2-4 shows the bushings.
