The easiest thing to do is look up the gear you want in a gear catalog. They are free and easy to get. Then use the major diameter and the pitch information on that DP. Keeping it simple.....and basic... Diametral pitch is the number of teeth per inch or cc. It determines the pitch diameter of a gear because it has to come out to an exact number of teeth with no remainder. Using the numbers from the text draw in one tooth from the center of the bottom to the center of the bottom on the other side. The tooth will occupy the diameter of the round divided by the number of teeth. Then make it a circular pattern of that count. That being done you use the pitch diameter to figure distance from one gear to the next reguardless of your drawing actual dims. The pitch diameter is where the teeth actually do most of their contact and work. The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
