I would like to use some small DC motors to turn a gear. I have noticed there are some different ways to attach a gear, such as a c-clamp. I am not really familiar with doing this, so I want to try to find the best way to do it generically, I am working with a lot of surplus parts.

With larger gears, there is usually a key way cut in the inside of the gear's center hole and a matching key way cut in the shaft of the motor. A flag metal piece, amazingly called a key, spans the two slots and locks the shafts from turning. Most gears have a set screw to hold the key from shifting.
If the load is not too large, then the set screw can be used to a flat on the motor shaft.
With small motors and small gears, there isn't enough material for cutting slots or providing set screws. The most common solution is to glue the gear to the motor using epoxy or LocTite type materials.

If you connect an electric motor to a load through a gear, and the load jams, the motor will burn out. You need a friction drive first.
Fix the gear, and a pulley wheel, to a shaft. Run a rubber driving belt or band from the motor spindle to the pulley. You may need a small pulley on the motor spindle, but remember that the rule for this friction stage must be maximum speed, minimum torque. When the load jams, you lose some rubber, but not the motor or gears.
