Working with DC motors
1) Find a gearhead motor that's approximately the right speed and torque.
Surplus motors are widely available, try allelectronics
or C&H
2) DC Motors can be reversible or nonreversible, depending on the gearing.
To reverse a motor simply switch power and ground.
3) Shaft collars can be used to attach stuff to the motor.
5) An H-bridge circuit provides basic bidirectional control over a DC Motor.
