Worm gear made from an electric lock actuator for car doors

video Worm gear made from an electric lock actuator for car doors
Some cars have electric locks on doors. An actuator - is a device used to move parts of such locks when electric signal comes. An ordinary car lock's actuator consists of an electric motor and a gear wheel which moves a gear lath.
This motor and a gear wheel can be used to move robots or other devices. But the final rotation speed is pretty high for directly rotation of wheels. A worm gear noticeably decreases this speed. The following instruction shows how to create such gear without any special milling equipment.
Required parts and materials: copper wires, steel stripe, a wheel for furniture, a car lock's actuator and some bolts and nuts.
Gear ring may be attached to a wheel by thermal glue - it is a plastic glue that melts when heat is applied and gets solid at room temperature.

Just found this one. Very inventive. Excellent job.
I love this idea
