Line 1: Line 1:
 +It is possible to to drive a tiller using a winch drive. ​ I have success with this using a 1 inch pipe mounted to a windshield wiper motor. ​ A line is wrapped around this pipe 5 turns, and connected to the tiller.
 +The alignment of the pipe is critical to ensure the line does not walk to the ends.
 +The advantages over tillerpilots or linear actuators:
 +   * use windshield wiper motors from cars, available for very cheap. ​ These motors also have two speeds.
 +   * easily adjust the gain by using different size pipe (recommend 1 inch or smaller diameter)
 +   * reuse existing line connections from windvane
 +   * testing shows this is more efficient than using a tillerpilot
 +The disadvantages:​
 +   * Slack in the lines gives more play in the system
 +   * More work to connect/​disconnect lines than lift tillerpilot from pin
 +   * More involved mounting to the boat
 +   * lines across cockpit
