cheep 3 volt dc motor nut and bolt actuator Answered
I'd like to make a cheep motorized actuator using a long bolt, nut & a small hobby motor to spin the bolt. I like to know how to attach the small motor to the bolt, or some way to spin the bolt. All I can think of is drill a small hole in the bolt, then J/B Weld the motor on the back. Is their a better way? Not only that but, what do I use to mount the motor at one end & the other end of the bolt to spin freely.
