- Need help with gearing of barn door drive, for astrophotography.
So I'm a college student currently doing A-Level Physics, I am attempting to build a type 4 double arm barn door tracker and although it has been a complicated project, I believe I've got all the planning done, however, I have a 2Rpm motor, a PWM motor controller, 2 9v batteries, an M8 threaded rod. I want to know how I can use the motors turning action to turn the threaded rod. I was thinking of using cogs/spur gears but in my head I need something that has a threaded inside (like the inside of a nut) to allow the friction needed to turn the rod. Please could someone advise me on what I would need and if the electrical circuit (motor, pwm controller and 2 9V batteries) is viable.
Cheers
Adam
