Happy building!

yeah, i was thinking about running the motor straight to the threaded rod and a nut to the piece trying to move.

so finding the right motor/rod combo will be the trick. I will be looking into this more. what i will have to "research" is if the threaded rod will be the same as gearing down the motor. if a servo motor's gears gear down its motor to spin a wood auger drill bit (say for example) 1" per second then if i get a rod with x amount of TPI(thread per inch) i would need to get a motor that spins that same number of TPI per second to achieve the same as the servo.
