Hello, I have a geared ac motor; I'm not sure what the correct term would be but it will only turn one direction regardless of polarity. What I need to accomplish is to reel in a string of about 20" until a set point where it would be automatically fed back out. It will be an elevator of sorts to lift a ball (about 5 lbs) about 20". The end points I know can be determined through simple limit switches which I know how to setup, again its the mechanical aspect which has gotten me thinking. I realize a dc motor would be much more convenient for its reversible nature. It would have to have a gearing that would be able to pull in this string with a load of about 5-6 lbs on it, ideally the full 20" could be taken in under 30 seconds. I'm thinking a simple battery powered reversible drill would serve the purpose well. Does anyone have any thoughts on where to locate one, I know the prices are quite steep on e-bay with batteries included which I would not need. Ideally I'd be able to use my current motor. I am willing to use dc and in reality if a cheep source were to preset itself would be preferred. Any thoughts are welcome. Thanks in advance....
