<div>Alan,</div><div>That is a very slick motor alright, but it needs a controller. You know how I try to avoid electronic components whenever possible. Also i am trying to keep the cost down by using parts that I already have. I have a satellite dish actuator and I have a trolling motor on the shelf. I am picking up the actuator today from the shop and bringing it home to tear down. I am quite excited that it might be DC.</div><div>Hank</div><div><br></div>

<div>Alan, </div><div>I think they are probably song enough, I just swap the AC motor out. I don't need 400 lbs to do the job but I need 400 lbs of ballast. I am actually planning to make a moving cradle that also carries the oil filled batteries. I don't know how much force it will require, but, the cradle will be on rollers to make it easy.</div><div>I am ready to test for balance, so I will have to switch over to building a test pool. My plan to put an in ground pool in my new shop is out now because there is a giant lathe in the way.</div><div>Hank</div><div><br clear="none"></div>
