<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></DIV>
