Hey John,
 I hope this finds you well! That sounds like a pretty good idea. I now have a different problem now. The 2 left units are running slow, about half what the others are. The fan motors are getting warmer than the others. I took one of the fans from the units that I took off, and took it apart. Looks real good inside with the exception of the ball bearing. I am going to go buy 4 new ball bearings today and change them all, that should get the beans in the ground. Well, at least I am getting a reputation around here for taking rusty old junk and making it work! Not too many can make that claim!!!
I'll see you a week from Saturday!
Have a great day!!!
Andy
