That tire machine has paid for itself more than once. I have been gravity balancing wheels but ran across the balancer the other day and could not pass it up.
That look like the beginnings of a GREAT shop. A guy that I know is going out of business, and selling his tire machine and balancer. A friend and I are going into together on it. So, I will probably have to call you AGAIN..lol....to get advice on how the balancer works.
