I have two 10" model 66 powermatic table saws and love them both. I've had them both for 20+ years. One has a metal motor cover and one has a plastic cover. I never really liked the plastic cover. It did the trick of course but it never really gave me that "Saw Complete" feeling.
I know it's a long shot but does anyone have an old Metal cover lying around that you would be interested in selling? At this point I really want one and would not be overly concerned about cost, even if I had to have to ship from the West coast. If you have one, try me....love to talk. Chuck
