Nifty!
Nice to see this thing still has some life left in it. Probably not the most efficient unit around, but for nearly free one can't complain and on a hot, humid day this will make life bearable in the shop.
Now you need to get your son a Norge burpilator washer and matching flocker dryer to take care of shop towels and such, since you obviously have some good B/W karma going on!
