I found a local hobbyist who wants to sell me a rebuilt compressor and used air heater for $700.
Its a 3HP motor on my choice of a 60 or an 80 tank. Price includes delivery and placement (with my help of course). The tank is big for the motor but he says he can paint (low CFM) on it and DA.
Prolonged die grinding was the real limitation he's claiming. I'm going to get this wrong name wise, but I think he said the motor was a "Wayne 6200". Thoughts?
