I don't know how or why plasma cutting works, but it always brings a smile to my face. Getting ready to move and most everything has got to go including the 1977 Sears Craftsman air compressor from my parents 1 car garage from back in my youth. Scrap yard say's one end on any vessel must be open for inspection. Apparently some of the visitors that frequent the salvage yards will fill the tanks with water or ice to increase weight and profit. So today in preparation of this weeks trip to the scrap yard visit I cut off the end of the tank but couldn't stop! It's still voodoo magic!
