Doug did a great job on this cabinet. He had to work very hard to make it useable again. It was so badly damaged. I even got to lend a hand, literally, and helped push on some of the metal as he was heating it up with a special rotary metal plate which was attached to a buffer. Some good gloves helped protect my hand from the immense heat coming from the other side. I'm very happy that we know someone as knowledgeable and nice as Doug. Thank you.
Travis, I'm so glad that you got the compressor to kick on and circulate that Freon 12!

How exactly do you shrink a metal panel? Dry ice? There are several ways. If the panel shape will allow, the power hammer, Pullmax, or Eckold KraftFormer are excellent ways to shrink a panel very quickly. Unfortunately, the shape of the panel wouldn't fit into any of those machines, so I used heat. When you heat an area on a sheet metal panel and the surroundings are allowed to remain cool, there is some compression that occurs at the area where the hot meets the cold. The heated material expands but is held captive by the cooler surrounding material. As it expands it is compressed into itself. Once it cools, it has a slightly lesser surface area and slightly larger thickness. It is a very slow process, but it works. That seems quite brilliant, and more of an art form than anything.
