First, I clean skin. After putting about 16 nails in the skin to keep it snug, I literally shave the entire skin with a VERY sharp knife. After shaving I go over it with a paintscraper to get as much moisture/grease out of the skin as possible. I dry in a 8x6x4 enclosure with two fans and 500 watts of IR lighting as a heat source. The relative humidity of coastal Oregon in the winter runs about 90% so the fans and heat are an absolute nessecity. It sounds like a lot of extra work but I still finish beaver start of skinning to last nail in less than 45 minutes, usually closer to half an hour. I taught beaverpeeler this method about 35 years ago and he does a comparable job. As his catch went up into the hundreds, I did notice a slight tendancy on his part to "get a little lazy" on the put up!! LOL
