Perhaps a little clarification. When I say I clean skin that is not completely true. There still is need of fleshing although it is minimal. I don't sweat a few small patches of meat and I do not worry about the fat around the legs. Those things flesh easy so I would probably be more truthful to say semi-clean skin.
It doesn't take me long to flesh though when done this way and there is little fat to make its way onto the fur.
Tonight I skinned and fleshed 2 blanket beaver, a small otter and a mink. I was in the fur shed 2 1/2 hours. That includes building a fire in the stove and doing a little clean up work where I had been working on traps so probably 2 hours fur handling.
There are better and faster. Here's a good video to watch.
I do things a bit different then Carl but the basics are the same and he is faster then me.
