I do mine a bit different. I skin them up the sides like in the video except I separate the two sides. Skin up both sides a few inches. Then I put them in a vise, grab the edge w vise grips and pull. The side strips off real nice, repeat w the other side. Then I clamp them to my fleshing beam and flesh. Throw the stripped tail and fleshings into a bucket and out in the sun it goes. Making tail oil.
