Below is an article that I wrote a while back. I will try to find the photos that go with it later. Kind of a long post but it is a good way to skin beaver.
Beaver Skinning Made Easy
By Jim Toney
If you invest the time, effort, and money into trapping but; don’t take the time to learn how to handle fur, you are just wasting your time and a valuable resource.
Most beginner trappers (myself included), just jump right into trapping without first learning how to put up fur once it is caught. For the most part, we are competent outdoorsmen who learn quickly but sometimes it is better to at least have an idea how to do something before you start.
The following is a simple, step by step method of skinning beaver.
Step #1 (photo #1) Make your beginning cuts around all four legs and the base of the tail. Remove all four feet from the beaver. The front feet will usually twist right off. It is usually necessary to cut the tendon on the back of the hind legs to remove them.
Step #2 (photo #2) Next, make a long cut from the center of the lower lip through the anus to the base of the tail. This cut is easiest to make using a knife that has a good gut hook.
Step #3 (photo #3) Continue skinning the beaver at the belly cut (the long cut). Carefully skin as close to the hide as you can, working your way past the legs toward the back. When you reach the center of the back you can turn the beaver around and do the same with the other side. When you reach the head, work your way past the ears to the eyes. At the eyes, you will want to skin as close to the skull as possible to avoid cutting the eyelids. When you reach the nose, skin all the way to the tip of the cartilage and cut as close to the hide as you can. Now just finish skinning down to the lips and around the mouth. Once the hide is removed from the beaver, it should resemble the one in photo #4. Now it is time to flesh the hide.
I won’t go into detail about how to flesh the hide since most beginners don’t have fleshing beams and fleshing knives. The most important thing to keep in mind is that ALL of the meat and grease must be removed from the hide to prevent slippage. You can do this with a good sharp knife and a little effort. As you get more efficient at skinning you will all but eliminate the need to flesh.
Once you have completed the task of fleshing, it is time to stretch the hide. You can either use a beaver hoop (which is what I prefer), or you can stretch it on a piece of scrap plywood. Although the hoops are easier, the plywood is probably the most convenient for the beginner.
To stretch the hide you simply tack the hide to the plywood fur side out, trying to maintain either an oval shape or a circle depending on your market or your own preference.
Using small nails, tack the nose to the plywood. Gently stretch the hide down and nail the center of the tail cut to the board. Do the same with the sides. Work your way around the hide until you have nails at approximately one to one and a half inch spacing all the way around.
That’s about all there is to it. With a little practice you will refine this method to better suit your own individual style.
Until next time, keep our heroes in your prayers.
