After hunting or processing livestock for the table, it's a shame to have to toss out a nice pelt. Here is a method of tanning hides that is low cost and low labor compared to other methods of “custom tanning.” I've personally used this system to tan sheepskins, deerskins, groundhog pelts, rabbit hides and goat skins. The procedure can be used for all kinds of mammal pelts when you want the fur to remain on the skin. It results in a soft, workable hide, which can be used as is or cut up for sewing projects.
Salting Fresh Skins
Fresh hides right off the animal should be cooled immediately. Trim off any flesh and scrape visible fat from the hide. Place the skin in the shade, laying it completely flat with the fur side down, preferably on a cold concrete or rock surface. When the skin feels cool to the touch, immediately cover the fleshy side completely with plain, uniodized salt.
Use three to five pounds for a sheep or deer skin. Don't skimp.
If skins aren't salted within a few hours of removal of the flesh, you might as well forget it. They will have begun to decompose and will probably lose their hair during processing.
Transport the skin flat. We've had problems with predators gnawing the edges of skins, so put the hide somewhere out of reach. You don't need to stretch the skin; just make sure it is perfectly flat, with no curled edges. If you've lost a lot of salt while moving the pelt, add more. The salt will draw moisture from the skin and liquid may pool in low spots. Just add more salt. Let the skin dry until it is crispy. This may take a few days to a couple of weeks. When completely dry, the skin is very stable and won't change or deteriorate appreciably.
When you're ready to tan the skins, assemble the following:
7 gallons water
2 pounds (16 cups) bran flakes
16 cups plain or pickling salt (not iodized)
2 large plastic trash cans (30 gallon) and one lid
4 foot wooden stirring stick
3½ cups battery acid (from auto parts store)
2 boxes baking soda
wood rack or stretcher
wire bristle brush
This recipe makes enough tanning solution to tan four large animal skins; or ten rabbit skins; or about six medium-sized pelts such as groundhog. (Cut the recipe in half for fewer skins).
Mixing the Solution
A couple of hours before you plan to tan, soak the dried skins in clear, fresh water until flexible. Boil three gallons of water and pour over the bran flakes. Let this sit for an hour, then strain the bran flakes out, saving the brownish water solution. Next, bring the remaining four gallons of water to a boil. Put the 16 cups of salt in a plastic trash can. Pour the water over the salt and use the stirring stick to mix until the salt dissolves. Add the brown bran liquid. Stir.
