I have tanned bear, deer ,coyotes, etc with this solution. tanning is a lot of work but it will look good and last. You need enough to soak entire hide. First scrape all fat of hide and wash it out good in soapy water to get all blood and dirt out. Solution is one gallon soft water, one ounce commercial strenght sulfuric acid ( from Co-op), and one quart salt (fine water softner salt). Soak hide for 3 days remove wring dry, and soak overnight in pail of water with 1/2 cup sal soda to neutralize acid. Do not smell fumes when pouring acid into water, wear gloves and safty glasses. Work hide over a round object like the end of a baseball bat. Do not let hide dry hard, if it does wet it with water. Keep working it as drys. Treat finished hide with neatsfoots oil.
