DixieDuke, by trying to find shortcuts, your actually making things harder than they need to be. Forget about the battery acid. FAR too dangerous and there are much better acids out there. It sounds like your wanting to make your own fleshing machine, forget that too. A homemade flesher will never be able to compare with a commercial one, and you really don't need one for thin skinned animals. A fleshing machine shaves the hide thin, it doesn't break the hide, though the thinner hide breaks easier. Also, someone told you wrong that you can use leather conditioner in place of tanning. Hides must be turned into leather, otherwise they're still raw skins. Go to Bruce Rittels website here, http://rittelsupplies.net/current_pricelist.html and order the EZ-2000 kit. It will come with directions that will walk you right through it. It's also a good idea to get a book on tanning to help you understand the process.
