Jack,
Don't do it. You need to preserve the skin. If you don't it'll rot. You also need to remove the bone, there is marrow inside. If you are serious about preserving them, call a taxidermist in your area and pay for their experience. Deer feet are a pain that I don't like to deal with. I am a taxidermist. If you want to do it yourself call Van Dykes Taxidermy Supply @ 800-843-3320 and order kit BM-01508774 $19.99 + shipping. I still recommend the taxidermist, if you order the kit you'll see why. Remember "you get what you pay for"
