Sorry I haven't got back to you before now. I had to get me some treestand time. To dehair a deer hide, mix 1 lb of Hydrated Lime with 10 gallons of room temperature water. Mix well to desolve the lime. Submerge deer hide and stir it around for a minute or two then sink it by placing a heavy rock or brick on the hide. Stir daily. After 3 days, give the hair a gentle tug. It should be getting loose. Continue stirring and checking daily, until the hair "slips" from the hide with little effort. Remove the hide and lay it over a piece of fire log and use a blunt object (a 6 inch piece of 2x4 works well) and scrape the hair off. If you find any stubborn spots, just re-soak it another day. Continue until all hair is gone. When de-haired, wash several times in running water until clean. Then proceed with tanning. There are several commercial de-hairing products on the market that you may wish to try. Hope the helps.
