I was Googling around and found this topic in the archives: http://www.taxidermy.net/forums/BeginnersArticles/03/a/03B2AFEE99.html To efficiently break larger (deer, cow) hides in a tumbler, does it need to be at least 6' high by 4' wide? For smaller skins...rabbit, beaver, coon, I'm assuming the other size mentioned 2' 1/2" drop would be fine? And on this topic: http://www.taxidermy.net/forums/TanningArticles/02/f/02726E78E4.html Do most people with an autotanner NOT salt/pickle before popping them in the tanner? Good / not so good results? Better results if you go through the whole process: Salt, pickle, neutralize, then tan? I know you have to flesh and shave before popping them in-just not real sure on the results one would get from not salting and pickling first. As far as I know, it's rather important to lock the hair in.
