A few questions that I am having a hard time finding answers for in the forum: I will be tanning fox, coyote, beaver, mink, muskrat, otter. How long can I leave them in the relaxing bath before I begin having problems with them? I would like to shave the beaver hides by hand. Can I, how do I, or do I need a machine? The ears on the fox and coyotes are not turned and are beginning to darken and have remained soft and flexible. I would like to relax the hides so I can turn the ears to prevent the hair from slipping. That is why I am wondering how long I can leave them in the relaxing bath. I will be using water and salt to relax them. Any suggestions? Thanks for the help.
