I was able to tear the hide at this notch. I would appreciate some feed back soon. I put five more hides in the water and ash solution yesterday. Sounds like you're dealing with cold weather conditions which can affect tanning time. In warm weather, several days to a week are sufficient for tanning.
Cold weather can lengthen the time up to several weeks.
I would wash the 1st hide in clear water and put it back in the solution for a couple more weeks. Be sure to stir every day. The extra time shouldn't hurt the hide and it will be fully tanned. Use this hide as your experiment. As soon as the hair slips on the other five hides, I would wash them in clear water, wring them out, resalt them, and let them dry.
