I have read about Urine tanning,never tried it and feel pretty sure I won't.
I do a lot of brain tanning ,just brains ,sometimes add egg white. You can do hair own the same,it is just more trouble and will take much longer in the stretching and drying faze of the process. You don't even have to rack the hide up if it has been defleshed already.Put it in the brain solution and leave for a few hours the first time,take it out and ring it,then back in the brains,then if you plan on pre smoking that would be the time,dry it out some and sew it up and smoke it,flesh side.Then back in the brains 3 or 4 more times,ringing in between each time.then work it until it is dry,this will be the tough part with hair on,it takes several hours of stretching and drying with the hair off,it will take much longer with the hair on.
