Rotor; I've only tanned 5 deer hides, but this is what I found out. Got the stuff from vandykestaxidermy.com (Lutan F). Complete with instructions.
1st--the skinning job makes all the difference. the less flesh left on it, the better. Fleshing is slow work. All my hides were hair-on.
2nd--get lots of non-iodized salt. (canning/pickling salt)
3rd--I used 2 of the large clear plastic storage tubs.
4th--you need to dispose of a lot of salt water. It really kills grass.
5th--you need a stretching/drying frame.
6th--takes about 10 days to 2 weeks to do it. The actual tanning stage is critical on timing. You have to plan on when you put the hide in the tan, so that you will be available to take it out when it is time.
7th--I never managed to get the soft texture like the tanneries do.
8th--don't let any part of the process get below freezing. The liquor won't freeze, but it screws up the hide.
9th--while you are doing it, you will wonder why you didn't send it off.
10th--when you finish, it will seem worth it, though. I kept 2 of them, gave 2 of them as gifts, and did one of them for my oldest grandson on his first deer.
Not looking forward to it, but will probably do a few more.
