Not to be a wise guy, but why don't you just go back to the Lutan if it's been working for you? Sounds to me like you have two people who really don't know how to use alum giving you advise anyway. The first guy is using way too much alum and salt both for a tan, the second guy confuses me too!

Most of the advice there also shadows what Keith is telling you. With all the great products out there today, I don't understand why anyone would use alum except for making pickles.

I agree with George and Keith. But if you choose to use alum, Jim Allred supply has what to me seems like a good recipe on his website, and seems like the step's are in good order. If you are tanning cape's or life size's to mount I would not experiment with any others than extra's. Alum can shrink hide's A LOT if not done properly. (No stretch).
George The older I get, the better I was
