Auto Tanner...A new question?

Submitted by David Hammond on 1/15/1999. ( the_hammonds@msn.com )

I am apprenticing with a Taxidermist that is trying quell my desire to use an auto tanner. I know basically the methods in their use and it seems great, but here is his argument against them.
The normal salting, pickling, and tanning process works to draw the proteins, fats and oils out of the skin and REPLACES them with the tanning chemicals. The Auto Tanners use pressure to quickly get the tanning solution deep into the hide. Question (What happens to the proteins, oils and fats in this process?)

David,
Not trying to avoid your question but let's put some more cards on the table like:
The air pressure in the tank is approx.40 psi but what is the actual
pressure on the skin while it is under water? These questions are'nt
meant to downgrade the machine but to figure some things out.It is claimed that the pressure forces the tan into the skin and replaces the
items you asked about.I'm not sure here.I used the tank last year with some good results but sometimes I had more shrinkage than I wished for.Fortunately this year I'm seending everything out.Had to free up some time.


aluminum sulfate

What are the advantages and disadvantages of using these in the uato tanner . Are there any problems to expect in the future with Alum sulfate tanned skins ?


Glad Someone Asked

Not having any experience with the pressure tank, I've kinda withheld comment. But, what David said is exactly what I have felt all along on this subject. I, myself, can't believe that the solutions used can do a complete job of pickling and tanning a skin in that short amount of time, pressure or no pressure. The job the acid needs to do, and the bond formed by the tan, well, I don;t see how pressure can speed these up. The numerous posts in the past about not getting any stretch because the skin was left in pressure too long serve to back this theory up. An untanned skin will give you all kinds of stretch, ask any powder jockey out there, that's why they use it. When skins are left in the tank long enough to actually tan the skin, stretch is greatly reduced, thus the solution of soaking the skin in water and it relaxes and stretches. Basically, you're soaking it until the aluminum sulfate releases, and "drops" off the skin, once again giving you lots of stretch.

I think the pressure tank idea has merit to it, if you actually tan the skin completely, but to do so won't be the big time saver everyone thinks.

As far as the Aluminum Sulphate goes, all I'll say is, if I, as a tanner, talk about using, people say I'm a Hack, and won't have a good product, so why should it be any different for you in shop? Maybe you should try using one of the better tans on the market and tan it completely in your tank and see how they turn out, and don't forget to shave your skins good first. Keith


I have done all of it with the tank.

This response submitted by John C. on 1/18/1999. ( )

I have use all of the tans out on the market in my AUTO TANNER, and it seems that all of them will work. (IF you follow directions) Also I have done some soft skins.

Now aluminum sulphate has been around as a tanning agent longer than any of us and I am over 40 so will it last? Who knows?

I do know that speed wise you will not save any money with the AUTO TANNER, time X wage = time + tannery charge.

What is one hour of your time worth?????

The only time you will come out with this, is do you want and need complete control over your tanning?

I have noticed a large amount of grease and grim or scum in the liqiud after tanning, it appear to be adipose skin fats.


I have went back to just the Alminum sulphate as called for in the tank. Having over 20 years experience I feel this does a good job of tanning, and yes I have used tannery prepared skin and some skins should be tannery preped. Bear, Hogs, African.

I doe know this is far better that powder, and cream tans. and yes I have salted and pickled the hides for cream tanning. I will tank tan all the short hair deer, as I feel it is a good option to have. Even with a few long haired animals. Giid luck John


Another comment and question

This response submitted by Dave B. on 1/20/1999. ( )

Just bought a computer, so bear with me here.
I also bought a auto tanner about 4 months ago.
I used to formic acid pickle, but got tired of the salt
mess and mixing 30-40 gal of pickle. Now use about
8 oz. of aluminum sulphate and 8 oz. of salt and
about a teaspoon of sodium carbonate, oh and 1/4 cup of
oil to tan deer. I have never been happier I have not
lost any stretch in fact have gained some. I read what
Bruce Rittel wrote about oiling after pickling in
tank instead of in it, that works well also I got lazy
one night and instead of putting the skin back in
the tank after fleshing I liquitanned it, turned out
great. Auto tanner is the way to go.
My question is what type of oil is best to use if
oiling after pickling in tank,its like going to
a resturant there are so many choices you dont know
what to get. see ya!



Auto tanner- Can you reuse solution?

This response submitted by Justin Sabol on 2/9/1999. ( MSequus24@aol.com )

What I really need to know is if you can reuse your tanning solution.
So far it has all worked great but to cut cost on expenses even more, I would really like to get an answer. It seems logical to reuse, yet it doesn't say in booklet and it seems the measurements would be off.
Please let me know. Thanks,Justin
