That darn salt is nasty.Even the fine powder.Kills lawns for a while real easy too.On greasier animals such as coon,beaver,and bear it helps to dry up grease if you let it flint dry.Meaning dry but still pliable.I never salt deer hides.Just freeze them or make rawhide to store them.
Alumunm sulfate tanning is a very safe fool proof way of tanning.
My roping method is pretty straight forward.Been using an inch thick nylon tow rope for years now.Tied on vertically to a tree or anywhere.I like it in the shade anyway.
I've used steel cable and skinnier lariot rope before too.
Length wise/cross wise/diagonal wise/and along the edge wise.Rotating the hide a 1/4 turn as I go.Smaller hides are less effort of course,but larger hides I lean into it pretty good.
In the beginning just stretch it in all directions far as possible while really damp.
I don't start rubbing it across the rope till the outside surface is considerably dry but a little damp on the interior yet,but stay with it till it's all completely dry.Timely work on areas more than others at times.I take breaks putting it into a plastic bag wadded up.
If I could get Robin to rope while I get a bite to eat would be nice but don't expect that of her.She does like the outcome of the process though.Made her a dress some time ago.
Usually always the edges and belly are dry first of course.Then I concentrate on spine,neck,and hip areas.
I touch it against my cheek to feel if areas are still damp.If it feels cool it's damp.If it's warm it's not.
You can see if the rope is tied high enough at the base that you won't need to worry about the hide hitting the dirt as you rope it on larger hides.It will catch and bunch up at the tie off point off the ground.
By larger hides I mean anything above 15 to 20 square foot.Smaller hides below that usually don't bunch up any.
I measure my hides by laying the hides on square foot tiles on the floor in my basement.
After braining/wringing/and twisting the hide I use the rope again to stretch it fully length wise and cross wise and then back to it's natural shape.Braining them usually only takes about an hour of soaking in the warm brain slurry.
I would like to note here that everything I do to the rawhide after braining through these stages is to stretch the hide to it's maximum before redunking into the warm brain slurry.....ie....stretching the fibers out to accept the brain oils.Especially the spine,neck,and hip areas.It's the reason why they come out soft from just 1 roping.Even the large hides.
Kinda wish I had some more beaver hides here myself.Love the dense fur on those guys.Look forward to seeing the work you get done and the process along the way.
To smoke a beaver hide I have it laced in hoop and have it suspended horizontally above a smudge fire in a small shed instead of in a tipi.No need to smoke those aluminum sulfated hides unless you want to give it a light brown appearance.Does'nt hurt anything.
A walnut stain is an option also boiling the husks and reducing the water content.Aluminum sulfate tanned hides just need a little scuffing and they will return soft again after drying from being wet.
It's tan has a very long shelf life of usage.
