Finishing the Oak Bark Tanned Deer Leather

Cute  and  practical, just how I like 'em!

Cute and practical, just how I like 'em!

Last winter I started a project oak bark tanning a deer skin to make leather for the axe strop project.  The project follows the collecting and processing of materials to build pocket sized sharpening strops as prizes for people who completed the Axe Cordwood Challenge.  I'm making everything I need for the strops and decided to show the whole tanning process and everything else in a series of videos.  Almost 6 months ago, I laid the prepared skin away to tan in oak bark.  It sat in there about 4 months longer than it needed to, but I took it out and finished it this week, and it looks like it turned out pretty decent.

The leather is perhaps a little light and spongy, "Empty", as they say in the tanning trade.  Emptiness results from the loss of structural proteins in the skin by chemical or bacterial action.  It isn't much of a surprise considering that I over-limed it to start with, and that it sat in a weak vegetable tanning (plant based) solution for 4 months longer than it needed to.  Those are actually the type of things that a tanner might do on purpose to a hide in order to make the finished leather soft and pliable.  That's not what I was planning though.  I would prefer a rather firm and weighty leather for this project, but that is not even the nature of deer to start with.  Deer skin, at least our deer skin here in the Western U.S. has an open, coarse-fibered, low density character that lends itself well to softened leathers.  It would have been better to move it through the process faster with shorter liming time.  But, a process that uses somewhat preservative solutions like lime and tannin, begs for procrastination.  Add that I have to make videos of it all and it's a perfect storm for not getting things done in a timely manner.  It will probably work fine for the project, but I haven't assessed it closely yet.  If it doesn't work out, I have plenty of other skins I've tanned over the years that are suitable and I got to show the process start to finish, with some of the warts and mistakes that any home tanner is likely to experience.

The next steps will be making the wooden paddles, making glue and putting it all together into the finished product.  I only need a small amount of leather for the project.  Seven brave and industrious individuals chopped one cord or more of firewood for the cordwood challenge using axes only and will receive a finished strop and a leather patch when they are made.  The balance of the leather will be stowed away with the rest of my leather cache, to wait for a suitable project.

Axe Strops #5, Rinsing, Drenching and Bark Preparation

In this segment we repeatedly rinse and scrape the skin to remove lime and unwanted gunk, then soak the skin in an acid drench made from fermented bran and water.  Oak bark is prepared by chopping and cooked to make the tanning solution.

Peeling Oak Bark for Tanning Leather and Apple Breeding Update

Here are a couple of recent videos I did on the stuff I do around here.  One is a short update on labeling and protecting fruit that was pollinated earlier this year as part of my apple breeding project.  I talk a little about the breeding parents and related stuff, but it's pretty straightforward and short, with a quick visit to my new pig. The second is a follow along while I cut down, cut up, and peel the bark off of a tan oak tree that is infected with the organism involved in sudden oak death.  I use the bark for tanning skins.  I'm working on a book right now on tanning with plant materials like bark, various leaves and pods and stuff like that.  Writing, research and experiments around that project now consume most ofmy time, energy and thought.  In the video I show a few pieces of leather tanned with oak bark, peel the bark, split the wood and clean it all up.  There are few things I'd rather do with my time than that type of forestry work.  Splitting wood, playing with wood, using my axe, burning brush to make charcoal, etc..   is all my idea of a good time!  woo hoo!  It's really hard for me to cut these videos down and focus them in.  There are so many satellite topics I want to talk about!   Definitely some stuff coming on axe use, wood splitting tutorials, forestry and forest ecology, and lots of tanning and skin working stuff.
