Back into the woods – this time to find the materials to bottom the Dave Sawyer – style ladder backs and to start collecting parts for the next set of chairs. This was my first time harvesting hickory bark from the forest. I had been warned about how physically demanding the work could be with the tree on the forest floor and needing to work on top of it for hours. It definitely lived up to that reputation of hard work. After working two trees the first day (mistake – one tree is plenty), I came home completely exhausted, yet pretty happy to have bundles of bark.
The head forester at Berea dropped the hickory trees for me over a two-week span. Our season here is between late May and July 4th. The sap is up and the bark is slipping and it’s much easier to get it during this window than at any other time of the year. It’s best to peel the bark as soon as the tree falls, but I needed to wait a day before getting to the first couple of them. No trouble, they peeled well. I needed to wait a couple more days before working the 3rd tree – it still peeled, but took a little more effort to get it off the trunk. The last tree was peeled as soon as it was dropped and it was notably easier. This all happened in late May. Four trees is plenty of bark – a wild guess is that each of the 20′, 8″ diameter trees (the average of the four trees worked) yielded 5-6 seats each. That’s plenty of bark for my chair output, and enough to share some.
The bark came from a pignut variety of hickory. There’s not too much to harvesting it, though my ignorance shined through at a couple of points. The outer bark needs shaved away – that takes hard work, but it’s straightforward and relatively forgiving. The drawknife peeled that outer bark away quickly. It was recommended that the inner bark should be shaved thin – maybe an 1/8″ or a little less – but I left it as thick as possible. Mostly because it was tough to get a good, close, consistent shave while working on the ground, and because fatigue set in. It’ll need split each coil before it’s used for a chair seat.
Peter Follansbee’s writings were my foundation and research before heading into the woods. https://pfollansbee.wordpress.com/2017/06/19/hickory-bark/ That, along with Brian Boggs/Lie Nielsen DVD, Drew Langsner books and a few conversations with Steve Farmer (who’s collected and sold bark for years here in Berea).
Side note: I put thick into the ladder back. It cracked while drying on the diamond-patterned mineral deposit areas around the tight bends. Too thick. Splitting the thickness of the bark into an outer and inner (then using the inner for the seat) removes the dimond pattern and results in a more uniform seat that can be pulled much tighter. The outer bark isn’t waste – it can be used for other projects, though I wouldn’t put it in a chair. Lesson learned – work the bark thin for best results.
When harvesting bark, most slice the bark off the tree at a consistent width. Around 1″ or whatever is intended for the chair. I attempted that, but my knife wandered and I wasn’t happy with the results (it’s probably fine, minor changes in width disappear when woven into a seat). So I took some with the utility knife at 1″ and collected the remainder at a wider width – maybe 3″ or 4″ wide. I’m using a leather strap cutter in the shop to uniformly slice the bark to width. Soak the coil of bark for a few hous, cut it to width, then split the thickness. It’s more work after getting it out of the woods, but I am able to do a better job in the shop than while working out in the woods.
Thought on tree diameter. I’ve always heard that 6-8″ diameter saplings are best. After doing this, I figure that’s true for a couple of reasons. First off, it’s much easier to handle a smaller tree than something considerably larger. That was definitely my experience, as the 10″ sapling was much tougher to move around than the 6″. The other reason has to do with the thickness of the bark. The smaller tree had much thinner bark in relation to the 10″ sapling, possibly to the point that it will not need split again before using. That’s a big advantage – shave off the outer bark and some of the mineral striations and it’s ready for a chair. Obviously the larger diameter yielded a fair bit more bark, but there’s more work involved in collecting it.
After collecting the bark (and resting), I went back for chair rungs from the saplings. The next three chairs worth of rungs are now drying in the kiln, waiting for the upcoming “settin’ chairs.”
