The completed fire kit, with the tools used.
The hearth board and the spindle are from an old cedar fence rail, probably about 100 years old, which I got from an old fence at Sheldon. Using the stone wedge in the right foreground, I split the spindle off the hearth, so the spindle is, in effect, harder, because it is end-grain. The grain in the hearth is vertical, i.e., it runs up and down, so that when you are drilling down through the hearth board, you are constantly working against both hard and soft wood. (It’s hard to explain ... but it makes a significant difference.) |
Splitting the corners off the spindle.
Since I am using straight-grained wood, splitting wood off the square corners resulting from the initial split from the hearth, is much faster and efficient than any other technique. This illustrates the principle that the careful choice of materials and techniques makes a huge difference in reducing the time and energy used, and in improving the quality of the finished product. |
Planing the spindle using the unifacial chert tool.
The edge of the chert tool that is against the wood is smooth and unworked. This means that the edge can be quite sharp, though not necessarily strong. Note the leather gloves and the leather leg pad. |
Unifacially Flaking the Spokeshave.
The flint tool is a piece of Onondaga chert from the north-east shore of Lake Erie. It’s a fine-grained thinnish flake, that I have worked unifacially, i.e., on one face of each edge only, so that the edges are chisel-shaped, not knife-edged. You can see the smooth un-worked surface facing you in this photo. This kind of edge is generally better for most aspects of woodworking. One corner of the tool is being unifacially worked here, to make curved surface, to turn it into a spokeshave, to round off the spindle. I used the deer antler time to work the chert. (And always, either leather pads, or leather work gloves — safety is important! We don’t have the lifelong practical learning to handle tools without protection.) |
Using the spokeshave to round the spindle.
I am pushing the spokeshave away from me, so that any spalls or tiny flakes of chert worn off, generally preserve the shape of the tool. |
Sanding.
About as low-tech as possible! I used a coarse piece of sandstone to abrade the wood. (Concrete works well, too — but that’s too much like ‘cheating’!) |
