Inland All In Wonder Lapidary Machine

Ol' Timey: Lapidary Arts - Cutting and Polishing Stones

Today we fashioned some rough pebbles into smooth, beautifully polished stones. The best stones to use are relatively low on the Mohs scale of hardness such as soapstone (2), and serpentine (2.5). If you can scratch the stone with a piece of steel it should be soft enough to work with. You do not want a stone that is too soft though such as talc (1 on the Mohs scale) because it may break apart. To work with stone it will help to have a machine. We used the "Inland Swamp Top All-In-Wonder Lapidary Machine." It is a basic wet saw as would be used to cut tile but the top flips over and different attachments can be added for different purposes. From the middle ages up until the industrial revolution slabbing and polishing wheels were powered by water wheels in rivers. In Vermont, marble, slate, and granite are abundant and have been mined from the hills for hundreds of years. In fact, the first marble quarry in the United States was on Mount Aeolus overlooking East Dorset, Vt. Here is a description by Ronald Robinson of the marble quarries of Vermont in 1890: "In the great pits, yawning wider and deeper every year, men and engines, in sunshine and in storm, delve all the seasons through. When the landscape is bright under the summer sun they may be seen, like ants toiling in their cells, hundreds of feet below the surface. Now and then an ant grows into a burly, grimy man, climbing the giddy stairs; or a small watercarrier, bearing, with careful steps, his heavy bucket to the thirsty workmen..." The uses for polished stone are wide and varied. One could make soapstone chess pieces, obsidian arrow/spear/axe heads, obsidian scalpel edges such as the Incas used for surgery, inlays for belts/staffs/knife handles, mosaics, jewelry, paper weights, decorations, the list goes on. Today we just made some nice polished stones that can be altered further for various purposes. Here is how to do it. After you select your stone, examine it to find what part of it you think will look best. You may want to check for cracks and faults as well to help determine which parts you would like to eliminate. The first step is to shape your stone using the diamond trim saw. Remove the top of the machine and set the blade in. Make sure to secure the arbor nut and note that like a table saw, it is tightened using a left hand thread. The trim saw will essentially achieve "slabbing" on a micro scale. Fill the water reservoir of the machine and connect the drain hose to a waste bucket.
