A stone being split using a single plug and feathers. Multiple sets of plug and feathers are typically used to split a single, large piece of stone. The stone is first examined to determine the direction of the grain and to identify any potential defects. After the location of the intended split is chosen, a line is scored on the surface of the ...
Traditionally, these posts were manufactured in-place by drilling lines of holes directly into the freshly exposed, soft limestone bed (only about halfway through). Then feathers and wedges were set into the holes and the wedges hammered to split the posts off. [21]
Lifting the stone a small distance from the ground before hoisting is the best way to test a lewis. Any sign of looseness or damage should be corrected by adjusting the lewis hole or packing the lewis with metal shims. To bed a stone using a lewis, the stone is placed on dunnage laid flat with enough clearance for a mortar bed to be placed ...
Stone was cut using plugs and feathers, where a series of short, small diameter (typically 30 mm) holes are drilled in a line where a cut is to be made. One plug and two feathers were inserted into each hole and each plug is hit in turn with a sledgehammer until the stone yields to the extreme tensile stresses produced.
Wedge — an unsharpened blade for digging, breaking and prying. A San Angelo bar has a wedge at one end. Chisel — a sharpened blade for cutting roots, digging and prying. A pinch point bar has a chisel at one end. Bars are typically 5 to 6 ft (1.5 to 1.8 m) long and weigh 15 to 23 lb (6.8 to 10.4 kg).
Stone claw tools are used to remove the peaks and troughs left from the previously used tools. Stone pitching tools are used to remove large quantities of stone. Stone nickers are used to split stones by tracing a line along the stone with progressive strikes until the stone breaks along the line. Powered pneumatic hammers make the hard work ...
Splitting mauls and splitting wedges are used to split wood along the grain. A narrow wedge with a relatively long taper, used to finely adjust the distance between objects is called a gib, and is commonly used in machine tool adjustment. The tips of forks and nails are also wedges, as they split and separate the material into which they are ...
Wood splitting (riving, [1] cleaving) is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing, the wood is split along the grain using tools such as a hammer and wedges, splitting maul, cleaving axe, side knife, or froe.
