Rip cuts are commonly made with a table saw, but other types of power saws can also be used, including a radial arm saw, band saw, and hand held circular saw.In sawmills the head saw is the first rip-saw a log goes through, which is sometimes a gang-saw, and then the cants may be resawn using other saws and then edged in an edger and sometimes cut to length by a crosscut saw.
Rift sawing is a woodworking process that aims to produce lumber that is less vulnerable to distortion than flat-sawn lumber. Rift-sawing may be done strictly along a log's radials—perpendicular to the annular growth ring orientation or wood grain —or as part of the quarter sawing process.
The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American plate. It formed when the continent's core, the North American craton , began to split apart during the Mesoproterozoic era of the Precambrian , about 1.1 ...

Axes made of copper, bronze, iron and steel appeared as these technologies developed. The axe is an example of a simple machine, as it is a type of wedge, or dual inclined plane. This reduces the effort needed by the wood chopper. It splits the wood into two parts by the pressure concentration at the blade.
How were the medals for the 2024 Paris Olympics made? Each gold, silver and bronze medal at the 2024 Paris Olympics features an 18-gram hexagonal chunk of iron taken from the Eiffel Tower.
Steel or iron are usually avoided, as iron can react with moist timber to produce rust staining, or some tannin-rich woods such as oak or chestnut will provide indelible blue-black iron tannates. After heat bending the wood, clamping the wood into a solid mold will reinforce the bends made to the wood while drying, preventing the wood from ...
