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.
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.
A flitch beam (or flitched beam) is a compound beam used in the construction of houses, decks, and other primarily wood-frame structures. Typically, the flitch beam is made up of a vertical steel plate sandwiched between two wood beams, the three layers being held together with bolts. In that common form it is sometimes referenced as a steel ...

The wood moisture content is above 25% on a dry-weight basis; The environment is sufficiently warm; Oxygen (O 2) is present; Wood with less than 25% moisture (dry weight basis) can remain free of decay for centuries. Similarly, wood submerged in water may not be attacked by fungi if the amount of oxygen is inadequate. Fungi lumber/timber ...
Wire nails are formed from wire. Usually coils of wire are drawn through a series of dies to reach a specific diameter, then cut into short rods that are then formed into nails. The nail tip is usually cut by a blade; the head is formed by reshaping the other end of the rod under high pressure. Other dies are used to cut grooves and ridges.
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.
Hewing is the last step in this whole process, which is also collectively referred to as hewing. Hewing is done on the logs sides with a broadaxe . Hewing occurs from the bottom of the stem upwards towards what was the top of the standing tree, reducing the tendency of the broken fibers to migrate inwards towards the eventual beam.
