A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the ...
Hand saws have been used for thousands of years. Egyptian hieroglyphics exist depicting ancient woodworkers sawing boards into pieces, and ancient bow saws have been found in Japan. Cut patterns on ancient boards are occasionally observed to bear the unique cutting marks left by saw blades , particularly if the wood was not 'smoothed up' by ...
The modern-day circular saw was invented around the end of the 18th century as a rip-saw to convert logs into lumber in sawmills and various claims have been made as to who invented it. Before the design was invented, logs were sawn by hand using a pit saw or using powered saws in a sawmill using an up-and-down saw with a reciprocating motion ...
The story of handsaws in the United States mirrors the technical and political development of steel. Sheffield, England, was the center of handsaw production during the 18th century and through most of the 19th century because of its fine steel and skilled craftsmen.

Bandsaw-type portable sawmill Swingblade-type portable sawmill More recently, with the invention of the Wood-Mizer in 1982, [ 3 ] portable bandsaw mills represented a dramatic shift in design. Unlike traditional mills, they used a thin-kerf blade of the type used on a band saw rather than a circular blade, which reduced weight and cost, and ...
Felling saws were used to fell the trees, and bucking saws were used to cut felled trees into log lengths for the sawmill. [3] The two applications require slightly different designs: a felling saw has a narrower blade, allowing wedges to be more easily inserted, while a bucking saw has a wider blade, giving it more strength.

In January 1924, they were granted a patent for the hand saw, with the Michel Electric Hand Saw Company being established in June of that year. Despite attracting immediate ...
