A tailstock, also known as a foot stock, [1] is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine. It is usually used to apply support to the longitudinal rotary axis of a workpiece being machined.
Modern cutting and scraping tools can also be coated with titanium nitride to improve wear characteristics. Woodturning tools must be sharpened more frequently than other edged woodworking tools to maintain a clean cut because the wood passes at great speed. Sharpening is usually accomplished with the aid of mechanical devices such as powered ...
Fieldstone is a naturally occurring type of stone, which lies at or near the surface of the Earth. Fieldstone is a nuisance for farmers seeking to expand their land under cultivation, but at some point it began to be used as a construction material. [1] [2] [3] Strictly speaking, it is stone collected from the surface of fields where it occurs ...
Dimension stone is natural stone or rock that has been selected and finished (e.g., trimmed, cut, drilled or ground) to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements.
Massive precut stone is also known as "prefabricated", or "pre-sized" stone is a modern method of building with load-bearing stone. [22] Precut stone is a DFMA construction method that uses large machine-cut stone blocks with precisely defined dimensions to rapidly assemble buildings in which stone is used as a major or the primary load-bearing ...
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 stone. A number of holes are then cut or drilled into the stone face along the scored line approximately 10 to 20 centimetres (3.9 to 7.9 in) apart.
Massive-precut stone is a modern stonemasonry method of building with load-bearing stone. [1] Precut stone is a DFMA construction method that uses large machine-cut dimension stone blocks with precisely defined dimensions to rapidly assemble buildings in which stone is used as a major or the sole load-bearing material.
Stone has been used for carving since ancient times for many reasons. Most types of stone are easier to find than metal ores, which have to be mined and smelted. Stone can be dug from the surface and carved with hand tools. Stone is more durable than wood, and carvings in stone last much longer than wooden artifacts.
