60-589: A whipsaw , one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill , a Roman water-powered stone mill at Hierapolis , Asia Minor dating back to the 3rd century AD. Other water-powered mills followed and by the 11th century they were widespread in Spain and North Africa, the Middle East and Central Asia, and in the next few centuries, spread across Europe. The circular motion of

90-415: A term used in many mechanical applications). Generally, only the saw was powered, and the logs had to be loaded and moved by hand. An early improvement was the development of a movable carriage, also water powered, to move the log steadily through the saw blade. A type of sawmill without a crank is known from Germany called "knock and drop" or simply "drop" -mills. In these drop sawmills, the frame carrying

120-608: Is a former village in Northumberland County, New Brunswick , Canada. It is now part of the rural community of Miramichi River Valley . It is located on the Southwest Miramichi River approximately 40 km (25 mi) southwest of Miramichi . The first post office opened in the area in 1842, under the community name "Decantillon's"; the area known as The Forks was also serviced by this post office. In 1847, these areas collectively became known as Blackville, as

150-647: Is home to a single financial institution, Blackville Credit Union. It is the oldest of its kind in New Brunswick. Blackville School , grades K–12, is a public school in the community. This is the only grade school in Blackville, with students occasionally transporting to other Miramichi schools instead (Such as Miramichi Valley High School ). Sawmill Before the invention of the sawmill, boards were made in various manual ways, either rived (split) and planed , hewn , or more often hand sawn by two men with

180-590: Is much like those of hundreds of years ago: a log enters on one end and dimensional lumber exits on the other end. The Hierapolis sawmill , a water-powered stone sawmill at Hierapolis , Asia Minor (modern-day Turkey , then part of the Roman Empire ), dating to the second half of the 3rd century, is the earliest known sawmill. It also incorporates a crank and connecting rod mechanism. Water-powered stone sawmills working with cranks and connecting rods, but without gear train , are archaeologically attested for

210-526: Is the small portable sawmill for personal or even professional use. Many different models have emerged with different designs and functions. They are especially suitable for producing limited volumes of boards, or specialty milling such as oversized timber. Portable sawmills have gained popularity for the convenience of bringing the sawmill to the logs and milling lumber in remote locations. Some remote communities that have experienced natural disasters have used portable sawmills to rebuild their communities out of

240-507: The Christian saint Gregory of Nyssa from Anatolia around 370–390 AD, demonstrating a diversified use of water-power in many parts of the Roman Empire . Sawmills later became widespread in medieval Europe , as one was sketched by Villard de Honnecourt in c. 1225–1235. They are claimed to have been introduced to Madeira following its discovery in c. 1420 and spread widely in Europe in

270-687: The Pee Dee River from as far as the edge of the Appalachian Mountains in North Carolina . A restoration project for Sturgeon's Mill in Northern California is underway, restoring one of the last steam-powered lumber mills still using its original equipment. In the twentieth century the introduction of electricity and high technology furthered this process, and now most sawmills are massive and expensive facilities in which most aspects of

300-464: The Pee Dee River from the Appalachian Mountains . In the 20th century the introduction of electricity and high technology furthered this process, and now most sawmills are massive and expensive facilities in which most aspects of the work are computerized. Besides the sawn timber, use is made of all the by-products including sawdust , bark , woodchips , and wood pellets , creating a diverse offering of forest products . A sawmill's basic operation

330-636: The sawfiler . Sawfilers were highly skilled in metalworking. Their main job was to set and sharpen teeth. The craft also involved learning how to hammer a saw, whereby a saw is deformed with a hammer and anvil to counteract the forces of heat and cutting. Modern circular saw blades have replaceable teeth, but still need to be hammered. The introduction of steam power in the 19th century created many new possibilities for mills. Availability of railroad transportation for logs and lumber encouraged building of rail mills away from navigable water. Steam powered sawmills could be far more mechanized. Scrap lumber from

360-399: The 16th century. Prior to the invention of the sawmill, boards were rived (split) and planed, or more often sawn by two men with a whipsaw , using saddleblocks to hold the log, and a saw pit for the pitman who worked below. Sawing was slow, and required strong and hearty men. The topsawer had to be the stronger of the two because the saw was pulled in turn by each man, and the lower had

390-627: The 6th century at the Byzantine cities Gerasa (in Asia Minor) and Ephesus (in Syria ). The earliest literary reference to a working sawmill comes from a Roman poet, Ausonius , who wrote a topographical poem about the river Moselle in Germany in the late 4th century AD. At one point in the poem, he describes the shrieking sound of a watermill cutting marble . Marble sawmills also seem to be indicated by

420-534: The Miramichi River Valley Rural Community's elections for mayor, three at-large councillors, and the Ward 3 councillor. The community is within the federal electoral district of Miramichi-Grand Lake , and within the provincial electoral district of Southwest Miramichi-Bay du Vin . The mayors of Blackville during its time as an incorporated village from 1967 to 2022 included: Blackville's economy

450-433: The advantage of gravity. The topsawyer also had to guide the saw so that the board was of even thickness. This was often done by following a chalkline. Early sawmills simply adapted the whipsaw to mechanical power, generally driven by a water wheel to speed up the process. The circular motion of the wheel was changed to back-and-forth motion of the saw blade by a connecting rod known as a pitman arm (thus introducing

480-568: The area was the largest population centre in the Parish of Blackville . The parish, created in 1830 when it was partitioned from the Parish of Ludlow , had been named in honour of William Black , the acting governor of the colony of New Brunswick from 1829 to 1831. Blackville was first incorporated as a village in 1967, annexing the neighbouring communities of Underhill and Breadalbane later that year. On January 1, 2023, Blackville amalgamated with all or part of eight local service districts to form

510-580: The availability of ships transporting cargoes of logs to the sawmill and cargoes of lumber from the sawmill. The next improvement was the use of circular saw blades, perhaps invented in England in the late 18th century, but perhaps in 17th-century Netherlands. Soon thereafter, millers used gangsaws, which added additional blades so that a log would be reduced to boards in one quick step. Circular saw blades were extremely expensive and highly subject to damage by overheating or dirty logs. A new kind of technician arose,

540-582: The development of steam power in the 19th century, a much greater degree of mechanisation was possible. Scrap lumber from the mill provided a source of fuel for firing the boiler. The arrival of railroads meant that logs could be transported to mills rather than mills being built beside navigable waterways. By 1900, the largest sawmill in the world was operated by the Atlantic Coast Lumber Company in Georgetown, South Carolina, using logs floated down

570-495: The fallen trees. Technology has changed sawmill operations significantly in recent years, emphasizing increasing profits through waste minimization and increased energy efficiency as well as improving operator safety. The once-ubiquitous rusty, steel conical sawdust burners have for the most part vanished, as the sawdust and other mill waste is now processed into particleboard and related products, or used to heat wood-drying kilns . Co-generation facilities will produce power for

600-411: The forest, where a temporary shelter was built, and the logs were skidded to the nearby mill by horse or ox teams, often when there was some snow to provide lubrication. As mills grew larger, they were usually established in more permanent facilities on a river, and the logs were floated down to them by log drivers . Sawmills built on navigable rivers, lakes, or estuaries were called cargo mills because of

630-441: The growth of a frontier community. The Dutch windmill owner Cornelis Corneliszoon van Uitgeest invented in 1594 the wind-powered sawmill, which made the conversion of log timber into planks 30 times faster than before. His wind-powered sawmill used a crankshaft to convert a windmill 's circular motion into a back-and-forward motion powering the saw, and was granted a patent for the technique. Early mills had been taken to

660-536: The mill provided a ready fuel source for firing the boiler. Efficiency was increased, but the capital cost of a new mill increased dramatically as well. In addition, the use of steam or gasoline-powered traction engines also allowed the entire sawmill to be mobile. By 1900, the largest sawmill in the world was operated by the Atlantic Lumber Company in Georgetown , South Carolina, using logs floated down

690-498: The new incorporated rural community of Miramichi River Valley. Blackville remains in official use. In the 2021 Census of Population conducted by Statistics Canada , Blackville had a population of 914 living in 394 of its 446 total private dwellings, a change of -4.6% from its 2016 population of 958 . With a land area of 20.97 km (8.10 sq mi), it had a population density of 43.6/km (112.9/sq mi) in 2021. Blackville residents are able to cast votes in

720-478: The operation and may also feed superfluous energy onto the grid. While the bark may be ground for landscaping barkdust , it may also be burned for heat. Sawdust may make particle board or be pressed into wood pellets for pellet stoves. The larger pieces of wood that will not make lumber are chipped into wood chips and provide a source of supply for paper mills. Wood by-products of the mills will also make oriented strand board (OSB) paneling for building construction,

780-600: The saw blade is knocked upwards by cams as the shaft turns. These cams are let into the shaft on which the waterwheel sits. When the frame carrying the saw blade is in the topmost position it drops by its own weight, making a loud knocking noise, and in so doing it cuts the trunk. A small mill such as this would be the center of many rural communities in wood-exporting regions such as the Baltic countries and Canada . The output of such mills would be quite low, perhaps only 500 boards per day. They would also generally only operate during

810-465: The wheel was converted to a reciprocating motion at the saw blade. Generally, only the saw was powered, and the logs had to be loaded and moved by hand. An early improvement was the development of a movable carriage, also water powered, to move the log steadily through the saw blade. By the time of the Industrial Revolution in the 18th century, the circular saw blade had been invented, and with

840-581: The winter, the peak logging season. In the United States , the sawmill was introduced soon after the colonisation of Virginia by recruiting skilled men from Hamburg . Later the metal parts were obtained from the Netherlands, where the technology was far ahead of that in England , where the sawmill remained largely unknown until the late 18th century. The arrival of a sawmill was a large and stimulative step in

870-440: The work is computerized . The cost of a new facility with 4,700-cubic-metre-per-day (2-million- board-foot -per- day ) capacity is up to CAN$ 120,000,000. A modern operation will produce between 240,000 to 1,650,000 cubic metres (100 to 700 million board feet) annually. Small gasoline-powered sawmills run by local entrepreneurs served many communities in the early twentieth century, and specialty markets still today. A trend

900-406: Was once tied to the forest industry. A large sawmill that employed 200 workers had been operated in the village by industrial conglomerate UPM Kymmene , but it closed in 2007 as a result of economic pressures. According to the 2016 Census, Blackville citizens had a median income of $ 30,816 for individuals, and $ 62,976 for households in 2015. Blackville's unemployment rate was 21.9%. Blackville
