What is the name of the inventor of the chainsaw?

Korin - Dragon Ball FanartSaws are the oldest working tools and artisan tools in human civilization, number 2 after sharp-edged knives. There are many archaeological objects used by ancient humans in the form of saws that are still being studied by experts and we can also see in museums. In this article we discuss more about the interesting history of this saw workpiece. Ancient buildings such as the Pyramids in Egypt or the Borobudur temple in Magelang which are currently tourist attractions, may not be able to be built without saw carpentry technology. As a must-have handyman tool, the chainsaw was originally shaped like jagged materials such as flint, obsidian, sea shells, and ancient shark teeth. A saw is a handyman tool that has been used to cut various materials, including to punish humans (death by sawing). The saw model has been found in many contexts throughout Egyptian history. In ancient Egyptian sites there are indeed many illustrations of carpenter's tomb walls at work showing the sizes and uses of different types of saws.

Egyptian saws were originally serrated, hardened copper that cut through both pulling and pushing.

In ancient Egypt, open (frameless) saws made of copper were documented as far back as the Early Dynastic Period, circa 3100-2,686 BC. Many copper saws were found in the tomb of No. 3471 dating from the reign of the king Pharaoh Djer in the 31st century BC. Djer (or Zer or Sekhty) is considered the third pharaoh of ancient Egypt's First Dynasty in modern Egyptology. He lived around the middle of the thirty-first century BC and reigned c. 40 years. The forearm of the mummy of Djer or his wife was discovered by Flinders Petrie, a British archaeological researcher. Djer, Egypt is experiencing a lot of urban infrastructure development and carpentry. Pharaoh Djer is also known as the first ancient era leader who had an interest in handicrafts, science and building tools. In that era, saws were also used to cut elephant tusks and as a must-have handyman tool. Egyptian saws were originally serrated, hardened copper that cut through both pulling and pushing. As the saw developed, the teeth were raked to be cut by pulling only and fixed with the teeth protruding only on one side, rather than the modern way with alternating sets. Saws were also made of bronze and later iron. In the Iron Age, frame saws were developed to hold thin blades under tension.

Lu Ban was a Chinese Chinese construction engineer, inventor, and carpenter during the Zhou dynasty.

The earliest known sawmills are the Roman Hierapolis sawmill from the third century C.E. and for sawing stone. In East Asia, according to myths, legends and ancient Chinese literature, the hand saw was invented by a craftsman named Lu Ban who is thought to have lived from the 507-444 BC era. Lu Ban was a Chinese Chinese construction engineer, inventor, and carpenter during the Zhou dynasty. Due to the quality of his craftsmanship and service, the emperors of ancient China honored him as the Chinese God (Protector) of builders, craftsmen and field contractors. Although his real name during his time as a commoner was Gongshu Yizhi, he was also referred to as Gongshu Ban or Pan. In Chinese mythology, it is very rare for an ordinary human being to be made a god by the Chinese emperor, of course this is intended as the highest award that the Chinese emperor can give to a craftsman who is credited with building his empire's infrastructure and successfully finding craftsman tools such as saws. Lu Ban was originally an indifferent student until his love of learning was ignited after studying with an ancient Chinese scholar named Zi Xia. He then learned woodworking from a senior carpenter named Bao Laodong. The huge demand for his work should have forced him to make his own tools or repair some of the carpenter's tools - saws, squares, planers, drills, spades, and ink-marking tools - in order to complete many of his projects more quickly. His wife is also considered the inventor of the folding umbrella who wanted Lu Ban to focus on working as a handyman despite the bad weather.

But the Greek Goddess Athena intervened and turned Talos/Perdix into a partridge to save his life.

In western Asia Minor culture and Greek mythology, the god of innovation and invention is named Talos, the nephew of the god of craftsmanship named Daedalus. Ancient Greek life and civilization also saw the saw as a symbol of the essential tools of carpentry and innovation. Talos, also known as Perdix or Attalus, Daedalus' nephew was inspired to make chainsaws after seeing the spinal structure of fish. The hand saw made from fish bones allowed Talos to work smarter in making crafts and inventions that became the center of attention of the Greek gods. So jealous of Daedalus who is known as the god of carpentry and technicians, he tries to kill his nephew Talos. But the Greek Goddess Athena intervened and turned Talos/Perdix into a partridge to save his life. According to Ovid, a Roman poet who lived during the reign of Augustus of the Roman empire, the partridge was then able to live a long life and witness the death and burial of Icarus, son of the artisan god Daedalus. In reality and archaeological facts themselves, the oldest saw in human civilization is actually even older. These saws date back to prehistoric times and most likely evolved from Neolithic stone or bone tools. The design form and identity of work tools such as saws, axes, hammers, and chisels are clearly made up of more than 4. 000 years ago. Modern hacksaw saw blades are also popularly used in the Bronze Age of the ancient Greek Akrotiri civilization, the late C Cycladian period, there are also a lot of them found. Greek woodworkers using a hand saw made of bronze metal in the 17th century BC.

Cycladic Bronze Age settlement on the Greek volcanic island of Santorini (Thera). This ancient Greek settlement was destroyed in the eruption of Mount Theran in 1628 BC and is buried in volcanic ash, which preserves the remains of fine frescoes and many objects and works of art and ancient carpentry tools. The settlement has been suggested as a possible inspiration for Plato's story of Atlantis. After mankind learned how to use practical ferrous metal materials, iron became the material of choice for all types of saw blades; some cultures have studied how to harden surfaces by sprinkling melted salt and carbon mud ("box hardening" or "hardening"), prolonging the life and sharpness of the blade. Steel, made of iron with a medium carbon content and hardened by cooling hot steel in water, has been in use since 1200 BC. By the end of the 17th century the manufacture of European artisan tools was centered in Germany, (Land of Bergisches) in London, and the Midlands of England. The Germans in mainland Europe at that time were still backward compared to the British, but Germany had a center for artisan craftsmen whose rates were cheaper. The Germans then imitated the British saw design and industrial technology in the era of the first industrial revolution. Most saw blades at that time were indeed made of alloy steel (iron was carbonized and reforged by a different method). In the mid-18th century, superior forms of completely melted steel ("crucible cast") began to be made in Sheffield, England, and this quickly became the preferred material, due to the more stable properties of the casting melt, its hardness, flexibility and flexibility. and its ability to be finely polished. Although Germany later became the center of the mass saw industry in Europe, the small saw industry persisted in London and Birmingham, but in the 1820s the sawmaking industry grew rapidly and became increasingly concentrated in Sheffield, which remains the largest production center, with over 50 % national chainsaw maker.

American industry began to catch up in the last decades of this century, due to superior mechanization and better demand and marketing. In the era of the second industrial revolution, the United States became a large market for craftsman tools, so the government decided to impose high tariffs on imports of European-made craftsman tools. The highly productive saw industry also continues with its own machine technology in Germany and France. Early European saws were made from heated sheets of iron or steel, manufactured by being flattened by several people simultaneously hammering an anvil (Barley ibid p11) After cooling, the teeth were punched one by one with a die, the size of which varied with the size of the saw. The sawtooth can be sharpened with a triangular angle file of a suitable size, and fixed with a hammer or wrestler (Moxon, ibid). In the mid-18th century, metal winding was common, power for the coils was first supplied by water, and was further increased in the early 19th century by steam engines. The chainsaw manufacturing industry is also gradually adopting all automated mechanical processes, including the essential grinding of "thin back" saw plates by fractions of an inch, which helps the saw pass through the kerf without binding (Moxon, ibid, p95). The use of steel adds to the need to harden and soften the saw plate, to grind it flat, to hammer it with a hand hammer and ensure the saw is resistant to bending, and remains polished (Barley ibid pp5-22). Most hand saws manufactured today are manufactured entirely without the intervention of a human operator, with steel plates provided ready to be rolled and tensioned before being cut and pressed into shape with a metal laser cutting machine. Teeth are shaped and sharpened by grinding and fire-hardening to remove (and actually prevent) sharpening once they have become blunt.

At present, chainsaws and their eyes are divided into 5 general types, namely; back-and-forth cutting saws or hack saws which are also divided into machine variations and manual hand saws, serkel circular saws used for manual and automatic manual work such as pipe cutting fly cutting, wire saws such as scroll saw blades, chain saws for cutting wood, and the most popular in the factory, namely the band saw or band saw is an electric saw working tool with a long continuous blade. These band saws are sharp bladed and consist of a continuous toothed metal band stretched between two or more wheels for cutting the work material. This band sawing machine is popular because the same machine and even the saw blade can be used in woodworking as well as metalworking. In addition to its ability to cut a variety of materials, this Bensaw band saw machine is also in demand because of its uniformly uniform cutting results, ease of use because it generally rotates and presses automatic materials as well as the ability to cut irregular or curved shapes such as a jigsaw. If the saw blade is suddenly damaged, it is usually caused by improper interaction between the human operator, the saw engine, the cutting material, the material clamping vise and the saw blade. Of course, there are 5 contributing factors, namely; installation errors that are too tight, the saw blade material does not match the object being cut, the speed setting and machine feeding is not correct, and material debris that erodes the back of the saw blade causing cracks and the last is the quality of the bandsaw blade is of low quality.

While technical problems such as wear and tear or premature tool failure can occur in any sawing operation, these problems can often be prevented by tool preparation and maintenance. Operators must understand the possible causes of failure and their causes in order to have effective countermeasures. You will also need to record and set the sawing parameters on the machine to suit the operator, as well as their extensive knowledge of applications. Sufficient and proven supply of coolant for the material to be cut is also necessary. In addition, material surfaces that are sanded, chipped, or very hard, or with very high material strengths, can cause service life problems if not adjusted properly. Since the hardness of the material is directly correlated with higher cutting temperatures, this can lead to premature wear. WHY IS THE INCH OR THE IMPERIAL MEASUREMENT SYSTEM STILL USED IN THE SPECIFICATION OF THE SAWS? Along with the technological innovation of the saw industry and wood processing, saws and handyman tools have changed towards mechanical machine processes. The idea of ​​mass sawing with a band saw began at least in 1809, when William Newberry received a British patent for the idea, however William Newberry never built his own saw mill because serkel saws were more popular at the time. In the 18th century, band saws were so large and expensive that they were impractical due to the inability to produce flexible, accurate and durable saw blades using the technology of the time. Constantly flexing the blade over the wheel causes the material or joint that welds it into a loop often to fail and fracture. Understandably in that era electric and gas welding technology has not been found.

Nearly 40 years passed before the Frenchwoman Anne Paulin Crepin invented the welding technique to overcome this hurdle. He filed a patent in 1846, and soon after sold the rights to use it to manufacturer A. Perin & Company of Paris. Combining this method with new steel alloys and advanced tempering techniques allowed Perin to manufacture the first modern saw blades. The first American band saw machine patent was granted to Benjamin Barker of Ellsworth, Maine, in January 1836. The first factory manufactured and commercially available in the US was by Paul Prybil's design. Electric hacksaws (with reciprocating blades) were once common in the metalworking industry, but hacksaws and cold saws have largely replaced them. Due to the popularity of the Band saw which is a cutting tool that can be equipped with material feeder flow technology such as modern conveyors. In the era of the first industrial revolution, chainsaws also played a major role in processing wood and metal materials. At that time, Britain controlled the world's industrial technology and had already imposed the imperial system of measurement or what we know as inches on all of its colonies, including colonies with large natural resources such as America, India and China. Even though Britain has now discarded the imperial system of measurement, its largest colony, the United States, is still stubbornly using this ancient unit of measurement. This is why chainsaws designed and sold today generally still use inches in their specifications.

Manufacturers of band saws that are guaranteed to have a high reputation such as LENOX, DoALL, Roentgen, NACHI, WIKUS certainly check the quality of the saw blades properly because they have better manufacturing technology and quality management. Broken welds at the joint point of the band saw blade are also unnatural premature damage to the band saw blade. This is due to an error in the welding process. If no consequential damage can be detected and the scalloped edges are subjected to normal wear and tear. This broken band saw blade can be repaired for further use by re-welding. To this day, a large number of manual hand finishes for quality chainsaws of various brands still reproduce the popular hand hacksaw designs of the 19th century. In the future, of course sawmill technology will also become increasingly digital and therefore more failure-safe: With predictive maintenance, the required wear-related repairs are systematically supported, thereby avoiding unplanned downtime.
