Millers Falls Hand Tools' title='Millers Falls Hand Tools' />Hand powered drilling tools and machines For most of human history, drilling a hole into whatever chosen material required an extensive amount of time and effort. The first crude drilling tool was the awl, a sharp stone, flint, copper or bone point that could be attached to a piece of wood. The awl was pressed against an object and then rotated by hand, much like a present day screwdriver. An alternative primitive method was the hand drill or shaft drill, where a stick was rotated between the palms. Abrasives such as sand could be used simultaneously to make this drilling method more effective. Kanye West Vh1 Storytellers Full. These were extremely labour intensive tasks, especially when the material that had to be drilled was hardy, like stone. Ps 1131 Software Workshops. Millers Falls Hand Tools' title='Millers Falls Hand Tools' />In his study of ancient stone working technology see sources, Denys Stocks came to the conclusion that even with a bronze drill bit it took up to 5 hours to drill a tiny hole 1 centimetre deep in a hard stone like quartz. Drilling holes into hard stone was commonplace in ancient times, for example in construction work and the making of necklaces and bracelets, so it is not surprising that our forefathers were investigating more efficient drilling methods with fervour. Strap drills, bow drills and pump drills. The first step toward mechanisation was the strap drill also known as cord drill or thong drill, which offered an increased rotation speed of the drill bit. The tool consisted of a drill bit attached to a longer wooden shaft, which was rotated by wrapping a cord or leather strap once around it and holding the ends with ones hands by pulling in one direction and then the other, the shaft spun and drilled into the material. The top of the shaft rotated freely in a mouthpiece which was held between the users teeth to exert more downward pressure. The tool was also used to make fire, which is the reason why it is also known as a fire drill.

Most have been cleaned and are ready to use except for sharpening and a final. The strap drill was widely used, but was eventually superseded by the bow drill, which appeared at least 6,0. Egypt. Based on the cord drill, the difference was that the cord or strap, again wrapped once around the shaft, was tied to a bow. Holding the drill vertically and the bow horizontally, the user then moved the bow backward and forward much like a cellist to revolve the shaft picture on the right, by Rudolf Hommel. The bow drill possessed two advantages over the strap drill the shaft could be rotated at a higher speed, and as only one hand was needed to handle the bow, downward pressure could be exerted with the other hand instead of the mouth. Smaller bow drills were also used for dental care. The tool could be made from a few pieces of wood, a piece of string and a drill bit. A later improvement to the bow drill was the pump drill, which appeared in Roman times picture on the left, source. It is similarly operated, except it functions by means of a downward instead of sideward movement. Sandor Nagyszalancy explains how it works in his book Tools Rare and Ingenious Pump drills get their name from the way theyre used. Pumping the crossbar up and down causes a string to wind and unwind at the shaft, thus spinning a pointed bit thats fastened to the end of the shaft back and forth. The thick, rounded section just above the bit serves as a small flywheel to keep the spinning motion going. Once more, the pump drill offered superior rotating speeds and more downward pressure. All these ancient drills were used in conjunction with a sharp drill point or with the help of abrasives especially when drilling through stone. Pump and bow drills which could not work without ropes and knots are among the most successful tools ever made.

The Chinese were especially keen on the above drilling tools. They relied on bow, pump and thong drills up until the beginning of the twentieth century and never developed any of the drilling tools that will be discussed further below. Rudolf Hommel photographed some of the Chinese drilling devices in his book China at work. Chinese shipbuilders employed a larger version of the thong drill which was operated by two to three people. The Last Poets This Is Madness Rarity on this page. It was used for drilling the preliminary holes for the iron spikes which they utilized in ship construction. Henry Chapman Mercer describes the tool in his 1. Ancient Carpenters Tools To work the apparatus, the thong is twisted around the spindle, whereupon one man holds down the pivot handle, thereby pressing down the drill bit into the wood, while two other man, each grasping the thong by one of its terminal handles, or one man holding a thong handle in each hand and pulling the thong to and fro, cause the drill to twirl back and forth, as with the common bow drill. The thong drill. Picture from China at work by Rudolf Hommel. According to some historians, the Egyptians also made use of large bow drills operated by several people to make large holes and to hollow out spaces in their pyramids. Bronze hollow tubes of about 1. Even larger holes could have been made by performing several drilling operations right next to each other, in a circular form. The core drill allows for larger holes without sacrificing drilling speed, because much less material has to be reduced to powder. Denys Stocks conducted real life experiments to see if this method could work, and succeeded. The results indicate that two drillers were required to push and pull a large bow, while a third person balanced a stone drill cap on top of the shaft to exert downward pressure. Stocks achieved a drilling speed of 2 centimetres per hour in granite stone, and thinks the ancient Egyptians could have reached speeds of 1. Whether or not the ancient Egyptians applied this technique remains open to debate, though. Archaeological remains of these tools have never been found, and unlike smaller drilling operations common bow drills, stone drills to hollow out granite vases these large scale operations were only vaguely alluded to in wall paintings. Augers, gimlets and reamers. Another very important invention from Roman times was the T shaped auger and the much smaller gimlet. Basically a long drill bit with a pair of wooden handles for rotating it. The tool looks a like an oversized corkscrew picture on the left, source. Augers were used to drill large andor deep holes in wood, for which the bow or pump drill was not very useful. They were applied by shipbuilders, bridgebuilders, millwrights, wheelwrights and the like. In the Middle Ages augers were sometimes equipped with a breastplate on top for more drilling pressure the user could rest the entire weight of his body on the pad. However, operating them was a tedious task. The Roman writer Vitruvius noted that the difficulty of the boring increased exponentially with the diameter of the hole. Apart from drilling holes, an auger was also used for reaming enlarging an already existing hole.
