Hand Saws Hand Saws Have Evolved to fill Many Niches and Cutting Styles
Source: https://www.garagetooladvisor.com/hand-tools/different-types-of-saws-and-their-uses/ Hand Saws Hand saws have evolved to fill many niches and cutting styles. Some saws are general purpose tools, such as the traditional hand saw, while others were designed for specific applications, such as the keyhole saw. No tool collection is complete without at least one of each of these, while practical craftsmen may only purchase the tools which fit their individual usage patterns, such as framing or trim. Back Saw A back saw is a relatively short saw with a narrow blade that is reinforced along the upper edge, giving it the name. Back saws are commonly used with miter boxes and in other applications which require a consistently fine, straight cut. Back saws may also be called miter saws or tenon saws, depending on saw design, intended use, and region. Bow Saw Another type of crosscut saw, the bow saw is more at home outdoors than inside. It uses a relatively long blade with numerous crosscut teeth designed to remove material while pushing and pulling. Bow saws are used for trimming trees, pruning, and cutting logs, but may be used for other rough cuts as well. Coping Saw With a thin, narrow blade, the coping saw is ideal for trim work, scrolling, and any other cutting which requires precision and intricate cuts. Coping saws can be used to cut a wide variety of materials, and can be found in the toolkits of everyone from carpenters and plumbers to toy and furniture makers. Crosscut Saw Designed specifically for rough cutting wood, a crosscut saw has a comparatively thick blade, with large, beveled teeth. -
Tula Adze Download
Australian Artefact Fact Sheet Tula adze Tula adzed dish Tula adze slug Tula adze slug Where? Across most of Australia with a focus on Central and Western Australia. The name tula or tuhla comes from the Wangkangurru people of the Simpson Desert. What? The tula adze is a hafted flaked stone tool mostly used for wood working (scraping, adzing and hardwood such as Acacias and Eucalypts. They were also used to butcher animals and to chop plants. When they are used to adze hard wood they blunt quickly and were then resharpened repeatedly by knocking off small flakes along the working edge. In archaeological sites they are usually found as exhausted slugs that have been removed from their hafting, discarded and then replaced. When? Tools such as tulas are rare in archaeological sites and especially places that can be dated. This has meant that there are small numbers that have been securely dated. The oldest dated tula adzes come from rockshelters in the Hamersley Ranges near Newman and Packsaddle dated to between 3,700 and 3,500 years ago. How? Tula adzes are made by flaking a core. They have a wide flat top (platform) that allows easy hafting and they have a curved shaped back (convex). The adzes were usually hafted into the ends of a wooden stick or spear thrower encasing the end of the stick/spear thrower in a resin glue made from spinifex or grevillea resin, kangaroo poo and sand. It took about two tulas to make a boomerang and an undecordated spear thrower would take about eight hours to make with a tula adze. -
Active Extensional Faults in the Central-Eastern Iberian Chain, Spain

ISSN (online): 1886-7995 www.ucm.es/info/estratig/journal.htm Journal of Iberian Geology 38 (1) 2012: 127-144 http://dx.doi.org/10.5209/rev_JIGE.2012.v38.n1.39209 Active extensional faults in the central-eastern Iberian Chain, Spain Fallas activas extensionales en la Cordillera Ibérica centro-oriental J.L. Simón*, L.E. Arlegui, P. Lafuente, C.L. Liesa Dpt. Ciencias de la Tierra, Facultad de Ciencias, Universidad de Zaragoza, c/ Pedro Cerbuna 12, E-50009 Zaragoza, Spain [email protected], [email protected], [email protected], [email protected] *Corresponding author Received: 27/06/2011 / Accepted: 29/02/2012 Abstract Among the conspicuous extensional structures that accommodate the onshore deformation of the Valencia Trough at the central- eastern Iberian Chain, a number of large faults show evidence of activity during Pleistocene times. At the eastern boundary of the Jiloca graben, the Concud fault has moved since mid Pliocene times at an average rate of 0.07-0.08 mm/y, while rates from 0.08 to 0.33 mm/y have been calculated using distinct stratigraphic markers of Middle to Late Pleistocene age. A total of nine paleoseisms associated to this fault have been identified between 74.5 and 15 ka BP, with interseismic periods ranging from 4 to 11 ka, estimated coseismic displacements from 0.6 to 2.7 m, and potential magnitudes close to 6.8. The other master faults of the Jiloca graben (Ca- lamocha and Sierra Palomera faults) have also evidence of Pliocene to Late Pleistocene displacement, with average slip rates of 0.06 and 0.11-0.15 mm/y, respectively. -

The Bow and Arrow in the Book of Mormon
The Bow and Arrow in the Book of Mormon William J. Hamblin The distinctive characteristic of missile weapons used in combat is that a warrior throws or propels them to injure enemies at a distance.1 The great variety of missiles invented during the thousands of years of recorded warfare can be divided into four major technological categories, according to the means of propulsion. The simplest, including javelins and stones, is propelled by unaided human muscles. The second technological category — which uses mechanical devices to multiply, store, and transfer limited human energy, giving missiles greater range and power — includes bows and slings. Beginning in China in the late twelfth century and reaching Western Europe by the fourteenth century, the development of gunpowder as a missile propellant created the third category. In the twentieth century, liquid fuels and engines have led to the development of aircraft and modern ballistic missiles, the fourth category. Before gunpowder weapons, all missiles had fundamental limitations on range and effectiveness due to the lack of energy sources other than human muscles and simple mechanical power. The Book of Mormon mentions only early forms of pregunpowder missile weapons. The major military advantage of missile weapons is that they allow a soldier to injure his enemy from a distance, thereby leaving the soldier relatively safe from counterattacks with melee weapons. But missile weapons also have some signicant disadvantages. First, a missile weapon can be used only once: when a javelin or arrow has been cast, it generally cannot be used again. (Of course, a soldier may carry more than one javelin or arrow.) Second, control over a missile weapon tends to be limited; once a soldier casts a missile, he has no further control over the direction it will take. -
