Piercing Saw
A piercing saw, also known as a jeweler's saw, is a type of saw commonly used in jewelry making on sheet metal. It is usually used on softer metals as the saw is delicate... Like a coping saw A coping saw is a type of bow saw used to cut intricate external shapes and interior cut-outs in woodworking or carpentry. It is widely used to cut moldings to create coped rather than mitre joints. It is occasionally used to create fretwork t ..., a piercing saw holds the blade in tension in a metal frame. As the fine blades frequently break, the frame is adjustable for blade length to allow the re-use of broken pieces. The frame throat size can range from .. Saw blades come in many different thicknesses and the choice of blade will depend on the material being sawn and nature of the work being done. For very fine delicate work, and for cutting very thin material use a finer blade, and for general purpose cutting a heavier blade. Saw blades have a range of sizes, from finest to coarse ...

Vallorbe Piercing Saw
Vallorbe () is a municipality in the district of Jura-Nord Vaudois in the canton of Vaud in Switzerland. History Vallorbe is first mentioned in 1139 as ''de valle urbanensi''. In 1148 it was mentioned as ''de valle urbe''. Geography Vallorbe has an area, , of . Of this area, or 22.1% is used for agricultural purposes, while or 66.7% is forested.

Jewelry Making
Jewellery design is the art or profession of designing and creating jewellery. This is one of civilization's earliest forms of decoration, dating back at least 7,000 years to the oldest known human societies in Indus Valley Civilization, Mesopotamia and Egypt. The art has taken many forms throughout the centuries, from the simple beadwork of ancient times to the sophisticated metalworking and gem cutting known in the modern day. Before an article of jewellery is created, design concepts are rendered followed by detailed technical drawings generated by a jewellery designer, a professional who is trained in the architectural and functional knowledge of materials, fabrication techniques, composition, wearability and market trends. Traditional hand-drawing and drafting methods are still utilized in designing jewellery, particularly at the conceptual stage. However, a shift is taking place to computer-aided design programs. Whereas the traditionally hand-illustrated jewel is typical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheet Metal
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous ( iron-based) metals and nonferrous metals such as aluminum or copper. Cop ...

Coping Saw
A coping saw is a type of bow saw used to cut intricate external shapes and interior cut-outs in woodworking or carpentry. It is widely used to cut moldings to create coped rather than mitre joints. It is occasionally used to create fretwork though it is not able to match a fretsaw in intricacy of cut, particularly in thin materials. Coping saw blades are always thicker and much coarser cutting than typical fretsaw blades and many others of its family members. Coping saws can however cut slight bends in the work, allowing circles to be cut if used carefully. History The coping saw was most likely invented in middle of the 16th century following innovations in metallurgy and with the invention of the spring-driven clock. Blades made of this material were strong and flexible thanks to rolling. This saw was also used in combination with so called ''Chevalet du Marqueterie'', invented in 1780, allowing to saw pack of veneers with one angle of cut. Construction A coping saw ...

Metalworking Hand Tools
Metalworking hand tools are hand tools that are used in the metalworking field. Hand tools are powered solely by the operator. Slapper Both metal and wood slappers are used for metalworking. Generally wood slappers are covered with a leather-face. Slappers can be used to shrink, contour, and planish (smooth) the panel without leaving rough marks to clean up. The salapper controls more surface with each blow than a hammer can and is very easy to use because it has the same angle of attack as a body hammer. This means the user does not need to change their arm and hand position when moving from hammer to slapper. The slapper can be far more effective than the hammer for shrinking because its leverage gives greater mechanical advantage over the rough spots. The slapper is great for working metal over a T-stake or for gouging and planishing. A good slapper can make radius bends and crowns quite well. A slapper works well with forming stakes and post dollies for lightly planishing and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jewellery Making
Jewellery ( UK) or jewelry ( U.S.) consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewellery may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal such as gold often combined with gemstones, has been the normal material for jewellery, but other materials such as glass, shells and other plant materials may be used. Jewellery is one of the oldest types of archaeological artefact – with 100,000-year-old beads made from '' Nassarius'' shells thought to be the oldest known jewellery.Study reveals 'oldest jewellery' , '' |
