Cast VS Forge Steel
Cast VS Forge Steel
Forging and casting are two of many ways to make metal parts. Whether you’re doing this, or welding, or machining, each method has its own pros and cons. Here’s an explanation of the differences between these processes.
Selecting A Hammer
Selecting A Hammer
The most expensive hammer you can buy is the cheap hammer which can become a dangerous liability in its short lifespan. A quality hammer can be a lifetime investment. The first consideration of anyone who knows their hammer is balance. The proper head-to-handle weight distribution is very important. When a hammer has good balance, it seems to swing itself.
Wheelbarrow
Wheelbarrow
A wheelbarrow is a carrier, usually having only one wheel, consisting of a tray bolted to two handles and two legs. While known mostly as a device for carrying small loads for the household gardener, a wheelbarrow is often also used in construction and industry for carrying larger loads.
ABS Material
ABS Material
What is ABS Material? ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic resin commonly used for injection molding applications. ABS Plastic is a copolymer of Acrylonitrile, Butadiene, and Styrene, and generally possess medium strength and performance at medium cost. ABS is considered the best of the styrene family. It is tough, hard and rigid and has good chemical resistance and dimensional stability.

Get the Job Done with Correct Fastener- Nails
Common Nails: Used for most medium to heavy construction work, this type of nail has a thick head and can be driven into tough materials. Common nails are made from wire and cut to the proper length and are available in sizes 2d through 60d ( Penny size, almost always referred to as "d".) Box Nails: Lighter and smaller in diameter than common nails, box nails are designed for light construction and household use. Finishing Nails: Finishing nails are lighter than common nails and have a small head. They are often used for installing paneling and trim where you do not want the nail head to show. Roofing Nails: Usually galvanized, roofing nails have a much larger head than common nails. This helps to prevent damage to asphalt shingles. Drywall Nails: Nails made for drywall installation are often ringed and have an indented head. Annular-ring nails have sharp ridges all along the nail shaft, providing greater holding power. Masonry Nails: There are three types of masonry nails designed for use with concrete and concrete block: round, square, and fluted. Masonry nails should not be used where high strength is required. Fastening to brick, stone, or reinforced concrete should be made with screws or lag bolts. Tacks: Available in both round and cut forms, tacks are used to hold carpet or fabric to wood. Upholstery tacks have decorative heads. Corrugated Fasteners: Corrugated fasteners, also called wiggly nails, are used for light-duty joints where strength is not important. The fasteners are set at right angles to the joint.
Different Types of Wood
Different Types of Wood
Choose the type of wood you use for your building construction project based on the different qualities and strengths of the specific wood. Some varieties of wood are much more suitable than others are for building and wood construction projects. Wood naturally creates different solutions for different spaces. Some building wood can hold heavy loads while some cannot. Pine is a variety of softwood that is very easy to work with. It is very easy to carve and drill. Pine usually has a light yellow coloring that can really brighten any interior. After it has been sealed, pinewood is very easy to stain if you want it to be slightly darker. However, many woodworkers simply seal the wood and apply a clear finish. Cedar is another softwood that is very easy to use. It is well known for its warm, red tones and lovely aromatic note. It is also highly resilient to the elements. This makes it an excellent option for outdoor furniture. It is also extremely useful for chests or wardrobes that would be holding clothing that is not used often. The wood itself naturally wards off moths. Redwood is also very resistant to moisture, so it is a great choice for outdoor furniture as well. It is relatively soft and is easy to work with. It has a slight reddish hue. You can use stains and paint on redwood, but it is such a nice color that many woodworkers use a water repellant with mildewcide for outdoor furniture. Cherry is a hardwood that is slightly more difficult to work with. However, it is considered a softer hardwood. It has a warmer reddish tone that can complement a lighter interior. Maple has 2 varieties, a harder variety and a softer variety. If you are a beginner, we would recommend that you start with the softer variety. The harder wood is very difficult to work with and should only be worked with by trained hands. Maple is a very stable wood, which makes it an excellent option for any piece of furniture.
What is Rubber ?
What is Rubber ?
No one is ignorant of rubber and rubber products. Rubber has, in fact, become an indispensable part of everyone's life. So, lets know about the different types of rubber used for making industrial rubber goods as well as consumer and daily use products. What is Rubber? Technically speaking, rubber is a natural polymer of Isoprene (usually cis-1,4-polyisoprene). It is hydrocarbon polymer occurring as milky latex in the sap of various plants and can also be made synthetically. A small percentage (about 5%) of other materials like proteins, fatty acids, resins and inorganic materials (salts) are also present in natural rubber. Rubber, as mentioned earlier too, can also be made artificially or synthetically. The type of rubber which is produced artificially is called synthetic rubber. In simple terms, rubber can be defined as a sticky, elastic solid which is produced from a milky liquid known as latex obtained from various types of rubber trees. Different Types of Rubber There are basically two broad categories into which the rubber types can be placed. These are- Natural Rubber and Synthetic Rubber. Sometimes vulcanized rubber is also taken to be a type of rubber. Lets know about all these types of rubber. Natural Rubber The elastic material which is obtained from the latex sap of trees is called natural rubber. Natural rubber can be vulcanized and finished into a various types of rubber products. Various types of tropical and sub-tropical trees in the regions of Amazon, South East Asia and Africa produce the milky fluid latex that are in the form of latex tubes. The rubber molecules present in these latex tubes are made up of 5 carbon and 8 hydrogen atoms. A large number of these rubber molecules are joined with each other to form long, chain-like structure. This chain of rubber molecules is called polymers that gives rubber its property of elasticity. Synthetic Rubber Any kind of artificial elastomer (a polymer) is called synthetic rubber. An elastomer can be defined as a material having the property of elasticity. Thus, the type of rubber made from chemicals to act as the substitute for natural rubber is the synthetic rubber. There are various types of polymers used for making synthetic rubber types. Due to this, different types of synthetic rubbers have different properties that are tailored for specific needs of rubber products industries. To have an idea about these different synthetic rubbers, read about the Types of Synthetic Rubber
Copper
Copper
Copper is a chemical element with the symbol Cu. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC, the first metal to be cast into a shape in a mold, c. 4000 BC and the first metal to be purposefully alloyed with another metal, tin, to create bronze, c. 3500 BC. Copper used in buildings, usually for roofing, oxidizes to form a green verdigris (or patina). Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives.
