Skateboard

A skateboard

A skateboard is a narrow wheeled platform (usually made of 7 ply maple), used for recreation and transportation. It was developed in the twentieth century by surfers, who first made them using rollerskates. They are typically part of western youth culture.

The skateboard has evolved a lot since the 50s, not only in shape but also materials used. Boards in the past were often in the shape of a surfboard, with little concave and had 1 ply of wood. The wheels were rather large compared to most of today's sizes and were usually made of clay. The trucks (axles) were also larger in size and less sturdy. Another difference is that the boards of the past had a very small nose, today's boards have almost identical noses and tails (the nose is usually a bit steeper however).



Composition

Deck - Skateboards are composed of several parts. The deck forms the body of the skateboard and provides a place to stand. It is covered with grip tape, which adds friction to its surface. Decks were originally a single piece of wood but are now usually made from seven plies of Canadian Hard Rock Maple glued together. The plies of maple are cross-laminated, meaning the direction of the wood grain alternates between plies. This is what gives the deck its strength. Sometimes other composite materials, such as fiberglass and Kevlar, are incorporated into deck construction, usually to lighten the board or increase its strength or rigidity. An average, all wood deck costs about $50 (US) while a deck including a material such as fiberglass in it can cost up to $70 or so (US).

The deck is normally 7 1/2 to 8 inches wide. Wider decks are better suited to vert skaters who need more control and stability while riding down the steep slopes and riding the transitions and walls of a halfpipe. Narrower decks are suited to street skaters who like to perform more technical tricks; a wide board often makes it awkward to pull off such maneuvers.

Skateboard decks are usually between 28 and 32.5 inches long. The longboard, a common variant of the skateboard, has a longer deck.

A skateboard truck

Trucks - Attached to the deck are two metal (usually aluminum) trucks, which connect to the wheels. The trucks are further composed of two parts. The top part of the truck is screwed to the deck and is called the baseplate, and beneath it is the hanger. Between the baseplate and the hanger are bushings, also rubbers or grommets, that provide the spring mechanism for turning the skateboard. The bushings cushion the truck when it turns. The stiffer the bushings, the more stable the skateboard. The softer the bushings, the easier it is to turn. A bolt called a kingpin holds these parts together.

Wheels - The wheels attach to each hanger. The wheels, usually made of polyurethane and come in nine different sizes and suit different types of skating. Larger sizes like 65-80mm roll faster which makes riding vert ramps easier. Smaller sizes like 52-55mm keep the board closer to the ground and are lighter which makes tricks easier to perform. For general cruising most users prefer larger, softer wheels.

Bearings - Inside each wheel are seven precision ball bearings, secured by a plastic "crown". Bearings are graded according to the ABEC scale, which goes from 1-9, in odd numbers. Higher numbers indicate that the bearing comforms to a higher degree of precision. The Best Bearings are Super Swiss Six, the balls inside the case of the bearing are made of ceramic clay instead of the traditional metal. It allows less friction and top speeds.

Risers - There are special products available to help raise the board away from the trucks and the ground. Risers are placed in between the underside of the deck and the truck. This rises the deck from the ground slightly, helping to avoid "wheel-bite",

Another reason riders install risers is that they evenly distribute impact force from the trucks to the deck, meaning less chance of the deck cracking under pressure. More risers will equal a higher board which also increases the "pop" a rider gets when pushing down on the tail to perform an ollie, requiring less effort to get a higher ollie. But desipte all of this, risers are not a necessary component on the skateboard.

"Obsolete" components

Rails: Narrow plastic strips that were fastened under the deck along the edges. They used to be popular among vert skaters to whom they provided additional grip during aerial tricks. They also provide a more slippery surface and protect the deck from scratches during board slides. Most skateboarders no longer use rails, since the boards have become lighter and thus holding a grab during aerial tricks has become easier.

Copers: Plastic covers fastened under the truck's hanger which provide a more slippery surface when grinding. They were invented during a time when street skating was in it's infancy but were not very popular since they wore out very quickly and had to be replaced often.

Lappers: Plastic covers fastened on the inside of the truck that covered the kingpin and the baseplate. Their purpose is to prevent the skateboard from being stopped when the truck hits an obstacle (for example when rolling up a curb). It's also called a "Bird" since it's shape resembles the shape your hand makes when giving someone the bird.

Nose guard: Plastic "bumpers" fastened to the nose of a skateboard. It's purpose is to protect the nose of the deck from being damaged when the skateboard hits an obstacle.

Tail bone, aka tail guard: A piece of plastic fastened under the tail of a skateboard. It's purpose is to protect the tail of the deck from wear. Because a tail bone makes the execution of an ollie more difficult and because the skateboard decks today don't last as long as in the 1980's a tail bone is today a very rare accessory.

Because a tail bone makes the execution of an ollie more difficult and because the skateboard decks today don't last as long as in the 1980's a tail bone is today a very rare accessory. Barcodes are frequently used on many products as a convenient way of identification. It's purpose is to protect the tail of the deck from wear. Identification of vehicle registration and last service details are two examples of stickers on the inside of most car windscreens. Tail bone, aka tail guard: A piece of plastic fastened under the tail of a skateboard.
Stickers placed on automobiles, called bumper stickers, are often used by individuals as a way of demonstrating support for political or ideological causes. It's purpose is to protect the nose of the deck from being damaged when the skateboard hits an obstacle. Other methods of underground forms of voting for your favorite graffiti artists' current productions are by an open form of appreciation such as clapping while passing such a sticker (a smile and a kind reminder to a fellow appreciater throughout the day is common place as well).

Nose guard: Plastic "bumpers" fastened to the nose of a skateboard. They are frequently distributed as part of promotional, advertising, and political campaigns; for example, in many voting districts in the US, stickers indicating an individual has voted are given to each voter as they leave the polling place, largely as a reminder to others to vote. It's also called a "Bird" since it's shape resembles the shape your hand makes when giving someone the bird. They may also be used to describe characteristics of the products that would not be obvious from simple examination. Their purpose is to prevent the skateboard from being stopped when the truck hits an obstacle (for example when rolling up a curb). Brand stickers may be attached to products to identify those products as coming from a certain company. Lappers: Plastic covers fastened on the inside of the truck that covered the kingpin and the baseplate. "Stickers" are very widely used when an object requires identification with a word or idea.

They were invented during a time when street skating was in it's infancy but were not very popular since they wore out very quickly and had to be replaced often. Special labels:. Copers: Plastic covers fastened under the truck's hanger which provide a more slippery surface when grinding. [1]. Most skateboarders no longer use rails, since the boards have become lighter and thus holding a grab during aerial tricks has become easier. It has been known for certain companies to patent "their own" color. They also provide a more slippery surface and protect the deck from scratches during board slides. Ink is usually transparent however it can be made opaque.

They used to be popular among vert skaters to whom they provided additional grip during aerial tricks. Additionally specialty inks such as metallic, UV ink, magnetic ink, and more are available. Rails: Narrow plastic strips that were fastened under the deck along the edges. The Pantone system is very dominant in the label printing industry. But desipte all of this, risers are not a necessary component on the skateboard. Ink and base stock color choices commonly conform to the Pantone Matching System (PMS) colors. More risers will equal a higher board which also increases the "pop" a rider gets when pushing down on the tail to perform an ollie, requiring less effort to get a higher ollie. Corona treating or "zapping" makes a substrate more receptive to inks.

Another reason riders install risers is that they evenly distribute impact force from the trucks to the deck, meaning less chance of the deck cracking under pressure. The stock type will affect the types of ink that will print well on them. This rises the deck from the ground slightly, helping to avoid "wheel-bite",. . Risers are placed in between the underside of the deck and the truck. Labels have many uses, from product identification to name tags. Risers - There are special products available to help raise the board away from the trucks and the ground. The most common type is made with a paper stock and a colloquial term for it is a sticker.

It allows less friction and top speeds. Labels come in many forms and can be differentiated by the type of base material, called stock, that they are printed on, and by the adhesive type that they use. The Best Bearings are Super Swiss Six, the balls inside the case of the bearing are made of ceramic clay instead of the traditional metal. A label is any kind of tag attached with adhesive to something so as to identify the object or its contents. Higher numbers indicate that the bearing comforms to a higher degree of precision. Radioactive labels The use of radioactive isotopes of chemical elements, such as carbon-14, to allow the in vivo tracking of chemical compounds. Bearings are graded according to the ABEC scale, which goes from 1-9, in odd numbers. They can be used on ID cards, credit cards, products such as CD/DVD's, etc.

Bearings - Inside each wheel are seven precision ball bearings, secured by a plastic "crown". Holographic stickers are used for authentication and protection against counterfeit. For general cruising most users prefer larger, softer wheels. Blockout labels are not see-through at all, concealing what lies underneath with a strong adhesive. Smaller sizes like 52-55mm keep the board closer to the ground and are lighter which makes tricks easier to perform. Often used on Express mail envelopes. Larger sizes like 65-80mm roll faster which makes riding vert ramps easier. The label can be applied to any object as normal, the top layer can be a removable label that can be applied elsewhere, which may change the message or marking on the remaining label underneath.

The wheels, usually made of polyurethane and come in nine different sizes and suit different types of skating. The bottom layer forms the backing for the top. Wheels - The wheels attach to each hanger. Piggyback labels are made from combining two layers of adhesive substrate. A bolt called a kingpin holds these parts together. This is useful for labeling objects that are to be stored in a freezer for any length of time. The softer the bushings, the easier it is to turn. Freezer permanent- special type of removable adhesive that remains fully permanent under certain temperatures.

The stiffer the bushings, the more stable the skateboard. Semi-permanent - aka repositionable - Adhesion strenghtens fully after application (approx 48-72 hours), allowing the label to be removed easily if placed incorrectly and still be a permanent label. The bushings cushion the truck when it turns. The adhesive is usually strong enough to be applied again elsewhere. Between the baseplate and the hanger are bushings, also rubbers or grommets, that provide the spring mechanism for turning the skateboard. Removable - Adhesion is fairly strong and will not fall off in normal circumstances, but the label can be removed relatively easily without tearing the base stock or leaving adhesive behind on the old surface. The top part of the truck is screwed to the deck and is called the baseplate, and beneath it is the hanger. This is considered the most popular and cheapest option by many self adhesive paper manufacturers.

The trucks are further composed of two parts. For example, full adhesion can be nearly instant, or the label can be almost removable for a short period with full adhesion developing in minutes or hours. Trucks - Attached to the deck are two metal (usually aluminum) trucks, which connect to the wheels. The adhesion strength and speed can also be varied. The longboard, a common variant of the skateboard, has a longer deck. Permanent - Typically not designed to be removed without tearing the stock or using solvents. Skateboard decks are usually between 28 and 32.5 inches long. A disadvantage is durability, because another heat source can ruin or obscure the image, or it may fade completely over time.

Narrower decks are suited to street skaters who like to perform more technical tricks; a wide board often makes it awkward to pull off such maneuvers. Custom labels can be easily be made on location in this way. Wider decks are better suited to vert skaters who need more control and stability while riding down the steep slopes and riding the transitions and walls of a halfpipe. A heating element in the shape of letters or images can be used to create an image on the label. The deck is normally 7 1/2 to 8 inches wide. Thermal - direct thermal label stock will change color (usually black) when heated. An average, all wood deck costs about $50 (US) while a deck including a material such as fiberglass in it can cost up to $70 or so (US). Foil - has the shiny properties of a metal foil.

Sometimes other composite materials, such as fiberglass and Kevlar, are incorporated into deck construction, usually to lighten the board or increase its strength or rigidity. A bumper sticker is usually a vinyl label with a very strong, durable adhesive and Lightfast Inks. This is what gives the deck its strength. They typically require special equipment and printing methods (ultra-violet curing is common) as they do not normally print well with conventional ink. The plies of maple are cross-laminated, meaning the direction of the wood grain alternates between plies. Various plastics such as acetate, vinyl, and mylar allow a variety of features, such as greater strength, flexibility, transparency, resistance to tearing, etc. Decks were originally a single piece of wood but are now usually made from seven plies of Canadian Hard Rock Maple glued together. Latex - a litho stock with some added latex allows the label to be much more flexible and form around certain curved objects more easily than standard litho.

It is covered with grip tape, which adds friction to its surface. Litho - one of the most common base stocks. The deck forms the body of the skateboard and provides a place to stand. Deck - Skateboards are composed of several parts. .
