A skateboard deck is made up of curved layers of wood that are combined with glue. Then, the skateboard deck is trimmed down to a board shape that is practical. Trucks are typically made of aluminum or other metal alloys. They are made by melted metal formed by a mold and later drilled into the skateboard deck. The wheels are formed the same way, but with polyurethane. They are attached by ball bearings to complete the product.
Skateboarding, in one form or another, has been around since the late 1950’s when the first brave pioneer first attached roller skate wheels to a piece of wood. As skateboarding progressed to mimic surfing, skateboards evolved with the style of riding. Skateboards grew and changed shapes as riders experimented with everything from plastic to fiberglass to aluminum constructions - all in an effort to push what was possible. Like most sports or art forms, progression is at the heart of skateboard innovation.
The laws for skateboarding helmets vary from state to state. Many states require that skaters wear a helmet under a certain age, and some states like California make all skaters under 18 wear a CPSC Certified helmet at all times. CSPC skateboard helmets usually have an EPS protective liner that meets the safety standards for skateboarding. Make sure you check your state's regulations before ordering.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
