How to Adjust Your Bike Seat

 If there is anything easier than riding a bicycle, it is probably adjusting the bike seat. You can surely do it, even without your toolbox. Just loosen the bolt holding the seat, adjust its height and position, tighten the bolt and you’re done. However, there are cases when the seat becomes hard to adjust due top the presence of rust. It’s still not much of a problem, though. Ample amounts of lubricating oil should do the trick.

Materials Used:

• allen keys
• lubricating oil (if necessary)

Step 1: Purchase Allen Keys for the Bike Seat

Allen keys are small wrenches that are made to attach and loosen bolts with patterned heads. The wrenches, coming in different sizes, are used mainly to adjust bicycle seat bolts. You can find a set at any hardware store at affordable prices. It’s a a good investment, especially of you own more than one bicycle type.

Step 2: Use an Allen Key to Loosen the Seat Bolt

Try your set of Allen keys on the bolt just below the bike seat and find which key fits the bolt’s pattern. Upon finding the key, use it to loosen the bolt. Apply lubricating oil on the bolt if it won’t budge.

Step 3: Adjust the Seat

Determine the right height for your bike seat. Ideally, your knee should be slightly arched when your foot is on the pedal. Move the seat to your desired height and position. If the seat does not budge, apply lubricating oil.

Step 4: Tighten the Seat Bolt

When the bike seat has been adjusted, return the bolt to its placed. Use an Allen key to tighten the bolt. You can apply lubricating oil on the bolt and the grooves to enforce free flowing movement, in case there is rust. Dont forget to check if the seat is firmly affixed. Loose seats can cause accidents.

Seat Adjustment is a Requirement

Knowing how to adjust a bike seat is a requirement when riding bikes. A well-positioned seat promotes proper riding posture, which eases pressure on your back and legs. It can also increase your speed, since your legs are not hindered or strained by their position. Just refer to this procedure whenever you feel the seat is hindering you from a good riding experience.

How are Paintballs Made

 What is a Paintball?

Paintball is a sport in which the aim of the participants is to eliminate people on the other team by shooting at them paintballs. These so-called paintballs are spherical gelatin capsules primarily containing polyethylene glycol, other non-toxic and water-soluble substances and dye. The paintball can be aimed and shot from a compressed gas powered marker.

Paintball is a sporting game that draws the attention of many people and over 10 million people alone in the United States. In fact, statistics show that paintball is a safe game to play; even safer than tennis.

How to Make a Paintball?

As mentioned above, a paintball is a gelatin capsule, which has a thin skin with colored paint inside. They resemble large capsules and are non-toxic. The paint used in the balls are biodegradable, water soluble and easily rinse out of clothing and can be removed or washed from human skin with plain water. When a paintball hits a player, it leaves behind a brightly colored splat that can easily be removed with water and soap before the next game starts.

Paintballs are referred to as softgels, and can only be made on softgel encapsulating machines. These machines are expensive but are efficient enough to manufacture paintballs at a low rate. The following steps illustrate how a softgel encapsulation machine works and how paintballs are made:

Step One

Gelatin is first melted and then this hot gelatin is molded into two thin gelatin ribbons. Each of the ribbon is made to pass over a rotating die.

Step Two

The dies are designed so that they can form capsules of standard shapes and sizes, which give paintballs their actual look. Softgels can be spherical like balls or even shaped unusually. Each die presses against the other as they are rotated.

Step Three

As the dies are made to meet, both shells are filled with paint, which is injected into the area between the sheets.

Step Four

The die is still rotated with both pressing against one another to form a filled capsule. The seam on the capsule depicts where exactly the two sheets had met.

Step Five

Finally, the sealed gelatin capsule is taken out of the rotating die. The capsule is dropped out of the machine and it becomes a paintball, which is rubbery and large enough to be used to shoot.

Step Six

These bouncy capsules are placed in trays for drying and allowing the gelatin to shrink during the drying process.

Technicians who manufacture paintballs usually check or monitor the encapsulation machines. They randomly check the quality of paintballs to see if they meet the desired specifications and conduct a final check as soon as the balls have dried up. When ready, the paintballs are packed and moved onwards.
