Bibcycle wheel repair that you can do it yourself at home. Wobbly bicycle wheels can be corrected with a piece of chalk and a spoke wrench.
As you ride your bicycle, you may hear one or both of your tires rub against the brakes. This is a common occurrence, and it simply means that you have either wobbly wheels or your brakes need adjusting. When you have determined that the problem is not in the brakes, then by process of elimination, you can conclude that the wheel or wheels have buckled. This often occurs after hitting a curb or riding into pot holes causing a jarring of the wheels. What you need to do is to balance them or it, through a process called wheel truing. Now don't let the name scare you, wheel truing is very simple and all that is required is a piece of chalk and a spoke wrench. A spoke wrench can be obtained for a few dollars at any store that sells bicycles.
Turn your bicycle upside down. Take a piece of chalk and hold it as close as possible to the rim of the tire without having the chalk touch the tire itself. Now with the other hand, spin the wheel. When the wheel has spun around a few times, slowly move the chalk closer to the rim until it just touches the rim. Now stop the tire and take a look at the tire. There will now be chalk marks indicating where you will need to adjust the spokes on the wheel. Repeat this step using your left hand to mark the other side of the wheel.
In the middle of the bicycle wheel is a network of spokes. The section of the spoke that is to be adjusted is the part that is closest to the wheel; it looks a little like a nut. There are spokes on the left and right of the wheel rim. In order to tighten the spoke, you need to use the spoke wrench and turn it anti-clock wise. To loosen the spoke, turn the wrench clock wise.
The spokes closest to the chalk mark need to be loosened and the spokes on the opposite side of the chalk mark need to be tightened. Using the spoke wrench, turn the spokes in the center of the chalk mark one full turn, and the other spokes a 1/2 turn.
Continue adjusting the spokes until the wheel no longer rubs against any part of your bicycle. You can erase all chalk marks and spin the wheel again while holding the chalk close to the wheel. When no marks appear, your wheel should now be running true.
What is acupuncture? What does it do for pain? Is it for you?
Do you enjoy having injections? Not, likely, you say. Well, how about voluntarily subjecting yourself to, not one, but multiple needle pricks, all in an attempt to relieve pain. If you think that only a masochist would allow such torture to his body, then you need to get up to scratch on acupuncture.
Acupuncture originated in China some 250 years before the birth of Christ. The Chinese found that the insertion of fine needles stimulated or calmed certain parts of the body. Specifically, acupuncture was discovered to have the following effects: (1) Sedation: Prior to a tooth extraction, childbirth by Caesarean section or any number of medical procedures, acupuncture can sedate the patient without causing the none too pleasant side effects of vomiting and dizziness. (2) Relaxation: After treatment the patient feels as if a weight has been taken off his shoulders. His muscles feel loose and relaxed, as if he has just had a fantastic deep tissue massage. (3) Functional Modification: Muscular pain can be eased, if not eliminated, and functionally unhealthy conditions can be corrected.
Sound pretty good, so far? Want to give it a try? Or, are you still not able to get over the needle thing? Well, calm down ? it's not that bad. Really. The acupuncture needles are, in fact, pleasantly unobtrusive. Although they vary in length from 5 to 7 centimetres, they are very fine. Made of silver or stainless steel, they have a thickness of just 0.1 millimetres. With a set of these tools and a metal guide tube the acupuncturist sets to work. Here's the routine he'll usually follow: (a) As an aid to diagnosis he will take the patient's pulse. He will also feel to determine the hardness of the muscles. He will then ascertain where the origin of a patient's pain is. (b) A needle will be inserted about an inch from the pain center. This will cause the nerves in that area to vibrate. Several smaller needles will be inserted around the same area. (c) The acupuncturist will now use reflexology techniques to insert a needle in the foot such that the area affecting the pained muscle is affected. (d) After treatment, the patient should rest for about 30 minutes before resuming with his day.
The actual insertion of the needles is a matter of precision. The needle is placed in a guide tube held in the acupuncturist's left hand. The guide tube is slightly shorter than the needle itself. The acupuncturist will now give a light tap with his right index finger and the needle is painlessly inserted into the skin at exactly the right spot. So, just how does acupuncture work? Well, that is a secret that its Oriental practitioners are not ready to divulge. The closest to an explanation came from a life-long acupuncturist who said, "Acupuncture is simply our way of treating illness. The patient likes the personal touch that is sometimes regrettably missing in Western medical treatment. Through acupuncture we can ease pain and correct an unhealthy condition ? in other words, help one who is sick to regain reasonable health." If you want to do just that, perhaps it's time you went under the needle.
