Cutting Through (ipod video) the Truth About Chainsaws.
No commentsBy vivek1
There is no mistaking the distinctive sound of a chainsaw, screaming as it bites through a hunk of wood or the bark of a tree. There are even chainsaws which are used to cut through concrete, brick and natural stone. Chainsaws are perhaps one of the most convenient power tools available, and can save a lot of time and effort in construction and felling.
Although the origin of the chainsaw is debatable, it is determined that the first chainsaw was made around 1830 by Bernard Heine, a German orthopedist. This chainsaw was used for cutting through bone. Although this may have been for a more gruesome purpose, the idea was born! Nowadays, chainsaws have almost completely eradicated the use of simple hand-held saws in the forestry sector.
A chainsaw is basically a mechanized saw that is normally portable and handheld. It is widely used for felling trees, cutting branches, harvesting firewood and cutting through wood for various other reasons. It normally has an engine that runs on petrol, electricity or even a more advanced internal combustion motor.
As mentioned previously, there are chainsaws which can be used to cut through stone. Chainsaws that are used to cut through stone or concrete are almost identical to a regular chainsaw. The only difference is that the cutting edge will be made with diamond, and the chain can only be lubricated with water to avoid friction. A normal chainsaw for felling wood will be lubricated with oil or the fuel that runs the motor. Chainsaws that cut through stone or concrete are normally used in construction, and are very precise in helping to avoid damage to the surrounding structure.
There are stringent safety measures to adhere to when operating a chainsaw. The most dangerous thing about a chainsaw is the “kickback” or “push-back.” This is when the tooth at the tip of the guide bar catches on the wood instead of cutting through it. This can throw the bar with its moving chain straight up towards the operator or anyone standing nearby. Push-back frequently occurs when the top of the bar is used for cutting. To avoid push-back you should always be alert to forces or situation that may cause the material to pinch the top of the chain. No more than one log must be sawed at a time, and the saw must never be twisted when you are withdrawing the bar from a plunge cut.
Another chainsaw danger is pull-in. This is when the chain on the bottom of the bar is suddenly stopped. The chain on the bottom of the bar stops when it is pinched, caught or encounters a foreign object in the wood. The reaction of the chain pulls the saw forward and may cause the operator to lose control. Pull-in frequently occurs when the bumper spike of the saw is not held securely against the tree or limb and when the chain is not rotating at full speed before it contacts the wood. The trick to avoiding pull-in is to always start a cut with the chain rotating at full speed and the bumper spike in contact with the wood.
There are many more risks associated with chainsaw operation. The danger of timber falling and trapping the operator is something to take into consideration. The chain must be maintained properly, and you should never use your chainsaw to cut into inappropriate materials. Even just the vibrations of the chainsaw can cause White Finger Disease. Protective clothing should be worn at all times. Some recommended protective gear is a hard hat, safety glasses, thick gloves and ear muffs. In most countries, you will be required to undergo training in maintenance and operation before you will be allowed to use a chainsaw.

Craigslist 101
By Rocky Mcmahon
Although Craigslist has been around in one form or another since 1995, there are still some who have no idea how to use Craigslist. These individuals are missing out on a wonderful opportunity to be a part of a growing and continually evolving online community. This community is an excellent resource for finding information, finding jobs, finding friends or dates, making purchases, selling items or discussing important issues. This article will provide a brief introduction to each of the major sections on Craigslist.
Community Section
The community section of Craigslist is very useful for finding a great deal of local information. This may include activities, events, activities and lost and found just to name a few. This is definitely the section to check out if you are looking for things to do or see in a particular area.
Personals Section
The Personals section is where individuals can meet platonic friends or romantic partners. This section is set up with a number of different categories making it possible for both heterosexuals and homosexuals to find potential dates. The personals section is restricted to users over 18 years of age.
Discussion Forums
The discussion forums provide a location for individuals to voice their opinions, answer questions or otherwise exchange information. This section is divided into a number of different categories to make it easier for users to find others who share their interests. Certain categories allow users to post without logging in while other sections require users to log in before posting.
Housing Section
Craigslist’s housing section offers a variety of options related to lodging. Users of this section can find apartments or homes available for rent, sublet opportunities, potential roommate situations, house or apartment swaps, real estate sales, vacation rentals and even storage, parking and office space for rent or sale.
For Sale Section
The for sale section of Craigslist is largely self explanatory. Like most sections, it is divided into a number of different categories. Each of these categories describes the types of items which are offered for sale within the category. Additionally, there is a wanted section where users may post advertisements seeking to purchase particular items. Not all of the items listed in the for sale section require a fee to be paid to receive the item. Some of these items are available for free or in barter situation.
Services Sections
In the services section, service providers may place advertisements for the types of services they offer. Advertisements should be placed in appropriate categories but if there is no appropriate category the advertisement may be placed in the generic small business section.
Jobs Section
The job section is by far the most extensive section on Craigslist. This section is broken down into a number of different categories to make it easier for users to search for potential career matches. Users may find full time as well as part time opportunities in this section as well as telecommute positions and contract positions.
Gigs Section
The gigs section is similar to the jobs section but advertisements in the gigs section are supposed to refer to one time only opportunities as opposed to ongoing work. For example advertisements for volunteer staff needed for a one day event should be placed in the gigs section while advertisements for full time staff positions should be placed in jobs.
Resumes Section
The resumes section enables job seekers to post their resumes. The key to getting noticed in this section is to use a catchy headline for the resume. The resumes are not divided into different categories making it difficult for users to search through these resumes.
