What is a chainsaw and how does it work?

The name kind of says it all, a chainsaw is a saw that utilizes a rotating chain with a set of teeth attached to it, that moves along a guide bar. The guide bar is an elongated steel bar with a rounded end that guides the chain through the edge slot and varies in length – between 16 and 36 inches. The bottom edge of the chain runs through the gauge and this keeps the chain lubricated. The chain is driven by a sprocket that is connected by a drive shaft to a motor, which can be either electric or gas powered. We’ll look at the differences, advantages and disadvantages of gas, electric cord and electric battery motors a little later

Traditionally gas powered chainsaws are the most common. A gas powered, two-stroke engine of between 30 and 120 cc is used to drive the chain. The engine works through a centrifugal clutch to control the torque sent to the chain sprocket – when the engine is at idle or the chain becomes jammed, the clutch will disengage and the chain will stop moving. All chainsaws have an oil reservoir to keep the chain lubricated, this is a vitally important factor in keeping the chainsaw working properly.

The chain moves at high speed and cutting teeth that are attached in between the chain links, rip through the wood. It is important to keep the chain at the correct tension to prevent it from snapping off or coming loose from the sprocket and guide bar. To achieve this, chainsaws are fitted with a tensioning mechanism.

History of the Chainsaw

The first cutting tool resembling the modern chainsaw was invented by a German orthopedist Bernhard Heine, in 1830. The device that was designed to cut bone consisted of a chain with cutting teeth that ran along a guide blade. This was a medical instrument and it was never intended for the heavy duty work that we now associate with chainsaws.

The continuous chain driven saw was patented in January of 1905 by Samuel J. Bens and was known as the “endless chainsaw”. This led to the first portable chainsaw being invented in 1918 by James Shand, a Canadian Millwright. However, it took some time before the gas powered chainsaw came onto the market in 1927.

Since these early days, the basic principle behind the chainsaw remains the same. New developments in technology have made it possible to get more power from smaller engines and together with the use of metal alloys, modern chainsaws are a great deal lighter than the early versions. Technological advances have also reduced vibration making them easier to use and there have been several advances in safety.

Why Buy a Chainsaw?

If you’re not a professional that needs to use a chainsaw for everyday work, you may be wondering why you would want to buy a chainsaw. Apart from the boost to your manhood that comes from owning the ultimate power tool, there are some very sound reasons why owning a chainsaw can save you time and money.

As trees in the garden grow taller and wider they can pose a threat to buildings, overhead power lines, fences, gates and garden walls. Many of us need to keep the trees in our gardens under control both for our own safety and that of our neighbors, it is not permitted to have trees along the boundary of your property extending too far into adjoining properties. Calling in a tree felling company once or twice a year can become costly, so doing it yourself is a great alternative. If you’ve ever cut through a large log by hand, you’ll know that it’s tough work and takes up a lot of time, especially if doing it alone. A chainsaw makes quick work of this task.

After a storm one very often finds fallen trees and even poles and parts of wooden structures blocking the driveway or simply littering the garden. In order to remove them, you’ll usually have to cut them into a manageable size. At times like these, you’ll be very happy to have a chainsaw at hand.

As trees grow older, some branches may die and become a risk, as they may break off at any time. It’s important that you cut off the dead branches before they cause major harm.

If you have fruit trees, you’re probably spending a lot of time at the end of every winter pruning them to ensure a good crop in the following summer. I’m sure you’ll agree that a chainsaw will save you a lot of time and effort when keeping a fruit orchid in top condition.

Having a wood burning fireplace or pizza oven is a wonderful thing. However, keeping a good stock of usable firewood is a costly exercise. Cutting down your own trees for firewood will save you a fortune every year and when you snuggle with your wife or significant other beside the crackling flames, there’s a good chance that you’ll get some extra affection when she thinks of how you’ve toiled to provide this warmth.

Actually, there’s some real evidence to suggest that cutting your own wood increases your chance of getting some action. A study into scents that women find attractive has shown that the smell of freshly cut wood on a man is rated very highly. So yes, owning a chainsaw can improve your love-life.

Many carpenters are moving toward crafting furniture from natural whole logs and it’s also popular among sculptors. So there’s also a use for chainsaws among the more creative souls. What to consider before buying a chainsaw.

Before we go into the different types of chainsaws available to you, it’s important to look at safety. Modern chainsaws come with a number of safety features that help to prevent accidental injuries. These include chain break, which allows you to stop the chain instantly in the case of a kickback, a chain catcher which prevents the chain from hitting the operator when it comes off the chain rail and the rear handle guard that also protects the operator from a loose chain.

Despite the many safety features that are incorporated into the design of chainsaws, there are risks that come from handling a tool with that amount of power and cutting ability. If you’ve never used a chainsaw before, be sure to get some good training, so that you are able to operate it safely.

All chainsaws require maintenance, some more than others. So before making your decision, you should know what maintenance will be required. A gas powered chainsaw will require the most maintenance. The engine will require the usual service, typical of any two-stroke engine – changing the spark plug and occasionally cleaning the carburetor. Along with this, the air intake filter is easily clogged by woodchips that fly off whilst the saw is being used, so it needs to be checked and cleaned regularly.

The oil lubricating the chain can also accumulate wood chips and needs to kept under check. With an electric or battery chainsaw, you’ll have less to worry about, as the engine does not require any regular maintenance. You’ll have to ensure that the oil reservoir always has oil to keep the chain lubricated and that the oil does not accumulate dirt. Other than this there is not much to worry about. All chainsaws do, however, require chain sharpening periodically and this will depend very much on the amount and type of usage.

Deciding on the right chainsaw for you

The first thing you should decide on is the length of saw you require. There’s no point in getting a chainsaw with a 16″ guide bar when you’re going to be cutting large logs or trees. Likewise, a 36″ guide bar could be serious overkill for some people. Look at the size of the trees that you’ll be cutting and choose a guide bar length to suit your needs.

The overall size and weight of the chainsaw should also be considered. You want something that you can handle comfortably and safely. You should also take into account the working height. If you’re going to be working on a ladder cutting high branches, remember that a heavy chainsaw can be hazardous.

Once you’ve established these basics, you should decide on the type of motor you want. Let’s take a look at the three options – gas, electric or battery powered chainsaws. Each has their own set of pro’s and cons and the one that is best suited to you will depend very much on what you intend to use it for.

Gas Chainsaws

These are the first choice for professionals because they offer a lot more power and can be used anywhere, even far from the nearest electrical power outlet. One of the disadvantages of gas chainsaws is the amount of maintenance that they require, as discussed earlier. For many people living in the city and suburbs, the noise may be a problem. The gas engine on a chainsaw is usually around 100dB and upwards. This is extremely loud and could be a problem in built up areas. In some areas, noise level restrictions prevent the use of gas chainsaws.

Electric Cord Chainsaws

An electric chainsaw has a lower power to mass ratio than a gas-powered equivalent, so you won’t get the same power from an electric chainsaw. That being said, if you only need to cut smaller branches and trim hedges, an electric chainsaw is an easy and economical option, with very little maintenance required. You are, obviously restricted by the distance from the closest power outlet – there’s only so far that you can run a power cable. An electric cord can also be a nuisance when cutting higher branches as it can become entangled in the branches below. Above all, an electric chainsaw is much quieter than a gas chainsaw

Battery chainsaws

Advancements in battery technology have made power tools much more versatile. So if you want the convenience and quiet running capabilities of an electric chainsaw without the hassle of a power cord, a battery chainsaw could be just what you’re looking for. They are, however, more expensive and you have the extra weight of the battery to contend with. Another drawback of a battery chainsaw is that you are limited to the battery’s charge cycle, typically you’ll get around 30 minutes cutting from a battery before it needs recharging.

While electric chainsaws have their place, gas chainsaws remain the most common and for that reason, we’re going to look at two of the best value gas chainsaws on the market.
