What is the Difference Between a Band Saw and a Scroll Saw?

!±8± What is the Difference Between a Band Saw and a Scroll Saw?

The structural differences between a scroll saw and a band saw are not so difficult to detect as the differences between their uses. Most of us know that both saws are used for detailed curved cutting, but what their real differences are, to many of us, is more mystery than fact. Beginning on the surface of each saw, we can zero in on the features that make each saw unique and a champion of its own niche.

The band saw is bigger than its scroll sawing counterpart, and although we know they both specialize in curved cuts, their blade designs are much different. A band saw blade, as the name implies, is a large band or continuous loop, a thin oblong blade that fits and rotates around two wheels that spin in the same direction. Similar to a pulley system or the belt systems that exist in your other power tools, the blade rotates or spins in that continuous loop. This design results in superior cutting uniformity which renders the band saw equally effective when cutting both wood, metal, and a variety of other industrial materials as well. On another hand, the scroll saw works more similarly to a seriously juiced up jigsaw; its blade is short and straight (like a jig saw or coping saw blade) and cuts with an accelerated up and down reciprocating action. The scroll saw is effective in the same variety of materials as the band saw, only it cuts with less intensity.

The band saw is perhaps most commonly used for cutting curves and shapes into workpieces. This fine detail work, though, because of the band saw's blade design, can only be performed on the outside edges of a workpiece. This minor limitation, however, does not dissuade many woodworkers as the band saw is a quite universal cutting tool. A band saw can produce surprisingly straight cuts and is used in many woodshops as a resawing machine. Resawing is a technique used to create smaller sections of timber from larger sections of timber by entirely cutting or sectioning a piece of wood or log along its grain. This technique is universally useful, allows you to create new pieces of workable material, and is perhaps where the band saw performs most brilliantly.

Although detailed cuts are among the band saw's strong suits, the scroll makes these detailed curved cuts with surpassing precision. Unlike the band saw, though, a scroll saw has the ability to cut intricate shapes on the inside of a workpiece. In other words, a band saw can cut shapes and a scroll can cut shapes and then cut more shapes inside those shapes. The band saw is strictly a perimeter cutter whereas, by pre-drilling a small hole into a workpiece and fitting the scroll saw blade into said pre-drilled hole, the scroll saw can perform detailed interior cuts as well. This is especially helpful to our most crafty and creative woodworkers.

For all intensive purposes, and with every respect to the band saw, the scroll saw is vastly more effective at detailed craft work. The machine is acutely accurate and allows for huge amounts of creativity in a relatively small package. Not only is the scroll saw's agility during intricate curves and patterns virtually unparalleled, but the tool can also create smooth dovetail joints rendering this machine a true paradise for small scale, intricate craft projects. Similarly, the band saw most certainly takes the cake in universal effectiveness and can cut a straight line with greater ease and accuracy than a scroll saw any day of the week.

In the end, although the scroll saw and the band saw can be used to perform many of the same applications, their subtle differences may make all the difference. A band saw is a champion of curved cutting, but its truest calling comes in the form of resawing and stacked cutting. The scroll saw, on another hand, is, although less universally useful than the band saw, an ethereally good detail worker and can perform detailed cuts inside the perimeter of a workpiece. Each have their own specialized actions and each is an equally valid, equally awesome cutting machine.

Electric Chainsaws - Reliable, Affordable and More Powerful Than You Think

!±8± Electric Chainsaws - Reliable, Affordable and More Powerful Than You Think

When it comes time to clean up your garden or yard, especially after a storm or some nasty weather few tools come in more handy than the standby time tested indispensable tool - the chainsaw. When it comes time to choose a saw you are faced with two choices, gas powered or electric. Now before start thinking "an electric chainsaw come on now! I need something with some guts!" You might think again, unlike in the past when electric chainsaws were a bit underpowered those days are gone now days electric saws have more than enough power to handle the bulk of everyday pruning and cutting.

There are a lot of advantages to owning an electric saw. Some of them are lightness. Electric saws are considerably lighter than gas powered saws. And if you have a lot of cutting to do, especially over head cutting you'll really come to appreciated the difference in weight.

Maintenance is another issue. electric saws have much lower levels of maintenance required to keep them running. Just plug them in and you're good to go. With gas saws they're just more complex and so there is more parts on them. The more parts you have the more parts there are to break. Not to mention the problems with adjusting the choke on them.

Convenience is another major advantage. No mixing and storing gasoline. No gasoline means no spilling of gasoline. Not to mention the hassles of storing gasoline and going out to buy it. And then there is the problems associated with mistakes mixing the gas and oil mixture. If you don't get the gas oil ratio right, the saw might not start.

Remington makes good little saws ideal for pruning and cleaning up the yard. Remington electric chainsaws aren't terribly powerful but if all you need to do is some light cutting then they work pretty well and they're quite affordable. (Some are as cheap as .)

But if you need more power than I recommend stepping up to a Makita electric chainsaw. You'll pay more for this saw - easily twice but they last much longer have more power and are more reliable. There is a pretty good reason why you see them on so many work trucks. the name Makita is practically synonymous with quality and stone reliability.

The one issue that most people have is the problems of being limited to the length of the cord. Those who have large lots might be better served with a gas powered saw but for the bulk of those who have smaller lots, an electric saw with a hundred foot cord s more than enough

When you add up all the advantages that electric saws give, not to mention that they are cheaper than gas powered saws, investing in an electric chainsaw is a pretty good choice.

Makita 5012B - A Good Electric Chainsaw

!±8± Makita 5012B - A Good Electric Chainsaw

Gas powered chainsaws are good. They are powerful enough to make sawing a lot easier for many of us. However, like many other things out there, gas powered chainsaws are also things that could use a little improvement in every aspect. Each one of them also has its own disadvantages. The following are just the most common.

Gas powered chainsaws are very hard to maintain. They still need priming and gas before every usage. And this could be a real hassle especially if you are just going to deal with a handful of branches on your lawn. This is so because usually, the amount of time spent on priming it is five times that of the actual time spent sawing. Now this is just not good.

In addition to this, the cost of this priming and gas fouling is just enough for you to acquire an electric chainsaw which is much more efficient. In other words, the maintenance cost for gas powered chainsaws is quite high. So, if this is to be the case, why stop yourself from buying electric chainsaws. As said they are more efficient and more easy to use.

An example of a good electric chainsaw is the Makita 5012B Electric Chainsaw. A lot of reviews about this product say that this is just really easy to start and really easy to use because it is just very light and really very easy to control or maneuver. Also, its speed is twice more than that of the second fastest in the market! Meaning, we do twice as much work. Now that is just a time saver! In addition to this, this also has fair safety features such as more immediate stopping of chains when the trigger is hit.

Even with this, when you have your first electric chainsaw, it is still best to also ensure your safety. Be sure to buy ear and eye protector. This is really necessary because first, no matter how really careful we are when we're working with these chainsaws, there will always be that noise that could really damage our ears. Also, we can't avoid those flying wood chips and other debris. If our eyes are hit by those, they may cause damage to it or worse, distract us with our work and life threatening accidents may occur. In order to avoid this, we must be wise and purchase the best safety gears available.
