Hand-held chain sharpening tool for chainsaws. pros and cons

The chain saw chain sharpening tool has advantages and disadvantages. Its advantages include:

  • ease of use. it takes more than one day to acquire the skills to work with an automatic machine, while the operation of a manual tool can begin immediately after its purchase;
  • The manual attachment does not need to be repaired. to restore the chain sharpener for chainsaw chain will only need an angle grinder and a diamond nozzle;
  • low price for a manual sharpening set. on average, a manual tool for sharpening will cost 3-4 times cheaper than a machine.

The manual sharpening kit has a few disadvantages as well. The first of these is the low speed of operation. The second disadvantage is the need to secure the chain and file. The third disadvantage of hand tools is the frequent loss of chain saw owners of templates and other small accessories from the kit.

Manual sharpening machine

This method is not suitable for every chain, if the cutting edge has lost its shape, it is very difficult to sharpen and it takes a huge amount of effort and energy. Then it is easier to use a chain sharpening machine. There are two main types of machines, manual and powered, equipped with a sharpening stone or wheel. This is a clearer and truer method that is suitable for everyone in any situation.

Start by loosening the clamp in the chain. After that, let’s correctly install the chainsaw chain, so that the links are directed toward the sharpening stone. Then, most importantly, in order not to spoil the whole work, select the correct angle at which to sharpen.

  • Alternating. each tooth is machined separately and one by one, one by one (with reversed polarity)
  • Sharpening of every second cutter. from the right and later from the left side, you can choose the sequence by yourself. Polarity does not change with this technique

When choosing the method of sharpening with a manual sharpening machine, you should know some aspects that must necessarily be respected:

  • Finding the rational chain sharpening level, depending on the blunt tooth, as a head guide
  • It is forbidden to cut the chain too deep, it reduces strength and power, as well as the chainsaw operating time
  • It’s better to use compressed air after sharpening to blow out all unnecessary shavings. After that, leave the device to rest for a couple of hours.
  • You could not find a more exact method, but it is unfortunately a time-consuming and labor-intensive task.

Makeshift chain sharpening machine for chainsaws

Chainsaw chain teeth dull rather quickly. At continuous operation, you have to grind them with your own hands several times a day. If soil or small stones get on them, the problem is exacerbated by deformation. Fine sawdust falls from under the chain teeth instead of chips and efficiency is noticeably reduced. Timely sharpening removes a minimum layer of metal, increasing the life of the saw.

Often the user doesn’t notice the chainsaw’s blunt teeth and keeps on working. Lowers productivity, increases fuel consumption and machinery loads, the bar and drive sprocket deteriorate sooner. To avoid these troubles, it’s important to look at the condition of the sawdust while working. The following signs are indicative of the need for chain sharpening:

The malfunction is also indicated by a change in the force of the feed. Sharp chain teeth start to cut at the lowest feeds. When a chainsaw has to be “forced” to work. the teeth are blunt. It cuts slower, requires more effort from the user. The attentive owner notices the problem at a glance.

How to sharpen a chainsaw chain

Chainsaw chain sharpening is a procedure regularly encountered by gardeners and professional woodcutters. In this article, the master plumber will tell you how to restore the damaged teeth of the saw headset, and quickly return it to its previous working condition.

To understand how to properly sharpen the chain, it is necessary to understand the basic principles of its construction and operation. You cannot just sharpen the chain by eye. you need to know the basic characteristics of the chain and its parts.

The chainsaw chain consists of three types of links made of high-alloyed steel:

  • Cutters are the main elements of the chain. A distinction is made between right- and left-hand drive shanks, which are arranged alternately; their cutting edges are located above the plane of the bar. Tooth design incorporates depth of cut limiters.
  • Driven (shanks). serve to transmit torque from the gasoline motor to the chain through the drive sprocket. This feature extends sprocket life and gives the chain a more stable hold on the bar.
  • Coupling. connects the chain shanks and cutting teeth.

One of the main elements of the chain is the cutting tooth, which plunges into the wood and removes shavings. The tooth depth limiter determines the thickness of the wood chip and limits the depth of penetration into the wood.

Depending on the type of chain the recommended settings in relation to the limiter are 0.025″ (0.65 mm) or 0.030″ (0.75 mm).

Long service life of any chainsaw depends on proper care and use, including the chainsaw. Good performance of the latter affects the performance of the device and the productivity parameters. Failure to sharpen in a timely manner can cause some problems with the saw itself. The most common ones are:

  • Crooked Sawdust;
  • High loads on the saw, resulting in increased wear of the parts of the device, and therefore a reduction in the service life of the entire device;
  • Increased fuel consumption.

If the saw produces fine, dusty chips, and the saw itself sinks into the cut with great force, it is a blunted target.

There are other signs of a dull chain:

  • The speed of the tool has decreased;
  • Uneven and sharp sawdust is formed;
  • You have to put a lot of effort into cutting wood;
  • The chain is loose or slack.

The chainsaw chain can quickly become blunt for the following reasons:

  • If you work with the saw too often;
  • When the operator puts a lot of pressure on the saw while sawing;
  • If the chain is made of poor quality metal or if the steel has not been properly heat-treated;
  • When frequently sawing raw or resinous wood;
  • When sawing hardwood trees such as: oak, birch, cherry, acacia, elm, ash and others;
  • When the chain encounters obstacles like sand or stones;
  • When the chain is not properly sharpened or has insufficient tension while working.

The design of all chain saws is similar, so the algorithm for removing the chain will be the same:

  • You should first wear cotton gloves to protect the chain from being cut by the saw’s cutting edges.
  • Remove the protective cover from the working part of the chain saw and lay it on a flat surface on its side.
  • Use a socket wrench of needed diameter to unscrew the fixation nuts that hold the body and the guide bar, remove the top cover of the body.
  • Now slide the bar all the way down to the sprocket, thus loosening the chain, and remove the operating elements from the mounting bolts.
  • Disconnect the chain from the bar.

The Dremel 1453 is an inexpensive tool for sharpening chain saws

It only takes a few minutes to sharpen the chain using an angle gauge and a set of sharpening stones. Included in this set are three sharpening stones of different sizes to fit most chainsaws. Kit is for your Dremel.

Very easy to use. Select the right size stone and insert it into the chuck. Then visually check the sharpening angle.

Chain set-up

A sharpened chain is essential for safe, productive and high-quality chainsaw use. It is almost impossible to work with a dull cutting element because the saw will “walk”, vibrate and slip. You need to work hard to cut through the wood and that reduces productivity.chainsaw chain is quite simple. Its main elements are the teeth that make the cut. They have to be as sharp as possible to cut any type of wood of different density. They are located on both sides of the chain and alternate during rotation.

So, it is not difficult to imagine that all the teeth need to be sharpened to make the tool work properly. cutting elements are made of special hardened steel that is easy to sharpen, durable and reliable. In addition to the teeth, it is impossible not to mention the links, faces and stops, which are also part of the chain.

Tooth sharpness depends on chainsaw performance and frequency of use.

It is very easy to spot the need for sharpening6

The more often a tool is used, the sooner it becomes blunt and needs sharpening. If it is not carried out in a timely manner can be injured, as blunted links can slip off the wood, and if there is no automatic brake, the operator can hurt himself. Check the sharpness of the chain before every use, especially if the tool has been sitting idle for a long time. It is important to remember that with each sharpening, the metal is worn away and becomes smaller, so do not do this indefinitely.

It is recommended to change a chain every 15-20 sharpening intervals to keep a tool in good working order.

Correct chain tensioning

A special tensioning device located on the bottom of the body of the electric saw helps to tension the chain correctly on the electric saw. To do this correctly, you must first get the bar on the chain saw correctly. There is a simple technique for attaching the chain correctly.

  • Loosen the nuts securing the bar to the body.
  • Use one hand to lift the bar with the far end up, without removing it from the saw.
  • with the second hand place the cutting element on the guide sprocket of the guide bar and insert the shanks of the guide tines into the grooves (“grooves”) of the guide bar.
  • The lower part of the cutter bar is put on the drive sprocket and the bar is lowered to the horizontal position.
  • With the guide bar pressed lightly against the body with the fastening nuts, start tensioning the cutting element by turning the tensioner adjusting screw with a screwdriver.
  • As soon as the cutting element is sufficiently tensioned, the fastening nuts are tightened.

Checking the tension: the operator takes hold of the upper bowstring by hand and lifts it to the top. Tension is the amount of tension required when the chain is lifted to such an extent that the shanks of the three hooks are visible, i.e. 0.5 to 0.6 cm above all of the lifted guide bar. If the chain meets this requirement, the operation is complete. If the tension is incorrect, the attachment nuts are loosened and either further tensioned or loosened. After adjusting, retighten the nuts and check the tension again. It is often considered normal tension if the bowstring makes a resounding click when released, banging against the bar.

Sharpening of the cutting parts is not a complicated job, but it also requires some knowledge and experience. The technique described above is the same for chain saws and electric saws, as they differ only in the type of engine. The main requirements when sharpening any chain saw are caution, attentiveness and accuracy.
