How to change a chain on a saw. How to determine the degree of tension

How to put a chain on a saw correctly

In order for the chainsaw to work properly, you need to monitor the correct operation of all its devices. The caterpillar established according to all the rules will save you from possible injuries. Installation work is carried out using devices:

Particular attention should be paid to the degree of exacerbation of the chain and its tension. The track should be regularly monitored:

  • First you should study the saws that are fixed with the lid on the coupling.
  • If the circuit is required, the nuts are loosened by the wrench. It is forbidden to simultaneously free the voltage of the brake of the quapi.
  • The brake block moves to the side. Grooves that allow you to pull the chain part are especially notable.
  • The saws move on the left, trying to touch the main star. One of the elements of the chain is fixed on the leading part, the shank is fixed in the tire holes.
  • Screw adjustment allows you to correctly pull this part. As the lids are set, they begin to fix the nuts.
  • The guide bar is located upwards, and the nuts are delayed until it stops.
  • The distance of the track on the tire is checked.

It is necessary to set the chain, checking the degree of its tension after each installation or replacement. Insufficient mounting of the part can lead to the fact that it will jump off the base of the tire and injure workers.

The tension value is checked manually, after putting on the gloves on the hands. It is worth considering the fact that in the process of using the tool any chain changes length indicators. For this reason, the verification should be carried out regularly.

The direction of the chain and which side to wear

Chain of the chainsaw, if you carefully examine, has saw teeth directed in one direction. Therefore, the correct direction of saw teeth on the guide tire is very simple to determine: if you place the chainsaw itself in the plane, which it is in the process of operation, then a number of teeth located on top of the guide tire should be directed by sharp edges to the end of the tire. While a number of teeth, which is located below the chainsaw, should look in the opposite direction, towards the leading star.

When you need to shorten or stretch the chain

What to do when the chain requires shortening or stretching, when it is necessary to add or remove links?

First, let’s figure out in which cases you need to shorten the chain, that is, remove the links from it.

The chain is shortened:

Accordingly, you can make a chain longer if:

  • A longer tire will be installed on the saw;
  • Some links are so worn so that they need to be completely removed, which means that the chain will become shorter and it needs to be lengthened to the same size.

As a rule, one or two links are removed. To reduce or increase the size of the chain, you will need the following tools:

  • Riveling machine. A punch (a mechanical device, works on the principle of the press, is equipped with tips for squeezing rivets and interchangeable grooves for a different step of the chain);
  • Rivet and rolling machine (designed for chains with a step from 1/4 ″ to 0.404 ″).

What to do if the chain sags

If the chain sags, there is a risk of injury to the operator. After all, the saw canvas can break or just fly off the guide stars. Of course, modern chainsaws have security systems and emergency stops, but these systems do not always work correctly.

It is important not to install a chain with defective or damaged saw links on a chainsaw, in addition to the danger of tearing to break at any time, such a chain will sharpen the guide grooves of the tire, which will lead to its skew, uneven cut and failure of the guide tire.

Because of which the chain can sag during even short operation?

  • There may be problems with the guide tire. Sometimes, due to the oversight of the operator or due to severe wear of the thread of the fixing bolts at the place of fastening of the guide tire, vibration may occur, which causes weakening the tension of the chain. It is necessary to check the condition of the fixing bolts and, if necessary, replace them with new. When the bolts are tightened enough, there are no such problems.
  • With a fairly neat handling of a chainsaw over time, any chain may be worn out. Try to repair it or collect it from a few one. Useless activity. If the chain headset is stretched due to natural reasons, then it will be best to purchase a new.
  • Asterisk stands with distortion. Due to the displacement of the tooths of the sprocket, sagging may occur. In this case, it will be best to contact the service center for the repair and setup of the position of the leading star. It is quite difficult to fix the leading star in the correct position, because you will have to dismantle a lot of small details, remove the guide tire, and then collect everything in the reverse order.

How to put a chain on a chainsaw: Instructions, recommendations, main methods

Chain. An important element of the chainsaw structure. It is on it that the greatest load is on the time, so high.Quality and systemic care is required. When using any model, it is important to know how to wear a chain correctly, monitor its stretch. If you fix it incorrectly, there is a risk of stretching and leaving the grooves. The productivity of the saw is reduced, and the risk of injuries at high capacities is also increasing.

Why the chain flew?

There are several reasons why the chain can fly during operation. This may be due to the improper operation of the tire or insufficient stretch. The problem sometimes appears with an insufficiently fixed lead and led star. Determining the reason allows you to accurately choose the required repair, tools.

The tire weakened

With a decrease in the tension of the chain, the problem is often accompanied by a weakening of the tire itself. To check its condition, you need to inspect the place between the upper plate on the casing of the headset and the inner surface on the case. When weakening fixing bolts, the tire begins to move, which can be seen by characteristic vibration during sawing. With frequent operation, it is recommended to regularly clamp the bolts.

Figure 1. The tire weakened

If you yourself decide to tighten the tire, then you need to find and lower the chain brake. Turn the tension screw so that the chain is tightly in the grooves. After that, pull the chain in the direction of movement, if it is too tight, loosen the screw.

The chain stretched out

Any functional changes in the chain lead to a decrease in the productivity of the tool, injuries during operation.

It should be regularly ensured that there is no deformation of metal and stretching more than 1 cm.

If such a problem still arose, you need to purchase a new chain or adjust the old.

Disconnect the links of the chain on the machine or fix it in a vice, stack the rivets with a file and knock them out using a beard (it is not recommended to use a grinder).

Delete 1-2 links depending on the degree of stretching of the chain. After that, put all the elements in place, insert a rivet and beat it with a hammer, use a special riveting tool. For reliability, it is recommended to use a welding machine. At the end of the work, to flow excess and burrs with a thin suction.

Problems with the leading star

Sometimes a sagging chain occurs due to problems with the leading star. The most common situation is when it is poorly fixed. A step.By.Step algorithm to twist the asterisk:

  • Remove the protective cover of the engine.
  • Remove the air filter and unscrew the candle, putting in its place a special stopper for fixing the piston in real estate.
  • The key for the grinder scroll the clutch disk clockwise to the maximum upper position. Check the density of fixation of the asterisk, adjust its position. Figure 3. Leading star on a chainsaw

After clamping, collect a chainsaw, be sure to put on a protective casing. When assembling, check that the chain is tightly on the tire.

Checking the level of tension of the saw chain for the chainsaw

After the equipment is assembled, it is advisable to check the correct installation. With a released brake, the spare part should be adjacent to the lower surface of the guide tire without a sag, quite tightly. To achieve the result, delay the installed element in the middle of the tire, then scroll it. Repeat the procedure several times before obtaining the proper effect.

After replacement the best saw chains for chainsaws You should drive the tool at low speeds, first filling the oil into the automatic lubricant system.

As you can see, independent replacement of the spare part is not complicated at all if you adhere to recommendations, instructions and procedures. Get high-quality elements in the Benzosip online store, then their installation will not take much time.

How to sharpen a chain

As the operation is used, the chain is inevitably blurred. This is especially often observed in cases where the tool is used in work on an everyday basis. Therefore, normally, the circuit of the electric saw is regularly sharpened. You can implement it yourself at home. For this you will need the following tools:

  • Flat shape file. It adjusts the deep limiter;
  • Circular file. Must have approximate lines applied to the surface;
  • Calibration device;
  • Mandrel, which is used to correctly determine the angle.

The main way to sharpen the electric stove chain at home is associated using such a simple device as a file. The algorithm of actions is this:

  • First, the chain is pulled onto the saw and fixed with the clamp.
  • Adjust the angle of sharpening. To do this, use slots that are located on the bus.
  • Insert the file into the hole so that it is well pressed.
  • The first tooth, (from it begins to sharpen the process) separately, so that then nothing to confuse.
  • Perform a chain movement towards yourself.
  • Loosen the clamp and move along the tire towards yourself.
  • Insert the file into the hole again and repeat these steps.
  • At the end of the work, it is necessary to make sure that the tint of the circuit on the electric saw is the maximum. Then the tool is ready for work again.

Can be sharpened in a special camp. For this, the cutting element is fixed and the machine is connected to the network. Engines installed in the carriage, rotate. After that, you need to lower the carriage using the handle. The disk is pressed to the cutting edge and the grinding. Then the carriage is raised and the mount is loosened, after which the element is scrolled “through the tooth”.

It is clear how to put a chain on the electric saw. This can be done manually without using special equipment. But if there is nothing at hand, you can even sharpen the teeth. This is done using a drill or ordinary screwdriver. This method allows you to quickly achieve the result, although the quality of work will be low. Therefore, it is better to use files or give for sharpening a master who has a professional machine.

Installation of the circuit on electric saw

Not all modern chainsaws are equipped with a installation wheel, which significantly simplifies the installation procedure of a saw canvas. Systems with a installation wheel among household chainsaws are generally a rarity

Therefore, it is very important to know the technology and sequence of installation of the chain on the chainsaw

The main points should be paid to:

  • Prepare a flat surface on which you will put together a chain and a tire. This will minimize the chance of damage to the chainsaw or loss of small details. A tire is laid out on the prepared surface and a chain parallel to the next parallel.
  • Remove the protection of the sprocket, on modern chainsaws, it is enough to unscrew the lamb nut, on older models, you may need a unit key of the corresponding size.
  • At the base of the guide tire, turn the stretch asterisk to the right to the right. Only in this position is the chain set.
  • Then the chain sequentially the link behind the link is placed on the fixing groove on the guide tire. Install the chain from the top of the guide, gradually turn it so that the tire is always on top, and the chain from below, this will always be in a stretched state and go to the guide groove without problems. When you perform this item, be sure to put on thick protective gloves, because your fingers will touch the cutting edge. If you look from above, then the cutter is always located forward by the end of the guide tire.
  • And put on the tire and chain on the leading star.
  • Fasten the cover of the chain star in your place. Make sure that all mounting pins coincide with holes. Incorrect installation with distortions or not to the end may be the cause of extraneous noise, rattling.
  • Make sure that the guides “go” into a special mounting gutter.
  • After installation, check the fixation of the chain on the chainsaw and on the tire. Everything should be reliably fixed without backlash.

An important point is the degree of tension of the circuit after installing it. Setting the correct tension is very simple and will take no more than three minutes. First you need to loosen the nuts on the protective cover. Using a freely rotating adjusting screw, catch the correct tension so that the chain does not pull from the edge of the guide tire of more than 3-5 mm.

It remains only to tighten the nuts and control the tension. If you need adjustment, to set the tension again.

How to install a tire and a chain on a chainsaw, watch in the next video that presents a clear algorithm of actions:

Ways to check the degree of tension

Checking the degree of tension is an important point, since the consequences of incorrect adjustment can be fatal for the sawmill. The quality adjustment quality of the chain tension can be determined by:

  • When moving the product manually, it should not seize or signs of the severity of its movement occur.
  • The cutting element must be checked for the weakness of the tightening, for which to take up the link and try to pull it up. The normal value of the tension should correspond to the exit of the shanks from the tire (in its middle) no more than 2/3.
  • In the process of moving the device, there should not be creaks and other extraneous noises.

In conclusion, it should be noted that the chain should never be adjusted to the hot, as this will necessarily lead to a number of negative consequences. As a result of such actions, not only the tire and chain, but also the leading star may be replaced.

How to remove the chain drive on a chainsaw

The clutch of the chain saw, which is also a leading star, is a consumable, so periodic replacement is required. The main reason for the replacement is: wear of the teeth of a sprocket with a saw chain. If the drum is monolithic, then during a long operation chain just cuts out a star, and you need to change the whole drum. On some chainsaws, the clutch drum has a replaceable crown, which also wears out. In this case, only the crown, the drum, if it is in good condition, remains for further use.

Many owners did not think about how to remove clutch on a chain saw on their own, because they have the opportunity to contact the service. But this possibility is not at all, for this we publish this article, in which we will explain the step by step how to remove a star from a chainsaw.

This operation is not a difficult task if you have tools and details. In the article, for example, all actions are performed using the Echo CS-3500 chainsaw, all operations to replace the clutch drum for other chain saws are similar.

How to remove a chain from a chainsaw

Like a chainsaw: Instructions and recommendations

One of the most important points of proper technical operation is the care of the chain. You need to know how Tighten the chain on a chainsaw, how to grind it and lubricate it. It is also very important to have an idea of ​​its characteristics. This knowledge can be very useful if you need.

Chain function and its correct tension

The correct position and tension of the chain chain is very important not only for normal work, but also for the safety of the person who works with it, as well as around it. If the chain has improper tension, then during operation it can accidentally fly away, which will most likely cause a breakdown of not only the chain itself, but the entire chainsaw. However, this is undesirable, even if the chain is stretched too much. This can also have negative consequences in the form of an increase in the load on the engine, which in the future will lead to its Rapid refusal and reduce the general service life of the chainsaw. The chain has one very important property: it fixes the tire, which prevents its arbitrary movement. Therefore, special attention should be paid to the chain.

Select the chain correctly

The chain malfunction is often found, therefore, before you ask yourself how to tighten the chainsaw, you need to know which chain is suitable for this model of the chainsaw. The main criterion for choosing is its step. Step. Distance between his teeth. The distance that it is chosen between the nearest teeth is measured in inches. The most common are 0.325, 0.375 and 0.404 inches. Information about the step can be found in the operating instructions for a particular model of chain saws, and this depends primarily on the purpose of the tool.

Each saw has its own specific step, exclusion. These are only professional tools that are universal. The chain step also depends on the engine power. The more powerful the chainsaws are, the greater its height and the more difficult it is to keep it when working. For example, compact low.Power chainsaw “Patriot” has a step 0.325. However, there are more powerful models. One of them. German Shtil in steps 0.404. This, as we see, is more than the chainsaw “Patriot”.

Step. One of the most important characteristics of the parameters of the scheme. This means that you should not choose a chain with a big step for a chainsaw with low energy consumption. This may not only not go out, but also disable the tool.

The importance of the correct configuration of the chain

The normal operation of the chainsaw causes vibrations that can significantly weaken the tension of the chain with blades or nuts designed to fasten it. The chain is stretched during intensive use and is poorly fixed on the teeth of chain saws, which can create unsafe conditions for the operator. The correct operation of the tool includes checking all nuts and bolts before and during use to ensure security. If the chain nuts are too free on the teeth of the saw, you most likely need to correctly pull out the chain, and then tighten the blade.

Before starting work, always remember your own safety and use protective leather gloves and goggles. The chainsaw should be placed on a flat surface, for example, on a workbench or table. Before using it, you must completely cool the engine. Then, to prevent a random run of the saw, remove the wire from the spark plug fork. Now you can start setting up the chain.

How to pull a chain on a chain saw with your own force

It’s not difficult to do, the main thing. Remember your own security. So, how to put a chain on a chainsaw correctly? Stand in front of a chainsaw, face you with a blade. Get the tip of the saw disk with one hand and slightly lift. Tightly insert a screwdriver with a flat head into the adjusting screw, which is located to the right of the blade when you look at the saw disk. Turn the screw clockwise to either counterclockwise to reduce it accordingly. Take the chain in one hand and pull it around the blade. The tension is correct if it is slightly weakened, pulling in the direction of the blade and at the same time tightly adjacent to it.

If so, further adjustment of the chain on a chain saw may not be required. If not, then you need to configure it. Loosen or tighten the adjusting screw to get the right landing. Keep the tip of the chainsaw blades with one hand. Tighten both clamping nuts of the blades on the left side using the repair kit or the adjustable key. Place the spark plugs wire in place and press it tightly.

Necessary tools

When buying a chainsaw is often equipped with a tool for its maintenance. You need to configure the diagram. It has the following look: at one end there is a screwdriver with a flat head, and on the other. The key that approaches the blades. To understand how Tighten the chain chain saw, cm. Installation instructions for this saw model.

Chapter 5: Adjusting Your Chainsaw’s Chain Tension

Security measures

When using a chainsaw, you should use personal protective equipment, including protection of the eyes and hearing, leather gloves and a helmet.

To ensure safety when working with a chainsaw, it is advisable to have a nearby person who can help if necessary.

Sharpening of chains

Work begins with weakening the tension of the saw chain. To do this, you need a slotted screwdriver, which should be turned on several full revolutions counterclockwise adjusting screw. Access to the latter is through a special hole in the clutch cover (a number of models on this cover contains a clutch clutch block (emergency brake).

Then we unscrew the two nuts from the bolts with an open or united key, which fix the lid and tire. Carefully remove the lid.

OREGON Chain Sharpening

To shorten the chain, one cutting link should be removed from it. After the fulfillment of this condition, it can again be regulated by the existing tension mechanism.

The choice is visually made. Determine a tooth that is as stuck and deformed in the process (for example, “caught” a nail or hairpin). Then we clarify the step of the chain to be shortened. You can do this correctly in several ways:

  • On the nameplate fixed on the saw chain;
  • According to information on the box (if it is preserved);
  • We measure the roulette or caliper.

To enter the table, you will need to perform one of three measurements. They are absolutely equivalent. Therefore, choose anyone at your discretion:

Divide the resulting value (in millimeters) by 2. The private will indicate one step in your circuit in millimeters. By the table, transfer it to inches.

  • The second option provides for the measurement of the distance between the five rivets. The resulting value is required to be divided into 4;
  • The third option, between the family (divide by six).

The resulting value, most often, will not coincide with those that are affixed in the table. Therefore, choose a tabular value as close to the results of your measurement.

If you work with household chainsaws of any manufacturer, then, with a probability of 95%, you will receive one of two values: 8.25 mm, which corresponds to 0.325 ”, or 9.30 mm (3/8 “). This is the most common step for the saw chains of unprofessional chainsaw models.

It must be prepared in advance. To carry out repair work (if there is a similar possibility), it is recommended to purchase a repair kit. This decision will ensure the maximum quality of work. Its cost does not exceed 250 rubles. For this money, you get 30 new connecting links consisting of two parts: the main (with the pins of future rivets) and the response (with holes for them).

In the absence of the opportunity to buy a repair kit, you can use the links from the second.Hand chain and rivets made independently. With certain skills, their quality and durability will be comparable to factory analogues.

change, chain, determine, degree, tension

Some masters manage to re.Use rivets removed from a shortened circuit. However, in such cases, most often, the walls of the connecting links have to be made more subtle. Therefore, this option can be used for short.Term operation of the saw in extreme cases.

  • 6 rivets;
  • 2 shanks;
  • 1 cutting tooth (selected by you);
  • 1 Sprinkled depth limiter.
  • On the removed area, you will need to cut 1 and 6 rivets (preferably on both sides).
  • The procedure guaranteeing the minimum probability of damage to the disconnected links is to steal the head of the riveting with a file (file);
  • You can cut it off using a hammer, a chisel (a chain is pre.Fixed in a grip);
  • Use a special nozzle for an electric drill, an angle grinding machine (grinder), an emery circle.

The use of mechanisms will allow this to do this much faster. However, such a solution has two significant deficiencies.

Firstly, the metal, with such processing, is significantly heated, which reduces its strength characteristics (the probability of a chain is being torn over one of the two remaining links in contact from 1 or 6 rivets).

After removing the external protrusions, the rivet is knocked out of the landing hole using a beard. It is recommended to slightly bend the side sides of the link.

If you need to shorten the original chain of the desired brand, no questions arise. And if you shorten and install a chain for a saw of a different model, you need to take into account the following.

See also  How to sharpen a chain on a chainsaw with your hands

It is necessary to pre.Calculate the number of remaining links in such a way that the number of guide protrusions located on the inside of the saw chain is combined with the size of the leading jelly of the saw.

To remove the rivets used to connect the elements of the chain, a pier is used, representing a small mechanical press of small sizes. The main elements of the design of this machine for the creep are:

Inside is the eccentric mechanism driven by the handle, which can be installed on the right or left on the case. In its original position, it is located in the extreme upper position (perpendicular to the supporting surface). Has a special limiter that allows it to deviate from the horizontal no more than 95%.

The piston rod is connected to the patching holder with an eccentric. Moving down, it easily squeezes the rivet without damaging the walls of the link.

Be sure to make sure that the machine has a punch of different sizes in the kit (rivets of various diameters are used to connect the structural elements of the saw chain, and each rod is designed only for one type).

When working, it should be monitored so that the diameter of the holes available in the sidewalls of the links coincides with a similar size of the punch.

When laying a disconnected circuit on the anvil, it is necessary to exclude the contact of its cutting part from the last. Only the shanks should contact her.

This question, with the apparent simplicity of the answer, can cause serious problems with the implementation. It is clear that riveting is required. But on free sale, even in specialized stores, they are rare quite rarely. If you’re lucky, you can find a repair kit, the links in which correspond to the size of the chain of your chainship (option, electric saw). But the chance to make such a purchase is small. Therefore, you have to consider alternative options for making rivets. There are not many of them:

Algorithm for mounting the cutting thread of the chainsaw

The leisurely installation of the chain takes no more than 30 minutes, provided that the correct and fixed installation of spare parts. The algorithm for installing the chain of the chainsaw consists of 8 steps:

  • It will be necessary to prepare a flat surface. This will avoid a curve of setting spare parts and the chain itself, and will also reduce the loss of fasteners to a minimum. First you need to lay out the tire and chain parallel to each other.
  • Remove the protection of the star. For old models, the fasteners of protecting the stars are made in the form of a lamb, which is not difficult to unscrew. For newer models of chainsaws, you need a wrench (most often by 10).
  • The drive asterisk of the chainsaw at the base of the guide tire must be unscated to the right to the right.
  • The links are applied to each fixing groove of the guide tires in a sequential order (link behind the link). The chain of the chainsaw is installed on top of the guide so that the tires are always on top, while the chain is from the bottom.
  • We install the tire and chain of the chainsaw on the leading star.
  • Set back the protective cover of the leading star. During the installation, it is important to make sure that the star itself stands smoothly and without a backlash.
  • We check the position of the guides that should be in special gutters.
  • We check how much the chain is fixed on the tire and in the chainsaw itself.

After the completion of this algorithm, the tension of the circuit itself remains. But before moving on to this procedure, you should make sure in the correct position of the chain. Otherwise, either you will have to repeat the algorithm again (up to the separation of the tire and chain).

Complete check

Usually the saw chain is changed in case of its extreme wear, when sharpening or repair is already useless.

Going to the store for a new component part, it is necessary to arm yourself with the following recommendations:

  • Changing any part of the electric saw, it is advisable to buy a product of the same manufacturer as the tool itself. This guarantees the greatest compliance.
  • It is important to take into account the type of tasks to solve. For significant loads, chains with 3/8 inch steps are designed. If the saw is rarely used, 0.325 inches will be enough.
  • The angle of sharpening of the teeth is of great importance: the cut of large volumes of dry wood is more convenient to carry out cutting edges with a sharpening angle of 30 degrees. To work with raw or freezing material, sharpening of 10 degrees is more suitable. The same applies to longitudinal sawing. A small angle of sharpening in such cases significantly reduces the degree of wear of the cutting device.
  • When choosing a chain length, you need to FOCUS on the dimensions of the tire.

How to pull a chain on a chainsaw

Before pulling the chain, refer to the instructions. It is spelled out in detail how and what you need to pull it. Depending on the model, the tension may vary. If there is no instructions or it is in another language, use our methods. They will be below.

Consider two types of chainsaws. Classic and with a tension adjustment handle.

  • Take the key from the kit, its shape resembles the letter T. The key has two work sides: one for unscrewing the nuts, the second. A screwdriver. To rotate the tension bolt.
  • First loosen the nuts of the lid, but do not unscrew them.
  • The second side (screwdriver) rotate the tension adjustment screw. It is located near the nuts.
  • Scroll the screw clockwise until the sagging of the chain from below is about five millimeters.
  • Twist the nuts.

Such models are less popular. They are put only on expensive equipment. On the side of the cover is the handle, during the rotation of which the chain will be pulled or weakened. Close. Tension, against. Weakening. Again, get sagging no more than 5 millimeters.

Before starting work, you need to check once again how the chain is stretched:

It should sag by ± 5 millimeters. Check with your hand how it goes. Scroll it. The course should be easy.

Worst of all, if you pulled the chain. Weakly stretched chains fly quickly and make themselves felt. The tattered chains do not make themselves felt immediately. You may not even notice the difference for a long time, but the wear of the details will increase.

Is it possible to shorten the chain yourself

In the case when the chain of the chainsaw was so stretched so that it is no longer pulled, there is a need to reduce its length.

You can Build a saw element, adding new links that can be purchased separately or remove from a similar. In stores you can see a chain for a chainsaw wound on the bays, which is sold for a meter. In general, repairs of chains for chainsaws can be made at home, since it is not difficult to find all the components for it.

How to remove a rivet

To change the chain elements or shorten it, you need to separate the links as follows. Fix the chain element in the vice and Stop rivets, namely, their protruding parts. To do this, you can use a file or file. Make sure that the side parts of the link are not stuck.

Using the beard (how it looks shown in the photo below), knock out the rivet.

There is another option for separation of links. This does not need to grind the hats of rivets. Place the link, namely its rivet, over any hole in the metal or above slightly divorced viges. Next, you should put a locksmith beard on a rivet hat and hit it several times with a hammer.

Continue to knock out both rivets alternately, since they are rigidly fixed by the opposite part of the link. Gradually rivets will begin to leave the upper part of the link, and it will be disconnected.

How to combine links

To begin with, you need to purchase links in a specialized store, suitable for the type of chain you have. You will have to do this if you grind the rivets when disassembling a chain element. Then it will be required The correct assembly of the link Taking into account the arrows indicated on it. Put the assembled element on the anvil and rivet rivets on the hammer with a slight beat of the hammer.

Some craftsmen advise connecting links using welding. This method is suitable if the rivets were worn by a file. But first you need to experiment on any iron to choose the right welding mode.

Welding must be carried out with a shortened and thin electrode. The rivet is welded to the lateral part of the link, and the excess metal is removed by a file. The only drawback of this method is overheating of the metal from which the chain elements are made. As mentioned above, due to overheating, the wear resistance of the links may decrease.
