How to make an electric chainsaw with their own hands

Electric chainsaw with your own hands: safety equipment, tips from professionals

The success of any construction directly depends on the quality of materials and tools. But sometimes it happens that the necessary equipment is not at hand, and to buy in the near future is not possible. Thanks to improvised means to mount the tool is quite realistic by your own efforts. In this article we will talk about how to make an electric chainsaw.

What is an electric chainsaw

An electric chainsaw is essentially the equivalent of a chainsaw, which is used to trim any type of wood. The tool is in demand in small households and industry. The device includes the following elements:

direct drive or bevel gearbox (depending on the location of the motor);

brake assembly, including thermal relay and protective shield;

How to make an electric chainsaw with your own hands

To assemble a chain saw, a variety of tools and materials will be suitable. One option involves the use of an angle grinder with a power of 1800 watts. Also needed:

A set of accessories, including a chain and a bar;

Stages of assembling a chain saw

Make holes in the bottom of the metal casing of the device;

from a sheet of metal (thickness 5-7 mm) to cut a bracket (the shape of the part is a circle with a beveled one side, two holes for bolts to mount the saw and one large hole corresponding to the diameter of the shaft of the angle grinder);

With the help of bolts to fasten the bracket to the guard of the angle grinder (where the holes were previously made);

Fix the guide behind the bracket ties;

To reduce the risk of injury, make sure you put on and straighten the chain, tighten the bolts on the bracket securely, weld the joints for extra strength;

Safety Precautions for Working with the Saw

The electric saw is sufficiently powerful and can cause injury to the operator while working. Real cases of cut toes and other body parts show increased danger, so do not ignore the cautionary rules.

Before turning on the saw, check that it is in good working order, that the electric cable is intact, and that the oil level is correct.

Work only when you are sober. Do not use the tool while feeling unwell or after taking strong medications.

Wear close-fitting clothing to prevent the ends of the chain from getting caught in the working area. Wear proper footwear that covers all the way down to the ankle. Goggles are recommended to protect your eyes from chips and dust.

Hold the saw with both hands when working.

The saw’s torso must be turned away from the cutting plane. You only need to move the tool slightly to the side.

Professional advice

Masters advise to choose the transverse location of the motor when assembling the electric saw. This option allows you to comfortably make a cut of wood, less fatiguing in the process of work.

When choosing the motor power, the purpose of the electric saw is taken into account. For summer cottage jobs and small households, a motor of 1800-2000 watts is suitable. A more powerful device is appropriate to use in large-scale construction. If the power indicator is small relative to operating conditions, the tool will overheat during operation.

Developing a drawing of a home-built electric saw, a system of start interlocking should be foreseen. This prevents unintentional starting.

When operating the saw, it is recommended to constantly monitor the oil level to prevent rapid wear and tear of the unit. Consumption rate is 1 liter of oil per hour.

Equipping a homemade design with a chain brake will save when working with an electric saw from the backfire, which occurs as a result of the resistance of the wood with the working part of the tool.

After each cycle of operation the electric saw has to be cleaned and lubricated. Also it is necessary to check the degree of tightening of connection nuts, so that in the process of operation the construction does not fall apart and cause harm to health.

Making a hand saw

Before we begin to understand how to make complex structures for sawing wood, it is a good idea to understand how to make a hand saw. This product is a tool in the form of:

The first one can be made from carbon steel U7 or U8 and a wooden bar. Carbon steel could be replaced by a worn disc, but in this case the “tail” would be short.

• A workpiece is drawn on a sheet of metal;
• At a distance of 5 mm from the lines, the workpiece is stamped with a core or drilled to form multiple holes;
• Between the holes, metal is cut with a chisel;
• The workpiece is separated from the sheet to mark the teeth;
• Between the teeth it is necessary to create slots, so that the finished “sharps” can be bent in different directions with a pair of pliers;
• A handle is cut from a bar and polished for subsequent attachment to the tail.

If it is necessary to make a manual gasoline or electric saw, an angle grinder is taken as a working mechanism.

In the latter, the protective guard is replaced by a semicircle welded to each other with a nose under the chain, which only remains to be planted on the specified plane.

Cordless chainsaw. characteristics, models

The cordless chainsaw combines the strengths of an electric and the mobility of a gasoline-powered tool. The use of battery power in power-hungry equipment was made possible by the development of a battery with high power but low weight. The tool works without harmful emissions and with low noise. In countries where environmental considerations dominate production processes, even forestry professionals are switching to cordless chainsaws.

Principle of chain saws, requirements for cordless models

A cordless chainsaw has a number of advantages over gasoline and corded models:

• mobility like a gasoline-powered tool;
• minimal noise, like a mains appliance;
• smooth and easy start-up;
• no exhaust and no risk of flammable material;
• no need for refueling and maintenance of the combustion system;
• easy safe transport of the tool.

However, the cordless tool is expensive, in terms of power is inferior to gasoline models, equal in price.

Like other chainsaws, cordless chainsaws are divided by intensity of use into residential, all-purpose and professional. The more work a cordless chainsaw can do, the heavier and more expensive it will be.

Basically, all tools are equipped with lithium-ion batteries with the lowest terminal voltage of 18 V, but more often with two sets of batteries providing 36 V.

Choosing a tool, you should be guided by the power of the motor, the length of the bar and the location of the motor. The choice is determined by a comfortable grip and a comfortable body position when working. Do not buy a saw without an accidental start lock button.

electric saw from an angle grinder with their own hands. options for making

Circular saws are indispensable tools for households. Thanks to their technical and functional properties, no furniture production or carpentry shop today can do without them.

And in private households, there are also many tasks that can be more effectively carried out with them. The only thing that limits their use today is the cost, which increases every year, as does the need for them by man.

One way to overcome this barrier and get hold of such a versatile helper is to assemble a homemade circular saw,

Given the load and duration of the working cycle of electric saws, for their home production will require an equally reliable basic electric device.

Folk craftsmen recommend using an angle grinder or angle grinder, which almost everyone has.

Its traction potential will be enough for sawing wood, dissecting planks into slats and other tasks that most users set for it. Let’s look at a few ways how to make an electric saw at home from an angle grinder.

Electric circular saw with your own hands: the easiest way to make

In order to start assembling a self-made saw, you will need:

• metal clamps;
• electric drill;
• toothed disc;
• Several pieces of metal angle;
• bolt ties of M3 or M5 modifications;
• Serviceable gearbox;
• rods of high-strength steel;
• wrench.

As the power base of the future construct will be the motor from the household angle grinder.

Step by step procedure

• from the angle grinder previously dismantle the disk that was installed before;
• Take a disk with teeth for woodworking, which is tightened with corners. Leaves a gap of a few millimeters, which are regulated by a coupler of bolts;
• The body of the angle grinder. the future of the electric saw is clamped. In the bottom of the tool is passed double metal strip with a thickness of not less than 1.5 mm;
• The gearbox of the angle grinder is disassembled beforehand. Holes must be made in it to fix the handle. The last part can be made of a metal tube, the shape of which should be slightly rounded;
• To adjust the gaps between the side stop and the base surface, 4 holes are drilled in the gearbox for screwing in the bolts;
• the handle is bolted to the gearbox. Its end that protrudes from the saw is held horizontally, holes are drilled and the axle is fed in.

In the case of a D-shaped handle, you must install an adapter between the handle and the gearbox. a tube of thick-walled metal;

When supplementing such an electric saw from an angle grinder with your own hands with a stationary base made of particle board or stable plywood, you can make a stationary circular electric saw for a workbench or work table.

In both variants it is important not to make a wrong choice of blade and to calculate the correct gear ratio. It is desirable to orient on single-phase asynchronous motors, which are installed on the majority of angle grinders.

Three-phase motor systems, which can also take place in such a design, should not be used without additional capacitors. A separate button can be brought out as a starting capacitor.

In this variant, you will need to think about additional grounding and check the electrical safety of self-made.

Electric chainsaw from an angle grinder: step-by-step instructions

In order to recreate a chain saw on the basis of a working angle grinder, we will need:

• the angle grinder itself;
• drive sprocket, which it is best to buy new, but if there is a serviceable part from the old saw, you can be limited to a used version;
• Metal to create a bracket on which to connect the guide rail;
• a set of sawing headsets from the bar and chain;
• a set of tools, including a drill;
• bolts.
• unscrew the saw blade from the angle grinder;
• make holes in the bottom of the metal casing of the device;
• bolt the bracket to the protective shield;

• on the motor shaft screw the sprocket;

• behind the ties of the bracket fasten the guide rail;
• After the chain is put on and straightened out, the bolts of the bracket are tightly secured.

Advantages and disadvantages of homemade electric saws from an angle grinder

Electric saws, which today you can not only buy in the store, but also make at home, in addition to their main advantage. low-cost for their production, have a lot of weaknesses. Namely:

• low level of safety for the health and life of the operator working. in self-made saws there is no protection against kickback, which in the factory electric saws is taken by the inertia brake of the chain. And this increases the likelihood of injury and maiming;
• durability of the tire-chain elements due to the lack of automatic lubrication. The only way out in this situation will be to periodically dip the homemade saw into a container of chain oil;
• high risk of overheating of the motor from the angle grinder due to overloads and prolonged operation.

Electric saw from the angle grinder with their own hands. options for making

Electric circular saws are extremely necessary tools for the household. Thanks to its technical and functional properties, today no furniture production or carpentry shop can do without it.

And in private households there are many tasks that are more suitable for them. The only thing that limits their use today is the cost, which increases every year, as well as human need for them.

One way to overcome this barrier and get hold of such a universal helper is to assemble a homemade circular saw,

Given the load and duty cycle of electric saws, for their home production will require no less reliable basic electric device.

Folk craftsmen advise as him to use angle grinder or angle grinder, which is almost everyone.

Its pulling capacity will be sufficient for sawing wood, splitting logs into slats, and other tasks that most users set it to do. Let’s consider several ways, how to make an electric saw at home from an angle grinder.

Electric circular saw with their own hands: the easiest way to make

In order to begin assembling the self-made saw, you will need:

• metal clamps;
• electric drill;
• toothed disc;
• several pieces of metal angle;
• bolt ties of M3 or M5 modifications
• serviceable gearbox;
• rods of high-strength steel;
• wrench.

As the power base of the future construct will be the motor from the household angle grinder.

The course of the work, step by step

• from the angle grinder previously dismantle the disk installed before;
• we take a disk with teeth for woodworking, which is tightened with angle bars. Leave a gap of a few millimeters, which are regulated by a coupler of bolts;
• the body of the angle grinder. the future power saw is tightened with clamps. A double metal strip with a thickness of at least 1.5 mm is passed through the bottom of the tool;
• the gearbox of the angle grinder is disassembled beforehand. In it it is necessary to make holes for fixing the handle. The last part can be made of metal tube, which shape should be slightly rounded;
• to adjust the spaces between the side stop and the base surface 4 holes are drilled in the gearbox for screwing screws;
• The handle is bolted to the gearbox. Its end that protrudes outward on the wire saw is positioned horizontally, holes are drilled, and the axis is fed.

In case the handle will be D-shaped, an adapter. a tube of thick-walled metal. is installed between the handle and the gearbox;

When supplementing such an electric saw from an angle grinder with your own hands with a stationary base made of wood chipboard or stable plywood, you can make a stationary circular electric saw for a workbench or work table.

In both cases, it is very important not to make a mistake with the choice of disc and correctly calculate the gear ratio. It is desirable to focus on single-phase asynchronous motors, which are equipped with the majority of angle grinders.

Three-phase motor systems, which can also have a place in a similar design, should not be used without additional capacitors. A separate button can be brought out as a starting capacitor.

In this version, you will need to think about additional grounding and check the electrical safety of self-made.

Electric chainsaw from angle grinder: step by step instructions

In order to recreate an electric chainsaw based on a working angle grinder, we will need:

• the angle grinder itself;
• drive sprocket, which it is best to buy new, but in the presence of serviceable spare parts from the old saw, you can limit yourself to a second-hand version;
• metal to create a bracket on which to connect the rail;
• a set of sawing accessories from the bar and chain;
• a set of tools, including a drill;
• bolts.
• unscrew the saw blade from the angle grinder;
• make holes in the bottom of the metal casing of the device;
• bolt the bracket to the protective shield;

• a sprocket is screwed on the motor shaft;

• behind the ties of the bracket fix the guide rail;
• After the chain is put on and straightened out, the bracket bolts are locked tightly.

Advantages and disadvantages of homemade electric saws from the angle grinder

Electric saws, which today you can not only buy in the store, but also make at home, in addition to its main advantage. low-cost for their production, have a lot of weaknesses. Namely:

• low level of safety for the health and life of the operator working. in self-made saws there is no protection from kickback, which in the factory electric saws is taken by the inertia brake of the chain. And this increases the likelihood of injury and maiming;
• the short durability of tyre-chain elements due to the lack of automatic lubrication. The only way out in this situation will be to periodically dip the homemade saw in a container of chain oil;
• high risk of overheating of the motor from the angle grinder due to overload and prolonged use.

Working with the saw and angle grinder

Before you make a circular saw yourself, you should try making it from other tools. The process is most often organized with an angle grinder, t.к. it can be reworked much faster and easier than any other analogues.

The simplest option is the best way to spoil the tool. It will be necessary to screw the tool to the base with metal self-tapping screws. If you want, you can make through holes with a drill and tighten with bolts and nuts, which will be much more reliable in operation, t.к. the tool will no longer tear the threads in case of severe tension. The only nuance to be considered is the factory unbalance of the tool, because of which it will be necessary to fix it most carefully, so that there was not even a small chance of movement.

If you want you can complicate this design, in addition, it will save the tool from unnecessary interference inside. For fixing you will need steel clamps, which will encircle the tool in 3-4 points and then be fixed to the bolts on 2 sides. This design is very reliable, but you should pay special attention to the quality of fixation to avoid even small misunderstandings.

For those cases where the tool is made stationary, you can use more powerful options angle grinder. Angle grinder itself is attached to the reduction gearbox with bolts or self-tapping screws (depends on the ability to make a joint without damaging the tool, because sometimes the mounting locations do not match), then they are installed together on the table top and screwed in the highest quality.

The most reliable way will be at the same time the most difficult, because you will need the support of the turner-miller. His task is only to mill a special part, which by its parameters would be suitable for the coupling of the angle grinder and the table top. This method of coupling is the most reliable, in addition, even microscopic movements are excluded, which is achieved not in every factory tool.

Take into account the fact that in any case the protective cover is removed and instead of it a self-made one is made of sheet steel. It will no longer be possible to use the attachment for the casing because it is used for coupling, and the self-made should be mounted directly to the table top. To make it, you need to cut out of sheet steel semicircle, which bends and clamps the tip with pliers. This design will withstand any surprises after it can be screwed on.

When choosing an angle grinder, you need to be very careful that the number of revolutions was small, and the power. high. If the speed will be more than 4500 rpm.\min, you have to use reduction gears, t.к. Otherwise the cutters will wear out very quickly.

It is very important to remember that under no circumstances should a circular grinder made from an angle grinder be converted backwards, because.к. For this reason people are hospitalized every day in all parts of the world with injuries of varying degrees of severity. Even if the angle grinder will be needed urgently, and there is no other option, it is better to be patient, for with a high probability will not save even the factory protection.

Saw modification

Electric saws and chain saws. a gift from the 20th century, which is very much in harmony with life, but there are situations when it is desirable to remake them, which is not easy enough. It should be taken into account in advance that this alteration is momentary, but if you want, you can repeat it over and over again without any damage (replacement will require some time).

To get a circular saw, you just need to weld a moving wheel at the end of the arm, and cut off the end itself. The wheel must perfectly follow the contour of the cut element, so the chain won’t get tight and fall off while moving.

A cutter adapter is attached to the side of the wheel. This adapter is removable, so that there are no difficulties in sawing with the chain.

If quality improvement the wheel will not harm performance chainsaw in the absence of cutters at this time. In addition, the basic operating speed is quite enough to do without serious third-party modifications.

Electric chainsaw from an angle grinder: step-by-step instructions

In order to recreate an electric chainsaw based on a working angle grinder, we will need:

• The angle grinder itself;
• drive sprocket, which it is best to buy new, but in the presence of serviceable spare part from the old saw can be limited to a used version;
• metal to create a bracket, on which the guide will be connected;
• a set of sawing accessories from the bar and chain;
• set of tools, including a drill;
• bolts.

• unscrew the saw blade from the angle grinder;
• make holes in the bottom of the metal casing of the device;
• bolts to attach the bracket to the protective shield;

Advantages and disadvantages of homemade electric saws from an angle grinder

Electric saws, which today you can not only buy in the store, but also make at home, in addition to its main advantage. the low cost of their production, have a lot of weaknesses. Specifically:

• low level of safety for the health and life of the operator working. in self-made saws there is no protection against kickback, which in the factory electric saws is taken by the inertial brake of the chain. And this increases the likelihood of injury and maiming;
• The durability of tire-chain elements due to the lack of automatic lubrication. The only way out in this situation will be to periodically dip the homemade saw in a container of chain oil;
• high risk of overheating the motor from the angle grinder due to overload and prolonged use.

With their own hands electric chainsaw from an angle grinder. assembly algorithm

Assembling a garden electric saw on the basis of household angle grinder gives the manufacturer an opportunity to get a light, small-sized and reliable enough unit for sawing small amounts of thin and medium-diameter wood. Peredelka angle grinder into electric saw does not require purchase of expensive spare parts. most of them can be found in the garage or use parts from old unwanted appliances.

How to turn an angle grinder into an electric saw by means of a nozzle adapter?

A special adapter nozzle is a product of the Chinese industry, which allows you to quickly convert a household angle grinder into the appropriate equipment. The accessories are sold as a set with or without the chain saw.

The adapter comes standard with a proprietary instruction manual, one or more cutting chains with protection, a guide bar and attachment, a plastic drive sprocket, a handle, a set of wrenches and fasteners, and an oil can.

The installation of the adapter consists of several steps:

• First, the operator must remove from the angle grinder its regular flange;
• Then the plastic drive sprocket from the adapter set must be installed instead. To fix the sprocket it is necessary to use the factory nut from the kit;
• After that, you must install the main unit, securing it to the gearbox with a coupler. For additional attachment of the unit, the operator must attach a screw on each side of the unit;
• At the end it remains to establish on a nozzle cutting elements from a complete set, as well as a handle, a protective cover and a regular safety for the hands of the operator.

For the saw headset to work, it will need to be lubricated with oil. Before starting to use the adapter, the operator must check the level of tension of the standard metal chain. Otherwise, the electric saw from the angle grinder will not be able to saw the wood, or will do it slowly and crooked.

Circular saw based on an angle grinder. preparation and manufacturing procedure

To assemble the garden tool, the constructor will need:

• Electric drill with a set of drills of different diameters;
• steel clamps;
• toothed disc;
• a pair of metal corners;
• Ties for bolt fasteners M3;
• gearbox ready for operation;
• steel bars;
• wrench.

To avoid mistakes during the manufacture of an electric saw from an angle grinder, you need to act in this order:

• First, you will need to remove the original cutting disc from the angle grinder;
• Then you need to take the toothed disc, designed for woodworking, and carefully tighten it with the corners. In this case, the manufacturer must leave a few millimeters of gap. Its size can be adjusted by bolting or coupler;
• Electric saw, made from an angle grinder with your own hands, must be equipped with a body. To do this, you will need to assemble a box of sheets of steel or plywood, and fasten them with clamps. The lower part of the housing will need to be fitted with a double steel band, which should be at least 1.5 mm thick;
• Then you need to disassemble the gearbox and make two small holes in it for mounting the handle. It can be pre-machined from a piece of metal. The shape of the handle should be slightly rounded;
• After that it will be necessary to drill 4 additional holes in the gearbox to adjust the necessary gaps between the main surface and the side stop of the electric saw;
• Then the handle must be attached to the gearbox. Its end, extended outside the case, should be installed in a horizontal position. Next, you will need to drill a few holes that will allow you to fix the axle;
• The remaining steel bars need to be cut into equal sections. The length of each of them should be 6 cm. The finished workpieces should be bent in the form of hinges;
• After that, you will need to install washers in the front of the electric saw stop, which will be necessary to adjust the gap.

The finished electric circular saw must be equipped with a sturdy frame that can withstand heavy, raw logs. It can be made from a piece of particle board, pre-coated with clear varnish.

How to make an electric saw out of an angle grinder?

To make a chain saw on the basis of the angle grinder the constructor will need:

• Fully serviceable and maintained angle grinder;
• Metal drive sprocket. it is best to buy a new part in advance;
• A piece of metal that will be needed to assemble the bracket. you need it to mount the guide;
• New tire and chain;
• Drill, welding machine and other equipment;
• a set of different sized bolt connections.

The algorithm of actions during the assembly of the electric saw from the angle grinder should be as follows:

• First necessary to remove the installed cutting disk from the angle grinder and make a small neat hole in the bottom of its protective casing. Next, you need to connect the protective shield to the bracket;
• After that, you need to screw the drive sprocket onto the power unit shaft of the angle grinder;
• Then you will need to install the cutting elements for the electric saw. They must be fastened behind the bracket ties;
• After installing and adjusting the chain tension it is necessary to tighten the fastening bolts of the metal bracket tightly.

Made by your own hands electric chainsaw from an angle grinder should be thoroughly tested. First you need to check the equipment when working at idle speed. If it does not make a noise or spark, you are ready to work with thin and medium-sized wood.

During the further operation of the electric saw on the basis of the angle grinder is important to remember that this homemade device is characterized by a low level of safety for the health of the operator and others. The machine has no mechanism to protect the user from kickback. Because of this, when working with the saw, there is always a risk of bodily injury.

In addition, it should not be forgotten that the power unit from the angle grinder often overheats. To prevent this, you need to take breaks every 10 minutes, giving the engine 5 minutes to cool down.

Making a circular saw

From the simple to the complex. making a circular saw, which is a hand tool with a cutting disk.

Larger quantities of wood require the disc to be clamped in order to cut more accurately. Therefore it is profitable to make a sawmill from a circular saw:

On a stable metal frame under the table it is necessary to cut through in the wood-fiber board for the trimmer line for the exit of the cutting base outside and holes for fastening directly to the saw (the disk should be located perpendicular to the side of the future table top).

After attaching the circular saw to the table top, it remains to attach a T-shaped product of two wooden boards to the latter from the outside (the long board is located along the circle protruding outside for smooth feeding of the workpiece “under the knife”, the short board is attached to the table end and gives the T-shaped fixation additional rigidity).

It remains only to take in hands the pusher of blanks, start the electric motor of the saw and get to work.

Band saw with my own hands

Friends, Hi. I want to present you a home-made saw, which I made about a year ago. This is a band saw for wood. Its design is not very complicated, and with the right skills it can be repeated by almost every master with a small set of tools.

Welding, grinder, jigsaw, drill, crowns, hand tools.

Next we need the side covers from the engines of old washing machines. They will serve as bearing housings. Cut off all the extra parts as shown in the photo. In the discs with a drill bit for 40 make the center hole. Next, we fold our package, set the lids on each side and use the drill to drill 4 holes. I wanted to glue all the plywood disks, but then I thought it would be superfluous and the 4 stud bolts M8 will give good rigidity. The same procedure has to be repeated with the upper wheel. In principle, the wheels are ready, but there is a nuance. They are terribly crooked and hit very hard. It took a long time to figure out how to level them and came to this solution. There is a threaded hole on caps, like M4. Rummaging through the stockpile, I found a pulley from an old washing machine.

From a 50×50 angle base was welded in the shape of a rectangle. On one of the short sides perpendicularly was welded stand, consisting of profile pipe 40×40 and reinforced with 50 angle.

All sawed on the spot, so the exact size will not say. On the frame in the middle welded a cross-member, to it a small rack and the top cross-member, to which will be attached to the axis of the wheel. I think the picture will be clear. If something is wrong, below the text will be a link to the video, there you can see everything in detail. I decided to weld the axle to the upper crossbar. By the way, I had machined the axis myself on my TV-16. I forgot to tell you that between the caps was installed spacer bushing, made from a water pipe. Adjusted the diameter of the axle to the inside diameter of the bearings and threaded one end.

The wheel is put on the axle and rests on the lug, on the other side it is tightened by the nut and secured by the washer. Welded the axle first, then attached the wheel department, leveled it and aligned it with the frame and vertical strut. Then the axle was finally welded. I temporarily installed the motor and put the belt on one side of the frame. Motor by the way from a washing machine automatic power of about 400 watts. On the channel there is a roller for making an Arduino-based controller for controlling these motors. This controller allows the speed to be adjusted to support the power. Also in the near future I will put here an article with the most detailed description on the assembly of such a controller. Give it a little time. I plugged it all in and slowly increased the speed. Everything rotates, nothing shakes, the bearings are not hot.

Rules of operation

Flexible and strong enough, such a saw is easy to use and does not require special skills from the user. It can be an indispensable helper at home. To use the product is equally convenient for both women and men, and it does not require great strength or to be trained. Work with any saw must not hurry and very carefully, regardless of whether it is mechanical or electric.

The user should know what not to do:

• Heat the working blade too much;
• The saw must open, not the other way around: this leads to jamming;
• to put the string at an angle;
• make jerky movements.

Cordless Saw With Their Own Hands

The lightweight electric sabre saw is used both for country houses and home construction.

One of the first saws invented by man was the onion saw. It was handmade, trivial to tune, and available to anyone. Could be blades. One inconvenience is that you have to hold it with two hands.

Then a hacksaw was invented that was simply held with one hand. And the second hand held the wood to be worked. To avoid fatigue of the working hand, the electric sabre saw replaced the hacksaw. For the cottage. simply an indispensable option. And branches from trees to cut, and wood to saw, and joinery work on the site can be performed without fatigue.

In essence, a sabre saw is an electrical jigsaw, but the hacksaw blade comes out the end like a chuck from an electric drill. Work much safer than a chainsaw, and cuts can be made as cleanly and accurately as with a circular saw.

What you need an electric chainsaw for?

Uses are almost unlimited. Using a variety of blades you can cut firewood, carefully cut blanks for window frames, saw an old door frame, cut a brick or asbestos cement pipe, saw a metal corner.

The main advantage of this tool is the ease of operation and its weight. Compact units are easy to hold with one hand, allowing you to work in awkward positions and reach the most hard-to-reach places.

Electric saw from the angle grinder with their own hands. options for making

Electric circular saws are essential tools for the home. Thanks to its technical and functional properties, today no furniture production or carpentry shop can do without it.

And in private households there are many tasks that would be more appropriate to solve with their participation. The only thing that limits their operation today is the cost, which is increasing every year, as well as the need for them man.

One way to overcome this barrier and to get such a universal helper is to assemble a home-made circular saw,

Given the load and duty cycle of electric saws, for their home production will require no less reliable basic electric device.

Folk craftsmen advise to use an angle grinder or angle grinder as it, which almost everyone has.

Its pulling potential will be enough for sawing wood, splitting logs into slats, and other tasks that most users. Consider a few ways, how to make an angle grinder electric saw at home.

Electric circular saw with your own hands: the easiest way to make

In order to start assembling the self-made machine, you will need:

• metal clamps;
• electric drill;
• toothed disk;
• Several pieces of metal angle;
• bolt ties of M3 or M5 modifications;
• serviceable gearbox;
• rods of high-strength steel;
• wrench.

As the power base of the future structure will be a motor from a household angle grinder.

The course of the work step by step

• from the angle grinder previously dismantle the disk, installed before;
• a disk with teeth for woodworking is taken, which is tightened with angle clamps. A gap of a few millimeters is left, which is regulated by a bolt tie;
• angle grinder’s body. the future electric saw is encased with clamps. At the bottom of the tool, a double metal strip with a thickness of at least 1.5 mm is passed through;
• the gearbox of the angle grinder is disassembled beforehand. Holes must be made in the gearbox to fasten the handle. The last part can be made of a metal tube, the shape of which should be slightly rounded;
• To adjust the gaps between the side stop and the base surface in the gearbox is drilled 4 holes for screwing screws;
• The handle is bolted to the gearbox. Its protruding end of the electric saw is given a horizontal position, the holes are drilled and the axis is fed.

If the handle will be D-shaped, an adapter. a tube of thick-walled metal. is installed between the handle and the gearbox;

When supplementing such an electric saw from an angle grinder with your own hands with a stationary base made of wood chipboard or stable plywood, you can make a stationary circular electric saw for a workbench or work table.

In both variants, it is very important not to make a mistake with the choice of disc and correctly calculate the gear ratio. It is desirable to focus on single-phase asynchronous motors, which are equipped with the majority of angle grinders.

Three-phase motor systems, which can also take place in such a design, should not be used without additional capacitors. A separate button can be brought out as a starting capacitor.

In such a variant it is necessary to think over an additional grounding and to check the electric safety of self-made machines.

Electric chainsaw from angle grinder: step by step instructions

In order to recreate a chain saw on the basis of a working angle grinder, we will need:

• the angle grinder itself;
• drive sprocket, which is best to buy new, but in the presence of serviceable spare part from the old saw can be limited to a used version;
• metal to create a bracket, on which the guide will be connected;
• a set of sawing accessories from the bar and chain;
• A set of tools, including a drill;
• bolts.
• unscrew the saw blade from the angle grinder;
• make holes in the bottom of the metal casing of the device;
• bolt the bracket to the faceplate;

• a sprocket is screwed on the motor shaft;

• behind the bracket ties fasten the guide rail;
• after the chain is put on and straightened out, the bracket bolts are fastened tightly.

Advantages and disadvantages of homemade electric saws from an angle grinder

Electric saws, which today you can not only buy in the store, but also make at home, in addition to its main advantage. low-cost for their production, have a lot of weaknesses. Namely:

• low level of safety for the health and life of the operator working. in self-made saws there is no protection against kickback, which in the factory electric saws is taken by the inertial brake of the chain. And this increases the chance of injury and maiming;
• The durability of the chain-and-track elements due to the lack of automatic lubrication. The only way out in this situation will be to periodically dip the homemade saw in a container of chain oil;
• high risk of overheating of the motor from the angle grinder due to overload and prolonged use.

A chainsaw with its own hands

Makeshift crosscut saw made by our own hands: detailed description of making a home-made machine with a step-by-step photo.

Greetings to readers of the site the Builder himself! I want to show you an interesting idea for making a crosscut saw, instead of the disk there is a guide bar from a chainsaw. This solution has several advantages over a chainsaw: no need to spend money on oil and gasoline for a chainsaw, there is an electric motor. The length of the bar allows you to cut large workpieces, it is more practical compared to the circular saw.

Materials for making a homemade electric saw:

The following photo shows the process of making a chain sabre saw.

Electric motor asynchronous 4000 rpm.

Putting the guide bar on the motor. The author assembled a simple frame for the motor from angle bar and steel plate. Saw-tooth sprocket is mounted on the motor shaft, according to the position of the sprocket attach the holder for the guide bar. A similar holder can be taken out of an old chainsaw, and most importantly, it already has an oil pump that will provide lubrication for the bar.

Assemble the frame for the machine, the base can be welded from the angle, the axle with bearings is installed on the base. To the axle mounts the platform in the form of a sheet of steel, already to this platform screws the motor.

Motor with guide bar, can be raised and lowered. To make it easier to lift the motor, the author installed a gas spring.

We make a handle of profile pipe, for which we will lower the motor, on the handle we put a pushbutton switch.

Homemade guide bar saw successfully passed the tests, quite successfully saws wood.

It is very important to work safely! Since the guide bar will be in dangerous proximity near hands and other parts of the body.

Here you can watch a video showing a crosscut saw in operation.
