Do-it-yourself pendulum saw for wood

DIY pendulum saw

A homemade pendulum saw made by a craftsman with his own hands: photo, detailed description , as well as a video showing the saw in action.

When working in a workshop, very often you need to cut off a straight corner, channel or profile pipe. I decided to make a homemade pendulum saw, the design should not take up much space in the garage and be mobile.

I would also like to say something about the engine. I looked at examples of machines, most recommend installing 3 kW motors, ideally connecting to a 3-phase network or through a tank to a single-phase one.

I had a 1.2 kW 1450 rpm engine, I decided to use it to make a machine, increase the speed on the circle with pulleys, so as not to lose the already small power, I used a frequency drive.

The circle size is 230, with the possibility of installing 300.

The manufacturing process of a pendulum saw is shown in the photo.

The rotor shaft from a burnt out engine was used for the pendulum assembly. I made the supports for the bearings from a water pipe.

The shaft and support were made by a turner. The frame for the engine and shaft is welded from a 40 x 40 mm profile pipe.

The table is made of a corner 45 x 45 mm and a profile pipe 40 x 40 mm.

There are 75 mm wheels on two legs of the table, and adjustable supports on the opposite legs.

The table top is covered with 2 mm steel sheet, the protective casing is made of 1.5 mm sheet

I’ll dwell a little on the frequency converter, the price for them starts from $100, I didn’t look at the specifications, and I don’t need it, because I wasn’t going to buy a ready-made one. I made a homemade frequency generator, I won’t describe it, there are diagrams and a detailed description on the Internet. I’ll just show you a couple of photos of what the one I made looks like.

Manufacturers of pendulum saws

The safest and most technologically advanced models are produced by the following companies:

Makita;
Corvette;
Bosch;
DeWALT;
Hitachi;
Metabo.

Pendulum saws are usually characterized by a fairly small cutting width. To increase this parameter, professional saws have a special traction function. On these machines, the working unit is mounted on rods.

Many manufacturers can expand the basic configuration by offering a wider table, however, if you need to work with larger materials, additional supports will not be superfluous.

1. For example, the Makita LF1000 miter saw has special folding stands that make it easier to work with.

The stable frame of pendulum saws holds the moving part. The bed itself has a round section for more convenient setting of the cutting angle.

If aluminum or magnesium alloy was used to make the frame, then such models are more reliable by default. These elements are not only highly durable and reliable, but also lightweight, so this miter saw is mobile.

2. The Corvette miter saw boasts the following advantages, which distinguishes it favorably from tools produced by competitors. The advantage of the Corvette is the presence of a laser pointer and longitudinal broach.

The latest models are even more improved, since they can increase the cut to 43 cm.

3. Pendulum saws from DeWALT, in turn, also offer an interesting solution - the unique XPS system.

It boils down to the fact that a shadow will be projected from the disk during operation, acting as additional lighting. Thanks to this, cutting is more accurate.

At the moment, there are many companies engaged in the production of pendulum saws for cutting building materials.

First of all, it is necessary to start from performance, that is, if infrequent work is planned, then you can choose the cheapest saws, in any case, they will have the main function in place.
And if the work must be highly accurate and professional, then you should start from more expensive models.

What are the benefits of a pendulum saw for wood?

A pendulum saw is an electric tool used to work on wood or metal. Using this device, you can accurately and quickly cut the workpiece into the required number of pieces. The tool performs cutting due to the reciprocating movements of the saw blade along the wood part.

A DIY pendulum saw for wood looks like a small machine on which the saw blade is mounted in a position perpendicular to the surface on a pendulum. The dimensions of the models vary depending on the power of the unit. With the help of a pendulum, the cutting disc is lowered or raised while cutting wood or iron.

Device of a disk cutting machine

Metal parts are made of hard steel alloys for more uniform and stable operation. The platform consists of a rigid base made of metal. The cutting machine can be stationary or removable; some types are equipped with a vice for securely holding the workpiece during cutting.

The disc is made of carbide steel or high-speed elements. Depending on the type of structure, a wheel with an abrasive surface is used, which allows you to process chamfers and edges from burrs. Stationary metal cutting machines use a gear drive to provide reliable connections and long-lasting performance.

Disc cutting machine diagram

The belt type of mechanical energy transmission is installed on portable devices in which weight is important. Low-power designs of the fourth category are connected directly to the disk mechanism.

How does a pendulum saw work?

Pendulum saws for wood are similar in principle to saws with a circular blade. The only difference between the two types of saws is that in pendulum saws the cutting blade moves during operation using a pendulum device, while in a circular model the blade remains stationary.

With this saw you can make precise and clean cuts at an angle of 90 degrees. Some models can cut at a different angle, with the saw blade in an inclined position.

When cutting metal or hardwood, you can use an abrasive disc. For different types of work, you can use replaceable disks of different configurations. Universal circular blades are also produced to work with any part material.

Any saw must be equipped with protective devices that reduce the risk of damage from a rapidly rotating saw blade.

The main disadvantages of these cutting saws:

sawing by hand requires a lot of effort, which leads to rapid fatigue;
the cutting model, like the jigsaw mechanism, can cut a limited thickness of the workpiece;
The device has low productivity, so it is used as additional equipment or for solving everyday problems.

Pendulum saws

The miter saw is designed for sawing wood blanks at a right, oblique angle or at an angle, as well as removing material from the blanks. In addition to wood, miter saws can also work with other materials (plastic, laminate, aluminum). They are used for carpentry, finishing, general construction and installation work. It is most often used in furniture making, flooring and frame production. The most commonly used saws are JET - JMS-10, ELMOS EMS 254, Festool KS 120 EB 230 B, AEG - PS 305 DG, BOSCH - GCM 12, DEWALT - DW 716, HITACHI - C10FCH2, MAKITA - LS 1040 F, Metabo - KS 216 LASERCUT.

When choosing a pendulum miter saw for infrequent and fairly simple work without much load, buy an inexpensive machine with a standard set of functions. And for complex work where the accuracy, accuracy and endurance of the device are important, it is necessary to buy a professional version and take into account the maximum dimensions of the workpieces, whether the machine has electronic adjustments, what the base is made of, to what extent it is possible to adjust the angles of inclination and rotation, whether there is a laser and backlighting , does it have a pulling function, etc.

In general, the device of a miter saw is quite simple: the working unit - a motor with a gearbox, a saw blade and a handle with a start button - are connected to the base using guides. Both commutator and asynchronous motors are installed on trimmers. The first is characterized by high torque, but requires regular maintenance and replacement of commutator brushes. The second one has no brushes and operates with less noise and lasts longer. Most often, the motor is located to the right of the working disk. However, on some machines it is moved back so that it does not block the view and does not interfere with inclined cuts (if the design allows for the working head to be tilted in both directions).

The motor drives the cutting disc through a gearbox. There are two types of transmission - gear or belt, each with corresponding advantages and disadvantages. The toothed gear prevents slipping under high loads. The belt makes less noise and dampens disk vibration, and this has a positive effect on the quality of operation and durability of the motor. However, the belt may fly off if there is a sudden change in load. There are miter saws without a gearbox: torque from the engine to the disk is transmitted directly, with this option a minimum of rubbing parts means maximum reliability, and the disadvantage is low torque. The pendulum saw has a relatively small cutting width, especially when working at an angle or slope. To increase the cutting width, the saw is equipped with a traction function like Metabo - KGS 303 Plus, MAKITA - LS 1216, HITACHI - C10FSH, DEWALT - DW 718, BOSCH - GCM 10 SD, JET - JSMS10L. With this feature, the working block of the trimmer is installed on two guides and the disk can move along the cutting line, while its cutting edges rotate away from the operator, so that during operation the flow of sawdust is directed to the side, and the disk also presses the workpiece against the stop.

When choosing a saw, pay attention to the tilting mechanism of the working unit: is it rigidly fixed or is it an integral part of the movable console. In the first case, the angular adjustment is set accurately and rigidly, and in the second, it is necessary to take into account the possible backlash of the carriage. The working part of the trimmer is installed on the frame. It has a round section that rotates when setting the cutting angle, and a rip fence consisting of two parts. Often frames are made from die-cast aluminum or magnesium alloy, which provides both strength and mobility due to reduced weight.

When making a cut, turn the table at an angle. The range of rotation angles is at least 45 degrees in both directions. Usually it is more, up to 60 degrees, and it can be different on the left and right sides. Often, the adjustment mechanisms are equipped with clamps for quickly setting the most commonly used angles (0, 15, 22.5, 30 and 45 degrees), which are set on a scale. The saw blade tilts, but not always. Typically, the shape of the opening for the cutting blade in the longitudinal stop corresponds to the type of tool. If it is one slot, then the saw cuts only vertically; if the right or left corner is cut, the saw head can be tilted in these directions. The usual head angle is 45 degrees, but on some models it is increased and reaches 47 degrees. This is due to the conditions of the potential application, such as uneven walls. The ability to limit the depth of cut is necessary, for example, when making grooves or trimming profiles.

Miter saws have electronic speed control to adjust the cutting process of various materials, maintaining a constant speed under load. Some miter saws are equipped with a laser precise guidance system that indicates the line of the intended cut.

There are pendulum miter saws with a table extension for working with long workpieces. Typically, such a table is a stop on two rods, which is mounted in special holes on the sides of the bed. For safety reasons, a protective disc guard and an electrodynamic brake are installed, which smoothly and quickly stops the engine after turning off the power. The security system also includes soft start; power-on blocking when replacing a disk; automatic shutdown in case of a stuck disk, protection against breakdown of the housing, position of control elements, the presence of a convenient and quick system for fixing the workpiece. There are saws that combine two functions - miter and sawing, for example ELMOS EMS 258, MAKITA - LH 1040. They are equipped with a sawing table placed on top. The saw is equipped with a riving knife with a protective blade guard and a guide.

The saw blades of a miter saw are selected depending on the material the saw can work with. The two main parameters of a saw blade are the outer and seat diameters. The internal one is usually 30 mm, and the external one is 210, 250 and 305 mm. There are also differences in the geometry and sharpening of the teeth, and the material of manufacture. One tooth configuration provides high speed for cross-cutting, another for longitudinal cutting, the third guarantees a cleaner and more accurate cut in a certain type of wood, and the fourth is suitable for working with plastic or aluminum. Some saw blades have "patterns" laser-etched into the blade to compensate for thermal deformation and to reduce noise during operation.

How do these saw models work?

The device can be classified as a circular model. The cutting disc is installed on a special fixed frame, and the machine itself is powered from the electrical network. The name “cutting” is explained by the fact that the cutting wheel moves down at the moment of cutting, and after completion of sawing it returns to its initial position.

The powerful cutting wheel of the saw is capable of separating not only wood or metal, but also porcelain, glass, plastic or tile. To cut wood, you can use a blade removed from a circular saw.

How it works

This type of cutting equipment falls under the category of circular cutting machines.
In its design, the cutting disc is mounted on a special frame, and the power source for the machine is the electrical network. The presence of the word “cutting” in the name indicates that the cutting disk is lowered during cutting, and after the end of the working cycle it returns to its original position. The powerful cutting blade allows you to make cuts in a wide range of materials - not only metal and wood, but also tile, plastic, glass and porcelain. To work with wood, you can install a blade used in circular saws on the machine.

How to make a pendulum machine yourself?

In order not to spend extra money on purchasing an expensive device, you can make such a tool yourself. A do-it-yourself pendulum saw for wood can be made using an electric drill, grinder or electric motor. With certain knowledge and skills, you can design your own model, which is not inferior in power and productivity to factory units.

To make such a saw with your own hands, you will need to study the drawings and instructions for assembling the mechanism. Follow the basic sequence:

take the electric motor from the grinder;
install the V-belt from the car in such a way as to transmit rotation from the motor to the spindle;
to secure the pendulum device, build a metal frame using metal with a square cross-section, or adapt the attachment to an electric drill;
Weld the spindle housing to one side of the frame, and fasten the electric motor to the other; make the shaft size as indicated in the drawing for assembling a hand-held pendulum saw;
you need to make a groove in the frame through which the rolling axis of the saw blade will pass; weld the frame so that the motor, rolling axis and spindle are parallel;
the protective case is best made from an iron sheet; Install the drive handle on the belt guard.

Working with metal is one of the most labor-intensive, the main reason for this is the high strength of the material. However, because of this distinctive property, it is almost impossible to do without metal products during construction - metal elements are required for almost every supporting structure, fastening system or stiffening frame. Therefore, in your arsenal of construction tools you need to have devices that allow you to easily cut metal, this is, for example, a pendulum saw for metal - making it yourself may not be too easy, but buying a branded saw will be too expensive - the price of such a saw will be rather high. Therefore, it is better to activate your inner engineering genius and still try to make the instrument yourself. Moreover, as practice shows, homemade tools allow you to avoid the disadvantages that are characteristic of factory models. However, first things first.

Do-it-yourself pendulum saw for wood - All about timber and woodworking

When working with metal or wood, the need often arises to make an even cut at a certain degree. It is almost impossible to do this the first time with an ordinary grinder; for these purposes it is worth using a pendulum saw.

A pendulum saw is a special type of tool that is designed to quickly and accurately cut various materials. Most often wood or metal.

It looks like a small machine with a cutting tool installed on it. The disc is attached to a pendulum-like device.

Thanks to this, the mechanism performs pendulum movements, that is, reciprocating, which allows you to make an even cut.

This saw can be considered a type of circular saw. The difference lies in the design . In a circular saw, the motor and disk are attached to the machine in a stationary state, while in a pendulum saw they move along with the mechanism.

Such a tool is an indispensable device in any production. The saw allows you to make precise cuts in almost any material at the desired angle. The cutting element is represented by an abrasive disc. With its help you can saw various metals, wooden blanks, plastic products, porcelain, earthenware and other materials.

This is a very dangerous tool, so its use is only possible if all safety rules are followed. For protection , such machines are equipped with a protection system. Increased safety is a must for both industrial and home use.

The cost varies across a wide price range, so it is easy to choose a model to suit your own requirements. If necessary, you can assemble such a saw yourself if you have the necessary materials.

For industrial production, models with an automatic disk movement mechanism are used. For home needs, a model with a manual mechanism is suitable.

Features of operation

For ease of use, it is recommended to pre-install a production table or workbench. It is desirable that such a table be height-adjustable and have sufficient area for storing workpieces and sawn parts.

Even for compact home models, the desktop area should be around 8 square meters. m. Approximate size - 2x4 meters. This allows you to cut workpieces up to 3 meters in size.

When using a pendulum saw, be sure to ensure safety, close the protective curtains and use personal protective equipment.

This is very important, because when cutting wood or metal, small wood or metal shavings fly out from under the working wheel.

When cutting metal workpieces, flammable liquids and materials should be removed from the workbench, as hot metal particles can cause a fire.

Advantages and disadvantages

Assessing the advantages and disadvantages , it is worth noting that there are much more advantages. These include:

Functionality. By changing the working blade and operating power, such a saw can be used for cutting workpieces made of various materials.
Quality. Most of these tools are made for professional use. Therefore, the quality and service life of such saws is increased.
Accuracy. The workpiece is cut very accurately at the required angle of inclination, which cannot be done using another tool.
Speed of work. Thanks to the design of the machine, you can cut a lot of workpieces in a short period of time. At the same time, changing the angle does not require spending a lot of effort and time.
Easy to maintain. Changing working tools is quite easy, and the necessary parts can be easily found in almost any hardware store.

The only disadvantages include the high cost of the tool. But when used professionally, it is compensated by properties and characteristics. It should also be noted the low quality of discs made by unscrupulous manufacturers. Therefore, when purchasing consumables, it is recommended to pay attention only to trusted manufacturers.

Saw with your own hands

To save money, you can assemble such a tool yourself, but it is only suitable for home use. To make it, you need to have a regular circular and the necessary materials (channel and corner).

The production of the frame is carried out by installing two channels, to which the base of the pendulum mechanism is welded. The grooves for installing bearings are produced in a turning shop for a small fee. Be sure to make protective covers, which can be made from thin sheet steel.

If you are not entirely confident in your abilities, then it is better to purchase a new pendulum saw to save your nerves, money and time.

A pendulum saw for metal and a pendulum saw for wood are practically no different. The only difference is the type of wheel used.

Every self-respecting owner, accustomed to doing everything with his own hands, strives to equip his home workshop as best as possible. And to work normally with wood, you need to have a good saw and preferably more than one. Today there are a lot of similar tools on the market, and it is often difficult for the average person to figure out what exactly he needs.

This article is devoted to the topic of choosing such a tool.

Photo of a manual circular saw.

First of all, it should be understood that all tools intended for cutting and processing wood can be divided into two main areas. These are hand saws or hacksaws and tools powered by an electric or some other drive.

Operating principle of a pendulum saw

A pendulum saw, also known as a miter saw, is a circular saw mounted on a frame and driven by electric current. Factory products have a special turning circle in their design, which allows you to use the saw as a miter box. However, this function is not always necessary, so in a homemade pendulum saw you can do without a turntable.

In general, such a saw is called a pendulum saw because its cutting mechanism rises and falls along the trajectory of the pendulum. That is, during the cutting process, the master lowers the cutting wheel onto the workpiece, and after cutting, raises it back.

With this saw you can cut a variety of materials:

To work with different materials you need to use different cutting elements. For example, to work with metal you need to use a special cutting disc, which can be taken from a grinder, and to saw wood you need a disc from a circular saw. That is, no additional equipment is required to work with different tools; for example, a saw for metal can quickly be converted into a pendulum saw for wood - you can replace the cutting element with your own hands in a matter of minutes.

Do-it-yourself pendulum saw based on a screwdriver

Hello, dear readers and DIYers! In this article, the author of the YouTube channel “Gökmen ALTUNTAŞ” will tell you how he made a very useful machine for his workshop.

This basic pendulum saw will be made from scrap plywood and boards. You don’t need any special tools to make it—you can get by with a hacksaw and a screwdriver. The materials are also the simplest.

Materials. — Sheet plywood — Spring — Wing nuts, bolts — Boards — Steel stud — Wood screws — Steel strip — PVA glue — Bearings.

Tools used by the author. — Screwdriver — Drilling machine — Wrenches — Clamps — Wood bits — Hammer, screwdriver — Electric jigsaw or wood saw.

Manufacturing process. The author begins by making the base of the machine and screws the side support to the sole.

Then installs two spacers.

He drills the necessary mounting holes in the rocker arms and racks of the future machine.

Pre-assembles the frame.

A slot is made at the front edge of the rocker arm, and a steel plate with two clamping washers and wing nuts is inserted.

He does the same operation with the lower rocker arm, clamping the blade between the washers.

A tension spring is installed between the rear edge and the post.

Tries the rack with rocker arms to the base.

Additionally, it installs a tension mechanism; it is designed to move the front parts of the rocker arms apart to tension the web.

Now the author begins to manufacture the eccentric, cutting out a couple of round timbers with a crown.

Drill a hole from the edge of one round piece and insert a bolt into it.

Now he makes two supports for the eccentric. In their upper part there are grooves for bearings.

Installs bearings and presses them.

These are the supports the author came up with.

Then he connects the supports to the eccentric using a bolt and nuts.

Now he is making the movable part of the mechanism, which will be attached to the lower rocker arm.

Assembles the eccentric and the moving part together.

Screws the support to the base.

Now screws the stand to the base, and to the side struts, and to the side support.

Then the craftsman cut out an arc and a semicircle from plywood, and screwed them to the bottom of the table, having previously coated the joints with glue. This will be part of the table tilt adjustment system.

I screwed a block with a hole to the back of the table according to class=”aligncenter” width=”1274″ height=”713″|fcw3qayjh5a| src=»https://usamodelkina.ru/uploads/posts/2019-02/1550595583_saw-212.jpg» class=»aligncenter» width=»1274″ height=»713″[/img] I installed a block with a bolt on the rack , put the table on it, then pulled the canvas.

I made a clamping nut from a furniture nut with teeth and a round piece of plywood. This is how the table tilt will be adjusted.

From a piece of rubber and a block with a wing bolt I made a system for clamping the screwdriver button. As the bolt is screwed in, you can adjust the engine speed by pressing the button with different amounts of force.

The author clamps the shaft in the chuck, and the machine is ready for work.

Now you can cut out various figures from plywood or wood.

Thanks to the author for a simple and useful machine for the workshop! Good mood, good luck, and interesting ideas to everyone! Source

How to make a pendulum saw with your own hands?

First of all, you need to purchase an engine. This can be any 1-phase electric motor, for example, from an electric grinder. You can also take a 3-phase one, but its power should be higher than that of a 1-phase one. The rotation of the engine can be transmitted to the spindle of the cutting body by a belt drive, for example, an automobile V-belt.

To mount the saw, you need to weld a square-section frame from metal; on one side, a housing for the spindle is welded to the frame, and on the other, a platform for mounting the motor. A groove should be provided in the frame through which an axis for swinging the saw will pass; it can be made from a piece of pipe. When welding the frame, you need to clearly ensure that the axes of the swing, motor and spindle are parallel to each other.

Protective covers for the cutting element and drive belt can be welded from sheet metal. The covers must be secured to the frame with screws. The belt guard must have a drive handle.

If everything is calculated correctly, the engine will outweigh the cutter and, when released, will be located between the supports of the spinal frame.

In principle, there is nothing difficult in making a pendulum saw with your own hands, you just need to make the correct drawing, carefully carry out all the work and reliably fasten all the parts together.

What is this?

The saw performs reciprocating movements during operation. The saber works exactly the same way.

A cutting pendulum electric saw is a fairly compact machine in size, where the cutting tool is a disk and is mounted vertically on a special pendulum.

The size of the device may vary depending on the model and power. The pendulum provides the ability to raise and lower the cutting blade when working on metal or wood.

The assortment is extensive, which allows the buyer to choose such popular saws as Makita, Zubr, PM 400, etc.

Device Features

Drawing of a typical saw device

Circular and pendulum saws have approximately the same principle of operation;
The main difference between the devices is that with a disk cutting tool and the motor are fixed motionless, while with a pendulum device they rise and fall due to the pendulum;
The cutting pendulum installation provides a high-precision cut at a right angle;
Additionally, tools such as PM 400, PM 55, Interskol, Zubr, Makita, KD 300, PM 70 and other representatives of the pendulum saw segment are capable of cutting at an angle;
Often, a cutting system for cutting wood or metal includes an abrasive disc;
The use of appropriate disks allows you to work efficiently. To process a particular product, you simply need to replace the blade;
The blade can also be universal, allowing you to cut all kinds of workpieces with one disc;
A modern cutting pendulum electric saw for cutting workpieces is distinguished by the fact that the cutting blade and disk can be replaced in the shortest possible time. This is what distinguishes the leaders of the segment in the person of PM 70, PM 55, KD 300, Zubr, Makita, Interskol, PM 400, etc.;
Each cutting tool must be equipped with protection systems. This is because the rotating cutting blade is potentially dangerous;
By choosing the desired size of the device, you can cut workpieces at home;
Manufacturers offer both household and industrial models.

Despite its fairly significant advantages, the pendulum cutting saw has several disadvantages.

For sawing, you have to apply significant force, as when using a grinder.
A cutting saw has certain restrictions on the width of the material being cut.
The device is not very productive, so it is often used as an auxiliary equipment in factories or home workshops.

The estimated price of devices for home use is from 12 to 40 thousand rubles.

How it works

To cut materials, you need to know exactly how a pendulum-type electric saw functions.

A pendulum saw can safely be called a circular saw. Here the circular machine is installed on a special frame;
The machine operates from the mains;
Factory models can be equipped with special turntables, due to which the device is used as a miter box. This function cannot be called necessary, but sometimes its relevance is in demand;
The electric cutting saw received its name due to the fact that the cutting blade is lowered by hand along a pendulum path onto the workpiece, and when the cutting is finished, it rises to its original position;
Depending on what blade is used, the size and power of the device, a factory-made or home-made electric saw can cut metal, wood, tiles, porcelain, plastic, glass, etc.;
Cutting discs are used to cut metal. They can be borrowed from an angle grinder;
If it is wood, a circular blade is used.

Do-it-yourself pendulum saw for wood

A pendulum saw for metal, in fact, is a cutting machine whose tasks include: cutting pipes, profiles, metal corners, at various angles.

The machine is a rigidly fixed frame, with a pendulum mechanism, which allows cutting to exactly the size and intended angle.

The majority of tools on the market are from Makita, which guarantees high quality and efficiency, but there are also products from lesser-known manufacturers.

Device

The pendulum feeding mechanism of the cutting tool involves a top-down working movement, through mechanical or manual control.

One of the advantages of a pendulum machine is the change in cutting angle, up to 45 degrees from the normal.

The working part of the machine is a circular saw; depending on the type, the machine can be single- or double-headed, depending on the number of cutting saws.

The circular saw located on a pendulum mechanism can be driven either manually by an employee or automatically.

are often installed on the machine for additional control of cutting accuracy, for example, the Makita LC1230 machine, in this case the cutting angle is changed by turning the handle.

Advantages and disadvantages

When fully equipped, the pendulum saw is absolutely safe and comfortable to use.

The dust collector collects abrasive elements and metal particles.

The clamp for securing the workpiece holds the part to be sawn and prevents the blade from skewing.

Advantages of pendulum cutting machines:

Multifunctional, it is enough to simply replace the saw blade.
High-quality, precise cutting of the workpiece, due to the precision of the pendulum installation, especially for professional tools from Makita.
High cutting speed, the pendulum cutting saw for metal works quite quickly.
Availability and ease of installation. Buying such a saw is quite simple; it is offered in almost all tool stores. If necessary, you can assemble a pendulum saw with your own hands.
Ease of maintenance and replacement of device elements and cutting discs. It is especially easy to change the saw blade.

Disadvantages: the only disadvantage of this type of machines is their high cost in professional performance. Thus, a Makita pendulum saw costs from 10 thousand rubles.

But at the same time, Makita tools are most valued by our industrialists.

Makita produces power tools and components, the same saw blades, of high quality and different prices, from household models to highly professional equipment.

Assembly saws

A special subtype of pendulum cutting machines is characterized by a simplified design and increased mobility. Assembly machines do not have a mechanism for turning the saw itself and cut the workpiece only along the normal.

The device in this case is as simplified as possible: a saw, a pendulum, a frame. Discs for cutting metal are usually abrasive; carbide is less commonly used.

The drive on a disk, in professional cutting machines, is usually belt driven, this allows you to reduce the load on the engine and avoid sudden jerks.

Due to the lack of rigid fastening of the pendulum and the workpiece, when working with cutting-off assembly machines, the following nuances must be taken into account:

Use a clamp to secure the workpiece while cutting.
At the moment of starting, the torque of the disk gives a strong push to the saw, take this into account.
When cutting with a mounting machine, a burr is formed on the workpiece, which must subsequently be removed.

To do this, it is enough to make a frame from a channel and an angle; you can use a regular circular saw as a working tool, securing it to the frame.

Opening the bed , it’s quite simple to do, install two channels - paws, connecting them in pairs. Weld the base of the pendulum to them.

Often, a solid metal plate 12 mm thick is used as the base; in this case, the hole for the saw blade is simply cut or drilled.

Need a drilling machine.

After this, it is necessary to make cages for bearings for the pendulum; for this, it is best to contact a turning shop. After turning, welding will also be required .

Also, while creating the rotary machine and pendulum parts, you will need a milling machine and a drilling machine.

Don’t forget about the casings; for their manufacture it is best to use sheet metal with a thickness of 0.8–1 mm. Cutting is done according to ready-made patterns, after which it is tacked by spot welding.

It is worth calculating in advance all the necessary operations and metal consumption.

During processing and workpieces the following were used:

Gas cutter, cutting base metal, pendulum and frame blanks.
Screw-cutting lathe for turning fingers and clips.
Milling machine for processing the edges of workpieces and milling part of the pendulum parts.
Drilling machine.
Welding transformer.

In general, it turns out that the cost of independently manufacturing a frame for a pendulum saw is high; the efforts of an entire mechanical repair shop will be required. In some cases it's worth it, sometimes not. The price is too high.

Sometimes it is easier and more efficient to buy a ready-made tool. This will save time and money.

Cutting tool

As a cutting tool, the saw uses circular saws, abrasive wheels of various diameters and seats.

In this case, you need to look at the saw’s operating manual; the recommended blade parameters are indicated there.

Thus, the Makita LC1230 saw uses a disk with a diameter of 12, with an inch fit, 25.4 mm and a number of teeth of 60 for cutting. This could be a Makita saw blade, 305x25.4x60, for example, Makita B-29393.

Discs from other manufacturers that meet the technical specifications can also be used. Cutting is usually done with carbide-tipped discs at the ends of the disc teeth.

Exploitation

Before use, the machine must be installed on a raised table or workbench, this is necessary for the comfort of its use. It is also necessary to make room for cutting, carrying material and storing workpieces.

The Makita LC1230 saw is compact; its installation requires a small area, but do not forget about moving the material and workpieces; as a result, the working area of the cutting saw is a rectangle of 2x4 meters. With a material length of 2–3 meters.

Cutting with a pendulum saw is not a difficult task, but nevertheless requires attentiveness and accuracy.

Thus, sparks and hot metal particles flying from under the saw pose a particular danger. Partially, the collar installed on the saw body saves you from them.

But nevertheless, we should not forget about personal protective equipment.

Pendulum saw for metal

Pendulum saws for metal and wood

A pendulum saw is a power tool for doing wood and metal work with your own hands.

The device provides fast and accurate cutting of workpieces. Many people believe that a pendulum saw and a reciprocating saw are identical units.

In fact, there are certain differences between them.

The saw performs reciprocating movements during operation. The saber works exactly the same way.

A cutting pendulum electric saw is a fairly compact machine in size, where the cutting tool is a disk and is mounted vertically on a special pendulum.

The size of the device may vary depending on the model and power. The pendulum provides the ability to raise and lower the cutting blade when working on metal or wood.

The assortment is extensive, which allows the buyer to choose such popular saws as Makita, Zubr, PM 400, etc.

Device Features

Drawing of a typical saw device

Circular and pendulum saws have approximately the same principle of operation;
The main difference between the devices is that with a disk cutting tool and the motor are fixed motionless, while with a pendulum device they rise and fall due to the pendulum;
The cutting pendulum installation provides a high-precision cut at a right angle;
Additionally, tools such as PM 400, PM 55, Interskol, Zubr, Makita, KD 300, PM 70 and other representatives of the pendulum saw segment are capable of cutting at an angle;
Often, a cutting system for cutting wood or metal includes an abrasive disc;
The use of appropriate disks allows you to work efficiently. To process a particular product, you simply need to replace the blade;
The blade can also be universal, allowing you to cut all kinds of workpieces with one disc;
A modern cutting pendulum electric saw for cutting workpieces is distinguished by the fact that the cutting blade and disk can be replaced in the shortest possible time. This is what distinguishes the leaders of the segment in the person of PM 70, PM 55, KD 300, Zubr, Makita, Interskol, PM 400, etc.;
Each cutting tool must be equipped with protection systems. This is because the rotating cutting blade is potentially dangerous;
By choosing the desired size of the device, you can cut workpieces at home;
Manufacturers offer both household and industrial models.

Reciprocating saw

In home workshops, grinders, circular saws, pendulum saws, and reciprocating saws are widely used. They all have their own design and technical features.

So that you don’t have any problems finding the differences between a pendulum and a reciprocating saw, let’s clarify some things.

A home reciprocating saw is great for the job;
Like a pendulum saw, a reciprocating saw can be equipped with special blades for wood or metal, or with universal cutting tools;
The reciprocating electric saw is distinguished by its reciprocating movements;
The device is compact in size and can be conveniently used in a home workshop;
A reciprocating electric saw is an excellent alternative to a hand saw, which has certain limitations and difficulty in operation;
The main disadvantage that a reciprocating saw has is vibration during operation. Particularly noticeable vibrations occur when working on thick wood or metal.

DIY pendulum machine

When there are various devices on the market and a completely reasonable question arises about the relevance of homemade saws.

A homemade saw usually has a small structure and shaft, and uses a compact attachment assembled with your own hands. You can make the device from a grinder, an electric drill, or just an electric motor.

Some manage to create a worthy alternative to Makita and Zubr saws. Wood and metal cutting on homemade devices is often superior to factory models. To achieve what you want, you will need to select drawings, take a motor from an angle grinder, electric drill or other device, watch a video and photo of a manual for assembling the unit.

First you need to take an electric motor. The first homemade installation may well be an attachment to an electric drill. Experts advise using an electric motor from a grinder for cutting in a home workshop for a pendulum saw.
From the angle grinder engine, rotation can be transmitted to the spindle using belt drives. A homemade design based on a V-belt is perfect for these purposes.
If an attachment to an electric drill is not your option, then build a frame from metal to fix the future pendulum device. Square metal is used.
On one side, the spindle housing is welded to the metal frame, and on the other there will be a platform for installing the grinder engine. Don't forget about the shaft size. Correctly choosing the shaft size is extremely important for the device to turn out correctly. Typically, the shaft size is indicated in the drawings, on the basis of which homemade pendulum saws are assembled.
Be sure to make a groove in the frame necessary for the passage of the saw's rolling axis. For these purposes, again using a grinder, cut a piece of pipe.
When welding the frame, make sure that the rolling axis, the grinder motor and the spindle are parallel.
Consider the issue of a protective casing, which is usually made of sheet metal. A drive handle is installed on the belt casing.

How it works

To cut materials, you need to know exactly how a pendulum-type electric saw functions.

A pendulum saw can safely be called a circular saw. Here the circular machine is installed on a special frame;
The machine operates from the mains;
Factory models can be equipped with special turntables, due to which the device is used as a miter box. This function cannot be called necessary, but sometimes its relevance is in demand;
The electric cutting saw received its name due to the fact that the cutting blade is lowered by hand along a pendulum path onto the workpiece, and when the cutting is finished, it rises to its original position;
Depending on what blade is used, the size and power of the device, a factory-made or home-made electric saw can cut metal, wood, tiles, porcelain, plastic, glass, etc.;
Cutting discs are used to cut metal. They can be borrowed from an angle grinder;
If it is wood, a circular blade is used.
