Hand chain saw with your own hands. Making a sawmill from an electric saw with your own hands. Homemade sawmills from electric saws: design options

Having your own sawmill is a profitable business, as wood is one of the most sought-after building materials. You can acquire such equipment by buying it ready-made or by building it yourself. The choice of option depends entirely on how many cubic meters of wood will be regularly processed. Experts recommend that you first familiarize yourself with the types of saws. The purchase of a finished product will help save time, and the manufactured one will fully meet the requirements of the owner.

Types of frame units

It is recommended to pay attention to the sawmill from the electric saw, in which the frame is the base. Typical factory-made products are expensive and are considered professional equipment with rich features and a high level of performance. The finished tool can pay off after a few months. It is necessary in the presence of a large amount of forest. In other cases, it is advisable to purchase or independently manufacture a sawmill from a small electric saw.

The equipment intended for sawing up of wood is presented in wide assortment. Most of them are too expensive for a typical suburban economy, and the processing volumes are focused on the scale of industrial enterprises and reach several thousand cubic meters per day. Experts distinguish 3 types of such devices:

• disk;
• tape;
• tire.

Circular saws are the most common in the household. Among their disadvantages are the increased volume of waste in comparison with tape counterparts and the high cost of high-quality discs. Band saws are recognized as one of the most profitable options. They are unpretentious to weather conditions and produce a small amount of waste. It is recommended to use them with a tree whose diameter does not exceed 70 mm. The design of the device complicates the process of reproducing it with your own hands.

Tire sawmills are in great demand among amateurs. They are capable of processing large volumes of wood. A do-it-yourself tire sawmill can be made more easily and quickly compared to analogues.

Specifications

Factory-made devices have their own characteristics that affect the price. The electric saw ПЦМ-1Э (380 V) has small dimensions, copes well with the processing of wood with a diameter of no more than 60 cm and a length of no more than 9.5 m. It is equipped with a three-phase electric motor, the power of which reaches 5.5-7.5 kW.

Equipment PTSM-3B (Stihl MS 660) of small size is capable of processing logs with a diameter of up to 60 cm and a length of up to 9 m. In a professional model, the engine power reaches 5.2 kW. The unit copes with the processing of 6 cubic meters of wood during an 8-hour shift.

Self-manufacturing

To make a sawmill with your own hands, you will need to create a plan. The production process is carried out independently if the sawmill will be used irregularly and there are certain materials (metal profiles, engine).

A sawmill made from an electric saw of its own production has more modest performance than its factory counterpart. A homemade device is used for the production of beams and boards. You must first determine:

• the length and diameter of the logs to be processed;
• unit performance;
• motor - gasoline or electric;
• installation location.

As an engine, you can adapt the carriage for a semi-professional chainsaw. Experts say that household chainsaws and electric chain saws will not work, since their motors are not designed to perform such actions (lack of the necessary power).

The bed, base or frame must be sufficiently stable and reliable, since the safety of the master and the quality of the equipment work depend on this. The length of the frame is determined by the length of the wood to be processed. Guides can be made from pipes, angles, U-shaped profiles. The thickness of the metal is selected taking into account the weight of the processed wood. For a carriage with a saw, metal of 3-4 mm is required. It will be able to support the weight of the armature and the engine.

The choice of disc or tire depends on the type of device being manufactured. Their length reaches 40-50 cm. You can reduce the amount of waste if you use chains with a small cut thickness and a special type of tire. The sharpening angle of the chain should be 10°. Experts recommend making a device for attaching round timber in the form of a low stationary unit.

Step-by-step instruction

To make a sawmill for cutting with a disk, you will need to place the carriage at the top of the structure. Guides made from a 50 mm corner should be 5 m long. If the equipment is stationary, then holes will need to be drilled in concrete and in the corner in 15 cm increments. The structure is attached to the floor with dowels.

A device for fixing a log can be made from a channel or a U-shaped profile. The edges must be welded to the corner. Additionally, it is required to make holes for the bolts so that the log is fixed in the profile. The thickness of the processed logs will not exceed 40 cm, therefore 10, 15 and 20 cm are measured from the center of the profile. Holes for the stops will be located at these points. A more secure fixation can be achieved by installing a movable latch with teeth on the first and last profiles. The latch is made of a metal sheet 4 mm thick. The teeth are sawn with a grinder. It is required to make additional holes in the profile and the latch so that the last unit can be easily dismantled and installed back.

The next step involves the manufacture of the carriage. The design must be reliable, considering a three-phase motor with a power of 3 kW. The height of the product should be 1-1.2 m. It is necessary to mark a corner 4 mm thick and 40 mm long. Then you need to cut the elements. The design of the carriage is welded and requires the connection of parts. At the ends of its corners, holes are made for the wheels.

Next is the installation of the engine with the disk. It is desirable that its height can be adjusted, and the device can work in two positions - vertical and horizontal. You can adjust the unit in height using two pipes, which are recommended to be welded to the carriage frame.

At the next stage, you will need 2 channels welded to each other and a sheet of metal 6 mm thick. The channel is attached to the pipes using U-shaped clamps with a diameter of 10 mm. At its ends, you will need to weld pieces of metal with holes for clamps, which must simultaneously sit tightly on the pipe and, if necessary, slide along it. It is desirable to adjust the height using 2 threaded rods. From above, in the profile of the carriage, it is necessary to make holes for the bars.

A nut is welded to the ends of the profile on which the motor is located, into which it is necessary to screw a rod and weld an asterisk from the bicycle. On both sides, 2 threaded rods and asterisks are formed. Between them, 2 large sprockets from the bicycle are installed, which will have to be tightly connected. As they rotate, the motor will rise or fall.

By creating conditions for turning the motor both horizontally and vertically, it is possible to achieve rotation of the disk in 2 positions. The frame is assembled based on the dimensions of the disk and the engine and is welded to the movable profile. It is necessary to attach 2 bearings, make 4 holes in the steel sheet. They are necessary for mounting the electric motor, to which 2 metal rods will need to be welded, focusing on the diameter of the bearings. Then the structure is firmly attached to the frame. On the back side there will be a handle with stops. The protective casing is made of stainless steel and fastened with self-tapping screws to the frame with the motor. A control panel with "Start" and "Stop" buttons is connected to a fixed engine with a disk.

Owning a sawmill is a profitable device, as wood is one of the most sought-after building materials. There are two options to get a sawmill: make it yourself or buy it in a store. Of course, the second option is simpler, but the first has more advantages. First of all, homemade from a chain saw is more cheap product in addition, such a device will fully meet the requirements of the owner.

Below will be presented two options for home-made saws: a tire sawmill from an electric saw and a circular saw from a hand-held circular saw. To make the first one, you will have to make some purchases, as well as stock up on a welding machine, the second option can be made from materials that any owner will probably have in the garage or on the site.

The sawmills that are sold in the store are excellent productive devices with great functionality, designed for large volumes of wood. Such a tool can pay off in 2-3 months, but it is not advisable if it is used exclusively for domestic purposes. In this case, you can do it yourself from a small electric saw.

Currently, there are three types of sawmills on the tool market:

• disk;

• tape;

• tire.

Circular saws are one of the most common in the household. Their disadvantage is the high cost of high-quality discs, as well as a relatively large amount of waste. Band saws are the most economical, they are not afraid of bad weather, they leave little waste, but at the same time they have a complex device, which makes making them at home a very difficult task. The simplest version of an electric sawmill is a tire saw, they differ in an elementary device, and can also process large volumes of wood of any thickness.

Self-made tire saw

In order to make a sawmill on your own, you will need drawings and certain calculations. The manufacturing process is not particularly difficult, the only point is the availability of all the necessary resources. Naturally, a home-made sawmill will be inferior in performance to factory products. However for the manufacture of beams and boards fit perfectly.

For the manufacture of a tire saw, certain materials will be required:

• metal rails;
• metal tubes with different diameters;
• electric motor;
• chainsaw tire;
• drive sprocket (also suitable from a chainsaw).

As an electric motor, you can use any engine, for example, from a semi-professional electric saw, from an old grain grinder, or you can purchase it specially.

If the choice falls on the purchase option, then a three-phase 5.5 kW electric motor is ideal for domestic needs.

Assembly of the cutting part

The cutting part is represented by a tire and an electric motor connected to each other. The whole structure is placed in a metal frame, which is mounted on a vertical solid axis. In other words, the frame in which the saw is enclosed will be able to move vertically inside another frame. This movement will occur due to the guiding axis.

The first step will be frame manufacturing in which the bus will be installed. The frame is in the shape of a rectangle. On one side of the tire, it is attached to a vertical axle that provides rotation.

The sprocket that drives the tire has a central hole. It needs to insert an axle made of a strong alloy, which has high strength. Perfect fit low carbon steel. The axle opposes the horizontal movement of the tire, that is, the tire itself has a horizontal position in space, and the axle is vertical. On both sides, bearings are put on the axle close to the tire - this helps to avoid vertical displacement of the cutting part. After that, bushings are put on top that clamp the bearings.

The upper part of the axis is attached to the metal profile. The opposite part of the profile is welded to the frame in which the electric motor is installed. Thus, the rectangle is formed as follows: the lower part is a tire, on both sides of it is an axle and an electric motor, the upper part is a bar.

This design does not allow the tire to give play during operation.

The electric motor and drive drum are attached on the opposite side of the axis. To attach them to the tire, you will need the remaining parts from the electric saw. The electric motor is mounted on a rigid body. Here, a large vibration should be taken into account, which means that the basis for the engine must be very rigid. From the side of the engine, a metal axle or a rigid profile is welded. It is due to him that the entire cutting structure will move vertically to ensure that the log is cut in the right place.

Transferring the body with the saw to the base

The next step is to transfer the entire structure to the main frame, which has the shape of a parallelepiped. This framework mounted on rollers, which will move along the rails and saw the log. The sides are a welded frame made of thick metal. From above, they are fastened together. In other words, the front view will resemble the letter P mounted on rails.

The distance between the side posts is 1-1.5 meters and is calculated based on the length of the tire: it should be slightly larger. The side racks themselves are so wide that a structure with a cutting base can be installed inside. If this design has a width of 60 cm, then the width of the side faces should be the same. This is done with the expectation that a saw will be installed inside one of the racks. The axis along which it moves is attached above and below inside the side frame.

Thus, vertical movement is provided by the axis. Horizontal movement occurs with the help of rollers that roll along the rails.

Making a circular saw from a hand-held circular saw

For a home craftsman, having a circular saw at home is a matter of vital importance. It is quite possible to make it with your own hands. The easiest option to make a circular saw is to use a handheld circular saw. For the manufacture of the machine, the design of an existing saw does not need to be redone. Enough make a table for her. Obviously, the saw will be fixed under the tabletop, and the disc through a special hole is above it.

To make a table, you will need wooden bars 40 * 40 and plywood. A square base is made with a side length of 80 cm and a height of 40 cm.

A square sheet of plywood is taken as a countertop, it is best to use lacquered or laminated - it provides smoothness and easy sliding. In the central part, a cut is made for the disk. Holes are pre-drilled in the corners for attaching the tabletop to the table.

A circular hand saw is attached to the tabletop from below. The easiest way to do this is with bolts. Hats must be carefully drowned in the surface.

To turn on the saw, you need to fix the power button on it, and insert the power plug into the socket that will be connected to the start button.

For ease of use, you can attach a metal corner on one side, which will serve as longitudinal stop. To move it, you can make cuts at right angles to the disk, and move it by loosening and tightening the bolts that fix this stop.

A circular saw from an electric saw is a simple and inexpensive option for home use. Of course, when installing a tool, the thickness of the tabletop will steal a little from the disc, but in general, this option is quite enough for domestic needs.

A stationary sawmill is an indispensable assistant in everyday life and professional carpentry. It perfectly copes with those tasks where the efforts of a conventional circular or chain saw will not be enough. Among the areas of its application are longitudinal sawing and processing of logs, furniture production, construction, industrial firewood. Even with such a long list of advantages, not everyone can afford this acquisition: its current price hits the pocket hard and puts off the prospect of buying for many years to come. One of the ways to solve this problem is considered to be homemade from a power saw, popular not only among amateurs, but also among professionals. In view of the relevance of this topic, we will consider one of the options for creating a sawmill from an electric saw with our own hands.

Homemade sawmills from electric saws: design options

Among the whole variety of homemade products from electric saws, sawmills are the most popular and common product that craftsmen have been producing for more than a year. Factory analogues of such devices are quite expensive due to their high performance. They are capable of processing thousands of cubic meters of timber per day of operation. When there is neither such a scale of woodworking nor finance, you can pay attention to one of 3 types of home-made sawmills:

• tape; They have a complex design, but are adapted to any working conditions.
• disk; Fairly simple to assemble, but not reliable, which is why they are in demand among amateurs. Circular sawmills based on electric saws are quite common in everyday life, productive and versatile in terms of tasks;
• chain.

In view of this, we will dwell in detail on their manufacturing technology.

Circular sawmill from an electric saw: a detailed description and drawings

Before you make a homemade sawmill from an electric saw, you need to decide on:

• the length of the materials to be processed on this machine;
• workpiece volumes;
• future homemade location.

Special attention should be paid to the choice of the disk blade. Discs with a size of 400-500 mm, which are most often used in modern circulars, are more than suitable for these purposes. And you can solve the problem with sawdust by using a disc with a minimum thickness.

The device of a circular sawmill based on an electric saw

The design of any home-made sawmill based on an electric saw implies the presence of:

• frame element - a supporting part that connects all other parts together;

• motor part - it is advisable to dwell on three-phase modifications of electric saws: household models powered by a 220 V network may be low-power;
• cutting headset - the disc is installed in one of the planes - horizontal or vertical;
• carrier node - for everyday tasks, an ordinary workbench or table will fit, on which the logs will be fed by hand. For more complex designs, they are supplemented with a mobile carriage;
• adjustment mechanism - controls the electrical circuit of the homemade product, starts and turns off the motor. Most often located on the frame.

Assembly sequence

• installation of a frame frame - its dimensions are selected individually, taking into account the diameter of the disk and the dimensions of the motor. 2 bearings are attached to it and 4 holes are drilled for aggregation with an electric motor;
• the plane along which the lumber will be fed. For small-scale work, you can use a ready-made stationary workbench or work surface, which must be installed strictly horizontally. It is very important that its longitudinal axis corresponds to the axis of the frame base;
• movable carriage - its approximate size should reach 1 m. Mobility will be betrayed by the wheels, which will be installed at the end of the corner;
• aggregation of the engine with a disk - it is better to give preference to those sawmill designs where the height of the knife block could be adjusted manually. To do this, two pipes are attached to the carriage, to which a metal channel is welded. Through the metal lining, they are attracted to the pipes with clamps. Raising or lowering will be done by two steel bars. The movable position of the engine will be provided by bicycle sprockets connected to the ends of the profile with the motor, connected to it through a threaded rod.

To improve the results of efforts, homemade products can be strengthened with a second circular knife. As in industrial counterparts, their location must be strictly perpendicular to each other. For sawmills with a power of more than 3 kW, an additional traction device is not required. Otherwise, a second motor is taken and a second drive is created.

Unlike a standard chainsaw, a homemade battery powered saw is noticeably behind in power. However, at the same time, it has other obvious advantages: compact size and mobility - the electric saw can be easily disassembled and put in a backpack. In general, despite the low power, it will still be useful.

To make a homemade electric saw, you will need a piece of sheet metal 3 mm thick, from which you will need to cut the base for the body. You will also need a short bar, fasteners and a piece of saw chain.

Main stages of work

First of all, we cut out the case to which the electric motor will be attached. Then, on a lathe, we grind a steel pulley onto the drive shaft of the engine. To make a homemade cordless electric saw, you will need a small tire and a piece of chain of a suitable length.

Then you need to make a wooden handle, in which you will need to drill a hole and install the power on / off button.

At the next stage, we make a whole 24V battery pack from 18650 batteries. The contact plates are welded using resistance welding. A full charge of the battery will last for one hour of continuous operation of the saw.

From a piece of steel round pipe, it is necessary to make a persistent handle to make it more convenient to saw. Then we proceed to the assembly of the entire structure. The result is a compact electric saw that runs on a rechargeable battery.

The cost of lumber is high enough for most private craftsmen involved in private construction, which forces them to show wonders of ingenuity. Using simple log sawing technologies, you can not only save money, but use all available personal resources efficiently and rationally.

First of all, this concerns wood and equipment, because they lay the foundation for successful work. An excellent alternative to a stationary sawmill is from a power saw, which you can do with your own hands.

What can be made from an electric saw

Since cutting equipment is always needed for sawing logs into bars and boards, rack (band) and circular saws are used in factory sawmills. Naturally, for the construction of a small house or the manufacture of several cubes of boards, it is impractical and expensive to purchase such a machine. The best alternative it can be a home-made design based on a chain saw.

Its potential is quite enough to meet the small needs of private developers, and just ordinary home craftsmen who cannot afford ready-made lumber. The electric saw here is the main device that combines the universal mechanical supply of the cutting tool, the electric drive. A chain sawmill is best, unlike a circular saw, suitable for longitudinal bucking and sawing logs, as it has:

• rough cut, sufficient for effective ejection of sawdust;
• capaciously arranged electromechanical supply of the cutting tool (chain);
• relatively low cost.

How to make a sawmill from a power saw with your own hands

In fact, the cost of all equipment depends on the task. It is important to correctly assess the potential of the existing equipment. Everything is subject to accounting - from the density of wood to the power of the electric motor of the saw itself. However, all these calculations are quite simple. In addition, in almost any forest area there is an opportunity to buy roundwood, which will cost significantly less than lumber.

For creating a homemade sawmill from an electric saw will require:

1. 1. Bed, in the amount of two pieces.
   2. Fasteners both for the saw itself and for fixing the workpiece (log).
   3. Electrical cable with switch and plug socket.

Advice: In most cases, we are dealing with wood that has a low fiber density. These are pine, linden, and similar trees, which will facilitate the selection of a saw based on an electric motor. For efficient work, a saw with a power of more than 1.5 kW is almost always suitable. The only limitation here will be the speed of its work. The stronger the engine, the faster the work and the cleaner the cut.

The listed list should be disclosed in more detail on the example of one design, since it is not possible to describe all their modifications in one article. This is perhaps one relatively cheap, but very popular project. And in terms of cutting quality, it is almost as good as the well-known mobile sawmill Logosol.

bed

There are two of them in the design under consideration: one for the saw, and the other for fixing the workpiece. The principle of operation of this unique chain sawmill is based on the manual supply of an electric saw to the workpiece. It is easy to understand that it must move along a rigid structure, which is commonly called the machine bed. In our case, this is a hard, but necessarily flat edged board in all two planes. To stiffen the guide, you need to frame it with two tin corners. They are easy to buy in the store profiles of metal structures.

It is attached to wooden poles. As such, you can use blanks (wood chocks) or trimming a beam with a cross section of more than 18 cm. The bed itself will stand more stable, and it will also be more convenient to fix a board of maximum width.

A little lower should be placed the second frame - to fix the workpiece. Its height is selected empirically, but it is better to use linings from boards of the exact size. The very design of the frame for the log is located on the same chocks.

Connecting them together is a personal preference, since for work it is enough to dig or screw its racks hard. The distance between two parallel beds can be set arbitrarily. However, given the length of the saw bar, it should not be installed more than 3 cm away. It is better that it stands close to the saw guide and strictly parallel horizontally with respect to it.

Saw fixture and workpiece fixation

To fix the saw on the guide frame, a metal corner is used. A saw is attached to one shelf with bolts. To the other cheek of the corner, which lies on the plane of the guide board, two aluminum corners are additionally fixed, but better than steel corners.

The main corner should be of a wide section, preferably more than 10 by 10 cm. Thus, the saw itself will sit more rigidly, and it is easier to screw the guide corners from the bottom of the second shelf of the square. Guide angles should be fastened with a small gap, taking into account the width of the guide frame. This design makes it easy to remove the saw from the bed. So it will be more convenient for setting up equipment and dismantling at the end of work.

Fix preparation can be done in several ways:

• At the ends of the log with temporarily hammered nails
• Using special pads (saddle curved in a semicircle)

Fixing logs with hardware is a temporary option when you need to cut several logs. However, for permanent and mass sawing, it is desirable to make special fasteners. Saddles that roughly copy the radius of the logs are usually made from stiff steel tape. In extreme cases, parallel bars are used on each rack of the bed.

electrical equipment

It is impossible to call the electrical equipment of a home-made sawmill difficult, since most of it is already in the saw. You will need an electrical wire, a special connector and plug, and a switch. The entire future electrical circuit will look like a universal extension cord, similar to the cord of a floor lamp or sconce.

The presence of a switch will allow you to better control the work of the homemade product, and a special connector for connecting the saw fork is convenient for moving, as it does not get stuck anywhere. So that the power cord does not accidentally jump out during operation, it must be fixed to the saw itself with a bridle or electrical tape. To ensure safe operation, the presence of an overload and short circuit protection machine in the electrical panel will help.

Conclusion

A chain sawmill based on improvised means is no worse than factory equipment. The only thing she loses in is the speed of wood processing. But given the nature and purpose of using homemade equipment, this is not necessary. With only a power saw on hand and some money to assemble an electric extension cord, you will have a great opportunity to have your own sawmill.
