Make from a chain saw. Do-it-yourself sawmill from an electric saw. Overview of possible malfunctions of electric saws

The desire to improve an existing tool comes for a reason. The main goal of this experiment is to save money. And really, why buy several tools if you can use different nozzles and make a multifunctional tool.

The grinder is known to every economic homeowner, because with its help it is possible to cut metal, and stone, and grind the surface. But you can’t cut trees with such a device, difficulties arise due to the small diameter of the disk. So the craftsmen come up with various nozzles that greatly facilitate the work in the garden.

Why resort to a homemade version?

Often, it is home-made options for tools or improving existing ones that are done because of the desire to save money. Using improvised means and parts that are left over from equipment or equipment that has become unusable, craftsmen skillfully make various devices, such as, for example, a grinder chainsaw chainsaw.

The second reason can be considered the desire to have a multifunctional tool that will help facilitate numerous tasks on the farm. The indisputable advantage of such a home-made apparatus is space saving. After all, an additional nozzle takes up much less space in a barn or garage than a full-fledged device.

For alteration, you can use absolutely any brand of grinder. The only point worth paying attention to is that factory nozzles can only fit a limited number of models, so when buying, be sure to check if your angle grinder is suitable for the selected nozzle.

Factory nozzles

Now on sale there are special attachments for the angle grinder in addition to discs. Included with the grinder is a device with which in a short time it can be turned into a chain saw. Supplied in two separate boxes containing grinders and a chain saw.

Nozzle set

The estimated cost of such a set is $83.

Electric saw from grinder

Anyone who has ever worked with wood should have a saw in their arsenal of tools, with which it is much easier to carry out sawing work. Below is a diagram of the conversion of an electric saw, which can be made from a grinder

In order to convert the angle grinder into an electric saw, you must have with you:

• Apparatus for welding;
• Adapter for cutters;
• Small thickness metal roller;
• Reducer;
• Saw part.

The first thing to do is to weld a movable wheel at the end of the boom. It is very important to make sure that this wheel and contour are the same contour. If this nuance is not taken into account, then the chain will fall off or be strongly stretched. After that, an adapter for cutters is attached to the wheel. The adapter should not be fixed permanently, it should be removable, otherwise difficulties may arise during operation.

A simple and reliable rework option is the following method. We take a tire from an old chainsaw, an asterisk and a chain. Two perforated corners are twisted together. In one, cut a hole for the nut. We will attach an asterisk to it, and so that it is possible to attach a corner on the casing.

Attach the tire to the remaining corner. After that, we fasten the asterisk and connect the chain. That's all the manipulations, as a result of which we get an effective saw.

The main advice that should not be neglected is the observance of safety precautions when working with such tools. A chainsaw or chainsaw in a homemade interpretation can be dangerous and traumatic. If you decide to take such a step, then follow all the recommendations, drawings and diagrams that are indicated in the instructions for the adapter.

When working at home, you should always be able to make a tool with your own hands. A home-made circular will perform its duties no worse than its factory counterpart, and its maintenance and dismantling will be much easier. In special cases, a circular saw can be converted into a radial or grinder, which has its own very pleasant moments.

You can make a circular saw yourself, for this you need to have good drawings and tools.

Working with a saw and a grinder

Tools and materials:

• grinder 150-180 mm;
• drill;
• self-tapping screws;
• steel clamps;
• sheet steel;
• pliers.

Before you make a circular yourself, you need to try to make it from other tools. Most often, the process is organized with the help of a grinder, because. it can be redone much faster and easier than any other analogues.

The simplest option spoils the tool best. For it, it will be necessary to fasten the tool to the base using self-tapping screws for metal. If desired, you can make through holes with a drill and tighten them with bolts and nuts, which will be much more reliable in operation, because. the tool will no longer strip the thread in case of strong tension. The only nuance that should be taken into account is the factory imbalance of the tool, due to which it will be necessary to fix it in the most careful way, so that there is not even a small chance of movement.

If desired, you can complicate this design, moreover, this will save the tool from unnecessary interventions inside. For fastening, steel clamps are required, with which the tool is wrapped around at 3-4 points, and then fixed to the bolts from 2 sides. This design is very reliable, but special attention should be paid to the quality of fixation in order to avoid even small misunderstandings.

For those cases when the tool is made stationary, you can use more powerful options for angle grinders. The angle grinder itself is attached to the reduction gear with bolts or self-tapping screws (depending on the ability to make a joint without damaging the tool, because sometimes the attachment points do not match), after which they are installed together on the countertop and screwed in the highest quality way.

The most reliable method will be at the same time the most difficult, because the support of a milling turner will be required. His task is only to carve a special part that would be suitable in its parameters for hitching an angle grinder and a countertop. This hitch method is the most reliable, besides, even microscopic movements are excluded, which is far from being achieved in every factory tool.

It should be taken into account the fact that in any case the protective cover is removed, and instead a homemade one is made from sheet steel. It will no longer be possible to use the casing mount due to the fact that it is used for coupling, and the homemade product should be mounted directly to the countertop. For its manufacture, it is necessary to cut a semicircle from sheet steel, at which the tip is bent and clamped with pliers. This design will withstand any surprises after it can be screwed.

When choosing an angle grinder, you need to be extremely careful so that the number of revolutions is small and the power is high. If the speed exceeds 4500 rpm, you will have to use reduction gears, because. otherwise, the cutters will grind very quickly.

It is very important to remember that in no case should a circular made from a grinder be remade back, because. for this reason, every day in all parts of the world, people end up in hospitals with injuries of varying severity. Even if the grinder is urgently needed, and there is no other option, then it is better to be patient, because with a high probability even factory protection will not save.

Saw rework

Tools and materials:

Scheme of a carriage for a circular saw.

• chain Saw;
• steel flat roller;
• nozzle for cutters;
• reduction gear;
• welding machine.

Electric saws and chainsaws are a gift from the 20th century, which fits into life very harmoniously, but there are situations when it is desirable to remake them, which is not easy enough. It should be noted in advance that this alteration is of a momentary nature, but if desired, you can repeat it over and over again without any damage (replacement will take some time).

In order to get a circular, you only need to weld a movable wheel at the very end of the boom, and cut off the end itself. The wheel should ideally follow the contour of the cut off element so that the chain does not stretch or fall off when moving.

An adapter for cutters is attached to the side of the wheel. This adapter is removable so that there are no difficulties when sawing with a chain.

With high-quality refinement, the wheel will not harm the working qualities of the chainsaw in the absence of milling cutters at that moment. In addition, the basic operating speed completely allows you to do without serious third-party modifications.

Using an electric motor

Tools and materials:

• asynchronous motor;
• sheet steel;
• wires;
• reduction gear;
• bolts with nuts;
• adapter for cutters;
• pliers.

There are many electric motors, with commutator, synchronous and asynchronous motors being the most popular. For this activity, the asynchronous option is suitable, because. it has the highest power ratings, low revs and a huge margin of endurance.

It will be very simple to make a circular out of it, so everything can be done in stages:

1. An engine of 4000-4500 rpm is selected, with a power of 2-3 kW and powered by a 220 V socket. If an engine with such parameters was not found, then you will have to use a gearbox that will bring the number of revolutions to the required one. The connection is made using bolts with nuts, but it is advisable not to resort to self-tapping screws, because they can cause significant harm.
2. Now you should choose which nozzle will be: chains or cutters. The cutters grind quickly, but give a thinner cut, which results in greater accuracy. Chains grind much more slowly, but when working they have several times more sawdust. Most often, milling cutters are preferred, because the base price of wood with them comes out a little cheaper, and the quality of the cut is higher.
3. An adapter for cutters is attached to the motor shaft. If a gearbox was used, then you need to mount it on the gearbox. In this case, the joint is made without welding, so that, if necessary, it is possible to replace the nozzle with any digestible one.

At the very end, a protective casing is made of sheet steel according to the method described above. The casing is attached to the gearbox or motor so that there are no complications.

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.

The sawmill disk "Taiga DP-1" easily processes wood with a diameter of no more than 90 cm and a length of up to 7 m. It is capable of producing several types of wood products, equipped with an electric motor with a power of 11 kW. It produces up to 10 cubic meters of wood in an 8-hour shift. Band sawmill "Wood-Mizer LT-15" processes a tree with a diameter of up to 70 cm, the length of logs is not limited, and the weight can reach 2 tons. It is presented in two trim levels - with an electric motor with a power of 11 kW and a gasoline engine with a power of 18 hp.

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.

When working at home, you always need to be able to make a tool with your own hands. A home-made circular will do its duties no worse than an industrial counterpart, while its service and dismantling will be much easier. In special cases, a circular saw can be converted into a radial or grinder, which has its own very pleasant moments.

A circular saw can be made independently, for this you need to have excellent drawings and tools.

For those cases when the tool is made stationary, you can use more massive variations of the angle grinder. The angle grinder itself is attached to the reduction gear with bolts or screws (it depends on the ability to make a joint without damaging the tool, because from time to time the attachment points do not match), after which they are installed together on the countertop and screwed in the highest quality way.

The most reliable method will immediately be the most difficult, because the support of a milling turner will be needed.

It will no longer be possible to use the mount for the casing due to the fact that it is used for coupling, and the homemade product should be mounted directly to the countertop. The question of how to make a circular yourself, sooner or later confronts everyone who works with wood at home. For its production, it is necessary to cut a semicircle from sheet steel, at which the tip is bent and clamped with pliers. This design will withstand any surprises after it turns out to be screwed.

When choosing an angle grinder, you need to be as careful as possible so that the number of revolutions is small and the power is the highest. If the speed exceeds 4500 rpm, you will have to use reduction gears, because. otherwise, the cutters will grind very quickly.

It is very important to keep in mind that under no circumstances should a circular made from a grinder be redone backwards, because. for this reason, once a day in all parts of the world, people end up in polyclinics with injuries of varying severity. Even if the grinder is urgently needed, and there is no other option, then it is better to be patient, because with a high probability even factory protection will not help out.

Electric saws and chainsaws are a gift from the 20th century that fit very harmoniously into life, but there are situations when it is better to recycle them, which is not easy at all. It should be borne in mind in advance that this alteration is of a momentary nature, but if desired, you can repeat it over and over again without any harm (the replacement will take some time).

In order for the circular to come out, it is only necessary to weld a movable wheel at the very end of the boom, and cut off the end itself. The wheel must completely follow the contour of the cut off element so that the chain does not stretch and does not fall off during movement.

On the side, an adapter for cutters is attached to the wheel. This adapter is removable so that when sawing with a chain there are no difficulties.

During installation, it is necessary to look closely at the direction of rotation of the cutter, because. the upper share should always be oriented away from the worker, the lower one - towards the feet. A lot has been said at the moment about how to make an electric saw from a grinder. We will touch on the most common method, for which you must have such initial ones. How to make a boat motor out of a chainsaw, we will focus on how to make a prefix with a propeller, t.alex69 will help us with this. If you do it differently, then even the best goggles will not help out during work, but with the right approach, nothing will prevent brushing your legs with a brush. For rework, 3-tooth cutters are usually used.

Often bending sheet steel for any reason does not work (time, laziness, lack of necessary training or pliers), so you can use an iron corner. 35 cm of the corner is cut off, after that it is welded to the working surface in such a way that the cutter at break does not have the ability to touch the master. But here it is necessary to observe a clear calculation, which will allow avoiding contact between the protective structure and the processed tree species.

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 contact 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.
