Homemade sawmills from an electric saw: design options
Among all the variety of homemade products from an electric saw, sawmills are the most popular and widespread product that folk craftsmen have been producing for several years. Factory analogs of such devices are quite expensive due to their high performance. They are capable of processing thousands of cubic meters of forest per day.
When there is neither such a scale of woodworking nor finance, you can pay attention to one of 3 types of self-made sawmills:
- tape; They have a complex design, but they are adapted to any working conditions.
- disk; Simple enough to assemble, but not reliable, which is why they are in demand among amateurs. Circular sawmills based on an electric saw are quite common in everyday life, are productive and versatile in terms of the tasks performed;
- chain.
In view of this, let us dwell in detail on their manufacturing technology.
What is different from a jigsaw
The main and most important difference between an electric hacker and a jigsaw is the different purpose of these tools. We can say that the electric hawk is designed to destroy, and its younger relative is to create.
Most often, an electric hawk is used for quick cutting of material, mainly in straight lines. She can easily cope with structures of any shape and any material. Cardboard, wood, gypsum fiber, metal, concrete, glass, ceramics - this is just a small list of materials that can be sawed with an electric chopper. Such a front of work is typical just for dismantling and other, relatively rough, repair work.
The jigsaw is more suitable for more precise work with flat surfaces and it is more expedient to use it in cases where curly cutting is required.
Another major difference is the shape of the tools, on which their capabilities depend. The elongated body of the electric jigsaw and a rather long knife blade allow cutting in the most inaccessible places, where it is simply impossible to crawl with a wide electric jigsaw.
Thanks to its design and flexible blade, the saber saw can cut protruding elements flush with the wall, which a fairly wide jigsaw cannot boast of. With an electric jigsaw, you can easily cut "on the weight", for a jigsaw a flat surface is required to ensure a tight stop in the material with its working area, in order to avoid tool breakage.
Thus, when you need to decide which tool is needed: a saber saw or a jigsaw, first of all, you should clearly identify the intended tasks.
The electric chewer is less whimsical to operating conditions and can work in the most extreme conditions. Even beginners can easily master it. The tool is capable of making fairly straight cuts, but nevertheless is more suitable for rough work.
A jigsaw in the hands of a master becomes an unsurpassed tool for cutting curly elements, but it requires more skill and has limitations in its capabilities.

The attachments, with which you can cut various materials, are also used in order to carry out many operations. Each species has unique properties and design. To cut the rough material, cut-off nozzles are used. This device is in the form of a disc that has a cutting edge. Usually there is a solid cutting part, but there is also a segmented one.
To cut various materials from wood or drywall, saw attachments are used.Their feature is that there are special teeth in the cutting part. They can be of different shapes. The attachment also has a saw blade for smooth cuts on plain and laminated boards. For grinding workpieces with a metal, concrete and wooden base, use a roughing grinder. With the help of such a nozzle, you can easily clean the plane from the old layer of paint. Grinding wheels can also be used to remove the primer.
The strippers consist of a circle. The edges of the circle are made of metal wire. They are often used to remove rust and other contaminants from a metal area. In most cases, these nozzles are needed to prepare the pipes for painting. If you need high precision in work, then you need to use a grinding attachment with a frame. Polishing tips are used to level surfaces. They are most needed after sanding. These attachments have disc categories. The disc can be felt, felt or have emery wheels. Velcro is used to fix them to the device. Thanks to this property, it will be possible to quickly change the attachments.
It is also necessary to mention the grinder attachment for Chinese gasoline saws 45.53 cubic meters. see It will fit the gasoline saws of such Chinese firms as Carver, Forza, Champion, Forward, Breit and others. The attachment is suitable for cutting metal, stone, grinding and sanding surfaces. And you don't need to use electric grinders. Such a nozzle will be necessary when working in places where there is no power supply.
To prepare the attachment for work, you need:
- remove chains and tires;
- remove the sprocket and install the pulley;
- install the belt and secure with the side cover;
- tighten the belt.
The nozzle has technical features:
- grinding and cutting wheels with dimensions from 182 mm;
- fit has a size of 23 or 24 mm;
- clutch cup with a diameter of 69 mm;
- the weight of the nozzle itself is 1.4 kg.
Chainsaw sawing trestles
Working with a chainsaw greatly speeds up the fuel harvesting process. The performance of a chainsaw is significantly higher than that of a conventional saw. But when using a classic trestle, when sawing with a chainsaw, chain clamping often happens. It can be eliminated only by turning the log with a cut down in time. It is difficult and creates additional inconveniences in the work.
For such work, you can make goats according to the drawings for cutting firewood with a chainsaw with your own hands. This device provides a mechanism to prevent the chainsaw from jamming. Convenience and advantage of the device:
- there is no more need to turn the log over;
- chain clamping is completely excluded;
- the sawer has both hands free to control the chainsaw;
- the machine can be held in place with one foot;
- productivity increases dramatically.
If you have the necessary materials and capabilities at hand, then it is worth making such a product with your own hands. The benefits of using it are obvious. Making a goat with your own hands, regardless of the material chosen, will facilitate the cutting process, increase its productivity and save time.
Sawmill from a chainsaw with your own hands: video instructions and drawings
Having the drawings available and having studied the video instructions, it is quite simple to independently make a structure for processing logs, boards and slats. Before starting work, you must choose a suitable place. You can install a sawmill from a chainsaw in an old barn, garage, hangar, or even just under a shed. If the room for the unit will be closed, then you should take care of the exhaust.
Sawmill from a chainsaw - option number 1
For the manufacture of a structure, in addition to a chainsaw, you will need:
- two channels 8 meters long and 140-180 mm high;
- two rails;
- corners 50x100 mm and 40x40 mm;
- pieces of a water pipe 25 cm as screeds;
- a steel plate 4-6 cm thick and 60 cm long;
- movable hoses;
- pipes with a diameter of 35-40 mm.
Making a sawmill with your own hands should begin with assembling the base from the rails and corners of 50x100 mm turned upside down. They should be installed strictly parallel to the floor, so you need to use the building level.
Next, the following work is performed:
- Along the length of the base, according to the drawing, holes are drilled with a step of 1-1.5 meters and a diameter of 14-16 mm.
- Then, according to the number of holes, ties are taken, which are connected with bolts.
- Racks are made of metal squares and the base is placed on them. The distance between the outer posts and the base should be about 100 cm.
- To make the structure more rigid, the braces between the posts can be welded.
After the base is completed and installed, you need to make a movable cart with your own hands. To do this, a 40x40 mm corner is welded from the bottom of the steel plate and the product is placed on rollers or bearings. On top of the plate, two corners are welded to which the chainsaw is attached.
At the last stage of work on the manufacture of a homemade sawmill, it is necessary to make a structure for fixing the logs. To do this, move hoses and pipes must be positioned at the required height and secured.
The first version of a homemade sawmill from a chainsaw is ready. There is another way to make a do-it-yourself wood processing unit. The tools and drawing for it will need the same, however, the design itself is more refined.
Sawmill from a chainsaw with your own hands - option number 2
The structure consists of four main units:
- Saws with a drive.
- A mechanism for adjusting the thickness of the manufactured board.
- A mechanism for moving the saw part of the structure.
- Devices for fixing logs.
Since a chainsaw with a working engine and cutting teeth is already available, it will be necessary to make only both mechanisms and a device for fixing the logs with your own hands.
Mechanism for regulating the thickness of the boards.
Logs are sawn by raising or lowering the base, which must be welded to the plate using four folded nuts. On top of this device, lock nuts must be installed, which must be tightened after the unit has been adjusted to the desired thickness of the material being processed.
Saw movement mechanism.
The saw in the structure moves along the frame along the guide corners, the distance between which should be 50 cm. Two rollers or 20 mm bearings must be welded to the posts. The lower roller should keep the sawmill from lifting, and the upper roller should be supported on the guide angle.
Device for fixing a log.
On such a unit, the logs are fastened using two combs - a fixed one and a moving one by means of a screw. After the material to be processed is set, the moving ridge is fixed with screws in a stationary state. Now you can start boldly operating a homemade sawmill made from a chainsaw.
Safety engineering
A chainsaw is a dangerous tool that requires care and attention. The use of accessories significantly increases the risk, since the cutting tool is not visible during sawing, which lulls the vigilance of the inexperienced worker
It is necessary to ensure complete safety when moving the carriage, install all handles at a sufficient distance from the moving chain. In addition, you must comply with all standard safety requirements when working with a chainsaw:
- work only with a serviceable chainsaw;
- do not refuel while the tool is running;
- refuel the chainsaw with fuel in the open air or in a ventilated area;
- do not smoke while refueling and working;
- carry the chainsaw only after a complete stop in the case;
- start a stalled chainsaw only after removing it from the cut;
- monitor the actions of assistants so as not to accidentally injure them;
- use personal protective equipment - glasses, gloves, headphones.
The requirements are simple, but they allow you to maintain your health and ability to work for yourself and your assistants.
A self-made chainsaw carriage greatly expands the capabilities of the tool. There is an opportunity to produce different types of lumber, the accuracy and accuracy of work increases. However, this also increases the risk of using the tool. All homemade carriages and other devices are a risk group, so people without proper experience and skills are not recommended to start making such devices.
You need to correctly assess your capabilities and level of knowledge, the degree of danger and responsibility of such work. If the user has sufficient training and experience, the process of making the carriage will not take much time and will provide him with a useful and convenient fixture.
Homemade electric saw from a grinder
Some craftsmen decide to convert standard equipment into more, in their opinion, functional.
Diy circular saw from a grinder
To convert the angle grinder into a circular saw, you will need a saw blade, bolt ties, a gearbox, a metal corner, steel rods, metal clamps, a set of tools. Before assembling the device, it is advisable to make drawings, calculate the gear ratio, taking into account the parameters of the toothed disk.
The grinder's engine will become the power plant for the circular saw being created. First, remove the disc from the angle grinder. The new toothed disc is pulled together with a metal corner. The body of the angle grinder itself is fitted with clamps, from the bottom - with a double strong metal tape.
Next, a hole is made in the gearbox for installing the handle attachment and grooves for the bolts are drilled in four places. The metal rods are shaped into loops of 6 cm each, then the handle is attached to the body along with the electric motor. Sometimes such a saw is installed on a plywood or chipboard base to create a stationary circular.
How to make a circular saw from a 2.4 kW grinder, you can watch the video:

Chain saw from a grinder
For homemade products, you will need a saw headset (chain + tire), an asterisk, a set of bolts, a metal profile, and tools. First, remove the disc from the grinder, screw the prepared bracket onto the shield. Install the sprocket on the motor shaft. The rail is then positioned behind the bracket ties. Install the chain and adjust its tension.
The video report presents a step-by-step diagram of the work of creating an electric saw from a grinder.

2> Why do they use the homemade option?
Often, it is homemade options for tools or the improvement of existing ones that are done out of a desire to save money. Using improvised tools and parts that remained from equipment or machinery that have become unusable, craftsmen masterfully make various devices, such as, for example, a chain saw from a grinder.
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 homemade device is space saving. After all, an additional nozzle takes up much less space in a shed or garage than a full-fledged device.
For alteration, you can use absolutely any brand of grinder
The only thing worth paying attention to is that factory attachments can only fit a limited number of models, so when buying, be sure to check if your grinder is suitable for the selected attachment.
DIY chainsaw brush cutter - Magazine "Himself an inventor"
For complete maintenance of hedges in the garden. Or a simple treatment and trimming of bushes.It is not at all necessary to purchase a specialized brush cutter. It is quite possible to make it yourself with the help of improvised means and an ordinary chainsaw.
Many components can be found in ordinary garage rubbish, so to speak, an economic person. And some can be purchased at your local hardware store.
Necessary materials:
- Gasoline saw.
- Steel strip 150 cm.
- Bolts, washers, nuts.
- Enamel in a spray can.
- Sandpaper.
- Solvent.
- Electrodes.
You will also need the following tools:
- Circular saw (grinder).
- Drill or screwdriver.
- Welding machine.
- Vise.
- Roulette.
- Spanners.
- Emery stone.
Homemade brush cutter manufacturing technology
The task itself is to create a kind of chainsaw attachment. When using which, the branches will not bounce off the saw blade, but, on the contrary, will linger and fit snugly against it.
Outwardly, the end result of the nozzle should resemble a certain longitudinally elongated letter "F".
So, taking a tape measure, you need to measure and mark on the steel strip a section of 60 cm and three sections of 30 cm each.
Then take a circular saw, after fixing the metal strip in a vice, you need to saw it in the marked places. Thus, having received four segments, three of 30 cm and one 60 cm long.
Putting a strip 60 cm long horizontally, vertically apply to it at an equal distance a strip 30 cm long. Thus, forming some kind of teeth.
Turning on the welding machine, we weld the strips of the resulting structure together.
Then, on the main strip of the structure, the length of which is 60 cm. Two holes must be drilled at a distance of 20 cm from each edge. With the help of these holes, the attachment itself will be attached to the chainsaw blade. Similar holes should also be drilled in the saw blade, equal to the distances of the holes in the nozzle.
In principle, everything is ready. It remains only to process the edges of the resulting comb on an emery stone, to give the ends of the strips a rounded look. So the future brushcutter will be safer to use.
Important: when performing all work on the creation and assembly of the brush cutter. And also in its further operation, it is necessary to use protective goggles to avoid injury.
Before installing and bolting the accessory to the blade. It needs to be cleaned with sandpaper, degreased with solvent and covered with enamel from a spray can. This will not only give an outwardly pleasant aesthetic appearance, but also protect it from corrosion.
Having completed all these simple operations, we attach the resulting structure to the chainsaw blade with the help of bots and nuts, using wrenches.
And now the homemade brush cutter is ready to go. It remains only to fill the saw with gasoline and start it. With this simple design, you can handle any bush.
Features of the sawmill
Usually, wild logs are used for sawing with a sawmill. They have an irregular shape and uneven structure. Therefore, they are fixed in a static position, and the sawing is carried out by a carriage with a sawing tool. Otherwise, it will be very difficult to ensure an even cut. The exception is large industrial sawmills, where the saw is stationary and the logs are fed to the cutting element by a hydraulic press.
Important! A long log is always cut longitudinally from the bottom of the trunk to its top. Otherwise, any saw will get stuck or break. In general, a wood sawing machine consists of the following parts:
In general, a wood sawing machine consists of the following parts:
- The cutting element is a saw.
- Motor that drives the cutting parts.
- Carriage for feeding the saw to the wood.
- Carriage guides.
- A carriage for fixing wood and a log feed unit.
- A frame that holds all parts together into a single structure.
Depending on the design features, some parts can be combined with each other. So, for example, a chainsaw, often used in homemade sawmills, combines the cutting part and the drive.
For large industrial logging sites, complex structures are used with specially designed fixtures and saws for this purpose. In the household, there is no need for such tricks. As a rule, materials at hand are used that can cut an average log into bars.
Next, we will consider what improvised devices you can use to make a sawmill at home with your own hands.
Sawmill from a chainsaw
This type of design is the easiest to manufacture, but it also requires special skills, tools and experience with them.
This type implies the installation of the carriage on the rails, but is not required. As guides, you can use a flat wooden strip, on which the carriage structure will easily slide. It allows you to remove the first layer evenly. The plane of the saw cut on the log is used as subsequent guides.
Attention! The absence of a bed and carriage adds a number of complications. The master may have problems holding the log in one position.
You must not start work without proper fixing, as this can lead to injuries.
The step-by-step process for making a carriage for a chainsaw will look like this:
- Making the base. To do this, we weld together a pipe with dimensions of 25x25 mm.
- Perpendicular tubes are welded to the base on opposite sides, the size of which is 30x30 mm. They are necessary for fixing the movable part that holds the saw and sets the thickness of the sawed bars.
- Nuts are welded into the side parts of the guides. With their help, it will be possible to fix the moving parts at the desired height with bolts.
- We make the moving part. It consists of two tubes with a T-shaped end. The end of the pipes is made in the form of a vise, clamped with bolts and nuts. These clamps will hold the saw blade. The size of the pipes is 25x25 mm.
- To prevent the saw chain from rubbing against metal parts, two metal plates of the required dimensions are welded onto the inner parts of the vice. They completely depend on the thickness and width of the chainsaw blade.
- We assemble the carriage into a single structure, select the desired height and install the saw. The sawmill is ready to use.
The video below fully describes the carriage manufacturing process. In addition, the author of this device notes the main difficulties and some inaccuracies made by him during the assembly of the sawmill. This will allow you to avoid such oversights and make the log sawing device more practical.
The bottom line! This carriage design is suitable for personal use and one-time sawing of wood. It will not work for commercial purposes.
Trestles for cutting firewood with chain saws
But nevertheless, when we deal with large volumes of logging, then torturing ourselves with manual sawing of logs is a wasteful occupation, in terms of time and physical costs. Gasoline and electric chain saws speed up the process tenfold and reduce physical labor.
But traditional trestles are not suitable for working with them, due to the high risk of injury and tool breakage when clamping the saw bar in the cut. Of course, you can only saw logs that are beyond the dimensions of the goat, but at the same time you cannot achieve rational cutting of the logs. Therefore, for working with such saws, other devices were invented, which, by tradition, retained their old name, although they bear little resemblance to their grandfathers.
The simplest goats for working with a chainsaw have a similar design.
Heavy, stable base and a pair of arms for securing the log. What else is needed? Sawing takes place outside the dimensions of the structure, and the log is held in it by the foot.The productivity of the work is low, but such goats are quite functional.
For cutting not thick logs, the most suitable, in our opinion, will be goats of a similar design:
Their only drawback is not sawn logs of the lower row, but for large volumes this design drawback will not be fundamental. And you choose the dimensions of such goats depending on the same length of the firebox of your stove, the length of the bar and the power of your saw. Their undoubted advantage is their quick disassembly, which makes it possible to simplify and speed up the removal of lumber.
A similar design of a goat, but with the ability to finish off bundles of logs to the end, due to the presence of transverse supports that provide a gap between the woodpile and the base of the goat, is shown in this video, but the lack of the ability to quickly disassemble to a certain extent neutralizes this advantage.
Although it is possible to turn on the front side, however, with a little more effort.
For thicker logs, a similar design will work, but with them fixed in the sawing container, which will prevent the logs from gripping the saw.
And the size of the chocks obtained in such goats can be minimal.
Not the most successful, as it seems to us, but a completely workable version of the device for sawing not very thick logs is shown in this photo:
The most valuable thing in this design of a goat is a template-stop, which allows you to maintain the ideal height of the chocks, which is extremely important for small-sized ovens
Do-it-yourself goat for cutting firewood
The foldable firewood goat is a convenient and compact stand. It allows easy sawing of logs and thick boards. The foldable stand does not take up much space and can be stored in a shed or garage. For the manufacture of the structure, you will need to prepare a high-quality timber and board. Assembling the stand takes about 2 hours.
Necessary materials
It is not difficult to assemble a wooden goat for cutting firewood with your own hands. But it is recommended to use durable materials in the work. To maximize the life of the structure, you should pre-treat the tree with an antiseptic. This will protect the materials from moisture and prevent damage from harmful insects.
A wooden trestle for sawing firewood is made with the parameters 1 × 1 m. This size of the product is sufficient for sawing both large logs and small stumps. Before starting work, the contractor will need to prepare the following materials and auxiliary products:
- timber: 6 units with a length of 1 meter;
- board: 4 units with a length of 1 meter and a width of about 7-8 cm;
- M8 bolts: 3 pieces;
- nuts and washers: 3 each;
- wood screws: 24 pieces.
From these materials and consumables, you can assemble a compact folding goat, which will have increased stability. Additionally, for work, you will need a screwdriver, a saw on wood.
Step-by-step instructions for making saw girders
Further, between them it is necessary to install an M8 bolt with a semicircular head.
It is necessary to connect the first pair of legs, tighten the bolt, install the washer and nut.
Repeat the procedure for two more support pairs. Further work is carried out according to the following scheme:
2. On a pair of planks located on one side of the goat, drill two vertical holes at a distance of 67 mm from each edge (see the drawing of the goat). Additionally, holes are drilled on one side at a distance of 245 mm.
3. On the second pair of boards, the following pairs of vertical holes must be prepared: at a distance of 22 mm from the edge on both sides, at a distance of 335 mm from one edge.
4. Prepared boards, pre-broken in pairs, are screwed to the legs: the lower ones at a distance of 80 mm from the edge, the upper ones at a distance of 535 mm from the edge (see the diagram of a wooden goat). The indicated indents are measured to the lowermost line of the board.
Features of storage and operation of goats
Carrying out work according to the specified instructions, it is recommended to additionally use the attached drawings, photo and video materials. They will help you to easily make durable saw girders.
The finished structure is capable of supporting a lot of weight, but it is important to store it in normal conditions: a dry room. Continuous exposure to moisture or humid air will degrade materials
It is especially important to consider the rules for using the workpiece. It is not recommended to overload it with heavy logs.
Foldable trestles are suitable for cutting firewood with a chainsaw and a hand saw. A reliable design will be indispensable in a summer cottage or in a private house. With its help, you can easily and quickly harvest firewood, logs for kindling a stove, barbecue or a home fireplace.
Video of making a goat for cutting firewood with your own hands
Another way to create a homemade sawmill
You can use another method of making a sawmill. In terms of technology, this option will not differ much from the previous one. The tools and drawings will be identical as in the first version.
The main components are marked on the drawing. First of all, this is a chainsaw, its drive and a mechanism with which it will be possible to adjust the thickness of the resulting board. It should also be noted a mechanism that allows you to move the cutting part of the structure, and a device for reliable fixation of the log.
The process of sawing a log on a sawmill is carried out by lowering or raising the base of the device, which is held by four screws or welded to the plate with nuts with bent edges. A locknut is placed at the top of the base and tightened once the sawmill is fully set up. Adjustment is made to the desired thickness of the processed log.
The cutting part moves along the corners, which serve as guides along the frame. Between these elements, a gap of 50−55 cm is observed. Two rollers are attached to each rack, of which the upper one rests against the guide corner, and the lower one will keep the sawmill from lifting. Instead of rollers, 20 mm bearings can be used.
The wood on this structure is fastened with two combs, one of them moves with a screw, the other remains motionless. After installing the log, the first movable element is fixed in a stationary state with several screws. After installing the fixing device, you can start working on the sawmill.
Rules for working with metal
Working with metal
In order for the blade to be strong and resilient, in the process of its manufacture it is necessary to follow the rules for working with metal. They are as follows:
- The workpieces must not have visible and hidden damage. Before making a knife, the workpieces must be inspected and tapped. An integral part sounds loud, and a defective part sounds hollow.
- When designing the shape of the blade, angles must be avoided. In such places, the steel can break. All transitions should be smooth, without kinks. The cuts of the butt, handle and guard must be ground off at right angles.
- When sawing and sharpening, do not overheat the steel. This leads to a decrease in its strength. An overheated blade becomes brittle or soft. During processing, the workpiece must be constantly cooled by completely immersing it in a bucket of cold water.
- When making a knife from a saw blade, you need to remember that this product has already gone through a hardening cycle. Factory saws are adapted to work with the hardest alloys. If you do not overheat the fabric during the grinding and finishing process, then you will not have to harden it.
The blade shank must not be made too thin. It is on this part of the product that the greatest load will fall.
Chainsaw hedge trimmer with your own hands!
When we laid a spruce hedge, we thought that we could cope with its formation with simple garden shears.
Today it is higher than the fence, although we have been cutting our hair for four years.
At the expense of gardening equipment: we noticed a trend that does not make us happy. The number of instruments is growing. They all take up space and require maintenance. I would like to get more opportunities without increasing the amount of equipment.
We have a STIHL MS-180 chainsaw. I tried to cut the trees for her, but the branches slide off and it turns out crooked. The "comb" will solve the problem.
For the base, you need a 40X4mm strip.
We cut off 300mm and process the surfaces.
We cut 8 strips of size 130X20 mm from 2 mm metal.
We weld them to the base and process the seams.
For fixing the chainsaw in the tire, holes must be drilled.
We check the gap between the teeth of the chain and the "combs".
Anyone who is interested in the process of creating a hedge from ordinary spruce, ask, we will definitely share.
Thank you for the attention! We are waiting for comments
An option for the manufacture of the simplest sawmill based on a chainsaw
The first version of a homemade sawmill is quite simple, so everyone can implement it, spending no more than a couple of hours of time on it. To implement this method, you don't even need a welding machine, so let's get down to action. Initially, we prepare the necessary materials:
- Hollow steel beams measuring 5x5 cm and 1 meter long. The number of such bars is 6 meters (it all depends on the length of the tool bar)
- Connecting elements in the form of fastening bolts with a diameter of 8-10 mm in the amount of 10 pieces
When all the components for the manufacture of the device are ready, you can proceed.
- Initially, you need to make a lattice base from steel bars
- Base size is equal to the length of the tool bar
- This base is a guide when sawing logs
- To fix the tool and adjust it, two bars are fixed perpendicular to the base
- At the ends of the beams, which are attached to the base, you need to make clamps to secure the chainsaw bar with lugs through which the chain will move freely
As a result, we get a device of the following type, as shown in the photo below.
Specifically for the manufacture of this sawmill, a welding machine was used, due to which the costs of connecting elements were reduced. However, it can be done without welding, but using a drill. Which is better, you can decide for yourself, but in the end we get an expansion of the functionality of a useful tool in the household - a chainsaw. How this type of sawing equipment is made is described in detail in the video.
Mowing shield and handle
In a homemade lawnmower, the mower shield not only covers the knife, but also serves as a supporting frame.
In this capacity, you can use a large frying pan, a bowl, the bottom cut from a large saucepan or boiled out.
A convenient grip is a bicycle handlebar attached to a tube of suitable length.
The diameter of the latter is 3 cm. A steel or plastic water pipe, a handle from the same stroller, and even a handle from some agricultural tool will do. For a person with an average height, the handle is positioned at a height of 90 cm.
Without fail, this element must have an emergency stop button for the engine.
