What can be cooked from squid: quick and tasty

The favorite material in construction, in the manufacture of utensils for the home and household, as well as a variety of decorative items, furniture, etc., like hundreds of years ago, is wood. And the owner, who has the skills to work with equipment and skilled hands, can make a sawmill with his own hands.

This will allow you to be able to harvest boards and other sawn timber on site according to your own needs, the right size and type, and it will be much cheaper than buying finished products... This is especially true when it is necessary to process a large number of boards and other sawn timber.

Although it is generally accepted that the best option there will be an acquisition of a ready-made sawmill, but it is also possible and affordable to make it with your own hands if there is a desire and minimal working skills. Based on this, it is worth understanding the question - how to make a sawmill on your own, so that it is reliable, convenient, safe and meets the requirements for these specific purposes.

When setting a task for yourself to make a sawmill with your own hands, you should first of all decide on the amount of work for which this unit is planned to be used, as well as the type and geometry of wood (raw materials). Based on these parameters, you can already choose the type of sawmill that is best suited for solving the tasks.

When designing and manufacturing a mini-sawmill with your own hands, maximum attention should be paid to safety - any equipment of this class is high-risk equipment and requires a very careful attitude towards itself.

The presence of a sawmill is invaluable in the household of a master who often works with wood, because it will help solve such non-trivial for self made questions like:

make a significant number of products of the same size and shape;
cut logs according to a predetermined pattern.

In industrial sawmills, logs are processed according to two standard schemes:

Sawing a stationary log with a cutting element mounted on a mobile trolley;
The log is pushed (or pulled) on rolls or rollers through the cutting stationary block.

When self-manufacturing a sawmill, both of these schemes are used, and its specific type is selected depending on the design planned for assembly.

If we talk about the types of sawmills, then the main ones are angular, tape, chain. Additionally, when it comes O homemade units, it is worth highlighting devices using a chainsaw as a basis. Each of the listed types has a number of features and design differences from others, therefore, requires separate consideration.

Important! For the manufacture of a high-quality, reliable, safe and efficient machine on their own it is imperative not only to carefully select the type, scheme, material and details, but also to work out and prepare drawings that must be strictly followed.

Sawmill belt type

The general principle of operation of a band sawmill is that a trolley with a band saw blade moves along a log rigidly fixed on a stationary platform, cutting it. The location of the sawing part of the tape is horizontal, and the tape itself is well stretched. By adjusting the height of the band saw, the size (thickness) of the sawn part of the log (boards, beams, etc.) is calibrated. Such a device can usually work with logs weighing up to 300 kg.

Assembling a sawmill of this type on your own is quite difficult, since achieving coherence in the operation of all elements of the unit is a difficult task. In addition, for the installation of the structure, it is necessary to select special components, tools and devices, draw up rather complex drawings, taking into account all the structural elements.

The assembly of the complex must begin with the preparation of a level site of a suitable size and compaction of its surface (if it does not have a hard surface). The next stage of work will be the assembly of the unit frame, which should begin with the manufacture and installation of rails for the trolley. As a rail, you can use a corner installed with a shelf up.

Sleepers from a pipe, channel or angle are welded between the two rails to securely fasten them to each other. A movable fastener for a log is adapted to the sleepers, which must reliably fasten wood of any (within the planned processing) diameter.

Now it is necessary, according to the prepared drawing, to assemble and install a mobile cart on the rails and check its course along the entire length of the working area. The circuit will also require wheels (you can use car assemblies, along with cameras and tires), which are used to tension the band saw. It is their installation on the frame that is the next stage of installation.

It remains to mount the electric motor, connect it by means of a pulley to the unit mechanism and check the operation by a test run.

After checking the operation of mechanisms and parts, you can install tension band saws, make adjustments and test run of the sawmill.

Chain type installation

A do-it-yourself tire sawmill in its principle of operation is very similar to a band saw, but in quality cutting element it does not use a tape fabric, but chain Saw.

However, it should be noted that its design is much simpler, the installation itself has smaller dimensions, a smaller number of parts requiring significant adjustment are used - this together makes a mini-tire sawmill easier to independently manufacture and use than a belt one.

The beginning of the manufacturing process also begins with the preparation of the working platform, on which the metal frame of the future sawmill is installed in such a way as to provide free access to it from any side. A frame is assembled from profiled metal, in which technological holes are drilled (the amount will depend on the required step). Now you need to mount the bed with stiffeners. As a result, the base of the machine is assembled.

A movable trolley is assembled on the frame, installing stops, gaskets, clamps and an electric motor. Having checked the operability of all parts and structural elements, you can install and tension the saw chain and make a test cut, make adjustments and start working.

Mini-sawmill angular disc

A hand-made angle disc sawing unit is very useful in a home workshop for processing wood into different type lumber. Perhaps this is the most versatile and powerful mini-sawmill - you will not be able to make a more complex structure with your own hands.

Important! The design of an angular circular sawmill is most optimal for self-production - units of this class have a very high price and inaccessible. In addition, it is multifunctional and can handle very large quantities of raw materials.

After preparing the drawings and acquiring all the necessary units and structural elements, you need to prepare, as in previous cases, the installation site. The base frame is assembled on it, the material for which is taken from metal pipes and guides of increased strength (the design assumes heavy loads, and the material must correspond to them).

The guides for the mobile platform should ideally be made of rails, again due to the increased loads. The next step in the assembly of the carriage should be characterized by increased attention to the maximum adherence to the dimensions according to the drawing.

As a transmission of torque, it is best to use a chain, although with insufficient thoughtfulness of the design, this can lead to increased heating of the transmission mechanism. For safety reasons, all moving parts of the drive must be guarded or protected by a cover.

Chainsaw as the basis for a sawmill

Chainsaw is available from most craftsmen who constantly work with wood. Due to the availability, low cost and simplicity, it is quite easy to make a sawmill from a chainsaw with your own hands. There are a lot of options for a mini-sawmill, the main element of which is a gasoline saw, but all of them are distinguished by simplicity, small size, mobility (it can be easily transferred from place to place).

Important! In the overwhelming majority of cases, individual craftsmen do not need heavy-duty installations and huge volumes of raw materials processing. Therefore, from the point of view of ease of assembly, cost price, ease of maintenance, a do-it-yourself sawmill from a chainsaw is the best solution for your own farm.

To make a mini-sawmill from a chainsaw, you will need the following components:

channels;
metal corners;
rails;
chainsaw as the main element.

At the place prepared for work, which, if necessary, needs to be leveled, a frame is assembled with holes for fasteners and ties from metal pipes... Fastening is done with bolts. The angular dimensions must be constantly monitored to maintain exact perpendiculars (right angles). Additional stiffeners should be provided in the structure, which will strengthen the structure.

The basis for the mobile platform is a metal plate with two corners welded on the bottom side. This base is mounted on rollers (bearings are better). On the top of the plate, corners must be welded to which the chainsaw will be attached.

The last stage is the installation of the structure for reliable fastening of the log when it is cut.

As practice shows, even if you have not too great skills in construction and mechanics, the sawmill is not very difficult to make with your own hands. The main thing is attentiveness, strict adherence to the data indicated in the drawing and "straight hands". During operation, it is also necessary to observe safety measures, since the technique of this type refers to high-risk.

Large-scale works using wooden beam or planks, such as the work of a carpenter or self-construction at home, associated with the need for regular sawing of untreated logs. Of course, you can buy ready-made lumber or purchase an industrial sawmill, but this is expensive. This article tells (based on real experience) how a band sawmill was made with their own hands at relatively low costs.

It is quite possible to do this and you will get a reliable structure that allows you to saw a tree trunk into separate boards of three meters or more in length. You will need some materials (long products and parts of old machines), as well as carry out locksmith, welding and turning work. Everything was planned to minimize the need for turning work.

The "sleepers" of this design were a profile pipe 25x25 mm in size.

Between these profile tubes, a half-inch pipe is welded, and claws are already attached to it - fasteners for the log. These claws freely tilt and move, and when it is necessary to fix the log, several hammer blows are made on the clamps, as a result of this self-wedging of the fixing mechanism occurs.

When the band sawmill was made with our own hands, the profile tubes (“sleepers”) were made so that they protrude beyond the rails. The protruding parts are equipped with screws (M14 x 100 mm) for adjustment. In addition, “bridges” are made on the profile pipes - lintels on which the log is placed before processing. In case of workpieces of small length, the last two jumpers are installed at a distance of half a meter one after the other.

The pulleys were sharpened so that the worn belt protruded a few centimeters. For the pulley housings, the hubs from the Moskvich car were used, welded to the tubes.

All this together moves along guides - horizontally located half-inch pipes, and, if necessary, with the help of bolts, this unit is fixed.

When aligning the pulleys, you may encounter unexpected problems that will cause them to be cut off and welded again. This is due to the fact that, in practice, the installation of pulleys "according to science", in parallel, leads to a slipping of the tape during operation. So, it is better to install them with a slight inclination, up to 4 degrees, then the tape in motion will "pull itself" on the rollers.

The driven pulley is right, it is tensioned automatically by a spring. In this case, a spring was used that was dismantled from the KaSika motorcycle. And the leading, left pulley is fixed rigidly, but it can be displaced if the size of the band saw changes.

In the sawmill, hardened rollers must be used. In the variant described in the article, a roller assembly was used, which is easier to make on your own and be sure of its reliability.

This unit consists of three bearings on one axis: two - brand 202 and the third one, standing at the back, is 2-4 millimeters larger. The shaft with rollers is machined taking into account that when changing the width of the saw, install washers between the bearings.

The shaft fits into two tubes: half-inch and the second, into which the half-inch is inserted. In a half-inch pipe, the shaft is axially offset, in fact, welded to the bottom wall. This entire shaft and tube assembly is attached to the guides in such a way that the roller assembly can be adjusted in height, shifted to the side, with different log diameters, and securely fixed after adjustment. On the side of the driven pulley, a dropper is installed on the roller, supplying lubricating-cooling liquid (coolant).

The frame itself, one and a half meters high, is made of channel number 100, and for additional rigidity, the structure is reinforced with kerchiefs. The block for cutting can move along the channels by means of studs-screws. And the rigid fixation of the cutting unit in the sawmill is provided by bolts with a locknut.

So, as you can see, equipment such as a band sawmill with your own hands can be made even in a small home workshop or garage. Thus, a carpenter or summer resident will have the opportunity to dissolve large blanks on boards for their needs right on their site, or even earn a little - take orders for sawing logs.

Wooden products and blanks from different breeds timber is considered the most demanded product for repair and construction. And if you calculate the cost of lumber, as well as the price of processing and transportation services to the destination, you can guess where and what you can save on.

And based on the fact that it is quite simple to process wood, many people prefer home sawmills, which allow you to give the material any shape and appearance directly on the site. Guided by ready-made diagrams and drawings, you can create a truly productive device that will expand your capabilities and allow you to carry out various operations without going to professional workshops.

The feasibility of the desire to make a band sawmill with your own hands becomes obvious after viewing the prices for factory equipment. Of course, such models are available in a wide variety, but their cost exceeds hundreds of thousands of rubles. And this is if we talk about the representatives of the budget segment. More advanced and powerful ones are very expensive.

General characteristics

It's no secret that wood is one of the most popular materials in private construction. Despite the rapid expansion of the range of such products and the emergence of a cheap alternative, wood is still in demand and has no analogues. And even though the acquisition good stuff in a hypermarket it is not considered a difficulty, because solutions in the form of boards, beams or slats are available in every building materials shopping center, the opportunity to make such products at home looks much more attractive.

This is not strange, because in this case you deprive yourself of many costs, and the only thing you need to buy is a business forest. But trimming lumber is very expensive. Naturally, buying your own sawmill to touch up repairs or renovate the roof is unwise. If you intend to build some kind of structure on a clean site, then here sawmill can be a very useful solution. And if you still try to make it yourself, this will make the costs minimal.

Several key modifications of such equipment are in use today. However, if you intend to make a homemade sawmill, then most likely you will need to choose between two main types:

option with fixed saw placement,
version with a trolley, where the workpiece is fixed.

It is she who moves along the rails in the process of work. Any other varieties are upgraded versions that greatly simplify the task and provide the maximum quality of work. Take a mobile saw as an example.

Dimensions of the structure depend on the location. It's no secret that all plots (adjoining, summer cottages, etc.) have their own characteristic layout, so the choice optimal sizes the machine must be approached with great care. Any drawings available on the network (relevant literature, Internet resources and other sources of information) play the role of "landmarks" - in terms of individual components, parameters and other properties. A homemade sawmill is made in such a way that it was comfortable to work v specific location under specific conditions. In most cases, such solutions are exploited for breaking up logs and trimming boards.

Important features

A homemade band sawmill has many advantages. Among them - the possibility of continuous improvement and improvements, which allows you to more accurately "adjust" its characteristics to the growing requirements of the owner. For example, if initially you planned to dissolve logs into planks, you may soon need to start your own production of timber.

Such a structure is assembled by a block-modular method. If you do not have practical experience and skills in the construction of complex mechanisms and assemblies, start with simple drawings. The mechanically driven version is easy to equip with additional automation parts. Among them:

Cutting thickness regulator.
Saw feed regulator.
Programmer and many others.

Therefore, you need to understand the basic instructions for drawing and assembly.

As mentioned above, today a large number of modifications to sawmills are used. When choosing a suitable solution, you must ask yourself - in which plane you plan to conduct the cut. It is this aspect that indicates the placement of the working structure. The next question is to choose a single-type or universal type of sawmill. For example, if you have to trim logs into separate segments, and not just the basic breaking up of timber into planks, then it makes sense to opt for universal equipment. It is very good if the working frame supports reinstallation.

It is no secret that logs processed by a band sawmill are characterized by large dimensions and impressive weight. In addition, the frame is subject to intense stresses during machining operations, so you must pay special attention to the stability of the band saw equipment. In this case, you do not have to worry about the quality of the cut and the safety of workers.

Making a sawmill at home with your own hands is not as difficult as it seems initially. Many difficulties arise in people already at the next stage - preparation for operation... The most key nuisance is setting and sharpening the saw.

Seat selection

If you have a special workshop or room where all processing activities are carried out, it is advisable provide at least 18 square meters working area... In such an area, it will be possible to dissolve even the largest logs.

In private workshops, an empty structure, or at least one of its compartments, is often allocated for the installation of a sawmill. Sometimes woodworking activities held in the open air, but you are unlikely to live with neighbors who will normally react to a lot of sawdust and small shavings flying with the wind. And not everyone will be happy to see how the area near his house is quickly littered with various garbage.

In order not to become a victim of such a nuisance, it is enough to take a responsible attitude to the construction of the fence. solid type... You may find the option made from polycarbonate sheets or durable plywood.

In addition, you need to prepare in advance storage area for finished sawn timber... As a result, a suitable plot of land should be selected for storing the final product.

These issues should be resolved even before the design of the structure begins.

Selection of materials and components

If you are seriously thinking about making a homemade band sawmill, be prepared to pay due attention to the selection of all parts and materials.

The first thing to do is pick up the engine... In most cases, gasoline or electric units with appropriate power ratings are used. If you look at the situation from a practical point of view, then asynchronous (electrical) models are the most optimal. This is due to the fact that they have no problems connecting to the home electrical network, and besides, their service life is quite long. And the stability of revolutions ensures the maximum quality of cutting logs on the sawmill.
Materials (edit)... It is no secret that high-quality products made of durable metal should be used for processing huge wood. For example, it is customary to install a workpiece from a profiled (thick-walled) pipe of square or rectangular cross-section on the moving part of the "trolley". But the support frame is made from a channel, which is associated with the cumulative loads. Based on this, the rails are mounted from a clearance angle (at least 45), although a channel is also effective here, but with less linear characteristics.

Equipment for work and assembly algorithm

It is no secret that when building a homemade sawmill, you cannot do without good welding equipment. Bolted connections are useless in this case. It is better not to risk it, because after some time such a mount will lose its previous strength, loosen and make the structure dangerous to use. And tightening the bolts and monitoring their condition on a daily basis is not the best prospect.

As for the equipment assembly algorithm, it remains very simple and straightforward. The main difficulties are with the fitting of the component parts.

First of all, you must carry out the installation of the support platform, along which the cart with lumber will move. In addition, a frame must be attached to the rails, where the working tool will be installed. Key requirements include reliability and horizontal alignment. Where and how to fix it is up to you. It is possible to use a specially equipped foundation, for example, a columnar one, or an option with racks that are dug into the ground.

The purpose of the mobile unit (trolley) has already been mentioned several times. To ensure reliable fixation of the log when sawing, the movable element is equipped with "Clamp" which securely grips the wood to the frame and prevents any risk of displacement. Also, the cart must have wheels that will provide mobility.

As for the saw frame, it should be equipped with a good adjustment mechanism. Otherwise, there will be difficulty in providing the ability to change the position of the cutting units.

A number of engineering solutions are currently in use, so which one to choose is up to you. Drive specific examples it makes no sense without first studying the existing modifications.

Conclusion

Not everyone can afford to buy a ready-made sawmill, and even its payback very small, and then when it comes to commercial use and standing orders. Therefore, it is inexpedient to acquire such expensive equipment without knowing whether it makes sense. Can you make a design yourself? What difficulties can arise during the assembly process, and what to expect from the upcoming work for a novice DIYer who decided to cut raw logs at home?

As mentioned above, the process of making a homemade sawmill can be quite simple and straightforward, provided that you responsibly study the instructions and drawings. The main difficulties may lie in the selection of suitable components, a wide range of turning and welding works, as well as the need to set and sharpen the saw in a special way. True, if you observe all the subtleties of care and maintenance of the sawmill, it will be able to conscientiously work for its owner for many years, ensuring the maximum quality of work.

The general features and the procedure for making a homemade sawmill are considered. Experts recommend to determine in advance the type of tasks that will be solved on the equipment. Only after that you can proceed to the installation and assembly of the structure. To simplify the work ahead, you can download and study ready-made drawings that are freely available on the network. In this case, you can quickly and efficiently assemble the installation with different sizes, taking into account the scalability. You can also use the ready-made guide, but apply your changes to change the configuration or expand the set functionality sawmills.

In any case, if you adhere to the basic principles, take into account the advice of professionals and avoid irreparable mistakes, deviating from the instructions, you can create a highly efficient device that will allow you to solve many tasks for wood processing at home.

The chain sawmill is an indispensable tool for any builder. Not a single major repair will do without it. This tool is especially relevant for those who live in the private sector and often face construction and renovation problems.

What is a chain sawmill?

The principle of operation of a chain sawmill, to a certain extent, resembles a band apparatus: the log to be sawn is firmly fixed, while the sawing is carried out by the saw. The saw is attached to a moving carriage. The only difference between a chain saw and a band saw is that in this version only a chain saw is used, not a band saw.

The main disadvantage of a chain sawmill is its lower productivity and economy compared to band saws. Despite such disadvantages, people use such machines precisely because of its low cost and convenience, and real craftsmen create chain sawmills with their own hands. Someone wants to save money, and someone just wants to make a machine that fully satisfies all the individual wishes of the master.

DIY chain sawmill

What do you need to create a chain sawmill with your own hands? To begin with, you should look at the drawings of the chain sawmill on the Internet. Drawings are different, but any such sawmill consists of a chainsaw, a steel frame and rail guides.

In order to create a chain sawmill, you need to firmly attach a metal frame to the saw bar. The gap between the chain and the frame will be equal to the thickness of the resulting lumber. For this reason, you need to decide in advance what kind of lumber you need. By the way, if you make the distance between the chain and the frame more, then you can create not only boards, but also a bar.

An excellent bed will be obtained from two steel channels, each 8 meters long and 0.14 meters high. In addition, you can use rails or metal corners. We need blanks of perfectly straight shape. Along the entire length of the channels, you need to make holes with a diameter of 14-16 millimeters at a distance of up to 1.5 meters.

According to the number of these holes, you need to make from segments water pipe special screeds. All parts are secured with threaded studs or bolts.

After that, you need to assemble all the components of the chain sawmill into a single device and install it on the racks. The number of racks depends on the dimensions of the bed. The most recent posts should be no more than 1 meter from the end of the rails.

To give greater rigidity, you need to fix the braces.

After that, the movable trolley is mounted. It can be created from a steel plate with a thickness of 4 to 6 millimeters, and a length of about 0.6 meters. The size of the cart depends on the dimensions of the electric motor.

Next, you can proceed with the selection of gaskets and clamping plates for the trolley. The elements must guarantee the free movement of the mechanism. At the same time, the gap should be minimal. It is worth tightening the gaskets with bolts.

It is imperative to eliminate the lateral backlash by mounting the stop angle to the base of the trolley. The trolley can be put on bearings or rollers. Please note that bearings should be used new, used ones will definitely not fit.

Tighten the chain as much as possible. The steering wheel is mounted on one of the side sprocket bushings located along the perimeter of the rails.

In order to create a fixing device for a log, you need to take pipes with a diameter of 3 - 4 centimeters, insert into them movable rods that enter the stopper at the required height with an M8 screw.

On top of the rods, clamping parts are attached, the length of which is at least 1.5 cm, as well as cam clamps.

After that, you can install an electric motor and a saw, the diameter of which is 1 meter. The choice of a chainsaw for a home sawmill is also not an unimportant process. The chainsaw must have high power, high efficiency rates. In addition, her chain must be well sharpened. Making a chain sawmill with your own hands is not difficult. But remember that in addition to making the machine, it is important to ensure safe operation.

This is how "home" chain sawmills are created. A video of the manufacturing process of such a sawmill is presented below.

Work safety

With their high productivity, sawmills are sources of increased occupational injuries. Many people have heard horrible stories about “turned my head away, but my finger is gone”. There are many similar stories and they are all real.

The most reliable method of reducing the number of injuries and accidents while using such equipment is to scrupulously adhere to all safety rules. Before starting work, you need to familiarize yourself in detail with the principles of operation and operating instructions for such a device, as well as with the rules of fire safety.

The highest level of safety is achieved when the sawmill is equipped with a reversible feed system due to its design.

Chain sawmills, video

Edged board is an environmentally friendly and easy-to-handle material, but the cost of 1 cubic meter of high-quality wood will be quite expensive. In the case when you need to purchase a large number of building materials, many home craftsmen think about making lumber on their own.

For self-production of a high-quality board or timber, you cannot do without the use of special woodworking devices. The new equipment will cost tens of thousands of rubles. Therefore, if you want to do self-production such a device, the article will describe step by step guide how to make a band sawmill with your own hands with minimal financial costs.

A band sawmill is a machine that cuts logs longitudinally. Thanks to the ability to precisely adjust the position of the cutting surface, it is possible to produce lumber of various thicknesses.

The sawmill design consists of the following main elements:

Saw band.
Clamping mechanism.
Frame movement mechanism.
Web height adjustment devices.

An electric motor with a power of at least 5 kW is installed on the machine. A sawmill can be made with an engine from a walk-behind tractor, but the noise of such an installation will be much higher than when using an electric unit.

During the operation of the installation, the torque is transmitted by means of a belt drive to the working pulleys, on which the saw band is installed. The saw mechanism must be designed with a spring or hydraulic tensioning device to automatically adjust the width of the pulley extension to compensate for the thermal expansion of the metal band during operation.

For processing round wood, frame with fitted band saw and power plant moves along the fixed material on rails mounted on a concrete base. Adjustment of the saw blade height relative to the lower point of the sawmill is carried out by a screw mechanism, which is designed in such a way as to exclude the possibility of distortions during the operation of the unit.

To securely hold the log during the operation of the sawmill, the workpiece is placed between the guides and fixed with special hooks. After laying and fixing the log, the operator makes a smooth movement of the moving part of the installation, during which the upper part of the log is cut off. After completing one cycle, the cutting surface is lifted and the frame moves to its original position.

When using a homemade sawmill, you will need to manually move the carriage over the log, while the factory settings allow you to almost completely automate the process of making lumber. The quality of the timber or board, with the correct manufacture of the sawmill with your own hands, does not differ from the materials produced on modern equipment.

What you need for a homemade sawmill

It is possible to independently make complex devices and mechanisms from metal only if you have the skills to use it. Do-it-yourself band sawmill cannot be mounted without welded joints.

except welding machine you will need to prepare the following tools for work:

Electric drill.
Drills for concrete and metal.
Pliers.
Spanners.
A set of locksmith clamps.
Building level.
Nuts and bolts.
Concrete mixer.

To make the base of the sawmill, you will need a concrete mixer. In the absence of a factory model, the device can be made independently from a steel barrel.

To install a homemade woodworking plant, you will need to purchase the following materials:

Metal corner 50 mm.
Rollers or ball bearings.
Profile pipe.
Steel pipe.
Electric or gasoline engine.
2 long screws with nuts.
Chain transmission.
Wheels and hubs from a passenger car.
Cement, sand and crushed stone for concrete mortar.

When all the tools and materials are prepared, it is necessary to make drawings of the sawmill for wood.

Drawings for a homemade sawmill

To make a drawing homemade machine, it is enough to draw on paper a reduced copy of the woodworking device, indicating the dimensions of each part and mechanism.

When designing a band sawmill, it is advisable to set a length value of at least 6 and a width of 3 meters. Only in this case it will be possible to produce on homemade device lumber of standard length.

Based on the sketches of the woodworking installation, it will be easy to calculate the amount of materials for the manufacture of the frame and guide rails. In order to strengthen the structure between two parallel corners of the guides, transverse reinforcements must be installed, the distance between which should not exceed 1 meter.

If a do-it-yourself mini-band sawmill will be operated indoors, then you will need to make a drawing of only the main device. When placing the woodworking machine on open area, it is advisable to make a canopy, a drawing of which should also be drawn up before embarking on the practical implementation of this project.

Making the foundation

Only a properly prepared base for the sawmill will allow the frame with the saw mechanism to move evenly. The slab on which the guide rails will be installed is made according to the principle of erecting a conventional strip foundation.

The base must be poured out on a gravel-sand cushion with a thickness of at least 15 cm.

To increase the strength of the slab, a metal reinforcing mesh is laid on the base before pouring the concrete. After pouring the concrete, it must be cured for at least 2 weeks in order to achieve the maximum strength of the base.

Making a sawmill: step by step instructions

A self-made band sawmill with your own hands is mounted using wheels from a car, a belt drive and an engine.

A corner or channel is used as guides. The corner is used with a cross section of at least 50 * 50 mm. The material is laid strictly parallel, with the inner edge up, at a pre-calculated distance.

Then sleepers are installed between the corners, which are cut from shaped pipe section 50 * 100 mm. When welding transverse reinforcements, care should be taken not to overheat the guides, which could lead from high temperature... When the sleepers are welded to the guides, they are fixed metal structure to the concrete base using anchor bolts.

After the completion of work on fixing the rail to the concrete base, along which the carriage will move, a bed is installed in the middle part of the "railway" track for fixing the timber. To hold the round timber, an H-shaped stand with side protrusions is welded to the sleepers. The minimum height of the restraint rod must not be less than 100 mm.

Ball bearings can be used as rollers for the sawmill. For each axis of the frame, it is necessary to select 2 bearings of a larger diameter and 4 - 6 of a smaller one. The difference in diameter depends on the height of the corner rib. For example, if an angle of 50 * 50 mm is used as a guide, then the difference in the outer diameters of the bearings should be 100 mm. In this case, the inner diameters of the parts must be equal.

The manufacture of the frame begins with the installation of 2 rails from steel pipe... The guides are installed in a vertical position, after which sliders are mounted on them, the inner diameter of which should be minimally different from the outer diameter of the guide pipes.

The carriage frame is welded from a shaped tube. This element must be reliable design rectangular shape, on which vertical guides will then be welded, and in the lower part - an axis with bearings.

The movement of the carriage in the vertical plane is carried out using a screw mechanism, which is installed on both sides of the guide tubes. The nut is welded to the slider and the long studs are fixed at the top of the frame. In order to ensure easy rotation of the adjusting mechanism, it is recommended to install the studs on the bearings on both sides.

To ensure synchronous rotation of the screw mechanism, small bicycle sprockets of the same diameter should be welded onto each stud, between which a chain transmission is made using a bicycle chain. To ensure constant tension of the chain mechanism, its design must necessarily have a roller, on the lever of which a spring is installed.

Wheels and hubs from a rear-wheel drive passenger car will be used as pulleys in a self-made sawmill. To ensure easy rotation of the drive, it is necessary to assemble the bearing assembly, which will be welded on both sides to the cross member of the carriage. A pulley is installed on one of the hubs, to which torque will then be transmitted from an electric or gasoline engine.

To increase the safety of using the saw mechanism, a saw support unit is installed in the lower part of the carriage near each of the wheels, which consists of an axle on which several ball bearings of a small diameter are installed. From the side of the hub, on which the pulley was installed, the power unit is mounted.

If an internal combustion engine is used, a spring-loaded roller is used to tension the V-belt drive. To tension the belt in the case of an electric motor, the unit is installed on a small platform that can be moved horizontally.

At the next stage, a container for the lubricating-washing fluid is installed on the sawmill, from which it is necessary to bring the tube to the cutting unit. Then a casing is made of a metal corner and sheet metal over the cutting unit, after which you can start the first start of a homemade woodworking installation, having previously installed a band saw between the wheels.
