A wood band saw has greater performance capabilities than a conventional one hand saw. This unit can be useful when carrying out carpentry work, at woodworking enterprises and sawmills. The choice of saw should be made based on your requirements and capabilities.
Manufacturers such as Bukhta, Corvette, Metabo offer a wide range of band saws, the blades of which are capable of working effectively on wood and allow the craftsman to achieve excellent woodworking performance with his own hands.
The selection is made based on several criteria:
- Scope of work performed and frequency of implementation;
- Functions, tasks that will be performed by a wood band saw;
- Characteristics of teeth;
- Canvas dimensions;
- Sharpening level and setting;
- Manufacturer.
Vertical installation of the Corvette, devices from Metabo have a number of advantages over homemade devices. Corvette with Metabo are among the leaders in the domestic market.
The choice largely depends on what material you have to work with. Metal work requires the use of an appropriate blade.
Working with metal involves using bimetallic blades. Bimetal cutting tools are excellent on medium and low carbon steels. It is possible to use bimetallic blades for woodworking, but it is better to equip the Corvette saw with a specialized cutting component.
Selection by scope of work
- For industrial purposes, where the work of the saw practically does not stop, the choice should be made in favor of powerful, productive models about Metabo, Corvette, Bay. Such saws have highly efficient blades, and the devices have excellent strength parameters.
- For DIY work living conditions, small workshop, the choice leans towards simple models Corvette, Metabo, which are characterized by medium strength, but are able to provide the required quality of processing with their own hands.
Canvases
The choice of blade should be made based on its length, width, performance characteristics of the Corvette, Metabo saw itself, etc. It is important to compare the parameters of the equipment and the cutting tool installed on it.
If you cannot find the information you need in the instructions, take into account a few key points.
- Thin canvases quickly deform if work is done with coarse products;
- Wide blades provide an even cut. The wider the canvas, the better the quality of the work;
- Thick blades are not suitable for working with thin workpieces. There is a great risk of damage;
- To perform figured cutting or contour processing, you need to compare the width of the cutting tool and its ability to enter the material at a certain angle.
Teeth
There are recommendations regarding the teeth of the selected band saw blade.
- A large number of blade teeth ensures high-quality cut thick-walled blanks.
- Blades with a small number of teeth minimize the load that affects the entire area of the sawn blade.
- Tools with multiple edges help distribute stress evenly throughout the band saw.
- Modern manufacturers produce blades, the number of teeth on which varies between 3-24 units.
- The large teeth of the blade are designed for deep cuts.
- If the edges of the blade are small, they can effectively saw thin-walled products.
- An equally important parameter for choosing a belt is the pitch of the teeth.
- A large pitch is relevant when processing thin sheet products small formats.
- Frequent steps allow the belt to cut through large pieces.
- Variable pitch is designed for working with soft materials.
Sharpening
Bimetallic, woodworking bandsaw blades need to be checked for sharpening quality. Proper sharpening is checked based on three parameters.
- Sharpness of teeth. The better the sharpening, the sharper they will be. You just shouldn’t check the sharpening level with your own hands.
- Homogeneity of woodworking material. If there are no blurs on the tape, the metal is homogeneous, then the sharpening should be of high quality.
- Uniformity of lines, correct angle. If the edges are sharpened well, but the angle between the cutting edges is broken, this will significantly spoil the quality of the product. The angle between the cutting edges must correspond technical specifications selected tape. Each of them is characterized by a certain angle and sharpening features.
Before purchasing a saw for DIY work, be sure to ask whether it is possible to sharpen the tool if it wears out with use. For most modern band saws, sharpening is a routine task. The instructions are not complicated, which allows you to do the sharpening yourself and get the correct angle.
But some saws have a strict angle, a clear angle between the cutting edges, if violated, the saw will no longer be able to return to its original operational capabilities.
Wiring
Setting is bending the cutting blade at a certain angle in different directions. Due to this, the level of friction is reduced and jamming of the blade is prevented.
There are several types of wiring.
- Standard. The standard set-up provides for an opposite bend at an angle of the cutting elements on different sides. This wiring is relevant for saws working with hard materials.
- Wavy layout. This complex design. Here divorce is characterized by variable meaning. The peculiarity is the formation of a kind of wave. Not the entire saw blade is bent to a certain angle, but some part of the top of the blade.
- The protective wiring consists of bending two cutting blades. The third remains in its place. A spread is used for belts that work with the hardest materials. Every third tooth has a trapezoid shape.
The setting is carried out so that the teeth have a deviation not exceeding 0.1 millimeters. If the alignment is not done, the saw will be positioned unevenly, which will negatively affect the performance of the band saw.
Homemade or factory
It’s not uncommon for craftsmen to think about making a homemade tape machine. Drawings are widely available on the Internet; reviews indicate the possibility of assembling the device with your own hands.
But a drawing alone will not allow you to assemble a band saw correctly. Homemade vertical installation It has whole line features that only an experienced specialist can master.
It is recommended to start with mini band saws, the assembly of which requires a fairly simple drawing. You can repair, modernize, and sharpen them with your own hands. cutting tools. Take it as a basis detailed drawing indicating all required assembly parameters. Having made a mini machine, you can gradually move on to more serious units.
Factory models are preferable due to the availability of such manufacturers as Metabo, Corvette. Corvette and Metabo companies offer a wide range of band saws, from mini to industrial. It is easier, safer and more convenient to work with them yourself.
If repairs are required, you can contact a service center, or perform the repair yourself according to the factory instructions.
Factory-made band looms are preferable to homemade ones. They win in almost all respects. The exception is the price. The estimated cost of a band saw made by Metabo, Corvette is from 20 thousand rubles.
It is used for sawing boards, beams and other similar materials. It is manufactured by many manufacturers who provide the equipment with the best performance characteristics. To save money, you can make this unit yourself.
What does it take to have an efficient band press?
A homemade tape machine is made according to ready-made drawings that are in the public domain. To perform this work, you need other things:
- find several car parts;
- select the appropriate rolled section type;
- correctly carry out all the necessary metalwork and turning work;
- carry out some manipulations using a welding machine.
To assemble band press, you can use unnecessary pulleys removed from old agricultural machinery. It is best if their diameter reaches 300 mm. It is recommended to use as guides metal pipes two different diameters. The first should be half an inch in size, and the second a little larger. As a result, one pipe can be put on another and obtain the required gap of 0.5 mm.
Making a base for the machine
The do-it-yourself woodworking machine is installed on a base made of metal corners. They are mounted in such a position that the vertical shelf faces upward. It is necessary to achieve maximum accuracy, which will prevent rapid wear of the impellers.
TO established corners racks are welded in a perpendicular direction from profile pipes(2.5x2.5 mm). Another element is mounted between them. It is a half-inch diameter pipe. It is on this that the claws are installed, designed to secure the logs. These devices must move freely in different directions. To fix the material, you must hit the clamp with a hammer, which will cause it to jam.
Installation of pulleys for the machine
The presented homemade product cannot work without pulleys. When assembling this structural element, you must adhere to the following rules:
- homemade pulleys are sharpened so that when putting on the belt it protrudes a few centimeters;
- the manufactured structure must move, which is ensured by the presence of horizontal pipe guides;
- to increase the reliability of the unit, it is additionally fixed with bolts;
- the pulleys are installed at a slight angle, which will prevent the belt from slipping during operation of the equipment;
- the right pulley is driven, so a spring is attached to it. During operation, it automatically tightens it;
- the left pulley is fixed rigidly, since it is considered the leading one;
- the diameter of the element is chosen arbitrarily, but the larger it is, the longer it takes not to change the saw;
- You can use a regular bicycle frame as a belt;
- For efficient work the machine needs to place two pulleys in the same plane as accurately as possible;
- To secure the upper element in a given position, it is best to use a self-aligning type bearing.
Recommendations for installing a roller assembly for a machine
A homemade wood band saw will work correctly and without failure when using hardened rollers. It is best to make the assembly that they are part of yourself. In this case, you can be confident in its reliability, which cannot be said about a ready-made mechanism. The design of this unit has the following features:
- The mechanism includes three bearings. Two of them are brand 202, the third is a little larger;
- The shaft and rollers are machined taking into account the use of saws of different widths. If necessary, install a washer between the bearings;
- the shaft fits into two tubes installed one inside the other, with a slight displacement of the axis;
- the roller assembly is installed on homemade machine with the ability to adjust in height or move to the sides.
Tabletop
Types of cutting elements
- wide saw blades provide high cutting accuracy. They are used for longitudinal sawing;
- The thickness of the cutting element must correspond to the thickness of the workpiece. Thick saws can damage thin material;
- by doing figure cutting the saw must have optimal thickness and width to process the workpiece at different angles.
Machine frame and other additional elements
To obtain a band saw machine, it is necessary to make a frame. For this, use 100 mm. The height of the structure is 1.5 m. To strengthen the frame, gussets are additionally used. The block itself, with which the logs are cut, will move along the channels due to the presence of pin screws. To securely fasten the cutting unit of the machine to its base, bolts with locknuts are used.
Other elements that must be present in the design of cutting equipment include:
- Electrical engine. You can use an old power tool (drills, hand-held power saw) as a drive;
- box for collecting shavings and wood dust. Made from ordinary wood or plywood sheet;
- a casing made of wood or metal that covers the upper pulley. Increases equipment safety.
Setting up the saw
A homemade bandsaw machine driven by a drill or a conventional electric motor will not work effectively unless the saw is adjusted.
This process follows the generally accepted scheme:
- the parallelism of the wheels relative to each other is ensured;
- to prevent displacement in the vertical direction, fluoroplastic washers are used, mounted on the shafts;
- the system is launched in trial mode without installing guides;
- test cutting is carried out without load;
- After completing the adjustment operations, a block is installed to form the direction of movement of the belt.
If the saw of the machine is adjusted correctly, the wheels move smoothly without jerking. Such equipment will delight you with its high productivity and accuracy, which is especially valued among craftsmen.
Many tasks can be completed using a specialized bandsaw created by with my own hands. Using the recommendations in this article, reproducing this device is quite simple.
1 - belt drive pulley (lower), 2 - base, 3 - band saw, 4 - V-belt A710, 5 - damper, 6 - guide, 7 - carrier rod, 8 - belt drive pulley (upper), 9 - table ( plywood s20), 10 - electric motor AOL-22-2, 11 - belt drive pulleys, 12 - bracket (steel angle 40x40), 13 - M12 nut (2 pcs.), 14 - upper support, 15 - adjusting screw, 16 - slider
The desktop of a homemade band saw (dimensions 420x720 mm) is made of 20 mm thick plywood covered with textolite on top. It is edged along the perimeter with hardwood slats. To guide the sawing band, narrow grooves are provided in the table. The base is a box measuring 420x720x500 mm, glued together from 20 mm plywood. Among other things, it serves as a place for collecting sawdust.
The supporting rod is a section of channel No. 8, 680 mm long, the flanges of which, for convenience, are cut to a height of 20 mm. The rod is attached to the table using a bracket made from a 40x40 mm angle and four M8 bolts. The saw belt drive pulleys are machined from 20 mm thick plywood. On the working surface they are covered with dense sheet rubber, joined at the edge. Polyurethane glue was used. After rubberizing the pulleys, the wood is impregnated epoxy resin, sanded and painted. Working surface the barrel shape necessary to hold the running saw blade is imparted. A duralumin bushing is glued into the upper pulley with epoxy resin, in which a seat is machined for a 60203 ball bearing. The lower pulley is mounted on an axle made of steel type 30KhGSA and secured with three 5x20 screws. The axle is inserted into an axle box with two ball bearings 60203, installed at the lower end of the support rod. At the other end of the axle, the driven pulley of the belt drive is fixed through a spacer bushing. After installation, balancing is carried out belt pulleys. The principle of operation and dimensions of the parts of the sawing belt tension system are clear from the given figures (section A-A).
Belt Drive Pulley (Upper)
The gear ratio of the belt drive from the engine is i=1, so the drive and driven pulleys are the same, with the exception of the mounting hole, which on the drive pulley depends on the motor shaft. The pulleys are made of duralumin. V-belt - A710 (in this design).
To eliminate vibrations of the sawing belt, a damper (vibration absorber) is provided, assembled from textolite parts on M6 bolts. The fixed element of the damper is fixed at the bottom of the work table, and the movable bar allows you to select the required gap. It should be noted that the band saw also has an upper damper, but its installation is advisable if the upper pulley of the saw band begins to “beat the diameter.” Otherwise, the upper damper only increases belt friction. It is similar in design to the main one and, if necessary, is mounted on the rod with M5 bolts using a special bracket 105 mm above the plane of the desktop.
1 - base, 2 - M6 bolt (2 pcs.), 3 - strip, 4 - nut with washer.
The guide for feeding the sawn timber is made of steel angle 100x100 mm. It is advisable to grind its perpendicular planes on a machine. Two grooves are made in one of the shelves along the edges to adjust the gap between the guide and. tape, and in the middle there is a cutout to increase the stroke of the bar. Safety during operation is ensured protective casing, covering the entire assembly of the upper pulley of the sawing belt, which exits the casing cavity only in the working area.
The saw blade itself deserves a lot of attention. It must be sufficiently elastic, on the one hand, and durable, on the other. For its manufacture, we recommend cold-rolled sheet steel grade U8, U10 or 65G with a thickness of 0.2-0.4 mm for sawing soft wood (balsa, linden) or 0.4-0.8 mm for more hard rocks. By the way, many people use steel tape measures made of high-quality metal with a thickness of 0.2 mm and a width of about 10 mm for these purposes. "Automatic" modern tape measures with a curved tape profile are unsuitable - only old samples are suitable. The length of the workpiece for the given dimensions of the machine is 1600-1700 mm. On the blank strip, teeth are cut with a file in increments of about 3 mm, after which the strip is soldered into a ring, the ends at a length of 3-6 mm are sharpened to a miter thickness. Then the place of adhesion is sprinkled with borax and warmed up on gas burner. PSR-40 brand solder is applied to the joint and the seam is tightly compressed with pliers with asbestos pads on the jaws (otherwise the joint cools quickly and the metal in this area becomes brittle). If necessary, the joint is sanded. To obtain a better cutting surface, the front and rear surfaces of the teeth are sharpened similarly to a hacksaw for wood and slightly set apart. Of course, you can also use commercially available blades for branded band saws, but then the dimensions of the machine should be made in advance in accordance with the dimensions of the purchased blade.
Considered homemade band-saw used for straight cutting of soft wood (balsa, linden, aspen, spruce, pine). You can also cut harder woods (beech, oak, mahogany) when installing a 0.8 mm thick belt on the machine.
Flaw this option homemade band saw - a small overhang of the blade, but this greatly simplifies the design. If the small overhang of the blade is not satisfactory, then in order for the overhang of the blade to be like that of branded band saws, you will have to make the arrangement of the support bar like theirs and use pulleys of a larger diameter.

A saw is an assembly tool that is used to cut wood, various metals and other exposed materials.
Tape is used in repair work for cutting, patterning and cutting various materials.
How to make a band saw at home?
First you need to analyze what material will be exposed to the saw, as well as the quality of the tool that will be used in construction. At the very beginning, it is worth checking the sharpness of the saw, its position in the hand and sliding on the material.
In order to make a band saw at home, you need to highlight all types of band saws:
- metal saw
- wood saw
- mini wood saw
The metal saw is made from alloys of various metals, the most common of which are steel, cast iron, copper and aluminum with tin. In order to select a material, use the following rules:
- Materials must be durable for construction work, and also they must be processed different methods necessary to create different shapes. (To do this, use gas or electric welding for cutting, bending and other actions).
- The material and the seams connecting it must be strong and resistant to action.
- The use of inexpensive and non-scarce materials is mandatory.
Now we need to consider the metals for creating band saws and its types. Steel tools usually divided into two categories:
- structural steels used in general construction
- special steels with special properties, such as: acid-resistant properties, heat-resistant properties
There are no universal steels. Steel may be resistant to corrosion, but not resistant to other factors.
Besides:
- Cast iron is used for casting large or small parts. The metal base of a band saw can be cast from cast iron, followed by sharpening the teeth, as well as cutting the teeth.
- Copper and its alloys are used in construction and repair because it has high corrosion resistance.
- Aluminum comes in sheets that are easy to cut into a band saw and sharpen the teeth at the bottom. But the main disadvantage aluminum sheets is low strength when cutting hard wood or light metal.
- Tin is used because it is resistant to organic acids. It is more used as a coating for steel or cast iron, against acids.
As the metal variety of band saws is described above, we can draw a small conclusion about its production at home. It is advisable to use more durable metal saws so as not to break when cutting hard materials. Aluminum band saws can be used for cutting, but be careful!
To make a band saw with your own hands, you need to purchase a sheet of aluminum (for example), cut it according required length and welding in the lower part to make teeth, with a certain step, for example 5 centimeters, and cut at the same distance. This is one way to make a regular bandsaw at home.
Mini sawmills made of aluminum are used for cutting transverse, longitudinal and circular sections.
Making a saw frame
To make a base, that is, a frame for a future saw, you need to make a drawing on a sheet of metal, which will show the indentation of the next tooth from the previous one. To make the teeth even, you need to bend each part of the tooth distance towards the next tooth.
Thus, all that remains is to cut these holes with stronger metal knives, and you will get straight teeth. In this way, you can make a band saw and a mini band saw with your own hands at home.
Upper pulley and blocks
First you need to figure out what a pulley is? A pulley is a wheel that is pulled in a circle with a belt. It is this action that provides movement only to the belt, and not to the pulley.
The main task is to assemble a “machine” for making a band saw with your own hands, build upper and lower pulleys with blocks and belts. The block is the frame that will hold the wheels, or pulleys. The fact should be taken into account so that the block can rotate freely and without interference and help the pulleys move.
To do this you should:
- first draw a drawing and understand the essence of the machine's operation
- then you need to attach the wheels, which can be made of wood or metal
- then holes are made in the pulleys on which the block will be placed together with the frame
Manufacturing of wheels or pulleys
There are pulleys different types, for one action or for many actions at the same time. Most often they are recommended to be made of cast iron or steel, but in modern times you can find wooden and even plastic ones.
If the option is only at home, then they use various electric machines for chopping and cutting medium-sized metal parts.
Cutting table
The location for sawing should be several times larger than the band saw itself, because the parts to be cut may be more tools. To do this, you need to find in advance the room in which the work will be carried out and install the device together with the saw at the same level. In this case, the pulleys themselves should extend slightly beyond the table. The table must be treated from pests, dirt and various substances.
The table should not interfere with the working person during cutting due to its dimensions. Most often it is made from pine or oak, but beech and other types that are highly durable can often be used. You should use wood that will withstand pests, acids and high loads from sawing.
Setting up the band saw
To set up a homemade bandsaw, you should carry out several idle speed on unnecessary material to make sure the machine is working properly at home.
It is necessary to tighten the belts onto the pulleys so that they are tight and taut. Make sure the block and pulley are seated correctly on the table surface. Check that the table does not wobble or break under heavy loads.
Observing everything technical requirements, you can be sure that the band saw will work correctly with your own hands at home.
Blades for band saws and other saws
The saw blade is the basis for homemade saw. Such sheets are most often ordered from special factories for the production of metal sheets for various actions.
Aluminum sheets are used the cheapest, but they have less density and stability. But, if you add some auxiliary substance to aluminum, you can get a more stable alloy. This needs to be addressed to the manufacturer.
It is best to use aluminum alloys with zinc or iron, as their corrosion is not toxic.
Do-it-yourself band saw - on video:
For a good owner, having everything necessary equipment- this is happiness. It is especially important to have various adaptations for those people who live in own home. For example, a homemade band saw will make working with wooden products. At the same time, as is already clear, the apparatus can be built by yourself from available materials.
Areas of application and unit design
In principle, the device is used in sawmills in industrial or domestic settings. It has certain advantages and disadvantages, but is used very widely.
The design of this unit is quite simple. The electric motor and pulleys are mounted on a stable frame. A cutting blade is attached to them. The engine ensures the operation of the device. Depending on the type of blade, you have the opportunity to cut not only wood, but also metals, alloys, and polypropylene.
Advantages and disadvantages of the device
A DIY band saw can be done quite quickly. Naturally, you need to comply with all the requirements of the drawing and be accurate. However, you must first decide whether it is worth doing. To do this, it is necessary to consider all the pros and cons of the unit. So, among the advantages we can highlight the following:
High level of productivity.
Low heat transfer.
Excellent work accuracy and high speed.
Possibility to produce blanks according to individual parameters. At the same time, you can cut not only in a straight line, but also in curved bends.
To make and use a tool you will not need a large number of Money.
3. Carbide. They can be used for cutting alloys that are quite difficult to work with.
4. Made from tool steel. Such canvases are most often used at home or in small workshops. They are best suited for working with simple materials.
Types of machines
Before you start making band saws, you should understand their types. There is such a classification of devices:
Toothless. They have high performance and can work with metal. The peculiarity of such devices is that they still have small teeth. They work due to friction and additional heating.
Serrated. They can be used for cutting wood or plastic. The peculiarity of the canvases in such devices is that they are closed.
Electrical search. Most often they are installed in large industries where large amounts of material need to be processed.
What materials are needed for manufacturing?
It should be noted that not the entire structure can be built from available materials. Therefore, before making a band saw, you should collect the necessary parts:
Screwdriver.
Bulgarian.
Screwdrivers.
Hammer.
Naturally, other tools may be needed. For example, a milling machine.
Instructions for the manufacture and assembly of the device
Now we should begin production of the presented unit. To do this you will have to carry out several steps:
1. If you decide to make a unit such as a band saw with your own hands, you should already have drawings. They are the key to success. You should start by building a table and a cabinet on which the mechanism will be fixed. For this you will need furniture board or tree.
3. Now you can make a frame to assemble the entire device. She may have C-shape which ensures good tape retention. The supporting frame is made of a channel onto which a steel axle is placed.
4. Now let's deal with the pulleys. They must be put on the axle using bushings, and at its different ends. Naturally, both pulleys must be balanced.
5. To prevent the tape from vibrating, it is necessary to use a damper.
6. All movable parts must be connected to the electric motor.
7. You can also build a guide mechanism with which the material being processed will be fed. Metal corners are used for this.
Features of setting up the device
Homemade must be carefully prepared for work. To do this, it must be tested and configured. The cutting tape must be at a strictly right angle. Any slight misalignment can stop the machine from working and become life-threatening.
Please note that the cutting tape should be as tight as possible. Use the driven pulley for adjustment. It is with its help that you can properly adjust your machine. It should also be noted that the welding of band saws used in manufacturing (it’s quite easy to do it yourself) will ensure good strength and stability of the machine.
Sharpening the saw
Naturally, any equipment needs periodic repair and inspection. For example, sharpening band saws with your own hands is quite simple. The main thing is to know its technology. A special machine is used for the work. All work consists of several stages:
1. Initial sharpening (eliminates existing cracks, restores the symmetry and profile of the teeth).
2. Cleaning the canvas from sawdust and dust.
3. Wiring (to restore the rear and front corners).
4. Final sharpening. It eliminates all distortion and sharpens the teeth.
If you do not have experience sharpening saws, then all actions should be done as carefully as possible. The quality of the device’s operation depends on this procedure. If you are not confident in your abilities, then invite an experienced specialist.
What problems may arise during the manufacture of the device?
First of all, you will need sophisticated equipment to perform some jobs. For example, not every master knows how to use welding machine. Not everyone has milling machines. Please note that the entire structure must be stable. At the same time, one should not forget about the mass of the material that will be processed.
Not everyone is able to understand the drawing. Please note that the disadvantage of such a device is the rather wide cut. In general, if you want to build such a unit yourself, stock up necessary tool, material and patience.
Features of using the saw
Even after you can make the presented design, you should learn how to use it correctly. For example, try to follow all necessary safety rules. Please note that in some cases the blade may burst, so if you are not sure of the strength of its fastening, then do not be too close to the machine.
Observe the following rules for operating the device:
The larger the workpiece that needs to be processed, the larger the teeth the saw should have.
It is better to use universal cutting belts. In this case, you will not have to change the blade every time you need to process some other material.
Before making the device, you must choose the place where it will stand. This takes into account the size of the room, the availability electrical wiring. Naturally, this place should be well ventilated.
Before work, try to tighten the cutting tape as much as possible. Otherwise, the machine will not only not perform its functions, but will also become hazardous to health.
The unit should not operate for more than two hours at a time. After this, the tape is removed and left alone for at least a day.
After long work The machine needs to be lubricated. Choose the right substance for your car.
Correct tooth alignment is required.
That's all the features of making and using a band saw. Please note that this device requires proper care. If you see that it is not working correctly, then it is better to wait until you start using it. Be careful and careful.
