How to make a strip saw. Installation of guides
Assembly of homemade tape pylorama from plywood
Wood is a material in demand in construction: houses and household buildings are erected from the beam, floors are made from the boards, they finish the walls. For sawing lumber in domestic conditions, tape saws are often used often. Factory equipment models are not available to everyone due to a fairly high cost. But you can save by making a tape saw with your own hands. Depending on the size and the installed cutting canvas, it will also be possible to work with different metals and their alloys, stone, synthetic materials, for example, polypropylene.
Different variants of machines with tape saws are offered domestic inventors. For self.Assembly, a model of sawmill with a vertical location of the cutting canvas, consisting of the following main nodes and parts: is suitable:
These structural elements of the machine and smaller parts with basic sizes are schematically represented in the drawing below.
As a drive, electric motors operating from a network with a voltage of 220 V are often used very often.Over, the more massive it is planned to cut the workpieces, the more powerful it is recommended to install the engine. Three.Phase motors (designed for 380 V) are also used. But for stationary networks, this option is associated with some additional problems: you will need to adapt the electric motor to the 220 V network, installing a phase.Moving and start.Up capacitors for this. Instead of electric ones, it is quite possible to use gasoline (diesel) internal combustion engines.
Continuous cutting canvas is fixed on pulleys. Circling the blanks occurs due to its movement along the closed oval or circular trajectory.

You can make a small desktop machine. The model from an electrician is shown in the photo below. Focusing on it, collect the device will not cause any problems, even without a detailed description of the whole process.
Important! In general, the dimensions of the created equipment depend on the upcoming tasks that are planned to be solved with its help. For the dissolution of logs on a beam or boards, a large.Sized unit will be required. Owners of apartments with loggias are suitable only for a desktop mini-station.
Assembly of the frame
Gathering the frame of the strip saw, it is better to give preference to hard and strong wooden breeds. Otherwise, the final design will not have the required rigidity and begin to create vibrations. Separate elements, including the desktop, are made of durable plywood, and stiffener ribs are additionally enhanced by rails. The most affordable option is to dismantle old furniture.
First of all, at home, you need to draw up drawings on the basis of which the frame will be assembled. They are created taking into account the height of the working room and the physiological characteristics of a person who will work behind a saw.
What materials and tools will be required to make a saw
A set of tools and consumables for creating a tape saw with your own hands at home may vary depending on the features of the selected structure. But, as a rule, it is mandatory for the construction of the machine:
- Boards or sheets of plywood for the frame;
- Motor. Electric or gasoline;
- Metal corners;
- Metal cutting canvas. Homemade or purchased;
- Self.Tapping screws and bolts with nuts;
- Rubber from a bicycle chamber;
- Wooden bars and rails, they are needed for the supporting frame of the structure;
- Belt for transmitting a rotational moment;
- A steel rod that will serve as a shaft for pulleys;
- A steel sheet or a piece of textolite;
- Varnish or paint, they are needed at the final stage of creating a machine.
Also, in the manufacture of a tape saw with your own hands, you need to use the following tools:
- Corner grinder;
- Electric screwdriver;
- Wretched keys. Sizes are selected in accordance with bolts;
- A hammer.
Advice! When choosing boards for a table and a strip saw frame, it is better to take blanks of hard rocks with a thickness of at least 2 cm.
The choice of a tape canvas
If desired, you can make a saw canvas for a strip machine with your own hands from instrumental steel U8 or U10. The material should be durable, but flexible, with a thickness of 0.4-0.8 mm for sawing solid wood. When creating the canvas independently, you will need to cut the teeth in metal with a corner grinder, dilute them and then sharpen them, and then solder the tape with a gas burner into a solid ring and grind the seam.
The work is very long and time.Consuming, requiring certain skills. Therefore, the canvas is more often purchased in a store in a finished form. You need to take a tape with a width of 18-88 mm, depending on your goals. For cutting wood, carbide saws and canvases made of instrumental steel are suitable, they are quite reliable and at the same time quite affordable in price.
Homemade tape sawmill
We make a reservation right away. It is very difficult to make a strip sawmill yourself. The point is not so much in components, extensive turning and welding, the need to sharpen and wiring a saw in a special way, and in the debugged performance of the entire complex.
It is necessary to ensure loading and stability of movement of up to 300 kg of one log, adjusting the thickness of the incision, and most importantly. Safety precautions. But if the presence of free wood won, we make a tape sawmill with our own hands.
Let us explain the principle of strip cutting using the example: take two coils from the threads, pull the covered thin tape between them. Forcibly rotating the tape. Cut the log, the distance between the ribbons. The maximum size of the beam. It is convenient to cut the boards with tape saws.
We start with the choice of production area or premises. At least 3×6 m, verified. The second most important is the metal wheels of the cart and the strip saw, this must be found or buy. Ram a strip mechanism with wheels order, but it is better to buy a ready.Made. Self.Manufacture requires skills and a lot of high.Precision instrumental processing.

We install the guides. Any durable even metal: an I.Beam, a channel, a corner, under them through 0.5 m support or anchor for stability. The distance between the guides is the diameter of the largest log with a margin. About 0.7 m. Holding the geometry we weld everything together. We fasten the wheel on the cart, the frame of the tape mechanism, the electric motor through the pulley.
Think about the mechanism for changing the horizontal movement of the saw relative to the log. Moving the cart relatively fixed log, cut the horizontal layer of wood. We make boards.
Tools and materials
To create the type of saw under consideration, the following tools and materials will be needed:
- A piece of plywood, having a thickness of about 1.5 centimeters;
- A beam made of a wooden array;
- Ribbons or nozzles that will be used for an electric screwdriver or a grinding machine;
- A pair of bearings for the axis of the leading type;
- Studs, washers, screws, nuts, footer;
- Pair of shafts;
- Bolts that will be used to adjust vertical and horizontal types;
- A pair of braid bushes with an internal type thread;
- PVA glue;
- Bearings for the axis of the upper type;
- Lamb for tuning screws;
- Insulating tape.
Separately, it should be noted that for the correct creation of certain parts of the saw, you must have drawings. You will also need the following components for work:
Types of strip saws
The tape.Saw tool can process:
For solid materials, it is recommended to use equipment reinforced with super.Strength alloys: the cutting tape will not break, spoil the processed part. Before buying, the front of the work is determined, which is planned to be carried out using the installation.
With a large amount of work, a powerful, hardy saw is required that can withstand increased loads. Its cost will be high. For a one.Time procedure, rare use is suitable for cheaper equipment, with standard strength characteristics.
Width, length is selected according to similar parameters of the machine. Recommendations for the selection of components are in the instructions for the unit.
- Wide strip saws have more even sawing, they are more often used for longitudinal cutting.
- The thinner the workpiece, the higher the likelihood of damage it with a thick saw.
- When carrying out curly and contour cutting, the width of the cutting element should allow the product at a given angle. Release this type of tools with a width of 14–88 mm. For standard work, the average parameter is suitable. 35–40 mm.
Step of teeth
The distance between the pointed saw segments correlates with the response part of the unit.
- Thin sheet material is treated with a saw with a large uniform pitch of teeth.
- Frequent constant step is suitable for working with large canvases.
- Varias of teeth are designed for cutting natural and synthetic materials with a soft structure. Cutting speed increases, since the saw does not clog.
The quality of the cutting depends on the wiring of the teeth, the level of vibration during operation, the wear resistance of the main element. The canvas can have a different profile:
- Wavy. Used for small blanks, thin materials.
- Standard. Differs alternatingly the location of all cutting elements, one segment is placed in the center. Choose for processing volumetric blanks, contour cutting, installation on a vertical type of machine.
- Variable, or group. Contains in pairs located. The unit costs more: it is more durable, effective, has a reduced load on the cutting edge.
Particular attention is paid to the quality of sharpening saws. Check how sharp the cutting segments are, whether the steel from which they are made is uniform, the evenness of the cutting line line.
It is necessary to find out whether the re.Sharpening of the saw is possible, how many cycles of updating the cutter are provided.

DIY ribbon saw will cost cheaper than its factory version. But to make everything correctly, you should first deal with the design itself. The strip saw is designed for sawing wooden blanks of large diameter. As a rule, with its help, boards or bars are made from logs.

The design itself is a frame on which an electric motor and pulley are mounted. The first is necessary for the rotation of pulleys, on which the cutting canvas is fixed. It is with its help that the blanks are cut.
Before starting work on creating a tape saw on wood, it is worth making a drawing. With its help, all further work will go faster and more understandable to you.

Next, prepare the necessary tool and material. For work, you will need:
- Metal corners, profile pipes, channel and rental;
- Electric motor;
- Pipes from old agricultural machinery. Those that have a diameter of 30 centimeters are best suited;
- Sheets of plywood or wood-made stove for creating a cabinet;
- The cutting canvas itself;
- Welding apparatus and locksmith
Previously, it is necessary to make a frame (according to the previously compiled drawing). It is made of a channel (100) using welding. The height of the frame should be about one and a half meters. It is also advisable to make a box under the frame, chips will be collected in it. Such a design is easy to make plywood or wood-based sheets of plywood.

We make a door
Next, I need to make a door. Whatever numbers on the sketch, you should always measure the size of an already made object for the most accurate fitting. So that the door was flush with the frame, I needed to lay slots for loops. When I fixed them, I clamped the door so that it could easily noted where there should be holes. Then I attached the loops to the frame with bolts. This will allow me to easily install the door to the perfect height.
Install the blade
The upper and lower bearings should be on the same line, and this fishing line for the trimmer should be perpendicular to the base.
You can slightly adjust the angle of inclination of the wheel, if it is not perfect
There is no quick adjustment of the angle of the upper wheel
Grozes for locking screws of bearings
To level the upper wheel perpendicular to the base, I glued a temporary sheet of plywood and used several squares and a ruler. Just don’t forget to pre.Polish the details so that they glide smoothly.
Before installing the blade, I added two layers of island so that the blade does not slip. And finally, for the first time I saw that the blade was going perfectly in the middle. This is an extremely exciting and soothing moment.
If necessary, you can change the angle of inclination of the wheels by slightly changing the position of the rear bearings. The blade should be right in the middle and be a perpendicular base, in our case there is a place for maneuver, so you can easily do it.
While the position of the blade looks great. Regardless of how I pull the blade, it remains mainly in the middle. This indicates that the frame is tough and almost does not bend.
The reason I refused to adjust the angle of inclination of the upper wheel, which all commercial ribbon saws have, is that we are going to use this strip saw with only a few types of blades. Therefore, as soon as I set up a position for them, I no longer need to change it. I am still too lazy to change the blades, so why complicate everything, though? And if someday I need it by magic, I can very easily modify it, since everything is attached with screws.
They are easily accessible, and they are easy to align in places made. Meanwhile, the front I just tighten it tightly, since there is very little space there.
