How to make a shaft for circular with a bearing knot with your own hands and what can be bought on AliExpress
There are many ways to manufacture a stationary stand for a tree sawing, we will consider one of the popular. The most inexpensive and easy to manufacture is a machine with a wooden table. Here is a general manufacturing algorithm, but it should be taken into account that each master makes it for his needs, taking into account his needs. To make such a stand, you need to perform the following actions:
- At one end of a wooden beam, apply markings to round the angles. It is also necessary to mark the holes for the axes at the ends and in the center of the bar.
- According to the previously made marking in the center of the bar, from the opposite sides, to make a crown for cutting a tree for installation of bearings. Combine the formed grooves with a through jumper.
- Drill holes for the marking in the end and on the edge of the beam.
- In prepared grooves, press the rolling bearings. To do this, install the bearing in the planting nest and mount them in place through a wooden bar.
- Determine the center of the fasteners that will act as an axis.
- Mount the hairpin into the landing hole, accurately putting it in a central position. Fix its position using nuts and counter.Hawks. On the side of the installation of the saw disk, install two profile washers and fix their position with a nut.
- Prepare a small wooden beam. In one of its ends, drill a dull hole.
- From a sheet of OSB / plywood (depending on what you have chosen) cut out two rectangular blanks. On the corner of one of them, set the bar with a drilled hole inside. Fix his position with screws.
- With the help of metizes, combine the prepared OSB sheets / plywood.
- Combine a mobile bar with a beam on the end wall of the future stand.
- In the OSB sheet / plywood, which will play the role of another end wall outline the position of the longitudinal groove. Its center should coincide with the center of the hole in the end of the mobile timber.
- Electricity or other tools cut the groove.
- Combine the base of the machine and the prepared OSB sheet / plywood with a groove.
- After that, screw the hairpin into the hole in the end of the moving beam. Wind up a nut to the protruding end. For convenience, it is better to use a barack nut.
- From below the movable bar, symmetrically install and fix the rectangular panel cut out of the OSB / plywood sheet.
- On the edge of the installed panel, mount a metal half.Cooker. It is necessary to fix the drill, which will be used as the drive of the circular.
- From the OSB sheet / plywood cut the working surface of the machine. On one of the inner sides, to facilitate access to the saw disk, it is necessary to install door loops.
- Install a saw disk on a drive shaft.
- Turn on the drill. Slowly lower the working surface in a horizontal position. In this case, the rotating saw disc will wrap the hole required to work in the plate.
After the final stage, you can start work. With the help of a protruding hairpin, you can adjust the depth of the cut of workpieces.

Well, the most important thing is that the assembled node (shaft for circular saw) works without the slightest beat, it needs to carry out balancing in the factory on special equipment.
Sawing shafts of woodworking machines
Sawing shafts of woodworking machines
Saw shafts are used as working bodies in round.Fed, as well as aggregate machines. The saw shaft rotates in two ball bearings installed in the housings, with which the shaft is mounted on the supporting part of the machine (for example, on the bed). At one end of the shaft, a pulley is fixed, with which rotation from the electric motor is reported through the belt gear. At the other end of the shaft, a saw disk is clamped between special washers using a nut.
The puck is fixed on the shaft motionless usually with the help of a prismatic key. The puck is installed on the shaft on a sliding landing.
A nut that closes the washers and a saw disk should be wrapped in the direction of rotation of the saw disk, which eliminates the possibility of turning it off during operation. Therefore, depending on the position of the saw shaft, the thread at its end can be right or left.
In some designs of round.Fingered machines (balancer and pendulum end machines), both buildings of the ball shaft ball bearings are made in one casting, which is pivotally attached to the bed or is a whole frame that turns on a fixed axis.
In machines of other designs (CDC.5, CRM.2) several saws are installed on the saw shaft for cutting a board or blanks to several parts. Saw shafts in such machines are usually installed in the housing on bearings. A pulley connecting the shaft through the belt gear with the electric motor shaft is planted on one shaft console. The pulley is fixed with a key and a puck with a bolt. On the opposite console of the saw shaft, the saw is fixed. The distance between the two adjacent saws determine the spacer rings. Saws along with a sleeve and putting on rings are fixed on the shaft with a puck and nuts. The ears of the shaft case are hinged mounted to the machine bed. Turning the body behind the ear, you can change its position, and therefore the position of the saw shaft relative to the table of the machine.
Saws are fixed not only directly on the saw shaft, but also on a special mandrel-liner that has the opportunity to move along the shaft on a sliding veneer.
In many round.Fed and aggregate machines, the shaft of the electric motor serves as a saw shaft at the same time. This allows us to simplify the design of the machines and reduce their size by reducing the supports and excluding the belt transmission. In Fig. 2 shows two examples of fastening of such electric motors.
How to make a vacuum cleaner with your own hands
The vacuum cleaner is necessary to cleanse the working surface of the table of the circular saw from wooden sawdust. Their gradual accumulation during work harms not only the quality of work, but also the health of the master.
We will figure out how to protect our health and improve the quality of work by making a vacuum cleaner from a vacuum cleaner. In fact, the vacuum cleaner itself will be a vacuum cleaner, it will simply need to be completed and correctly mount it.
- The vacuum cleaner is installed under the table of the circular saw, so that for it there is access to 220v network.
- The corrugated duct may be simply carried out under the table or fixed to special clamps.
- The bell itself without a brush must be fixed from the side of the disk under the table.
If there is a need to increase the container for collecting waste from sawing, then you can remove all the filter elements from the vacuum cleaner, and install an additional corrugation to “discharge” air. We immerse the additional corrugation into a separate container for collecting.
The conclusion of additional corrugation to a separate waste reservoir
Reading this article gives users of circular saws not only knowledge about the correct selection and use of special devices, but also opens up the prospects for their independent manufacture. And in order to make a high.Quality vacuum cleaner for the circular with your own hands, it is enough to accurately comply with the instructions given above.

Do-it-yourself circular, made of disk saw or corner grinder: manual mini-station and stationary structure
Stationary circular saw is the machine that should be in the workshop of every craftsman working with wood. With its help, you can quickly and without much effort to cut the board, cut the workpiece of the required size, saw firewood.
The home master is simply obliged to get such a machine. It is not necessary to buy it, a home.Made circular is guaranteed to cope with the volume of work of a home workshop, while it will cost a much smaller amount.
Circular saw device
Being a really useful tool, the circular has a fairly simple design. Its main nodes:
- The bed is the frame on which the main units are mounted;
- A countertop with a slot for a disk;
- Engine with a rotation transmission system;
- Cutting tool, dick disk.
Optionally, the device can be supplemented by a pusher that provides progressive advance of the workpiece to the disk, and various lifting mechanisms that regulate the depth of the saw.
The principle of operation of the circular saw (circular) is that the rotation of the motor shaft is transmitted to the cutting tool, a disk with sharply sharpened teeth. The center of the disk is located below the level of the countertop, only its segment is displayed from it. The workpiece is brought to the rotating disk, the teeth bite into the wood, creating an even saw.
Simple circular of corner grinder or disk saw
An angle grinding machine (angular grinder) is one of the most popular instruments of the home master, with its help it is easy to cut metal, clean the welds. In addition, using a wood disk instead of a standard abrasive disk, an angular grinder can be turned into a manual disc saw (it is also called a parquet), and having made a bed with a table. Into a stationary circular.
- Multilayer plywood 10 mm or more thick;
- Switch and wire;
- Bolts with a hat under the hid;
- Wooden bar 40×40 mm.
It is also necessary to prepare a drill or an electric screwdriver, a hammer, a screwdriver, pliers, a ruler and a pencil. With the help of these tools, you have to make a circular with your own hands.
Of course, you need not to forget the angular grinder itself or manual disk saw. At the first stage, it will help to cut the material, and then it will take a place as a working body of the circular.
First of all, the Circular case is made. Fat plywood is perfect for this, you can use any pressed wood plates. It will be necessary to cut four rectangular sheets, size 40 x 80 cm. From them a box with a square of 80 x 80 cm is assembled at the base. Four bars are installed in the corners for simplicity of assembly and reliability of the structure.
On top the resulting box is closed by a countertop. It can be made from the same plywood, but it is better to use any leaf material with a laminated coating. This guarantees the durability of the machine, will ensure the convenience of operating a home.Made circular.
In the countertop, they make a cut to exit the disk, holes for attaching the tool are drilled on the sides of it.
Corner grinder must be securely fixed under the countertop. The design of the latch can be very diverse, it all depends on the configuration of the machine itself. The main requirement for fastening. It must reliably hold the angular grinding of.
The simplest mount may look like this: two metal squares, an angular grinder is fixed between them with a steel clamp.
For additional strength, it is recommended to use the thread of the side handle, a bolt with a suitable thread is screwed into it.
In the upper shelves of the squares holding the corner grinder, two holes are drilled. The design with bolts with secret heads is attached from the bottom to the countertop. It remains only to block the power button, connect the angular grinder through the external switch.
In the same way, you can make with your own hands a circular saw from a disk saw. In this case, the work is noticeably simplified due to the fact that you do not need to come up with the mount. It is enough to make a neckline under the disk, drill holes along the holes of the slab of a hand.Saw saw.
Miniature engine from a washing machine
The circular is extremely simplicity and availability of materials for its manufacture. Perhaps the only expensive detail is the electric motor. Stationary machines are equipped with a powerful asynchronous engine, which provides a cut of thick wood of any species, but in a home workshop you can limit yourself to a lower power.
Note! For sawing boards of medium thickness, it is enough to make a circular table with a drive from the engine of the washing machine with your own hands.
This design has several advantages. The engine from the old washing machine is inexpensive, moreover, such an unit will probably be found in the household of a house. Connecting this engine is not particularly difficult, there is no need to look for a scheme, to solder. With all this, the power of such an unit is enough for most types of work.
The machine diagram can be simplified as much as possible by excluding belt transmission. In this version, the cutting tool will be attached directly to the engine shaft. A frame of a desktop mini-station will serve as a frame assembled from a bar with a cross section of 40 x 40 mm. If desired, it can be welded from the corner or profile pipe.
As a stand (countertops) of the circular, part of the body of the old TV, a coating boat, is ideal. As practice shows, this part is characterized by sufficient strength, and thanks to the lacquer, it does not prevent the glide of the workpiece.
In the countertop, an electric shutter is perpendicular to the cut under the disk, two parallel cuts are made. A mobile square playing the role of lateral emphasis will slide on them. He will help to make a flat cut, if necessary, at a given angle.
Those who plan to seriously engage in woodworking should think about the manufacture of a full.Fledged stationary circular saw. This should be a separate unit installed on a workbench equipped with a powerful engine with the possibility of fast disk replacement. For the manufacture of such a circular will have to spend time, but it will definitely pay for herself.

We mark one end of the side side of the wooden beam of a square section for drilling and rounding of the angles. In the center of the second end, we mark the drilling place of the deaf axial hole, as well as the center of the beam.
In the middle of the beam, on the opposite sides of the Forester drill, we perform the same recesses. The jumper between them is drilled with a smaller drill.
At one end we make a hole with an axis parallel to the axis of drilling in the center. We twist the adjacent corners. At the end on the other side of the beam, we perform a dull axial hole.
We wrap construction tape symmetrically to the center to choose a gap between the hairpin and the holes in the bearings onto the stilettos.
We put the washers at the ends of the studs, tighten the nuts and tighten the keys. So that they do not weaken, wrap them with the second nuts. Then we put on two profile washers for one end of the hairpin and wind up a nut for puffing a disk. In the end of a small wooden block of square section, we plan and drill a deaf axial hole.
We put it at one of the corners of a square carved from wood-fiber plate-panels, and fix it with screws. We orientate the bar with a hole inward. The square of the wood-fiber slab-panels is placed vertically so that the bar is on top. To the bottom of the square from the side of the bar we apply a rectangle of wood-fiber plate-panels with a width equal to the side of the square, and fasten it with screws. A bar with an axis-spille in the center we fasten a rounded end to a short breeze bolt with a puck.
On the second square of wood-fiber plate, we plan a vertical groove, the longitudinal axis of which would always coincide with the center of the hole in the end of the beam when turning around the axis. In a square drill at the ends of the groove marking, we drill the holes and cut it out with a jigsaw.
Outside, we insert a bent hairpin with a pointed end and a barashka nut, which we screw into the hole at the end of the beam with the axis.
Symmetrically the center of the beam below, we fasten the console-straight-fiber plate of the panels, directing it towards a short bar, and securing it with bolts with a semicircular head and spike.
We fix the drill cartridge at the end of the hairpin. We grasp the ring belt on the tool body with a half-smitter, in the holes of the clamp and shelves made of wood-fiber plate panel, insert the screws and tighten it with nuts from the bottom.
On top of vertical elements we lay a rectangle of wood-fiber slab-panels and fasten it outside to the rack with Bar with two mortise door hinges. Throwing back the top panel, we fasten on a hairpin-axis using specialized washers and nuts a saw disk.
Hinge node fastening of the beam to the construction structure
