Making with your own hands a stationary machine from a hand-held circular saw
There are situations when there is a handheld circular saw, and to perform the work you need a stationary design, which is caused by the need to process long workpieces or a large amount of the same type of operations performed. In this case, you can independently make a table on which to place the existing electric hand tools, and then use it as a permanently installed equipment. All work can be divided into several stages: preparation, manufacture and assembly, and testing.
At this stage of the production work prepare the material from which the work surface (table) of the manufactured machine tool will be made, as well as its base, develop a sketch. Hand circular saw is prepared, as well as other elements: wires and cables, a button or automatic switch on the circular saw in operation.
Fabrication and installation
Once the tools and materials are prepared, as well as a drawing (sketch) of the assembled structure, you can begin to make it.
The sequence of manufacturing from wood and plywood is shown in the following table.
|Using thick plywood 12-15 mm thick, the circular saw table is made according to the developed drawing. Holes are drilled in the side wall to allow air circulation inside the table.
|On the table top you cut a hole to fit the circular saw blade according to its geometrical dimensions. It is installed.
|Tabletop is fastened to the table with the help of door hinges, which allows to move it horizontally.
|To fix the circular saw, the fastening elements are used, which allow to dismantle the construction if necessary.
|An electric socket is mounted inside the table body, and the wires are fixed with mounting clamps.
|On the outer wall of the table an electric switch is set, which provides operation of the assembled construction.
This design can be mounted separately or placed on any horizontal surface. Its geometry depends on the size of the hand-held tool and the needs of the user.
When the construction is assembled, it should be tested in operation, for which it is connected to the power grid, corresponding to the voltage class of the used circular saw. When serviceability is checked, the finished product can be supplemented with the necessary tooling elements (stops, clamps, etc.).д.) and accessories to make it easy to use during the work.
Miniature machine from a washing machine motor
The circular saw is characterized by extreme simplicity and availability of materials for its manufacture. Perhaps the only expensive part is the electric motor. Stationary machines are equipped with a powerful asynchronous motor, which provides the cutting of thick wood of any species, but in the home workshop can be limited to a smaller capacity.
Please note! For sawing boards of average thickness is enough to make their own hands circular table with the drive from the motor washing machine.
This design has several advantages. The engine from an old washing machine is inexpensive; moreover, such a machine is likely to be found in a household household handyman. Connecting the motor is not particularly difficult, there is no need to search for schemes, to engage in soldering. With all that, the power of such a machine is quite enough for most jobs.
The scheme of the machine can be simplified as much as possible, eliminating the belt drive. In this variant the cutting tool will be attached directly to the motor shaft. The base of the table mini machine is a frame made of 40 x 40 mm bar. If desired, it can be welded from a corner or shaped tube.
As a stand (tabletop) of the circular saw, a part of an old TV body will be ideal, Woodchip board with a coated. As practice shows, this part is sufficiently durable, and thanks to the lacquer coating does not prevent the sliding of the workpiece.
In the table top with an electric jigsaw perpendicular to the notch under the disk make two parallel cuts. The sliding angle, which plays the role of a side stop, will slide along it. It helps to make a straight cut, if necessary, at a given angle.
A sawing table with my own hands from a hand circular saw
Homemade sawing table with their own hands, photo and detailed description is attached.
Here I decided to make a cheap and practical sawing table from a hand circular saw. Bought laminated chipboard (yes, such things are not correct to do from chipboard, but, realistically, I have not found moisture-resistant plywood, and admittedly, in Minsk, I’ve never seen it in the eyes). I took two pieces of 600 x 800 x 16 mm and 300 x 800 x 16 mm. Bought aluminum angle bar 20 x 40 x 2000 mm and channel 10 x 10 x 2000 mm. Got 40 screws, two metal rulers for 500 mm.
Got to work. The base plate will be 600 x 800 mm. Slab 300 x 800 mm, cut into 50 x 800 mm slats. I used them to make a edging which added stiffness. Assembled everything with Kleiberit PUR 501.
I milled a cavity for the channel and glued it with Soudal Fix All Classic. Too bad the channel is a 10not a 15well, what do I haveI’ll find it, maybe I’ll redo it. Then I milled tracks for the ruler.
I cut the rulers to size, precisely positioned them on the disk and glued them to the Soudal strip in the same way.
Then I took the parallel stop. I didn’t want to squeeze the stick scraps with clamps every time, so I decided to do it on the factory sawing machines. The basis of the aluminum angle 20 x 40 mm. It has not much stiffness, so I reinforced it with a wooden bar, gluing them together. I riveted a 20mm x 20mm corner to the back of the guide. This will allow positioning the stop perpendicular to the table. And I decided to make a fuss with the fastener. To realize the idea, I needed a piece of aluminum.
Where to get a piece of aluminum? Sawed off from the disk.
I took the clamp, which I didn’t need I borrowed the parts I needed from it.
Parallel stop was joined to the clip with two bolts with anaerobic glue.
It turned out very convenient not much worse than factory quick release stops. Then there are the little things the installation of electrical outlets, wiring, the switch. The button in the saw is locked in place.
All this works in conjunction with a vacuum cleaner with an autopower. I forgot to take a picture of the broach carriage but it’s pretty clear. The circular saw is now based on a 160th disk it’s not enough of course. The thickness of the kerf is now 37 mm.
I’ll probably buy and install another circular saw in a monthbased on a 210 or 235 disk. It is obligatory to have a circular saw with a wedging knife. If I put a circular saw with a 210-235 blade, then I will definitely put together a soft start module for the saw.
Of course, such a sawing table from a manual circular saw is an economical optionthe need makes. And it does not fully replace the factory productespecially when it comes to sawing at angles. My table has two positions90 and 45 degrees. As a rule it is enough. Excluding the circular saw, which was in the farmthe cost of all materials (without glue) was 30even with the saw on a 235-disc, the cost of such a machine would not exceed 160which is exactly half the cost, a factory table like Bosch or Makita.
How to make a machine tool for a circular saw with my own hands? First of all you need to choose materials.
The key requirement for a table top is considered resistance to increased loads, vibrations and shocks. It is important that the surface is sufficiently smooth and will not bend under the weight of 50 kg. The optimal materials include the following:
Do not make the table top of plastic, chipboard, OSB. Such raw materials are not considered to be resistant to vibration. Using natural wood is acceptable. But in this case it would be very expensive.
On the base of the table you can install wooden planks. It is recommended to fix them under the lid in order to increase the rigidity. It is best to use planks made of hard wood like beech or oak. They are inexpensive and easy to install with self-tapping screws.
It is advised to use a motor of no more than 1000-1200 W. Otherwise the use of the device can be dangerous. In addition, a heavy and sturdy table is needed for the power saw.
Transmission of rotation
Belt drive is permissible for the construction. In this case, the drive is transmitted to the work shaft by means of a V-belt. The pulleys on the machine can be matched in size. Therefore, the speed of the working shaft will be the same as that of the motor.
How to make a stationary circular saw from a cutting saw with his own hands
Dear visitors site samodelkin a friend today we will consider a detailed step by step instructions on how to re-equip the circular saw in a stationary circular with their own hands. Every craftsman knows how good it is to have your own stationary circular saw, with which you can cut boards of different widths, saw grooves and all this is quite convenient. But not everyone who likes to do carpentry can afford to buy a factory machine, and if you work from time to time, it does not make sense to spend money to buy. But it is quite possible to make a circular saw from a cut-off saw and a few sheets of plywood or particle board. Saving strength, time and family budget)
To assemble a home-made stationary circular saw, you will need a cut-off circular saw, some self-tapping wood screws with a press washer, thick plywood or chipboard, an electric extender and some more self-tapping screws to assemble the table itself.
- electric circular saw
- Self-tapping screws with washers
- plywood or particle board
- the electric cord holder
- wooden saw
- clamping clamp 2 pcs
Step-by-step instructions for making a stationary circular saw with your own hands. To begin with, a board under the tabletop of the machine was cut, then a marking was made for sawing. Drill at least 4 holes in the cut-off saw base for securing it to the bottom of the table. Marking for cutting area. Self-tapping screws for securing saw to table top. Screwdriver screwdriver screws, by the way their length should be shorter than the thickness of the board to which they will be screwed. Making the cut with the circular saw along the planned line. We set and check what will be the height? Then the table itself is going to be assembled, the dimensions are chosen individually depending on your physiological peculiarities. Connect to the electric cord with a switch (red button) the guide rail can be made from a wooden lath, fixing it at the edges of the screw clamps. Test sawing. Everything is fine) This is how you can make your own stationary circular saw. Thank you for your attention!
Advantages of homemade equipment
Homemade circular saw is considered a fairly popular tool. Easy to make and highly reliable.
So, the circular saw with their own hands has such advantages:
Today you can find many drawings that allow the construction of stationary or mobile saws of different sizes. For this you can use a drill, angle grinder and other tools.
Some masters combine a circular saw with a jointer, placing them on one base. These devices can operate from a common motor. It achieves a perfect deburring of the wooden surface. That is why a combination of fillet planer and circular saw is a very functional solution.
If the craftsman plans to engage in professional woodworking, you should take care in advance about the construction of a stationary machine. Before converting a manual circular saw into a stationary saw, it is worth creating a drawing of the unit, allowing you to choose the optimal configuration of the device.
The base frame is the base of the machine. It must be stable and strong. It makes sense to make the base out of metal.
It is best to use profile pipes or thick-walled angles.
For your information! If you want to make a folding frame, bolt it down, not weld it.
Turn Any Circular Saw Into A Track Saw!
The table top should also be made of metal. For this, steel or aluminum-based alloys can be used. The tabletop must be smooth and resistant to friction. It must be strong and not sag under the weight of 40-50 kg.
A slot must be made in the tabletop for the disc outlet. To do this, the craftsman must make a cut in the sheet metal.
Depending on what drive will be used, you need to select the motor for the circular saw. In the case of small discs, whose diameter does not exceed 170 mm, it is worth buying electric motors with a power of 0.5 kW. For larger discs it is worth using a motor more than 1 kW.
Conveying of rotation
V-belt drive can be considered as an optimal drive for the circular saw. One pulley will be on the motor and the other in the area of the drive shaft. Due to the fact that there is no direct connection between the motor rotor and the disc, in a situation where the belt slips, the power to the unit will be turned off.
The use of friction wheels with chutes of different diameters allows the master to regulate the speed of the machine. The rotation from the rotor of the motor will be transmitted to the shaft.
How to make a circular saw?
As with the invention of the bicycle, there is no unambiguous answer here, in each individual case it is its own untrodden path of search and discovery.
But, basically, on the question of how to make a circular saw, masters attempt in several directions:
- improvement of existing hand tools, adapting them as the main parts. the electric motor and the circular saw;
- Improvement of industrially produced tools for specific applications;
- assembling a machine from separate elements. shaft, motor, bed;
- self-made all parts of the construction, well, except for the electric motor.
Manual construction of the circular saw
The easiest and relatively inexpensive way to make a stationary machine for sawing wood with a circular saw will be to convert a manual circular saw into a stationary. The essence of modification consists in creation for industrial model of the stationary frame and the working table.
Such modification will allow to attach the saw to the tool bed upwards, fix it on the work table, and thus use it as a small circular saw. The guide for cutting slats is made of 25×25 mm steel angle, it is attached to the work table.
Sama frame welded from 25×25 mm angles, given that the largest standard size of a circular saw is 230 mm, such a frame is enough to create a lightweight, portable but stationary saw, whose main application is small works that do not require a long motor voltage.
Such a variant of use is implemented in some models of domestic and foreign manufacturers of power tools, in which any solid surface is used as the base of the machine, and the assembly saw itself is attached to the base with the help of clamps.
Desk small circular saw
This option provides for the manufacture of the machine body from wood or iron angle or profile pipe, taking into account that the placement of the tool will be in the table version. Since the base will be small, the use of such a tool opens up new possibilities. Such a woodworking machine allows you to carry out work in any convenient place.
The principle of creating such a machine is similar to how a hand-held circular saw is created. for the base, the body, the top plate, the device for fixing the assembly saw or angle grinder, in the case of using an angle grinder as a motor is made.
For the convenience of work, it is recommended to make the guide plate with guides to fix the stop in the base housing, thus increasing the reliability of attachment. For clamping here it is recommended to use bolts with wing-nuts, thus creating additional convenience in the work.
Circular saw from an angle grinder
This option of making the machine is more popular, as a rare owner who likes to do everything with their own hands, does not have, or in the near future is not going to buy, an angle grinder. The first of the stages of making a stationary saw unit is also to make a special table to attach the angle grinder.
In this case, the process becomes more complicated, as the main difficulty is to think about how to attach the angle grinder to the bed: how to make a sliding stop and axial handle. However, there is a ready-made method that allows you to get a reliable connection.
- For the manufacture of a sliding stop take two pieces of steel angle. They are fastened on both sides of the saw blade. Then they are connected by a cross tie (bolts and nuts). To ensure the necessary gap, washers are used.
- Preliminarily a metal band clamp is stretched on the tool, the screw tie of it should be at the bottom. Attach a metal strip, folded in half, to the holes designed for the sliding stop.
- In the gearbox of the angle grinder, several holes are made for the bolts: first the body is disassembled, then the points for drilling are marked. They will be used to fasten the axial handle. This element is made from a bar or metal pipe. The handles are shaped like a staple. Drill holes at the ends, at the points of attachment to the gearbox.
- Make a rod to adjust cutting depth. It is made from a piece of metal bar. Form a hinge on one side, then rivet it slightly, drill a hole designed for the thrust bolt. On the other end, the thread is cut and the first nut is tightened, and after the construction is assembled, the second nut is screwed on. The depth of cut is adjusted by tightening or loosening them.
Not too complicated actions will make it possible to obtain a full-fledged circular machine for cutting various materials. Do the same with the drill, which can to some extent replace the angle grinder. To avoid potential mistakes, it is better to use the drawings, which can be found on the Internet if you want.
