Mini circular saw
We welcome all visitors to our site! More recently, information about some devices, such as home-made machines, etc., has appeared on our Internet resource. Today we will talk about another effective device - the hand-held saw! Such a device is quite mobile, you can work with it in the yard, it allows you to work on cutting sheet material.
Video instruction for the production of a circular saw
This article is intended for those who are interested in how to make a circular saw yourself . Such a saw has the ability to work on a 12V motor, so you can power it from rechargeable batteries. You can take and connect it in your car. The saw is used for cutting boards. The motor you choose should have great power - only in this case the work will be definitely effective.
What materials and tools are needed?
The following materials are used to carry out the work:
- - 12-volt motor;
- - 12 V rechargeable batteries;
- - the switch;
- - cutting disc 110 by 20 mm;
- - adapter for the motor (with which you can install disks);
- - plastic sheet or others;
- - small screws, screws;
- - epoxy adhesive;
- - clamps made of metal;
- - plugs for plastic pipes;
- - two corners of plastic pipes (27) and a piece of pipe (used as a material from which to make a handle);
- - a piece of plastic pipe with which a protective casing is created;
- - a block with contacts;
- - shrink;
- - paint.
There is also a need to use the following tools:
- - hacksaws for metal;
- - glue gun;
- - drills;
- - soldering device;
- - marker;
- - rulers;
- - rivet gun;
- - screwdrivers;
- - Dremel (recommended).
The saw blade is manufactured in the following ten steps.
Installing the cutting disc
Using a special adapter (disk adapter), you must attach the cutting disc to the motor shaft. Today, such an adapter can be easily found in many specialized stores. Securely tighten the screws, install the adapter, and then install the disk: its mounting is made just like it is done on the grinder. The disk should not be unscrewed during operation, therefore, well tighten all available nodes.
Installing the engine on the base
First of all, find some plywood or other durable material through which the base will be made. Cut out the desired piece and draw the appropriate lines. Next, using a clerical knife, you need to cut a window, then drill holes in the material.
Then you can attach a motor with a few clamps, screws with nuts and washers. In order to avoid the "walking" of the motor on the basis, firmly tighten the nuts. Next, you need to make sure that the rotating disk does not touch the base. The base before assembly can, for example, be spray-painted in green. It is necessary to drill holes for the heads of the screws, so that they do not have to be ground.
Making and installing the protective wing
The shaving during the work should not scatter on the sides, therefore for such a device it is necessary to install a protective shield . It is possible to make a protective shield from a plug for plastic pipes of size 110. It is necessary to make measurements and cut off the excess part from the cork by using a metal hacksaw. In addition, cut the groove under the motor shaft.
After the manufacture of the wing can be taken for its establishment. This can be done with aluminum corners, as well as a rivet gun. It is necessary to drill holes of the required diameter and install on the wing rivets, putting the washer on the other side. It is recommended to use rivets for gathering.
Special casing for motor protection
The motor must also be closed, because it must be protected from dust particles, in addition, it can overheat. The casing is made of a piece of plastic pipe of the appropriate diameter. Using a hacksaw for metal, it is necessary to cut along, then fix the casing with corners made of aluminum.The corners are fastened to the casing with rivets, and the casing is fixed to the base with screws and nuts - this is necessary for the possibility of removing the casing and having access to the motor.
Manufacturing a handle
For safe operation of the device, you must have a convenient and reliable handle. You can make it using two connecting angles for pipes and two small pipes. It is necessary to cut everything to the required dimensions at the required angle, then assemble it with glue.
Now you have a handle!
Switch and setting of the handle
Only after installation in the handle of the switch (key type) handle. At installation of the switch it is necessary to take into account Amperage. Cut the switch, install it using hot glue.
The fixation of the fixed handle is made at two points, after which the handle is fixed to the base. Epoxy glue is used to attach the second end to the motor housing. It is good to clean the bonded surfaces with a dremel or emery cloth, and then apply an epoxy. Now your device is "not afraid" of any breakdown, because, even if this happens, then removing the handle with the casing, you can repair everything.
Application of paint
The product must be painted (for example, with a can) because this will give it additional respectability. At the same time it is necessary to glue the switch and other non-painting elements with adhesive tape.
The rear cover is made using a cap for plastic pipes of 60 mm diameter, it is necessary to cut off all unnecessary from it and try . With the help of the plug, also installed in this part, the device will be connected to the power supply. It is necessary to cut a hole under the shoe.
Next, you can proceed to the assembly, first of all, you need to output the supply wires. We solder one wire directly to the contact of the motor, and the other into the gap through the switch. Wire ends should be removed through the back cover and heat shrinkable. Next, you need to solder the connector, then fasten it to the cover. /medium/1518496221_70.jpg "style =" max-width: 100%; " alt="Mini Saw">
After this, we fix the back cover, and grind the screw caps on the working surface with a "Dremel" or sandpaper. The machine is ready, it's time to test!
Properly determining the polarity can be called the most important step in the process of connecting the saw to the power source. From the success of this moment depends on whether the rotation of the saw in the direction in which you want. Testing is carried out by an experimental method! In order to be able to take a saw with you to any place (for example, to a forest), 12 V batteries are used. It will be more appropriate for prolonged use in the workshop to connect the saw through the power supply, but we must not forget that the current must be necessarily straight! Good inventions to you!
