How to make a screw yourself: step-by-step instructions with photos

“A snow blower is an indispensable thing in winter” - every private owner will confirm this. It will clear the area of ​​snow and ice several times faster and more efficiently. In this case, the user will need to exert much less effort than when using manual equipment.

There are many types of snow blowers according to different characteristics - cheap, middle class, expensive, professional, wheeled, tracked, self-propelled, non-self-propelled, with a steel auger, with a plastic auger, with different snow scattering distances, electric, gasoline, and so on.

Prices for their types also vary greatly - from 10,000 to 150,000 thousand rubles. Not everyone can afford such an expensive device, so the topic of how to make a snow blower yourself has become popular. The basis is a classic trimmer, preferably a gasoline one, since it is more powerful than an electric one.

If you decide to save money, don’t want to buy, or you have nothing to do, but want to make something, then read on - how to make a snow blower from a grass trimmer.

First we need to say that not every trimmer will work. The main reasons are power and shaft. If you have an electric trimmer, then most likely it will not work. Electric models are less powerful, making it harder for homemade snowblowers to clear the area. They will not be able to do anything with ice or if there is a lot of snow, plus the engine will often overheat. Regarding the shaft, the trimmer rod/tube should be straight and level, with no bends near the nozzle.The fact is that trimmers with such a bend use a flexible shaft - a special cable that transmits torque from the engine to the reel. The cable is not designed for heavy loads, so the motors are installed in them accordingly. If you make a snow blower out of it, then its power will not be enough for even a small amount of snow. The engine will be constantly overloaded, it will overheat and shut down. The cable/shaft may also break.

If you have one of these models, don't even try to make a snow blower out of them.

Preliminary work on creating a homemade snow blower. To make a snow blower from a trimmer, you will need:

• Trimmer
• Tin, thin sheet metal (thickness from 2 millimeters, 1-2 sheets measuring meter by meter)
• The bottom of a metal barrel or cylinder
• Profile pipe (standard thickness, length 2.5 meters)

Tools:

• Spanners
• Welding machine
• Grinder and/or drill with bolts and screws
• Hammer, marker, ruler, tape measure

First of all, prepare all the elements and the workplace. Also at this stage you need to disassemble the trimmer reel - remove the protective casing and the nozzle with fishing line from the reel. They will not be needed, but leave all the fixing elements.

How to make a snowblower from a trimmer. The process of making a homemade snow blower

If you have a beer barrel bottom, this will make the job much easier. If it is not there, take its dimensions as a basis, cut out a circle from thin sheet metal, which will need to be surrounded by a ribbon of the same metal. Its length should be equal to the length of the circle, and its height should be 20-25 cm. Next, make a hole in the center of the circle and weld the elements together.As a result, you should end up with a cylinder without one bottom and with a hole in the second bottom - a drum/working chamber.

Cut two sections of 60 cm long each from the profile pipe - this will be the basis of the structure. Attach them to the made drum, they should fit snugly against each other. Cut a piece from the prepared pipe as long as the distance between the ends of the pipes. Cook it with two other pieces. You've done the groundwork.

Now take care of the support for the trimmer - you will need two sections of the same profile pipe 60 cm long, two smaller ones (their length depends on the angle at which the trimmer will be located, choose it yourself) and a rod (longer than the width of the drum). At one end of each long piece you need to make a hole for the rod. The short sides of small pieces need to be cut off with a grinder. The depth of the cuts also depends on how much you want to tilt the trimmer while working. At this stage, you can try it on by leaning the trimmer on the rod. Choose a suitable slope and weld all the pipes together. As a result, you should have a base with a support that resembles a tilted swing.

Cut a circle from thin sheet metal the same as the one inside your drum, but a few millimeters smaller. In the center of this circle, make a hole for the trimmer coil. Next, cut out the blades from the same sheet. The length of the blades should be less than the radius of the circle. The hole must not be blocked by the blades. The blades can be curved, straight, straight at an angle, rectangular or triangular (right triangle) shape, there can be 5, 6, 7 of them. It all depends on your desire. Weld the finished blades to the circle. The distance between the blades on the circle should be the same.It is recommended to make 6 triangular blades and install them at an angle.

Cut a hole in the drum wall for a snow ejection pipe. Choose the size and diameter of the pipe yourself, based on your situation. Then weld the drum to the base of the structure made of a profile pipe and check how the previously made nozzle fits in it.

Cut an isosceles trapezoid from thin sheet metal. Choose its height yourself in the range of 15-30 cm. The length of the larger base is in the range of 30-46 cm. You will also need two rectangular trapezoids, the length of each of their larger bases should be equal to the length of the side edge of the isosceles. Height 15 cm. You will also need a rectangle as long as the smaller isosceles base and 15 cm high.

Weld these elements together to form a ladle. Place it on the drum. Mark where the rectangle blocks the drum. Cut the rectangle along this line. Weld the ladle with the drum. You can weld a piece of rectangle to the top of the drum so that when the blades crush and throw out the snow, it won’t fall back out.

Thread the trimmer spool into the drum. The drum itself needs to be secured instead of the protective casing, and the blade attachment instead of the attachment with fishing line. A plastic sewer corner of the same size must be placed on the pipe in the drum.

How does a homemade snow blower work? The user pushes the car. Snow is taken into the bucket. The blades rotate from a shaft that rotates the trimmer motor. They crush the snow, after which it flies out through the discharge pipe. A sewer angle is installed on the pipe, which can be rotated to change the direction of snow discharge. The basis of the design allows you not to hold the trimmer in your hands, but to push it like a cart or sled.
