There are many other units out of which you can make a grass trimmer. Use a vacuum cleaner, drill or chainsaw as a basis.

From a drill

If you need to quickly make a trimmer, then a drill will help. To do this, a knife is made from a metal plate and sharpened. Then a hole is made in the center, a bolt is inserted and fixed with a nut. The finished knife is inserted into the drill chuck and gently clamped.

This design is dangerous for the user, so a protective cover is attached to the drill. It is made from a plastic pipe and put on the body of the instrument.

How to make a trimmer from an angle grinder and second electrical appliances with your own hands: drawing,

Any home plot needs mowing of grass. An electric or gasoline trimmer is expensive and NOT every owner can afford to buy one. Therefore, some craftsmen have learned how to independently make a trimmer from an angle grinder.

Trimmer from angle grinder

Consider how to make a trimmer from an angle grinder with your own hands, the order of work:

  • The brace is prepared first. It is designed to grip the body of an angle grinder. The metal plate is applied to the body and bent.
  • There are threaded holes on both sides of the case, in which the rocker handle is attached. Attach a trimmer bracket to them.
  • Holes are drilled in the bracket on both sides in such a way that they correspond to the openings on the tool body. For accuracy, they make notes on the part with a marker, clamp it with pressures and drill.
  • Then a guide is attached to the bracket. Its size should correspond to the length of the body or be slightly shorter. The guide is attached with a welding machine, the remaining scale is knocked down. The part is grinded with a metal brush.
  • A handle (rod) is made from a metal pipe. To fix the handle at a slope, the end of the pipe is cut to be beveled. The finished handle is welded to the structure, the scale is knocked down and the part is cleaned with a brush.
  • To attach the tool, you need to unscrew the protective disc of the angle grinder.
  • Then the homemade product is installed on the wheels. To do this, you can borrow wheels from a trolley or stroller with brackets.
  • First, the angle grinder is mounted, then the wheel with the bracket. All are secured with a bolt. On the other hand, they make the same fasteners.
  • The cutting unit is made from a steel cable. A nylon wire designed for trimmers will do. It is threaded through the Clamping Nut and the key hole using a criss-cross method. Then the nut is tightened together with the cables.
  • The wire is fixed with electrical tape.

For safety reasons, it is recommended to make a protective device for the device. The casing for angle grinder is made of aluminum sheet or fine stiffener.

From a vacuum cleaner

When making a homemade trimmer from a vacuum cleaner engine, the latter is mounted on a bar. The knives are mounted on the motor shaft and covered with a protective cover. Instead of knives, you can use a metal disc with a line. The engine is also covered with a shroud to protect it from dust and dirt. To create additional cooling, a cooling device must be installed. It is made from a disc with curved blades (fan) and mounted under a washer through which the trimmer line passes. Air enters from above through a hose and cools the engine.

How to make a Corn Grinder from an angle grinder

The process of making a homemade grain grinding device should begin with preparing a pan for attaching to an angle grinder body. For this, a Landing Hole is drilled in the center of the bottom of the pan. After that, 2 furniture corners are fixed to the angle grinder using suitable bolts. Do not drill through the tool body. It already has suitable female threaded holes for attaching the handle of the angle grinder.

Completed the indicated operations, it is necessary to accurately measure 4 points of attachment of the pan to the corner. In THESE places, holes of the appropriate diameter are drilled. After that, you can mount the pan in the place of the standard installation of the protective cover of the angle grinder and, using bolted connections, ensure the fixed attachment of the dishes to the corner. In fact, at this stage, the manufacture of a hopper for filling grain can be considered ready.

The second step is to make a chopping knife. To do this, a workpiece of the required dimensions is made from a prepared metal plate using a metal cutting wheel. A landing hole is made in the center of it. With the help of emery, the metal plates of the knife are sharpened on one side, which must correspond to the direction of rotation of the angle grinder.

Then the device is ready for use. The grain is poured into a saucepan and covered with a lid. Due to the revolutions of the angle grinder, high-quality grinding of the grain occurs. The resulting compound feed is poured into a previously prepared container or bag. The process is repeated like a coffee grinder.

How to make a trimmer from an angle grinder and second electrical appliances with your own hands

Any home plot needs mowing of grass. An electric or gasoline trimmer is expensive and NOT every owner can afford to buy one. Therefore, some craftsmen have learned how to independently make a trimmer from an angle grinder.

The main units of the garden shredder

To independently assemble a grass and branch shredder (shredder) at home, you must first understand the mechanism of the mechanism, as well as the principle of its operation. This will help to properly assemble the equipment and, if necessary, make changes to its design.

A home-made unit designed for chopping mowed grass and sawn branches up to several centimeters thick has the following main structural units:

  • Engine;
  • Knives mounted on the working shaft;
  • Frame (usually metal)
  • Protective cover;
  • A box designed to receive cut vegetation;
  • Launch system.

The technique itself can be done in a stationary or mobile form. To create the latter option, you will additionally need wheels, as well as a handle. To make a frame, they use metal corners or ready-made frames from workbenches. Boxes for recycled vegetation are made of plastic buckets, gestures, bags. The protective sheath around the knives must be thick and strong enough not to wear out quickly from the action of the milled vegetation.

The work of the shredder is that the rotation from the motor shaft is transmitted directly to the blades or through a chain / belt drive. The vegetation chopped up by the blades enters the box. In this case, the final product is immediately ready for use.

According to the principle of operation, some home-made shredders are comparable to a grinder (they pull in and then grind organic matter), and others with a coffee grinder.

Grain crusher from angle grinder

If you are doing household chores and you have to prepare animal feed all the time, then a home-made Grain Crusher from an angle grinder, made by hand, will come in handy.

To make a homemade grain grinder, you will need the following materials:

  • Thin sheet metal for the manufacture of a case with a sieve and a receiver for grain;
  • Plywood for cutting the base for the grain crusher;
  • Steel for the manufacture of knives or their ready-made options from a vegetable cutter.

So, let’s start with the most interesting, with making the base. To do this, you will have to take a rectangular piece of plywood, measuring 50 by 40 cm.Near the edge, you will need to attach an angle grinder and trace its contours to cut a hole in the plywood. Subsequently, the angle grinder will be fixed directly into the hole by means of metal bolts and a plate.

Then you can take up the manufacture of the case in which the grain will be ground. It is best done with subtle gestures. After making the case, a lot of holes should be drilled in the bottom, no more than 3 mm in diameter. Through the holes, as in a well-fed, grain crushed by knives will pass grain.

Knives, as mentioned above, are best made from a strip of thin steel. For the convenience of fastening, the knife can be fixed directly with a nut from an angle grinder, having made a hole in it previously suitable for the diameter of the rod. Now it remains to make a receiver for filling grain in the Grain Crusher. You can also make it from gestures or from a 5 liter plastic bottle with a cut off bottom.

Chainsaw mower Do-it-yourself friendship

To get quality and durable equipment for mowing grass, you need to strictly adhere to the correct algorithm of actions. A standard self-propelled lawnmower is assembled in the following order:

  • First, the pipe must be inserted into the groove of the bearing used, and also the gear must be fixedly placed inside;
  • By the end, which remained free, it is necessary to weld 2-centimeter “ears”. After that, holes need to be drilled in the “ears”;
  • To make knives, you will need to cut the blade from a hacksaw. It must be cut into several equal parts;
  • Rivets must be used to secure the knives to the rotor disc or to the prepared bar. The diameter of the finished structure should be about 40 cm;
  • After that, you will need to weld a rigid frame using a metal corner for this. The frame should be reinforced with steel struts, which will prevent it from breaking when the mower hits a tree or bench. Base frame dimensions Must match the dimensions of the chainsaw;
  • Inside the frame, you need to install a rectangular stand. the mower body will rest on it. To make the equipment as balanced as possible, all its connections must be placed strictly at right angles and be sufficiently rigid;
  • To the finished frame, you need to weld fasteners, which will help fix the wheels, handles and individual metal hooks, required to support the entire device;
  • After that, you need to install the wheels;
  • Next, you need to fix the chainsaw, having removed the headset from it in advance. The tool must be rigidly fixed to the frame;
  • Then, along the contour of the finished case, you will need to cut a steel plate. It must be installed above the chainsaw. The result is a reliable metal casing that protects dust from moisture and grass;
  • At the next stage, the manufacturer should screw a pipe with cutting knives with a homemade mower to the chain saw drive sprocket;
  • At the end, it remains to install the handles on which you need to take out the levers and control buttons of the lawn mower.

According to this scheme, not only a rotary lawn mower is manufactured, but also a segment-finger or flail lawn mower. The difference between them lies only in the device and the principle of action of the cutting body.

Varieties of engines for assembling homemade products

Electric and gasoline engines taken from unused equipment are used as a drive for homemade products. Each of THESE two options has its own advantages and disadvantages. Models with an internal combustion engine are more convenient in that their operation does not require a nearby power supply. But in general, they are more expensive and have a more complex structure than their counterparts equipped with an electric motor. Therefore, it is easier to make electrical equipment, in addition more compact.

The maximum thickness of the cut branches, which the shredder can grind, depends on the power of the electric motor installed on it and the characteristics of the knives.

  • Models with a motor up to 1.5 kW are capable of grinding sticks up to 20 mm in diameter. They are designed for low intensity work.
  • If an electric motor from 3 to 4 kW is installed, then such units can chop branches already up to 40 mm thick.
  • powerful electric motors (over 4 kW) are used to make a shredder for wood with a diameter of 7-15 cm.

To create a homemade shredder, you can use an electric motor from an angle grinder, washing machine, trimmer. They must be adapted to work from a stationary network with a voltage of 220 V. In order to grind material of the greatest possible thickness at home, it is recommended to equip the shredder with an electric motor for 1500 rpm with a power of about 3.5 kW. This parameter in internal combustion engines corresponds to 5-6 horsepower.
