For safety reasons, it is recommended to make a protective device for the device. The casing for the angle grinder is made of aluminum sheet or thin sheet metal.
There are many other units from which you can make a grass trimmer. As a basis, use a vacuum cleaner, drill or chainsaw.
From the vacuum cleaner
In the manufacture of a homemade trimmer from the engine of a vacuum cleaner, 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 fishing line. The engine is also covered with a casing, this will protect it from dust and dirt. To create additional cooling, you need to install a cooling device. It is made of a disk with curved blades (fan) and mounted under the washer through which the fishing line for the trimmer passes. Inward air enters through the hose from above and cools the engine.
From the 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, therefore, a protective cover is attached to the drill.
It is made of plastic pipe and put on the tool body.
Since the engine of the chainsaw is heavy, you cannot make a trimmer with a lower drive from it, but you can make a lawn mower on wheels. Manufacturing process:
- First, a cart is made from a corner of 25 × 25 mm. Its dimensions are 500 × 600 mm.
- At the corners of the structure, wheels are installed.
- The gas cable and fuel hose lengthen.
- The tire and steering wheel are unscrewed. From the water pipe make a handle on which the helm is mounted.
- When installing the engine on the frame, the shaft should be located at the bottom of the structure. In this case, the gearbox is rotated at 90 ° C.
- Then, the cutting unit is mounted on the tool shaft.
