What are the main features to keep in mind when buying a grass trimmer?
The main difference is the operation of the grass trimmer with water or dry.
Work with water, or “wet” trimmer requires in addition to the electrical outlet, connection to the water mains and, consequently, the presence of a drain line.
To understand which grass trimmer to choose, you need to determine what kind of gypsum you usually work with and what discs you use for it.
Carborundum discs are good for normal, soft gypsum. If the gypsum is very hard, you should choose discs with a spot or full coating of diamond.
Carborundum and all-diamond blades need to work with water, because of the possibility of clogging of the blade coating with gypsum. Discs with a partial or dot coating of diamond chips do not require water for work.
Important parameter for discs, especially for carborundum is balancing, which affects disc runout, noise characteristics of the grass trimmer and durability of the electric motor bearings.
Some manufacturers use quick-release carborundum discs such as “Klettfix” (Renfert). The replacement disc looks like a disc cut out of waterproof sandpaper. On one side there is a carborundum layer, and on the other side there is ordinary Velcro. Changing the disc takes seconds. These discs are available in different roughness, and a quick change is convenient when processing plaster of different grades.
There are many other units, from which you can make a grass trimmer for grass. Use a vacuum cleaner, a drill or a chainsaw as the base.
From a vacuum cleaner
In the manufacture of homemade grass trimmer from a vacuum cleaner motor, the latter is mounted on a boom. The knives are installed on the motor shaft and covered with a protective cover. A metal disk with a fishing line can be used instead of blades. The engine is also covered with a hood to protect it from dust and dirt. To create additional cooling, you need to install a cooling device. It is made from a disk with curved blades (fan) and mount it under the washer, through which the line for the grass trimmer trimmer. Air enters from above through the hose and cools the engine.
From the drill
If you need to quickly make a trimmer for the grass, the drill will help in this. For this make a knife from a metal plate and sharpen it. Then a hole is made in the center, a bolt is inserted and secured with a nut. The finished knife is inserted into the drill chuck and gently clamped.
Such a design is dangerous for the user, so the drill is attached a protective cover. It is made from a plastic tube and put on the tool body.
From a chainsaw
Since the chainsaw engine is heavy, you can not make a grass trimmer with a lower drive, but you can make a lawn mower on wheels. Manufacturing process:
- First, from an angle of 25 × 25 mm make a cart. Its dimensions. 500×600 mm.
- At the corners of the structure set the wheels.
- The gas cable and the fuel hose are extended.
- The tire and the hand wheel are unscrewed. From a water pipe make a handle on which to mount the hand wheel.
- When installing the motor on the frame, the shaft must be located at the bottom of the structure. The gearbox is at a 90° angle.
- Then the cutting assembly is mounted on the tool shaft.
The tool is ready. To make it easier to work with, you can buy a shoulder or backpack strap for the grass trimmer in a store.

From a safety standpoint, the hacksaw blades should not be completely glazed.
All you need for making the attachment
The most difficult thing in the manufacture of the nozzle is to symmetrically mark and make holes for the blades and shaft of the grass trimmer. That’s why a ready-made peorized plate is chosen.
First you have to make the base of the trimmer. For this purpose from a metal plate by the angular grinder cut out a square with the side of 100 mm. Mark it so that exactly in the center (at the intersection of the diagonals) there is a hole. For this purpose from the center of the chosen aperture perpendicularly to the short side of a plate we measure off distance of 50 mm and we mark lines of trimming.
We cut off unnecessary things and get a square of 100 mm x 100 mm. Now you need to round the corners a bit and drill a center hole for the grass trimmer shaft.
To round corners and drill a central hole for the shaft of the grass trimmer

The metal blade is cut, measuring from each end 8 cm. We obtain four blanks with completed holes.
These blanks are to be shaped into blades. To do this, we mark the line for the trimmer cut by eye (no special accuracy is required), fasten all four workpieces together and grind off the excess.

- Then you need to make a marking for the fasteners. As a base, which will be screwed home-made protection, you can use the standard cover from the angle grinder if you make a trimmer for the grass out of it.
- Clamp the workpiece with a clamp and, using a tape measure and a pencil, draw the first circle with a radius of about 270 mm. The corner of the workpiece will serve as the center of the circle. It is impossible to give exact recommendations about the radius, because it will depend on the diameter of the cutting tool you will use with the machine. Therefore first decide what kind of blades you will use, and what kind of line reach will be optimal.
- Next, draw a second arc (it will be a bend), a little back from the first. In this case by 5 centimeters. This is how you will measure the height of the future board. In general, it is recommended to make the height of the cover so that when you put it flat on the ground, the cutting tool will not reach it about 2 cm.
- After marking the second line necessary to cut along it the workpiece, using a jigsaw for metal or jigsaw with a file on metal.
- In addition, you need to make radial cuts (up to the first arc) and bend the resulting parts with pliers at an angle of 90 °.

Grass trimmer from angle grinder. Instructions and diagram with explanations
Grass trimmer from an angle grinder. At any moment the angle grinder easily turns into a mower. and vice versa.For the mower you need to add an extension cord or a soft double wire with a cross section of 2.5, the socket. switch and plug. Cut the wire from the socket side of 30 cm and insert the switch (preferably from a drill. angle grinder of the same power) In my case, I will not use an angle grinder. That’s why I took away a part of the angle grinder body with a button. to reduce the size.
The main thing is to close all cooling holes. I glued them with duct tape and the body. part of a plastic bottle.
Since the ventilation is closed, it is necessary not to overload.
All parts of the mower are assembled from improvised means. Body and handle was taken from the heating tube 15. fixing with an angle grinder 2 to 3 mm steel plate. bent at an angle of 90 gr., and welded to the pipe at an angle of 45gr. Handle (angle tube) 90gr. It is fastened to the body with a bolt, M10 thread, and can be adjusted for height. the belt clings to it. All sizes are shown in the photo mounts for angle grinder with a disk 180. Therefore, the holes for bolts must be adjusted to the size of the body of the angle grinder. The switch is moved to the edge of the case, adding 1.5m. copper wire 2.5 mesh., and fastened with insulated tape (inserted into the tube from a bicycle)
The most important and the most difficult part in my case. This is a fishing line mount. It took me several months of testing different versions of mounts. to get the results I wanted. The mount is made of two old diamond discs for stone. cut out the disc core with the angle grinder as on the photo.
Grind more corners then put the core of the disk on a grinder. and do not put much pressure, grind against an emery stone to a circle f90mm. 2 pcs.Mark the diameter at 50mm. On one and bore holes as on a photo.Holes 4.5 and 3.5 are for line of 4 and 3 diameters. You can drill and 2.5 for a line of 2.5. Fixing the line for the trimmer as shown in the photo. trimmer line 18cm. insert into the holes and bend.
Long edge of line should be between the two blades. If the weed is small and the turnover is young, the line should be tightened.
I added a speed regulator, the mowing is much better. If there is little grass and young grass, I turn down the speed so as not to strain the engine.
I also removed the line fastening that I described in the beginning. I fixed the discs to the standard factory settings, and used them to clamp the line to the trimmer
(only the line for the trimmer ti now must be thick, I have 4 mm), otherwise it will curl.
