How To Make A Trimmer Line With Your Own Hands?

The trimmer reel mows the grass. However, it wears out and often requires replacement. Recently, motorcycle or electric scythes have become widespread. The main working element of such a garden tool is a reel with a fishing line tucked inside. Therefore, it is essential to choose a quality element in order not to waste finances because the device is quite expensive. To reduce the cost of maintaining the mowers, you can learn how to refill the forest with a trimmer reel yourself.

Often, manufacturers of mechanized tools do not complete their products with some devices that are necessary or useful for the operation, offering to purchase them separately (as an additional option). The situation with the reel for mowers is different: since this is the main working element of the garden tool, all trimmers are supplied with them, but the quality of the reel from the spit kit leaves much to be desired.
The consumer has to buy the coil separately. this is done to increase sales and obtain additional profit from manufacturers.
Below are questions about what a trimmer is, what reels are, and how to independently insert and secure the fishing line.

What is a trimmer?

Under the trimmer imply tr or electric mowers. It is a type of lawn mower (hand mower) that is designed for mowing grass. It is a modern braid. Initially, they were developed for agricultural work, but the main use of trimmers was lawn mowing.
For the first time the idea to create a trimmer came up with the American entrepreneur J. Bollas. Driving a car through an automatic car wash, he noticed that the principle of rotating brushes could be used for crop mowing.
After that, he collected the first trimmer from a tin can (as a coil) and fishing line, threaded into the holes drilled in it. He installed the received construction on a pole on which the engine from the moped was previously mounted. The device mowed not only wheat but also grass. Realizing that he would earn a lot of money by selling a spit, the entrepreneur improved his product and gave it the name “Weed Shredder”. A feature of the invention was the possibility of mowing the grass around the trees. the forest perfectly cut the grass, but did not injure the bark.

The main purpose of this tool has become grass mowing on small areas in places where the classic wheeled vehicle cannot be used:

  • in the presence of a large number of shrubs;
  • in gardens with lots of trees;
  • near fences and fences;
  • if the plot has uneven terrain.

All trimmers incorporate a bar. the main constructive element. Gasoline or electric motor is attached to the rod from one end, and on the other end, there is a reel with a fishing line. the main working element. In this case, the type of transfer can be any. limited only by the manufacturer’s capabilities and economic parameters.

Why this tool is called differently

Under the “trimmer” it was originally understood as a manual lawn mower with an electric motor. In this case, the power of the mower went both from the mains and from the battery, which can be installed on the rod or carried in a special pouch.

The main cutting element is the fishing line, which creates some restrictions on the type of grass to be treated: only plants with a thin and soft stem can be mowed. The cable length or battery capacity limit the mowing area. Recently, however, spit with petrol engines have also been called trimmers. They give greater mobility to the worker, which allows you to significantly increase the size of the site.

But electric and gasoline braids were originally varieties of lawn mowers, but with the advent of the trimmer, these designs have ceased to be in demand and are now rarely available, and their names have moved to trimmers. for most people it is more common to call this tool.

Coil specificity

In the modern world (both in the city and in the village) it is practically impossible to do without such a modern and useful tool as a trimmer. It is widely used by employees of municipal services of large cities. Such devices are in demand in farms as well. They are used for enriching summer cottages, gardens, gardens, etc.
However, it should be remembered that the main working element is the head for the trimmer. reel with fishing line. This element most often fails and requires care. The price of the coils has a wide range (from 10 to 150 dollars), which makes such a tool even more expensive. Any manufacturer (even brand) completes its product usually inexpensive and low-quality coil. However, you can work for a long time and a first coil, subject to the timely implementation of work to care for it.
Like any other mechanical element, the coil requires cleaning of grass, cooling with overheating and filling the lubricant. However, coils often fail for various reasons, and buying new ones or carrying repairs that have been broken is quite expensive. At the same time, almost all faults can be eliminated independently. Disassemble the coil is not difficult, especially if you use the instructions.
The first part that often fails on the trimmer reel is the fishing line. A fishing line is a consumable item for which the manufacturer is not responsible. At the same time, on many models of coils, the replacement of the fishing line is a complicated procedure (and, for some brands, impossible). An attempt to replace the fishing line with a material other than the parameters of the native fishing line can lead to the destruction of the reel.
The coil itself (the part of the element on which the line is being wound) rarely fails, whereas the grooves through which the working part of the fishing line is passed and which hold it can break (stitch) since almost always they are made of plastic.
Despite the abundance of spare parts for trimmers on sale, not every person can afford to buy them; besides, there are often restrictions on available products. For example, manufacturers make “individual” mounts for a trimmer, and a universal coil will not stand on such mount. It often makes it impossible to purchase a suitable reel for the price. Some manufacturers make reels designed for a thin fishing line (up to 3 mm in diameter), which significantly limits the ability of the trimmer. Therefore, there is the option of the self-manufacturing coil.

How to make a coil yourself?

The basis of the self-made coil is a disc made of durable material. It is best to apply for this purpose textolite about 5 mm thick. It is strong enough and reliable. The size of the disc depends on the dimensions of the trimmer and personal experience. how it is more convenient to work.
Further in the center of the disk should drill a hole. The diameter of the hole must be equal to the diameter of the axis of the rod (the latter is attached to the rotating shaft of the engine). It is essential to determine the center of the disk. After that, you should drill four holes for the fishing line. Their diameter will be equal to the diameter of the fishing line, and they will be placed in pairs on opposite sides of the axis (2 on one side, 2 on the other from the axis of rotation). In this case, the design of the coil is significantly simplified: it is not necessary to wind a large number of fishing lines, but rather to fasten (tie) its small section through the finished holes.
To give the structure the desired strength and reliability, it is recommended to find a spring whose inner diameter will be equal to the diameter of the shaft and install it on the shaft over the finished disc.
After the fishing line is filled and secured to the disk, you can proceed to the tests. The line can not be fixed to the disk still: even if threaded through the holes, it will not fall out, because the engine gives high revs to the shaft, and centrifugal force is sufficient to hold the line under load.
Such a design instead of a purchased reel for a trimmer has many advantages: you can install any fishing line in it (both thin and thick), the device itself is practically “unkillable”, and it will not take very long to acquire a new reel.

The disadvantages of this homemade include the following:

  • the need to cut a pair of pieces of fishing line of the same length;
  • When installing without attaching a fishing line, you must make sure that equal lengths of fishing line hanging from the reel.

The case can be used from the old coil. it rarely breaks.


Such a homemade coil can significantly reduce the cost of operating the trimmer, which improves the parameters of its work. You can use the same trimmer for beveling both small shrubs and soft and thin lawn grass.
