Makeshift brush cutter attachment for chain saw
Simple bush cutter attachment for chainsaw: photo and description of making a homemade.
This device will greatly facilitate the process of cutting down various shrubs and bushes on the garden plot. Remove such overgrowth with a manual hacksaw is tedious and unproductive, chopping with an axe is not easier and also ineffective. Even the best chainsaw will not help: thin and flexible stems will slip off the saw chain, almost no damage. You can get out of the situation, if you equip the chainsaw with a device that will not allow the stems of bushes and young trees to slip off the saw chain. Then you can quickly and easily clear the area of spontaneously overgrown bushes and trees.
Materials for making:
The photo shows a homemade attachment gasoline cutter for chain saw.
The following shows the process of making a homemade machine.
First, the master took the chainsaw, unscrewed the nuts and removed the chain guard. Then he removed the chain and guide bar. Removed the circlip and freed the drive sprocket.
Then I put some drops of used oil on the sprocket with a cotton swab. He took the washer and put it on the sprocket, with dots of oil on it. Using that, the author drilled the holes while holding the washer in a vise.
Then, without taking the washer out of the vice, the craftsman carved a hole inside the washer in the shape of the drive sprocket on the tool.
All cut edges were machined with a file.
picked up a washer with a suitable hole, put it around the sprocket on the chainsaw, then put the previously prepared washer with the cut out shaped hole on top. After trying it on, he placed a bicycle sprocket on top, and then welded the parts. Cleaned up the welding seam.
Then the craftsman, took a rectangle of sheet steel. Marks it as follows, on one short side marks the center and from it draws the marks and draws lines on them.
Then he clamped the part in the vice, drilled the hole by the mark and cut out the surplus according to the lines. Having repositioned the part in a vice on the edge, the author refinished the cuts with a file. Under the groove, he drilled a hole. I fastened the ready plate to the saw, as shown on the photo.
To do this he needed two bearings, two identical pieces of round tubes (one with the diameter of the outer ring of the bearings, the other with the diameter of the inner ring of the bearings), as well as a long bolt, which should fit tightly into the tube with a smaller diameter.
The author first pressed the bearings on the ends of the large pipe. For this he used a vise. Then, using the same vise, pressed the smaller diameter tube into the bearings.
Takes a piece of tuba 40×40 mm (I may be wrong about the section), with the help of an angle piece makes a mark on it from the flat end and cut 7.5 cm long piece by it.
Household category replacement equipment
This list includes accessories for the maintenance of ornamental bushes and lawns. The shrubbery cutter attachment will help clean up a live fence or clear a plot of land from young growth in a short time.
Removable attachment rotary grass trimmer is inferior to a household lawnmower only in terms of ease of operation. Its design allows you to perform the processing of lawn areas with sufficiently high quality and in an extremely short time.
Why make a saw from an angle grinder with your own hands?
If you study the numerous reviews and Комментарии и мнения владельцев of the homemade chain saw from the angle grinder, we can say that it is quite convenient and versatile equipment. By changing the attachments on the angle grinder, you can turn one tool into several: a chain saw and a circular saw. It’s also worth noting that it’s always been cheaper for operators to rebuild old equipment than to buy new. Therefore, we conclude that it is convenient, fast, cheap and versatile to make a chain saw from an angle grinder.
Despite the fact that the technique with their own hands is increasingly becoming an integral part of our everyday life, the leading manufacturers as a grinder, and saws still strongly advise against such upgrades completely abandoned. And the point here is not at all in the competition of production technologies and hand-made production. This warning is based on the fact that modern chainsaws have a very huge torque, many times higher than the same parameter in the angle grinder. How can this threaten?
First, the grinding disc can not withstand such a load and collapse right in the heat of work. Accordingly, the tool itself will lose its efficiency and may fail.
But this is not the worst thing that awaits fans of self-made machines. The worst case is connected not only with health damage, but also with the danger for life of the operator and those around him. Therefore, before deciding on such an improvement, it is worth weighing the pros and cons, and only after making rational conclusions and actions.
Correct installation of the “angle grinder” attachment on the chainsaw
The range of these auxiliary devices is wide enough and is available for most modern chainsaws.
It consists of a leading drum (pulley), which is connected with the motor through belt drive and rotates directly from it, a safety guard and fasteners.
The process of converting the saw to an angle grinder with an auxiliary attachment ready is as follows:
- study the instructions for its correct installation;
- remove the chainsaw guide and also release the clutch;
- mount the pulley on the drive shaft of the saw sprocket;
- connect the belt drive with the saw blade, which will help change the torque of the new device (otherwise you need a reducer)
- take the studs that came with the “angle grinder” attachment, or use those fasteners that were removed together with the saw bar, and fix the adapter with them.
As you can see, a series of uncomplicated actions. and the attachment on the chainsaw “angle grinder” quickly adapts to the motorized tool that almost everyone has.

What chainsaw is suitable for modification?
Before we start choosing a chainsaw, we need to understand what advantages this tool has and why it is chosen as a basic.
- The presence of an engine of excellent performance and power.
- Compactness of the motor.
- The motor does not need to be finalized, it is fully suitable for use.
- You can use the unit in any environment, even in increased complexity.
- Design feature allows the saw to be used in a variety of positions.
- The clutch is specially located to protect the main parts of the tool from damage.
- Convenient output shaft makes it possible to attach additional devices.
When choosing a saw, you should be guided by the following parameters:
- Simple construction and cheap cost of spare parts;
- It is not necessary to use expensive tools, it is better to take already used.
Based on the above, the most suitable are chainsaws Ural, STIHL or Druzhba.
The process of making a homemade chain saw attachment for the angle grinder, is shown in detail on these
In the plate made holes for mounting bolts to the angle grinder and welded to her cage from the bearing.
Adapted an oil can for saw chain lubrication.
Homemade saw, successfully passed the tests.
As a result, we got a removable attachment, a chain saw for angle grinder, quite a useful tool in the cottage and in the garage.
If you are interested in this home-made chain saw, we recommend that you watch the video of the author, which also shows the process of making a saw from the angle grinder with his hands.
Choice of angle grinder for conversion into a chainsaw
The most important factor that you should pay attention to when preparing raw materials for the assembly of the chain saw with your own hands is the power of the angle grinder. The power depends on it, and, therefore, the performance of the future sawing equipment. Take into account the intended purpose of the future tool. If you are going to perform simple and short-lived household tasks, then the power up to 2500 watts will be quite enough for you.
Experienced users of self-made machines also recommend not to use new angle grinder, and give preference to tools that have already been used.
Assembly of the machine design
The height of the construction is barely 10 cm (including the body, protective screen, including the distance to the support plate). The distance between the axes of studs in this case will be 32 millimeters at their height 24,5, the center distance from the shaft to the first stud will be 54 millimeters. Given that the weight of the entire structure (though not including the bar) is quite appropriate, just over 4.5 kg, for mounting you can choose a stud with a metric thread diameter of 8 mm and a thread pitch of 1 mm.
To fix the motor and shaft, a channel is needed. Armed with an angle grinder, cut out of the workpiece mount the desired configuration, and then drill holes under the fastener that connects this design and the chainsaw proper.
When assembling, it is necessary to ensure sufficient distance between the front bowl of the coupling and the support frame. On the other side of the shaft will be mounted the gearbox borrowed from the angle grinder.
The next stage of assembly is the design of the swivel head. You will need a piece of tube with a diameter slightly larger than the shaft with a welded angle to fix the rail, a hollow hexagonal rail, a matching diameter metal rod and a rectangular metal workpiece with holes in the ends to fix the rod and a slit in the top for convenient operation.
The edges of the cut “handle” in the workpiece must be carefully deburred. A guide is attached to the angle piece by welding, and then the resulting structure is connected to the rectangular “handle” using a rod. It may be threaded on the ends of the shaft to make it firmly fastened or it may be lightly interlocked. Then the entire assembly is put on the shaft and fixed in a convenient place for operation.
Well, of course, before assembling the parts should be given as much as possible aesthetic appearance, for which each of them is exposed to scraping and painting.
At the next step it is necessary to adapt the gearbox shaft for the available screw. It is certainly preferable to use a prefabricated part. For those who are not looking for easy ways, it is possible to make a homemade. In the image and likeness of a factory-made screw, a mold is made in which the future screw is cast by means of epoxy glue and fiberglass fabric. After some simple manipulation (sanding, painting) the propeller is ready. However, you need to take into account that the propeller will take a considerable load and it is very important to keep all the dimensions correctly during the production. That’s why it’s better to use a prefabricated part.
After you have made the connection between the propeller and the gearbox shaft with the stud bolt, the final stage comes to an end. Transmission oil is poured into the gearbox, the cover, together with the installed shaft, is fixed using sealant. And then. the final assembly of the entire construction. In order to make it easier to use, you can additionally mount the throttle handle.
Boat owners often use motors to make their boats as fast and maneuverable as possible. The cost of factory assemblies is not affordable to everyone, so most users prefer to create a motor from a chainsaw to a boat by their own efforts. It is worth noting that the upcoming intervention in the basic design is minimal, so the equipment will remain suitable for further use, as intended.
