Homemade machine launcher
Let’s dwell on this component in more detail. There is a good old version of the start button PNV 30-U.
Standard start and stop device
The principle of operation is as follows. to start the device, you need to forcefully press the “start” button. To disconnect. just lightly touch the “stop” button, which is located above the start key. Very convenient and safe for emergency shutdown.
There are also modern interpretations. The principle of operation is the same. the shutdown button is more accessible than the launcher.
Modern version of the trigger button
The safest way to turn on an angle grinder on a cut-off machine is a non-locking pedal. The control is carried out with the foot, both hands are free at the time of launch. In the event of an emergency, simply remove your foot from the pedal. the instrument is de-energized.
The safest and most reliable way to start and stop the machine is a fixed pedal
Of course, this increases the cost of the design, but safety issues do not have a monetary value.
A lot of designs have been invented, using different materials. wood, textolite, metal profile. In our opinion, the most successful in terms of safety and accuracy of work is a home-made machine made of a steel profiled pipe.
the angle grinder is fixed to the bed. Very convenient mounting option.
There is only one way out. to make a cutting machine with your own hands
What elements must be provided for in the design:
-
Sturdy and heavy bed. The ideal option is to securely fasten the structure to a stable workbench;
The rocker stand must be strictly perpendicular to the table.
If the angle grinder can be fixed in such a way that you can use the standard handle, this is the most reliable option.
A spring that will return the tool to its original position at the end of the cut;
The correct option is a tension spring, with a return travel of at least 25% of the travel of the axis of the angle grinder gearbox.
Mandatory when using any disc, be it an abrasive or a metal circular. The open working sector should not be directed towards the operator.
A device that will fix the workpiece;
If you need accuracy or if you need to cut exactly the same workpieces, you need to use markings in increments of up to 1 mm. A metal ruler connected to a stop is suitable for this.
In addition, once the angle grinder is attached to the bracket, it may become inaccessible. Therefore, the start button on the angle grinder is switched to the “ON” position, the regulator (if available) sets the required revolutions, and the machine is started with a separate starting device.
A do-it-yourself cut-off machine from an angle grinder will increase the safety of work, and improve the quality of the cut

Most do-it-yourselfers use an angle grinder precisely as a cut-off tool. Many will agree that the main advantage of an angle grinder is mobility. in this case it is also a disadvantage.
Tool weight, vibration, gyroscopic effect (especially on discs with a diameter of more than 150 mm) do not contribute to the accuracy of the cut.
All the advantages of a homemade cutting machine in this video
Advantages of Angle Grinder Cutting Machine
If you need to corny cut pieces of an old water pipe for a garter cucumber. accuracy is not a matter of principle. And in the case when it is necessary to accurately cut the material for welding any structure. a tolerance of 3-5 mm can become critical.
The next problem is the observance of the perpendicularity of the cut. It is almost impossible to achieve a straight mowing line at an angle of 90 degrees to the axis of the workpiece while holding an angle grinder in your hands. The same goes for fixed angle cuts. When skewed, abrasive discs are often destroyed, fragments can cause injury.
When you cut a lot of workpieces, after a couple of hours of work there will be no strength at all to hold the tool in your hands, in this case there is no need to talk about accuracy.
Sawing wood blanks is a separate topic. Read more about the disc for the angle grinder for wood and whether it is possible to cut wood with them here. Using special discs that can safely work on wood. you will not achieve a high-quality cut. And the correct circular saws installed on an angle grinder are deadly for the master holding the tool in his hands.
There are factory versions of machines that fix the angle grinder and turn the work of cutting workpieces into a safe and accurate job. But such devices are quite expensive and not always universal. Simply put, finding the perfect fit for your angle grinder is a tricky business.
Factory option for attaching the angle grinder to the bed
How to make a machine from an angle grinder?
Let’s consider in stages the process of making one of the successful copies. The design is quite complex from a technical point of view, but at the same time versatility and functionality exceed the characteristics of factory copies.
A design feature is the ability to adjust the angle grinder overhang along the guide. For this, a pair of old shock absorbers from a car is used.
We use old shock absorbers from the car
Since shock absorbers cannot be used as a supporting structure (walls are too thin), strong brackets are made from a suitable pipe.
We make brackets from the pipe
How to use Your Angle Grinder on Wood
All blanks were purchased at the scrap metal collection point, that is, practically free of charge.
Blanks from ordinary scrap metal. Any pipes and corners will do
We cut structural elements according to a preliminary drawing using an angle grinder, for which the machine is assembled.
Useful Grinder Hack!!! Blender motor to Grinder! Taşlamaya blender motoru taktım!
We assemble the bed of the future machine from the prepared blanks
The structure is welded using a semi-automatic welding machine, which is either in your home workshop or in a neighbor’s garage.
We install a strut of shock absorbers and carefully check the mount
After all major components have been installed, tests must be carried out. Measure the cutting angles, and finally adjust the structural elements to each other.
Then all parts of the machine must be painted.
Be sure to paint everything we did
For an easier movement of the axle, when fixing the stud between the washers, cages are laid from ball bearings of a suitable diameter. Thus, it is possible to tighten the fastening nuts tightly, without backlash. and the movement of the rocker arm will remain light and will not wedge.
The unit for attaching the rack to the bed
The main metal structure is ready. On the bed, you can see the guides for the movable sawing table. The outreach of the angle grinder along the shock absorber axis is fixed with a threaded rod and two nuts. This is necessary when installing angle grinders of different sizes.
General view of what happened
Features of fastening the angle grinder to the rack
The second part of the mount
Guides for fixing workpieces are made for straight cut (90 degrees) and oblique (45 degrees).
Ready-made cutting machine made by hand in a day
By combining the overhang of the angle grinder, the position of the table, the angle of the guides. you can cut any workpieces (the main thing is that the diameter of the abrasive wheel is enough).
During operation, the machine is bolted to the workbench for stability, although its own weight is sufficient for most jobs. Rigidity and reliability are enough to install a circular disk on wood. At the same time, the cutting quality is not worse than that of a stationary circular saw.
The starting device is made as follows. A separate box contains a power outlet and a 15 amp pushbutton switch. The emergency shutdown button has a larger diameter compared to the “on” button recessed into the body.
The power is always on for the angle grinder, after installation and fixing it on the bracket, the power cable is plugged into the socket of the starting device, and control is transferred to its buttons.
We examined the general principles of making a cutting machine from an angle grinder. What will be your option. decide for yourself.
Rewinding anchor do-it-yourself angle grinder
Serviceable rotor for Bosch angle grinder GWS6-100 / GWS 850 MAX. Photo 220V
The rotor is one of the most complex structural elements of an angle grinder. At the same time, it is in a constant rotating state, which creates additional problems in maintaining normal operating conditions. Therefore, the cause of the malfunction of the angle grinder may be an anchor breakage. However, you should not throw away such an angle grinder, you really should do the repair yourself. Rewinding broken coils is not such a difficult task and many can do it quite well.
- Diagnostics
- Required tools
- Laying scheme, winding Interskol 230, Makita 9558HN or 9558BN and other models
- 12 grooves and 24 slats
How to remove
For high-quality diagnostics and possible repairs, the anchor should be completely removed from the angle grinder. If necessary, for work, you can use the information on the link “How to remove the anchor from the angle grinder”.
Laying scheme, winding Interskol 230, Makita 9558HN or 9558BN and other models
The order of winding the rotor windings depends on the number of slots in the rotor core and collector lamellas. The parameters that determine the location of the winding wire on the rotor include the direction and pitch of the winding. The rotation of the spindle shaft (right or left) is just connected with the choice of which side the wire is laid in. When repairing the rotor, it is necessary to record the above data of the burned out winding.
The number of turns and the diameter of the wire is fixed after removing the frontal part of the failed winding, which will allow you to accurately get the complete bundle of wire located in the groove.
Most of the operated angle grinders, regardless of the model (Interskol, Makita and others), are structurally made with lamellas in the amount of 24 pieces and a core with 12 grooves. The winding step is chosen equal to 6.
Required tools
Multimeter Bison. Photo 220V
To rewind the rotor windings, the following basic materials, tools and fixtures are required.
Rewinding can be done in two ways:
- completely in manual mode without the use of any equipment;
- productivity is greatly increased with the use of the simplest devices.
Multimeter or other devices.
The user must know how to handle an electric soldering iron.
The presence of a winding wire, the diameter of which must correspond to the failed wire.
Insulating cardboard or similar material.
Sandpaper, textolite plates, softwood and other materials for auxiliary work.
Epoxy or other impregnating varnish.
Other locksmith tools: hammers, a set of screwdrivers, hacksaw blades, sharp objects such as a well-sharpened knife, chisels and other tools.
12 grooves and 24 slats
Rotor for INTERSKOL angle grinder-2300M, HAMMER. Photo 220V
The rotor winding with such design parameters is performed as follows.
- Sets the winding direction (usually clockwise when viewed from the collector side).
- Insulation made of electrical cardboard and other similar material is installed in the cleaned grooves. The winding wire is soldered to the lamellae according to the old laying pattern.
- The wire is laid in the groove opposite the lamella indicated by the first number and, according to the winding step, is guided into the groove, returning back. The number of such stacks corresponds to the size of the winding turns.
- A circuit with 12 grooves and 24 lamellas is built after soldering the middle of the winding to the lamella and continuing the winding of the winding wire in the same groove. The required number of turns is maintained and soldered to the lamella.This is how the first complete coil is obtained.
- Further, the winding is carried out in the grooves and with the soldering of the middle of the winding to the lamella and the end of the winding to the lamella.
- By winding the coils in the above way, the last of which ends on the lamellas, all 12 grooves and 24 lamellas will be used in the stacking scheme.
Diagnostics
Before proceeding with the repair, you should diagnose the failed angle grinder. This will allow you to determine the true cause of the interruptions in the operation of the power tool, and make it repair with minimal cost. The electrical part of the angle grinder, which includes the rotor, is diagnosed according to certain rules using available devices. Information on how to check the rotor for serviceability can be obtained from the link “Do-it-yourself check, continuity of the anchor angle grinder”.
How to rewind an angle grinder at home, detailed instructions, video
The following video describes the repair of a Makita model angle grinder with increased sparking in the brush-collector assembly. To determine the causes of the defect, a complete diagnostics of the electrical part of the angle grinder was carried out.
The reason for the increased spark was a break in one of the armature windings of the angle grinder. The author eliminates the defect by rewinding the broken winding. After determining the necessary parameters for laying the old coils and then removing them, a new winding is wound. It is produced using a special device.
After the end of winding, the coils are fixed in the grooves using wedges made of wood or other soft material. The author connects the wires of the windings and the terminals of the collector lamellas (“cockerels”) by welding. Be sure to check the electrical circuit of the coils after this operation with a multimeter and a short circuit indicator.
If no breaks, breakdowns and turn-to-turn short circuits are found, the operation of impregnating the winding with epoxy resin is performed. To create conditions for high-quality impregnation, the rotor is preheated. The author describes in sufficient detail the technological methods that contribute to the better flow of the resin into the coils.
Since the rotor rotates at high speeds, it is important to ensure good balance in order to reduce the loads on the bearing units. The author of the video only indicates the presence of this technological operation, more detailed information is not provided. After balancing, the manifold is machined in the working position, that is, based on bearing assemblies. When performing the specified processing, it is possible for mechanical particles to enter the winding, therefore, devices should be checked for breaks and short circuits.
One and the same author repairs an angle grinder of different models: in the first video the SKIL model is being repaired, and in the second video the Bosch model is being repaired. Therefore, the repair methodology in both cases is the same.
It is important to correctly determine the parameters and the winding scheme of the failed rotors on both models. Here, in addition to visual inspection, the author uses a tester, which shows the minimum resistance in the presence of such a connection, to determine the location of a closed electrical circuit for a wire from the groove of the core with the corresponding pin of the lamella. The author recommends performing a graphic representation of the installation scheme with the indication of the required parameters.
Unlike the previous video, in this the author specifically demonstrates his actions when working on a lathe during the removal of the old winding, freeing the grooves from the remaining bundles of wires and the actions when winding the wire. The author is professionally engaged in the repair of power tools, therefore, in the arsenal he has a special device for winding.
After the end of winding, the ends are fixed according to the scheme by bending the bends of the “cockerels” of the lamellas. Additionally, the wire of the frontal part of the armature is bandaged using natural heat-resistant threads (synthetics cannot be used categorically). Next, the ends of the wires are welded with the bent ends of the lamellas and the control is carried out for the presence of breaks and short circuits with the appropriate devices.
After heating the rotor to about 100 ° C (pyrometer readings), the winding is impregnated with epoxy resin.
In the next video, the winding of the armature winding is done without the use of a device, purely by hand. Hand winding has its own peculiarities associated with the fastening of the wire. In the video, it is looped onto the rotor shaft just behind the manifold. The author fixes the ends of the windings to the lamellas without the use of soldering and welding technologies. Lamella hooks are upset at the wire connection points using special attachments in a shock manner.
Several videos are devoted to the repair of an anchor angle grinder model “Metabo”. One of them touches upon the issue of reworking the surfaces of the rotor after impregnation. This information supplements the information previously presented. During this technological operation, resin may get on some working surfaces. The video shows how to clean them.
The simplest do-it-yourself curvimeter from the elements of a burnt-out “angle grinder
Hello. Yesterday I made the simplest curvimeter and I want to share with you the technology of its manufacture.
From time to time it becomes necessary to measure the length of the mowing line curve. For example, when working with a pipe bender, or when making decorative elements (“curls”) for cold forging, the material must be cut to a certain length to make the part. And how to find out this length then? ))) So you have to figure it out, cut it off with a margin, and then, after manufacturing, cut it off and throw away the excess. So the idea arose to acquire a curvimeter.
The network has a lot of descriptions of the simplest such device, which does not even have any scale. The essence of its work is that the impeller does not rotate freely on the axis, but is screwed onto the axis by means of a thread. The craftsman turns the wheel until it stops, and then rolls it along the curve of the mowing line on the sketch of the part. In this case, the wheel is unscrewed along the thread by a certain number of revolutions. It is enough to turn the device over and roll the wheel until it stops along the ruler or tape measure. at the point at which it will again be wrapped all the way and you need to read the readings. This will be the length of our mowing line curve.
Here is such a curvimeter and I decided to assemble it. I decided, then I decided, but all hands did not reach. And so, being at my construction site, I decided to make a garden bench from the remnants of building materials. I drew a sketch. And again, before using the pipe bender, it would be good for me to know the length of the section of the profile pipe, so as not to cut off the excess. I thought. And I decided to assemble the curvimeter first. Construction. this, of course, is not a workshop, but everything you need was available. And the adaptation is primitive. can it and “on the knee” collect.)))))
So what I needed:
Compression nut from angle grinder.
2. The handle from it is the same.
3. Cutting hairpin М14.
4. Nut М14 (2 pcs.)
5. Cutting a metal strip 25 by 4 mm.
I have long decided to use a nut from “Angle Grinder”. this is a finished wheel with a thread inside! I decided to take the handle too “angle grinder“. it makes no sense to do something by yourself “handshake”, if there are ready-made solutions! Besides, I have enough of this stuff. there is a box with the remains of a power tool in the workshop! Periodically, these residues act as “donors”, But. Nuts and handles do not break (In an angle grinder, the rotor and gearbox usually fail), so a lot of them have accumulated. So that, “with a black sheep. at least a tuft of wool!” )))))
But this box. in a workshop. I am. at a construction site. And therefore, without further ado, I disassembled one of my angle grinders!
As you know, on the spindles of all angle grinders, the thread is the same. M14. Therefore, it is necessary to use a stud with such a thread as an axis. I used such a hairpin in the manufacture of the carriage and vice of my cutting machine, so I had trimming.
For the manufacture of the bracket in which the axle-hairpin will be mounted, I used a strip of 25 mm, the cut of which I found in my “scrap metal”.
I worked with the same stepped drill. (A handy thing, I tell you. And you can drill a huge diameter with a household drill, and you won’t break, no matter how hard you try!)))). However, there are also disadvantages. material no thicker than 5mm, and difficulty in sharpening.
Next, I cut off the excess with an angle grinder, and rounded off the other, using an emery-flap wheel. Got a more finished look, so to speak:
All. You can start assembling.
Initially, I thought to just weld the stud to the bracket. “Drip” on both sides, that’s all. But, during the assembly process, I noticed that my curvimeter travels a path for a full stroke, a little more than three meters. (Accidentally so “roundly” happened))). Therefore, I decided to secure the stud in the bracket with nuts. Then the full stroke length can be adjusted exactly! It is unlikely that I will ever measure something longer than 3m, but. but what if?! ))). Let’s have this option. you roll it all the way, turn it over, and roll on, knowing that you turned it over exactly three meters.
Two nuts had to be screwed on each side. one inside the bracket, and clamp the other outside.
The design turned out to be very cumbersome (M14 nuts are not very small))). And I decided to just cut two nuts in half. (I don’t know which influenced more. The bulkiness of the design, or the fact that I had only three in stock. One was missing!))))
.Since, as I already said, I didn’t have a vice either, I decided to use a hairpin. He screwed on the nut a little, a couple of turns and locked it with the second. Then he marked it in half, using the eye as a caliper, and the nail as a planer)))):
All. The curvimeter is ready;
STOP. Not ready yet. Need to paint! Dismantled, sprayed with a spray can, preheating the metal with a hair dryer (It dries very quickly).
Now I’m ready:
Stop. Again “joint”. The site name was misspelled.
Okay, let’s redo it.)))))
True, I did not start making a bench that evening.)))). Played with a curvimeter.)))). Nothing! There will be another day off.
. I’ll add it two days later. Thanks for the advice in the comments. Here is a short video overview:
Where to use a burned-out angle grinder
An anchor angle grinder, if it cannot be restored, for example, when the lamellae or winding are damaged on it, it can be used to make an adapter adapter for a screwdriver, drill, etc.
In principle, for this, the anchor has everything we need, namely:
- Smooth surface and round shape;
- A rod that could be hooked on;
- Sanding belt slots.
The principle of operation of such a drill bit is very simple.
You take and install it in the chuck, after which you begin to process various workpieces with the nozzle. They can be made from materials such as wood, plastics, metal and even glass with ceramics.
Nozzle manufacturing process
First of all, we take and cut off the rod where the bearing is located from the burned-out anchor of the angle grinder. We do not need all this in the future. It is best to cut the anchor with the same angle grinder, only you need to fix it firmly in a vice so that it does not fly out of there.
Then you will need to get rid of the gear and blast off all the wire available at the anchor. We also do not need a wire. To burn off the wire, and not to suffer and unwind it by hand, we will use a small gas burner.
As a result of all of the above manipulations, a clean blank of an anchor should lie in front of us, without wire, bearings and gears. It will be necessary to work a little more and grind the surface of the anchor with fine-grained emery paper.
Homemade from an angle grinder with a burnt out anchor
The motor and gearbox of the angle grinder can be made excellent attachments for work in the home workshop. But what if the motor of the angle grinder is completely out of order?
For example, I had one case when after buying an angle grinder, a few days later the armature winding was damaged. I don’t know what they did there, but since then I don’t buy cheap angle grinders.
In general, while cutting metal, an unpleasant smell of burnt plastic escaped from the body of the angle grinder. Then sparks and the characteristic sound of the anchor jamming. Having disassembled the angle grinder, I found out that the armature winding was badly damaged, probably, the wire began to cling to the body during operation.
Just like that, buy cheap low quality angle grinder. They will not mention the manufacturer of the angle grinder, but I will only say that it is ours, domestic. In general, without thinking twice, I decided where to use an angle grinder with a burnt out engine. What happened, see below.
Installing the sanding belt
For the next job, you will need a piece of sanding belt. It will need to be cut into strips corresponding to the width of the anchor, then bend the edges and stick them into the slots. This must be done with each groove on the anchor.
The result of the work done will be a petal nozzle for grinding a wide variety of products. Well, if you need a regular, circular grinding attachment, then here, too, an anchor from a burnt-out angle grinder will come to the rescue.
Just take and wrap the anchor shaft with sanding paper, cut off a piece and insert its ends into one of the grooves. By installing the armature rod into the chuck of a drill or screwdriver, you can usefully use a homemade angle grinder made from a burnt-out engine.
Cultivator
For motorized soil cultivation, a cultivator is made from a trimmer with your own hands. The motor power must be at least 2 HP. from. When using a trimmer, you need to stock up on an extension cord so that the production process takes place throughout the entire area.
The main part of a motor-cultivator is a nozzle. It is suitable for garden fork rods 10-15 cm long.
The part is manufactured as follows:
- first you need to flatten the teeth to a width of 1 cm;
- sharpen cutting blades for milling cutters on an emery wheel;
- cut a ring with a diameter of 10 cm from a metal sheet with a jigsaw;
- grind the workpiece;
- weld 3 cutters to a steel circle at an equal distance from each other.
If there is a reverse thread, the nozzle is screwed on, having previously welded the pipe with a nut.
Ice screw
Trimmer ice auger is a low-power unit for winter fishing enthusiasts, characterized by its low weight and convenient transportation. In order to save money on the purchase of new equipment and the forces required for manual ice drilling, anglers make them from old trimmers. For this you need:
- lawn mower;
- factory or homemade drill;
- materials at hand.
It is difficult to make an ice screw at home. Parts to look out for are the augers and knife base.
To create augers you need:
- Calculate the dimensions of the product segments.
- Prepare metal blanks, mark, cut out a sector, weld the segments together. The result is a steel spring welded on one side.
- Stretch the spring by a predetermined step on a special machine in order to weld the segments on the other side.
- Grab the flange and weld it to the pipe.
- Boil the auger connections and paint.
- When choosing the rotation of the auger, the direction of rotation of the gasoline tool is taken into account.
Converting the trimmer to a gas drill is suitable for machines with a folding boom. The connection adapter is the easiest to prepare.
If it is necessary to increase the rigidity and stability of the mechanism, make a strong frame for attaching the gearbox and motor.
Motor-drills. units for making holes for installing wooden piles, laying a foundation, drilling wells. The principle of operation and manufacturing method is similar.
Trimmer
The owners of summer cottages and household plots will be interested in the following video. Many of them use trimmers to keep the area in order. The option of failure of the electric motor installed on such a device is not excluded. The author suggests using an angle grinder instead. Why is the bracket made of waste materials, which is mounted on the site of the burned out engine. In addition to the bracket, an adapter should be made from the spindle of the angle grinder to the flexible shafts of the trimmer. An angle grinder is attached to the installed structure and the trimmer is ready for mowing overgrown grass.
The number of revolutions of such a modernized design is of the order of 10,000 revolutions per minute. At such speeds, the grass is mowed quite efficiently. It is possible that the use of an angle grinder of the minimum range of powers to reduce the weight and overall characteristics of the trimmer will lead to overheating of the angle grinder during operation. Monitor the temperature of the angle grinder gearbox and take breaks if necessary.
10 Ways to Use a Gearbox from an Angle Grinder
The angle grinder is composed of electrical and mechanical parts. During operation, the electric drive may burn out, if the gearbox is in good condition. The opposite option is possible. the gearbox parts (cracks appeared on the housing, the gears are worn out, the bearing units are out of order) have critical damage, if the electrical part is working properly, the angle grinder. Some craftsmen do not write off the entire angle grinder in such cases, but try to find an application for its serviceable part. The most inventive after buying a new angle grinder find the use of a whole previously operated angle grinder in other mechanisms where an electric drive and a gear transmission are required.
Cultivator drive: Mole and more
Land owners will benefit from the experience of the author of the following video. The gasoline internal combustion engine on the cultivator is out of order. In its place, the author invented a mount for an angle grinder and connected the spindle of the angle grinder gearbox with the cultivator gearbox. The RPM of an angle grinder is definitely higher than that of a gasoline engine. However, the performance improvement advertised by the author is unlikely to occur. The problem of overheating of the collector motor will remain and frequent stops, as a protection against it, will remain. Although for owners of relatively small areas, the use of such a cultivator will be effective.
On a scooter
For those who are obsessed with technical creativity and who want to make their little children or grandchildren happy, the idea of creating an electric scooter is in the next video. To do this, you will need a cordless angle grinder that is not currently used, a typical lawn mower wheel drive gearbox and materials for the manufacture of the scooter itself. Of course, the main thing in the success of this homemade product is that the master has the universal skills of a locksmith, turner, welder and many others. By the way, the angle grinder can be easily removed and used for its intended purpose.
Homemade products, what you can do with your own hands, where to adapt the gearbox
A significant number of mechanisms operate at the number of shaft revolutions after the gearbox of the angle grinder. Therefore, there are more options for using the angle grinder gearbox for the operation of other devices. Together with non-standard ways of using the whole angle grinder for homemade products, the masters of technical creativity create interesting compositions. Some are presented by the authors in specially filmed videos.
Materials:
- metal perforated plate (100 mm x 240 mm)
- 2 hacksaw blades for metal
- 4 screws and 4 nuts M5
- 4 washers and 4 oversized washers
From a safety point of view, hacksaw blades should not be completely hardened.
Everything you need to make a nozzle
The most difficult thing in making a nozzle is to symmetrically mark and make holes for the knives and the trimmer shaft. That is why a ready-made perforated plate is chosen.
Work on the frame and ruler
The simplest frame will consist of frames mounted on one axis. The lower one must be fixed on the platform. If the tool is large, it is better to use metal. An angle grinder is screwed to the upper frame, which will rotate vertically according to the principle of a pendulum. A spring is required to lock the home position.
A fastener is welded to the lower frame, which will consist of a clamping angle and a clamp. Measuring parts should be provided in the machine. In this case, a movable ruler with a limiter is better suited. It is welded to the pipe.
Self-development to a cut-off machine
The simplest homemade tool is a machine made from a small angle grinder. The work will be accompanied by a minimum of costs, and the manipulation will take a few hours. The outlet structure will be a long metal tube that serves as a handle and frame.
A transverse strip made of metal with two holes for fastening the tool is welded to one of the ends. On the same side, the pipe is fixed to the angle piece on the movable shaft. The first one can be fixed to the work table or to the floor in the work room. If you are faced with the question of what can be made of an angle grinder, you can perform a cutting machine following the described algorithm. According to him, on the opposite side of the mount, it is necessary to fix the spring, which will ensure the return of the structure to its original position. At the end of this stage, you can use your homemade product. It will only be necessary to correctly install the device.
This version of the machine is the simplest solution for metal processing, while complex work will require precision, therefore, the design for solving such problems must be made more stable, which means that work will have to be approached more thoroughly.
Electronics
In order to make the work more convenient, the design should be supplemented with a switch button or a start pedal. In the first case, a low-voltage relay is used, through which voltage will be supplied to the instrument. This uncomplicated design will allow you to free your hands and achieve an even cut without the use of a vice. On this you will also save time, because you do not have to make accurate measurements.
Making a wall chaser
What can be made from an old angle grinder? This question is often asked by home craftsmen. But if your angle grinder is working properly, you can make a wall chaser out of it. By using equipment without modification, you put yourself in danger. In order to avoid risk, you can make a nozzle with a solid base, it will allow you to make cuts in the walls for the entire diameter of the disc.
This addition is a foot in the form of a stop that allows you to move the tool along the wall. The efforts will be uniform. When you make such a device, take the time and install a closed cover, which will be complemented by a branch pipe for connecting a vacuum cleaner.
Making a machine with a bed
You can also make a cutting machine from an angle grinder. For this, the following tools and materials should be prepared:
- profile pipe;
- steel corner;
- Metal sheet;
- welding machine;
- drill;
- channel;
- bearings;
- shaft;
- pipe;
- spring;
- pedal relay.
If desired, the sheet of metal that will go to the platform can be replaced by chipboard. The stove will become an easier option. There should be several bearings, they should be the same.
