What can be done from an angle grinder gearbox

Homemade products, what you can do with your own hands, where to adapt the gearbox

A significant number of mechanisms operate at the speed of the shaft 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 a whole angle grinder for homemade products, the masters of technical creativity create interesting compositions. Some are presented by the authors in specially filmed videos.

Sliding gate drive

The following video shows one of the options for a sliding gate drive based on a gearbox from a burnt-out angle grinder and an old electric screwdriver. The operator is equipped with an automatic device for controlling the opening / closing of the gate. A chain drive with a drive spindle on the gearbox spindle operates at high speeds to perform the gate control function, therefore, increased operating noise is generated.

Plasma cutting attachment

Plasma cutter is used to cut round workpieces. The frame structure, as shown in the following video, acts as a fixture for securing and adjusting the diameter of the resulting blanks. The “trick” in the use of an angle grinder gearbox is that its conical pair changes the direction of rotation by 90 °. Thus, the manual drive creates rotation in the horizontal direction, and the gearbox converts it to the vertical direction and ensures the correct functioning of the plasma cutter.

On grass trimmer

The owners of summer cottages and personal 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 grass trimmer. An angle grinder is attached to the installed structure and the grass 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, grass is mowed quite efficiently. It is possible that the use of grinders of the minimum range of capacities to reduce the weight and overall characteristics of the grass trimmer will lead to overheating of the grinders during operation. Monitor the temperature of the angle grinder gearbox and take breaks if necessary.

On an electric screwdriver

The screwdriver, which the author of the following video uses, already has to work at maximum loads when threading on the M8. The use of a reduction gear from an angle grinder increases the amount of torque, and allows you to cut threads in more comfortable conditions. Here, a burnt-out angle grinder is used, where the rotor is cut to a length that at the same time allows you to securely fix the end from the cut shaft in the chuck of an electric screwdriver and firmly fit the plastic case of the angle grinder on it. For a more thorough connection, the electric screwdriver with the angle grinder body is fastened with clasps, while the gearbox bearing of the angle grinder fits into its seat. Drilling and tapping with prepared tooling for such work does not require any additional effort.

Machine

As one of the structural elements of the drilling machine created by the author in the next video, the gearbox from the angle grinder (you will learn how to disassemble the gearbox here). Working in tandem with an electric motor from a washing machine makes it possible to obtain drill revolutions in accordance with the required technological modes of material processing. The rotor of the angle grinder is trimmed to the length necessary to securely attach the rubber sleeve, which acts as an elastic coupling. The other end of the sleeve is attached to the motor shaft. Fastening is done with clamps.

The machine has several degrees of freedom. In addition to lifting up / down using a handle and spring-loaded suspensions, the linkage system allows you to change the location of the cutting tool in the horizontal plane. It is advisable to use as a tabletop device for making holes in metal and wood parts.

Don’t Throw Away the old Angle Grinder! Hack

ways to use the angle grinder gearbox

The angle grinder consists 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 of the angle grinder is working properly. 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.

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. If you think about it, welding can be replaced with strong bolts, which is what you need a drill for. This option will allow you to disassemble the machine if necessary.

Making a wall chaser

What can you do with 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. At the same time, 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.

Self-development to a cut-off machine

The simplest homemade product 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 acts 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 done from an angle grinder, you can make a cutting machine by 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 install the device correctly.

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.

Making a miter box

You now know what can be done from a burnt-out angle grinder. But if the tool has not failed, and you want to expand the range of tasks it performs, you can make a miter box. For this, the table top is made to rotate. This will allow you to cut a baguette, plinth or profile from different materials at a certain angle.

The table top is installed at an angle, the corresponding disc is mounted, then the cutting is carried out, which turns into a pleasure. With the help of such a homemade machine, you can cut paving slabs diagonally, thereby diversifying the ways of laying it.

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 tool. 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.

Features of making homemade products from a broken tool

The angle grinder is not an eternal thing, so after it breaks down, you can use the equipment for other homemade products. Sometimes it happens that a motor or gearbox breaks down. The housing may break or the gear teeth may be cut. However, you should not rush to throw away the device. Something one of the two angle grinder assemblies may still work.

If you’re deciding what to do with a broken angle grinder, the engine should be considered. But due to its high speed, it is not often suitable for alterations. This part of the angle grinder can be used as a basis only in the case of making an engraver. You will need to cut off the gearbox and fasten the chuck to the shaft for different nozzles, there are a huge number of them on sale.

If you are still wondering what can be done from an angle grinder that has an engine flying, you can use a gearbox. It is metal, compact and has a powerful bearing on the output shaft. Due to the existing threaded connections, the gearbox has good mounting possibilities. The reducer can be mounted on a drill using a special adapter. But on such tools, the cut-off wheel can be source of danger. Therefore, it is recommended to adapt the gearbox to situations that are far from the original function of the angle grinder. For example, you can make a sander for wood flooring. You can comfortably carry out this dusty job thanks to the speed control and bevel gear. A large area can be covered with a wide disc, which speeds up the process.

Quite often, home craftsmen think about what can be done from the gearbox of an angle grinder. The tapered assembly is compact, so it can be used for a variety of tuning and adjustment tasks. For example, to adjust the working table on the machine. The gearbox is also widely used to create outboard motors. The problem of sealing the propeller shaft can be solved by sealing. Outside the gearbox, an additional oil seal can be installed on the propeller shaft under the trim ring. But in the case of motorized bicycles, an oil seal is not needed.

But if you are still wondering what can be made of an angle grinder, you can use its gearbox by transferring torque to the wheels. The described unit is installed on the wheel axle. Using a traditional chain, you can adapt the protective casing as a gearmotor holder. The electric motor may not be limited by using an internal combustion engine. In this case, the gearbox of an angle grinder will be able to withstand even high loads.

When thinking about what can be made from an angle grinder, you might consider making a coffee grinder. It is suitable for lovers of an active lifestyle who prefer to sit from time to time in the silence of the forest with a cup of fragrant freshly brewed coffee. You don’t have to think about the engine, because the mixer has a special shaft that rotates custom nozzles.

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, metal is better. 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.

First Option. Using a Drill

The first option has a simpler solution. Let’s say you need to make a miniature grinding wheel that will be installed in a drill or electric screwdriver. To do this, we can take a broken disk. On it, using a caliper, draw a circle of the required size. Then, along the drawn circle, we cut out the future miniature disk. In its center we drill a hole into which we insert a bolt with a diameter of 6 mm. Put on a washer from below and tighten with a nut.

The bolt will be the axis of rotation of the disc. We insert it into the chuck of a drill or electric screwdriver and clamp it. Such a tool can be used to cut materials in hard-to-reach places or small in size. Finished parts can be sanded.

Сool idea for a vacation from an old angle grinder!!

It is not difficult to make a miniature milling cutter for cutting small parts from plastic or wood. To do this, we take an ordinary tin cork from a glass bottle. In the center of it we make a hole for installing the axis. The axis can be the same bolt with a diameter of 6 mm. We align the edges of the cork and cut out the cloves. It is desirable to make minimal markup.

Such a cutter, loaded into a drill or electric screwdriver, is able to easily cut small wooden strips, for example, for modeling. Plastics also lend themselves to this simple tool.

The second option. Self-assembly (2 videos)

If the task is to make a miniature tool with your own hands, then you must initially select an electric drive. As an electric drive, a motor from various devices is suitable. a printer, an old cassette tape recorder or from an ordinary children’s electrified toy.

Depending on the power of the electric motor, you can build a mini angle grinder in two directions. The first direction is the use of a mains power supply. For example, from an old mobile phone. The second direction provides for a completely autonomous model from a motor, which will be powered by batteries or accumulators.

The difference between the two is in the design of the case. In the first case, space is required only for the electric motor, and in the second it will be necessary to install the battery compartment.

It is very convenient to use a piece of PVC pipe for the body. If its diameter is slightly larger than the diameter of the electric motor, then electrical tape can be wound around the motor. You can fix the engine with a glue gun.

As plugs, you can use plugs that are put on PVC pipes during transportation and storage. In the front plug it is necessary to make a hole for the motor shaft, and in the rear plug for the power cable. The power connector and the switch must be fixed to the case.

The ideal option would be to be able to attach a collet to the shaft. This will allow the use of standard burs, drills and custom mini mills and discs. If you cannot install the collet clamp, then you can connect the shaft and the cutting tool using a double contact from the electrical block.

In a similar way, you can make a case for a mini angle grinder with autonomous power supply. Only after installing the engine in it, it is necessary to install the battery pack. The battery wires will be connected via a switch mounted on the case.

In both cases, on mini grinders, you can use both a home-made tool and a standard industrial one. drills and drills.

useful things that can be done from the motor and gearbox of a broken angle grinder

For a long time, the angle grinder has served you faithfully. How much metal has been cut over the years of service! Now the tool is becoming unusable. a piece has broken off, the buttons are sunk, everything is loose. You have to buy a new one, but it’s a pity to throw away good material. What you can start up the engine and gearbox of the old tool, we will tell you in this article.

Install the new disc of the angle grinder

Install the new grinding disc onto the drive bolt in the same way as the old one onto the drive bolt.

Finally, hand tighten the new disc in the opposite direction from which you removed the old disc.

The angle grinder should now work properly. If you need to replace the angle grinder motor after installing a new disc, you can easily do it now.

How to Repair a Broken Knife Tip

Whether a kitchen knife falls to the floor or a knife is used to loosen a screw, a broken tip is likely to suffer throughout the knife’s life.

In the video above, special guest Steve prepares to repair the tip of a Wusthof mating knife at Ken’s Work Sharp Onion Sharpener with Blade Grinding Attachment. tool that he developed over 22 years (and this number continues to grow) at Work Sharp. First we had to break the tip to get it repaired.

Tip: Maintain the original cutting geometry

When a part of the knife tip is broken, it is impossible to keep the same cutting geometry as the original shape, but we can get closer. The knives have both a primary sharpening taper and a distal taper, which means that it becomes thinner both closer to the cutting edge and closer to the tip. To maintain geometry, sand the knife shaft until it meets the bevel to form a new tip.

Reduction of the spine to the bevel. it is not only the key to maintaining an efficient and thin cutting edge, but also a safety measure when it comes to folding knives. With many folding knives, the spine of the knife remains open outside the handle when closed. If a knife with a broken tip was repaired by lifting the bevel towards the spine, it is possible that the new tip may pop out of the knife handle when closed, presenting a dangerous sharp tip in your

Tip: Shape your spine for comfortable use

The shape of the knife blade is very comfortable and we want to keep this original shape well. When removing material from the spine, try to match the shape of the original spine. In this case, we wanted to round the spine down until it meets the bevel, so that it is convenient to work with your finger along the spine near the tip. This meant we had to sand about 1.5 inches from the tip to keep the shape uniform.

Using a knife sharpener with a coarse abrasive. the best way to quickly remove material and repair the knife. The coarse diamond insert can handle the job or the belt system just like our own Work Sharp tools. Changing the shape of the knife can be done with other power tools and should be done with extreme caution. Belt sander or bench sander. an effective way to remove material, but it also generates a lot of heat very quickly. It is important that the knife stays cool.

Tip Take your time and keep a wet cloth close to

How do I know if my knife is heating up? The heat treatment of the knife is not affected until the blade is about 400 degrees. The metal becomes unpleasantly hot to the touch at temperatures around 100 or 120 degrees. If the knife is hot to the touch, take a break or cool the blade with a damp cloth or sponge.

Once the mold is set, sand all newly sanded surfaces with each abrasive to smooth out the edges. Grinding the spine can create a 90 degree sharp edge that is inconvenient to work with. Each abrasive can be processed while sharpening.

How to sharpen a knife on the Ken Onion Edition knife sharpener with blade sharpener

• Set the desired bevel angle between the pulleys.
• Put on coarse tape.
• Turn on the machine and lock the speed to medium.
• Place the leg of the knife on a horizontal platform, keeping this angle, raise the knife so that it touches the belt between the pulleys, and pass the bevel through the belt.
• Repeat step d. 3-5 times or until a burr appears. Then repeat the same number of movements on the opposite side.
• Change the belt to the X65 belt and run the knife along the belt 2-3 times on each side, alternating sides with each movement.
• Repeat step 6 with a finer, finer abrasive, applying light pressure and maintaining firm contact with the belt.
• Paper cut test

We now have a repaired tip and a sharp knife!

For outboard motor

The gear ratio of the angle grinder gearbox allows the propeller to give the required rpm for efficient operation. Electric motors from many household devices are suitable for the production of a homemade boat motor. In the following video, an electric motor powered by a car battery through a long shaft in a pipe and a gearbox connected to it transmits the rotation of the propeller.

The angle grinder gearbox is not intended for work in the water element. It is imperative to revise it. Firstly, make a seal at the spindle outlet from the gearbox, and secondly, plug the place from where it is necessary to remove the fixing mechanism of the angle grinder from turning when changing the tool. Such measures do not guarantee 100% water penetration into the gearbox. However, a more frequent change of lubricant will make it possible to work out the gearbox of an angle grinder as a unit for a boat motor for a rather long time.

Machine

As one of the structural elements of the drilling machine created by the author in the next video, the gearbox from the angle grinder (you will learn how to disassemble the gearbox here).

It is advisable to use as a tabletop device for making holes in metal and wood parts.

Homemade lawn mower

Instead of a new lawn mower, it is quite possible to assemble a model with your own hands. for this you need an angle grinder and straight arms.

This lawn mower is less powerful and small in size. In most cases, instead of knives, special fishing lines are installed on it in order to cut the grass. this is shown in the photo. A mower from an angle grinder is convenient in that the tool can be easily removed and used for its intended purpose. How to make a lawn mower from an angle grinder is described here.

Homemade wood trimming machine

With the help of a miter saw, the summer resident will greatly simplify his life. A saw of this type is offered in all building supermarkets, but a proprietary miter cutter is very expensive.

In order not to buy such a tool, it can be assembled with a broach, using improvised material and old tools that almost every owner has in his arsenal. Now we will see how you can assemble a homemade miter saw with your own hands. An example of making a miter saw can be seen here.

What you can do with an angle grinder: DIY from an angle grinder

The angle grinder is perfect for use on a stationary machine and as a more accurate tool, and as a motor with a gearbox for all sorts of homemade products. The angle grinder is very often used for construction, repair, and installation tasks. an angle grinder is advantageous in that the number of options for its application increases with the number of attachments used.

DIY wall chaser from an angle grinder

The angle grinder can be used for tasks such as cutting cuts in a wall. These are cuts for laying wiring, pipes, and other elements. If you take a stock angle grinder for such work, the immersion depth of the disc is very difficult to control. To solve this problem, a special frame can be made.

Such a frame is made in the form of a sole with a stop, with the help of which the tool can be moved along the wall with a uniform deepening. Thus, the strobe of the desired depth will be learned. To make such a wall chaser, you need to remember about such details as a protective cover and a special dust collector. For the latter, a bag can serve, but it will be more convenient to connect a hose from a vacuum cleaner.

Drilling machine from the engine from the washer and the gearbox from the angle grinder

Materials and tools used by the author:

List of materials:. washing machine motor 650W / 1350 rpm;. gearbox from 180 angle grinder;. angle;. round pipes;. sheet steel;. bolts and nuts;. springs;. switch;. cable with good insulation.

Drilling Machine Manufacturing Process:

Step one. Modification of the gearbox For the machine, you will need a gearbox from an angle grinder by 180, it underestimates the engine speed more than a gearbox from a 125 angle grinder, as a result, we get a higher torque, and the axis in such a gearbox is thicker. The author, using an angle grinder, cuts off a piece of the anchor and knocks the rest of the anchor off the axis. You will also need to cut off a piece from the angle grinder body in order to screw this part with the bearing seat to the gearbox. If there is no such part, you can weld it yourself from sheet steel, using a piece of pipe as a holder.

Step three. Base We make a base for the drilling machine, it must be as strong as possible so that the whole structure does not fall. You can use a piece of a suitable channel as a base. If there is no channel, it can be welded from thick sheet steel. We weld the ears to the base, for fastening the machine to the base with bolts.

We also weld 4 racks to the base, these can be pipes or steel rods. First, we insert the rods into the carriage, and then grab them to the base. This is the only way to set the stands correctly.

Step seven. Final touches and tests We install a drill chuck on the gearbox shaft to screw the chuck, you can weld a nut for an angle grinder to it or cut a thread directly in the chuck.

We paint the frame so that it doesn’t rust, now the machine looks great. We put a convenient switch to quickly turn off the machine in case of something. The machine is ready, the author put a huge drill in the chuck and drills with his monster everything in a row, from wooden beams to thick sheet steel.

The machine has shown itself perfectly, a machine for a real man. This completes the project, I hope you liked the homemade product, and you found useful thoughts for yourself. Good luck and creative inspiration if you decide to do this again. Do not forget to share your ideas and homemade products with us!

Angle Grinder Hack! Don’t Throw Away the old Angle Grinder!

What can you do with a gearless angle grinder

an angle grinder without a gear is a fairly powerful electric drive with a value rarely less than 0.5 kW. Such a device can be used in homemade machines for the production of various types of mechanical processing (stripping, cutting, grinding, etc.).

Important: do not throw away the emergency gearbox, but modify it by removing all unnecessary parts, for example, on a lathe, leaving only a part of the housing with the bearing assembly. This design of the drive shaft will maintain its rigidity when transferring the load. Further, instead of the drive gear, the angle grinder is fixed with a drive pulley of a suitable diameter and, using a belt drive, torque is transmitted to another driven pulley sitting on the working shaft. The working tool is set according to the nature of the work performed.

The option of using high speed electric drive of the angle grinder is effective when performing engraving work. Here, no intermediate mechanisms are required to set the working revolutions, but only the problem of how to connect the flexible shaft used in engraving technology with the shaft of the electric drive should be solved. Preserving a part of the gearbox housing with a bearing installed in it (! The replacement process of which is presented in a separate article) is an important condition for the operability of the structure.
