How to make a renovator out of a grinder. For what purposes does the renovator serve

DIY Renovator Bulgarian nozzle

Homemade nozzle on a grinder, multifunctional tool renovator: detailed photos and description of manufacturing.

Greetings for self.Use lovers! Today, I want to show you a rather interesting home.Made device. We will talk about the vibrational saw, which is also called the renovator.

This is a universal tool, there are many different nozzles on it on sale. In the assembly, homemade is simple, and the characteristics are not much different from the characteristics of the purchased renovator.

The advantage of a home.Made is that the knife is fixed at any angle with a nut, which allows you to perform work in the most inaccessible places.

Let’s look at the process of making a home.Made in more detail.

USHM stand with a protective casing

This product allows you to make the woodworking process convenient and safe.

The stand is made of tungsten steel with a thickness of about 1.2 mm, its dimensions are 13.8×9 cm.

The product is resistant to scratches and corrosion.

Inner mounting diameter. 40 mm, external. 110 mm, weight about 100 g.

The grinder can be installed at different angles, the adjustment range is 2-3 cm.

Direct cut nozzle

A metal nozzle that allows you to fix the tool at an angle of 90 0. With its help, you can make straight.Up even cuts in metal or other material. This design is mounted in holes for fastening the side handle. The overall dimensions of the nozzle are 300200 mm, with a weight of about 500 grams.

Alteration of the chainsaw in an angle grinding machine

Sometimes there is a need to cut off a pipe or a professionalist in a place where there is no electricity. For this, a chainsaw grinder is used, which is easily converted using a purchased prefix.

Renovator from an angle Grinder

To install this device on the chainsaw is necessary:

• Dismantle the tire with a chain;
• Free the tank from oil and remove the clutch drum;
• On the drive shaft of the leading star to mount the pulley of the device;
• Fix the protective device and install the belt gear;
• Put a cutting disk. And the mechanism is ready to work.

The main advantage of the design is that it can be used in places where there is no electricity. When working with such a machine, it is necessary to observe the maximum caution, since the chainsaw is higher than the standard angle grinding. In this case, the risk of destruction of the cutting disk increases.

Modernization of a screwdriver

If there is no drill or chainsaw at hand, but you need to cut materials, you can make a grinder from a screwdriver. The algorithm for its modernization is almost the same as in the manufacture of Ushm from a drill. The main element of the design will be a purchased nozzle. An adapter or spindle of a faulty Ushm.

The advantages of such a power tool include a quick transformation of the mechanism and the ability to use far from the electric network. Homemade can be used in constrained conditions where standard UShM is not suitable due to large sizes.

The main disadvantages of a home.Made device can be called:

• Small resource of the battery (when using a battery screwdriver);
• Low rotation speed of the cutting disk is about 700 revolutions per minute;
• Insufficient electrical engineering capacity.

Such a mechanism can only be used as a low.Power Ushm. With it, you can cut off metal with a thickness of not more than 1.5 mm or a corner of 2020. They can cut the reinforcement with a diameter of less than 8 mm. Use a screwdriver as a full cutting tool will not work.

Description of the renovator

A similar apparatus was invented another 40 years ago, but did not become widespread. He began to be released a few years ago, because the patent period has ended to release it. This is a tool based on the principle of oscillations. They are transmitted directly from the engine through the eccentric. The swinging movements of the nozzle with a frequency of up to 30,000 swinging per minute are obtained. The amplitude depends on the size of the eccentric, but the difference is small. It is the high, adjustable frequency of movement of the head that makes the renovator a useful tool in the household. The renovator is also called a universal cutter.

They are sold in network and autonomous, with a battery. Working from an outlet is much cheaper. Battery models give great freedom of action. Up to several hours of continuous work, but are also more expensive. If you can work near the mains, it is worth taking a renovator with an electroshnur and a complete set of nozzles “for all occasions”.

Network models differ from each other with power, minimum and maximum oscillation frequency, swing angle, nozzle of connecting a vacuum cleaner. Supposed in the case and without it.

Models from 400 watts are able to work longer and at high frequencies, but noticeably heavier. You need to choose what is needed. Weight or vibration frequency. Sitting place for nozzles is the same for expensive and cheap models. Charged models are equipped with the function of replacing nozzles without a key.

The set of nozzles of the device replaces a number of tools:

Basic materials:

In order for the Bulgarian to make reciprocating movements, you need to equip its shaft with an eccentric. For this, the M14 washer and bearing are put on it. Then you need to grind the tab from the steel to install between the internal cage of the bearing and the shaft.

Next, you need to choose a pipe with an inner diameter corresponding to the circumference of the grinder body at the installation site of the protective casing. A ring that needs to be cut along it is cut off from it. On the workpiece along the edges is welded along the nut M8. The result is a clamp, tightened by a bolt. For the convenience of screwing the bolt, the thread in one nut must be drilled.

A segment of a thick.Walled tube is welded to the side. In the presence of a turning machine, it can be machined from the round.

Next, a file mount is made. For him you need to tighten your finger for installation in a pipe welded to the clamp. The finger is made longer than it. From below, a groove under a locking ring is pulled on it. On the part of the part, the carrion under the clamp is cut. A protrusion is left between the flat part and half with the thread.

A steel plate with a hole for access to the shaft of a grinder is welded to the finger at the transition in the thread. Ribs of stiffness are welded to the plate in such a way as to squeeze the bearing. So when rotating, the bearing will move the plate back and forth.

A file for a renovator is cut out of a knife shell on wood. In its back, the groove is cut under the width of the thread thread. The file is applied to the finger and is tightened with a nut through the gasket and the washer.

The main types of nozzles

Due to the oscillatory movements with sufficient strength of the nozzle, different types of operations can be performed based on materials with moderate hardness and even metal. The design of the incisors can be diverse, but the maximum practical application has the details of the optimal shape for each type of work.

Scraping to remove pollution

Scrapers are used for surrounding surfaces from old coatings and binding materials, which include:

They have a flat or curved shape with a straight or arcuate working edge. After such processing, a flat surface remains, which can be prepared for finishing.

Rounded cutting disks with diamond spraying

Such a nozzle is characterized by high surface hardness. With its help, you can:

• Clean the seams between the tiles and panels;
• Chop cracks;
• Delete the influx of cement mortar;
• Cut concrete, stone, ceramic products.

It is not intended to perform a large amount of work, for which it is better to use a specialized high.Performance tool in concrete. But for one.Time stripping and cutting in hard.To.Reach places, such a disk is best suited.

Grinding plates

The type of processing depends on the granularity of the abrasive layer, which can be applied to the part itself, but more often for this are used Fleetical paper sheets. The shape of the plate has elongated protrusions that allow you to fully polish areas along the walls and in the corners.

Semicircular cutting disk with a gear edge

The nozzle of this form is used As a saw. It is made of high.Quality alloy steel. With its help, you can perform an accurate and neat cut along:

Sometimes for a multi.Tool they use straight or curly saws elongated shape, allowing to perform a cut in hard.To.Reach places. If there was no nozzle of the desired configuration in a specialized store, you can try to make it yourself.

Materials for manufacturing:

Homemade will be installed instead of a grinder shield. We make a clamp under this part of the grinder. A piece of a suitable diameter pipe is suitable as a material.

The author makes a groove in a long nut, and then welds a nut to the pipe. That’s all, it remains to cut a nut with a pipe in half and the clamp is ready, one of the halves of the nut must be drilled so that the screw can pass freely.

The hole is also being drilled and a long nut is welded. To weld the nut reliably, the author grinds its end, and this part will now go into the hole in the plate.

A threaded rod acts as an axis, as a result, the nut acts as a kind of bearing, grab such a node when lubricating should be for a long time.

You need to make an eccentric that will wind up on the shaft of the grinder. You can turn the part from the nut, but the steel should be as hard as possible, otherwise wear will occur quickly.

In most cases, the axis simply put a bearing with a displacement and clamped between the washers of the nut. The plate that will interact with the eccentric also needs to be made of strong steel. For such purposes, a piece of a thick canvas from a hacksaw or saw disk is suitable. In general, steel can be tried and tempered.

Further, a steel plate with a hole under the eccentric is welded to the clamp. This will be the basis on which the knife will move.

A knife for a renovator, you can use the purchased, also, it can be made from the canvas from the saw.

Cuts a home.Made perfectly at different angles. In such a device, you can crawl into the most problematic places where another tool will not cope.

How to choose

The purchase of this tool should be taken with special attention. When choosing a home renovator, you should not be guided by the advice of friends or the appearance of the device. It is better to pay attention to the main characteristics of the device:

• Power. This indicator should be based first of all when buying. Power directly affects the effectiveness of the tool when interacting with various surfaces (solid wood, concrete, metals). If the tool is planned to be used for processing soft material, then the power of 150-200 W will be enough. If it is needed to work with solid surfaces, then choose the option with 250-300 watts.
• The frequency of oscillations. This characteristic affects the speed of work and the accuracy of the result. As a minimum indicator on renovators, 6 thousand vibrations per minute are usually made. The maximum value reaches 34 thousand oscillations. Most often for domestic use, devices with a fluctuations frequency of 20-22 thousand per minute are acquired.
• Revolution regulator. This function is present on most modern tool models. Some of them are additionally equipped with a power button, the work of which depends on the force of pressing. The stronger the button is pressed into the renovator case, the greater the amount of its oscillations. This function helps to more effectively process material with different surface density. For example, the maximum speed of work is useful for sawing wood. Plastic is advised to cut at medium speeds, but for metal surfaces it is better to set this indicator to the minimum level. When buying, be sure to pay attention to the presence of an adjustable button.
• Maintaining constant revolutions. If strong loads appear during the tool, this leads to a stop or slowing down the mechanism. This function allows you to maintain the necessary speed speed even when working with complex areas. To ensure constant oscillation speed into the renovator, constant electronics are built. It will be especially useful if active work with a wooden surface is assumed.
• Fastening of the nozzle. For a renovator, you can purchase two types of fasteners. The first of them involves fixing the nozzle manually using the key, and the second is the use of a special fast.Packed device. When buying, you can safely choose a model with the first type of mount, if a frequent change of nozzles is not supposed. The fast.Sounding device will come in handy only in case of active work with constant switching nozzles.
• PAZ features. Many manufacturers make nozzles for their tools with different types of fastening. As a result, some of them may not fit in other brands of renovators. Recently, Bosh has offered to use the same fasteners with the OIS system on all tools. This option is better to choose when buying if you are afraid that the nozzle is not suitable. In addition, the system allows you to use the tool at different angles of the location of the canvas.
• Battery power. Renovators work from the battery, which makes them mobile and independent of external factors. In stores, tools from two types of batteries are sold: compact (easily placed in the device handle) and standard (more powerful and heavy). Small batteries quickly sit down due to a small capacity, but they weigh quite a bit, so it is more convenient to use them. Their power is unlikely to allow you to effectively work with concrete or metal. Large models have twice as much weight (along with the tool it turns out about 2 kg), but they easily cope with hard work. The choice should be made based on the purpose of the tool.
• Additional equipment. The efficiency of work depends on the convenience of using the device. Often in the kit with the renovator there is an additional handle for the second arm. Manufacturers also offer a built.In flashlight for working in the dark and a restriction restriction at the nozzle. It is especially useful during wood processing. For the convenience of transportation, models are supplied with a small plastic case or light bag. These characteristics are secondary, but are able to simplify the performance of tasks.

Often the buyer is faced with the question of which country-manufacturer to choose. It is impossible to answer it unequivocally, because the service life depends on the proper use of the tool and the frequency of its use. Some masters praise Chinese models for their availability and long.Term work, while others criticize popular foreign manufacturers for quick equipment breakdown.

Renovator is a universal tool that will help with the performance of a huge number of tasks in construction. During its acquisition, it is better to contact a consultant who will help to choose a tool with the best characteristics at an affordable price. It is best to buy a renovator from an official dealer, this will allow you to get a guarantee. When acquiring a tool in the secondary market, a great chance to stumble upon a fake.

Most people have probably seen an advertisement for this wonderful tool. On the Internet and on TV, home.Repair masters convince us that the device can replace a large number of tools, and without it, supposedly our skill will be simply useless. Let’s analyze in detail whether we need it which renovator is better to buy, and how those who have already managed to purchase this miracle of technology respond to it.

What can be done from a grinder with your own hands: ideas for self.Making

The question of what to do with dried and cut off branches in the garden, for summer residents, is usually solved simply. This “garbage” is simply burned. And at the same time, if you grind the branches, you can already use them in the garden for various purposes. Today’s story, which Vasily Alekseevich Kayumov sent us from Timashevsk, Krasnodar Territory, will tell you how to make a grinder for branches with his own hands and completely without costs.

My garden plot is small, since most of the territory is occupied by buildings, including a garage, which is a “part.Time” workshop. But the problem of dried branches that necessarily cut down is still quite acute. The thought crept into the head that to burn them, at least, wastefully. After all, if, for example, turn the branches of the Apple tree into wood chips, it is perfect for the smokehouse. With this thought, I went to the workshop, where a grinder caught my eye. Since this all started.

How to choose a renovator?

The acquisition of the tool should be deliberate

It is recommended to pay attention to the following characteristics:

Type of power. Can be network and battery. The first option is suitable for working in the workshop, and in all other cases the second. In any case, the optimal operating mode: 15 minutes. Work and 10 min. Recreation.

Power. Network tool multitool has an indicator 200-500 watts. The battery for homework has a capacity of 12 W, and professional 18 W is professional.

The frequency of oscillations. At high speed, they work with soft materials, at low speeds. Cut and polish solid products.

It is important for working with different materials that need different movement of the nozzle.

Support for constant revolutions. A function that helps maintain the same pace of work

The installed constant electronics provides a constant speed of work with increasing loads.

Fastening of the nozzle. A renovator is a device that has two types of connections: manual fixation with a key and a quick.Linking device. The first option is suitable if the nozzles rarely change, the second with frequent change.

In addition, it is recommended to pay attention to the following additions of the renovator:

Nozzles for the renovator

These consumables differ depending on the tasks that are assigned to them. A multifunctional tool can be equipped with the following types of nozzles:

• Triangular plate on Velcro;
• Carbide sole for polishing;
• Semicircular nozzles with diamond crumbs for metal and concrete;
• Submersible canvases with cloves at the end;
• Scrapers for scraping linoleum or silicone;
• Knives with a double.Edged blade for stroke;
• Consoles for attaching narrow blades and threads.

The oscilizing nozzle for “Bulgarians”. We make “renovator

I took this bastard to see the review cleanly, but it turned out to be quite a worker. There is only one nuance. It is under a small grinder, in it is M10 thread. Therefore, the grinder had to squeeze from the brother. According to a small experience in operation, I can say the following: with all my initial skepticism, it works strange, and even the files will not go out of the nails completely, that is, they are not made of plasticine. In the set, in addition to the actual details of the nozzle and the keys for attaching to the grinder. A couple of pieces and nozzle for sandpaper on Velcro, well, the sandpaper itself 120 one piece

The device is primitive. A bracket is attached to the grinder instead of the casing, an eccentric with a bearing on a spindle, and on the spindle of the nozzle, the instrument itself is a saw, sandpaper or other nozzle. Swing amplitude-about 4-5mm, it is difficult to measure.

As I said, this kit is suitable only for a small grinder, with a spindle M10

Put the nozzle for sandpaper with Velcro

We put a file.

There is a small UPS. The spindle sticks out a little, but there’s nothing to do nothing here. And taking into account the flexibility of the files, this is not the same and the problem.

Operation. During the repair process, I successfully drank wooden skirting boards, sawed slopes, etc.P I tried nails, but there are such nails that you won’t really cut down the chisel, so I decided to chop it, this is a more productive method. I repeat, initially the attitude was very skeptical, but it works, the infection. Again. This is clearly not the most convenient nozzle. In particular, the replacement of the tool that is screwed by a nut, and not quickly as “adult” “renovators”, but if an oscillator is rare. IMHO is a completely viable option. Well, it is important to remember the carvings of the spindle. Not every grinder is suitable

We turn the grinder into a renovator

Step one. We make an eccentricWe make an eccentric that is placed on the shaft of the grinder. The author adapted a radial bearing, it must be fixed with a small displacement, for this we insert a piece of a nail or cut out a wedge from a piece of metal.

Step two. Clampfrom a piece of the pipe we make a clamp that will have to be worn on that part of the grinder where the shield is usually attached. We cut the pipe along, and for the screed we weld two nuts, in one of the nuts we drill a thread.

Step third. Axisassis for a home.Made author turned off on a lathe, it resembles the axis of the grinder. You can easily put different nozzles on such an axis, they are attached with a nut. A sleeve is pulled out under the axis, which is welded to the clip.

The axis movement is conveyed by a special frame made of sheet steel, which is driven by the eccentric in different directions. As a result, thanks to an eccentric, the rotational movements of the shaft of the grinder turn into the reciprocating movements of the axis of the homemade.

Step fourth. We make a knife and experience a homemadeWe make a knife for the renovator, it is best to bend it out of a hacksaw cloth. By the way, you can weld a part of the canvas to the knife with ready.Made cloves from a hacksaw. We collect a homemade and experience. The author cut the pipe in an inaccessible place, the adaptation also works great on wood.

This is where the project is completed, I hope you liked the home.Made, and you found useful thoughts for yourself. Good luck and creative inspiration, if you decide to repeat this. Do not forget to share your ideas and homemade ones with us!

Simple and reliable renovator (nozzle for a grinder)

Step one. We make a clampHomemade will install a grinder instead of a shield, make a clamp under this part of the grinder. A piece of a suitable diameter pipe is suitable as a material. The author makes a groove in a long nut, and then welds a nut to the pipe. That’s all, it remains to cut a nut with a pipe in half and the clamp is ready, one of the halves of the nut must be drilled so that the screw can pass freely.

Step two. Platform and axisFurther, a steel plate with a hole under the eccentric is welded to the clamp. This will be the basis on which the knife will move.

The hole is also being drilled and a long nut is welded. To weld the nut reliably, the author grinds its end, and this part will now go into the hole in the plate.

A threaded rod acts as an axis, as a result, the nut acts as a kind of bearing, grab such a node when lubricating should be for a long time.

Step third. Eccentricyou need to make an eccentric that will wind up on the shaft of the grinder. You can turn the part from the nut, but the steel should be as hard as possible, otherwise wear will occur quickly.

For such purposes, a piece of a thick canvas from a hacksaw or saw disk is suitable. In general, steel can be tried and tempered.

Step fourth. Assembly and testingAfter painting, the author gathered a home.Made, put a knife purchased, or you can make it yourself from the canvas from the saw. Cuts a home.Made perfectly at different angles, and does not vibrate so much. Such an adaptation can be crawled into the most problematic places where another tool cannot cope.

This is where the project is completed, I hope you liked the home.Made, and you found useful thoughts for yourself. Good luck and creative inspiration, if you decide to repeat this. Do not forget to share your ideas and homemade ones with us!

Bulgarian renovator (nozzle)

Step one. We make an eccentricFirst of all, we make an eccentric, it is very simple in manufacturing. We need a radial ball bearing, the diameter of the inner hole should be slightly larger than the diameter of the shaft so that the bearing can be shifted to the side. To fix the desired position of the bearing, the author turned the pin from the nail. At the end, the bearing is clamped by a nut and two washers. It is better to choose the washers so that they do not clamp the cage of the bearing, this will reduce friction.

Step two. Clamp and foundationWe make a clamp on which everything will hold on, this is a kind of basis. We are looking for a piece of steel pipe in diameter a little larger than the part of the grinder on which the shield is placed. We cut the pipe, weld the nuts, the clamp is ready, it can be pulled off with a screw or bolt. In the bolt, you can cut the gap under a flat screwdriver.

Next, we need to cut out the basis that will hold the knife. Here we need a piece of sheet steel, and it is better to choose steel thicker. In the piece, we began to drill a hole under the bearing, and also weld two bolts that will serve as studs.

Step third. Knifenext, we make a knife for a vibration saw, the author decided to use a piece of canvas from the old knife.Haired woman on wood. Such steel will be durable, and the teeth of the saw will be able to keep sharpening for a long time. We cut off the desired piece and weld to it a steel plate with an oval hole, which will transmit movements from an eccentric to a knife.

At the end of the knife, the author cut the cloves with a drill, the effectiveness of the machine will depend on this.

Step fourth. Strengthening the clampSo that everything is reliable, and it is safe to work by home.Made, you need to fix everything as reliable as possible. The author decided to fix the clamp in two more places, and it will not be superfluous. Cut two pieces of plate, rot and drill holes. Additional fasteners will be screwed in those places where the front handle of the grinder is attached.

Step fifth. Painting and testingWe paint parts from a spray can. Thanks to the paint, homemade now looks wonderful, and will not rust.

We collect a home.Made, first we fasten the eccentric, and then the clamp, we tighten all the bolts well so that nothing turns off from vibrations. You can install a knife, the author is fixed with washers and nuts. It is better to use nuts with a plastic lock ring, such a nut will not unscrew from vibrations, and it will also be possible to optimally pull the nuts to reduce the clearance.

Read “Our Father” and launch a grinder, everything works, you can experience. The author easily cuts the board with a vibrational saw. Of course, the main purpose of such a nozzle is to cut out

Nozzle 2. Dewalt firms. Wood and metal.

My favorite nozzle (was). I sawed a lot of it, but I won’t cut steel to her. It’s a pity.Now the conclusions on a home.Made nozzle from a disk from a grinder. The disk costs a new 18 rubles. I used the chopped off the broken edge. With a defect, he began to saw even better new. It saws everything. Tiles, ceramics, glass, steel, etc. I haven’t tried wood, but I think it will be bad to saw. Draws are needed on wood. Sprinkles, of course, but not convenient. Photos of nozzles, as a visual view that any of them can be gnawed from the disk. You can give any shape. Straight, rounded, narrow, wide. Shorter, longer. A bunch of nozzles is obtained from one disk. Inexpensive and good. Truly universal nozzle with your own hands.Thanks.
