The nozzle on the drill for polishing with their own hands

Felt wheel for polishing: how to make their own hands

The most common products for processing the car body are: sponge-shaped, abrasive with different degrees of grit, felted, having a soft surface. They are conventionally classified according to the type of production into two types:

  • petal-shaped (has high capacity and high price)
  • flat-grinding (made as a rubber disk that has an additional coating for processing).

The material for these items is dense foam rubber or felt, which has different diameters. However, kits are sold that consist of several elements, which have different purposes and complexity of making.

Tools and equipment

The circles have different hardness, are divided into several types:

  • Hard. used when eliminating scratches and small chips on the parts.
  • Soft and medium are used for sanding and polishing.
  • Relief-used when it is necessary to achieve gloss over a large area.

At the service station are used 2-3 types of circles at restoration of the auto coating.

  • Bodywork cleaner.
  • Scratch cleaner.
  • Abrasive polish.
  • Fine abrasive composition.
  • Felted wheel with Velcro.
  • Sponge.
  • Soft lambskin wheels.

The polishing machine is better than other tools for working with the coating. Sometimes a drill with speed changer and angle grinder are used.

  • Circular. Looks like an angle grinder, torque is high, speed is low, so they are rarely used for car finishing.
  • With an eccentric. Make reciprocating motion with the change of position up to 2-5 mm. Safe device gives a good result, the coating does not overheat during processing.
  • Class of equipment professional or amateur determines price and performance.
  • Power. Equipment with a low index quickly overheats, pauses during work. Weak devices. 400 to 800 W.
  • Weight. Professional tools are heavy, lighter tools can do more work.
  • Disc width affects speed of service. Available in diameters: 125 mm, 150 mm, 180 mm, 240 mm.

Types of nozzles

Petal wheel

To begin, take scraps of plywood and cut out of them 9 small even circles with a hole in the center.

Next, fasten these holes to each other with glue, after which they must be aligned by connecting them to the engraver and driving them on the sandpaper.

Clamp nozzle in a vise and make eight cuts with a metal saw. In these kerf is inserted small square pieces of sandpaper with the necessary grit for your work.

Then soak the pieces in glue or epoxy and let them stick out.

At the end, put the homemade petal wheel on the engraver and test the nozzle.

The large diameter petal wheel

The assembly principle is the same as the last one, but with some details.

You still need to take scraps of plywood and cut circles, but larger.

Then staple them together and make eight cuts with a metal saw. Pieces of sandpaper are still inserted into these kerfs, but then compressed with a rubber band and soaked in glue or epoxy resin.

Allow it to harden and dry, and then start testing your homemade large-diameter petal wheel for your engraver.

Suddenly make these three nozzles (burs, bits) for the mini drill (drills, Dremel):

The multi-blade sandpaper brush (“daisy”) on the left is needed for even and silky, (matte, “coarse”) sanding metal. a very useful thing in the household.Any metal surface can be renovated to a new condition with it.

As a side note, I have a drill like this:

this is a 24 volt soviet motor, long and narrow enough so that you don’t have to insert it into the handle tube, plus a Chinese collet chuck. Plus homemade regulated power supply on KREN12A.

So, first we make the simplest, but, by the way, a childhood dream. an electric file (or a rotary file):

We forge a roller out of the lighter (by spinning it we knock the sparks out of the silicon) and put it on some kind of rod. It is desirable that the rod has a thread on the end, so that the roller is tightly stuck. Done.

a video of this action and everything else, which will be described through text and photos below.

Here I want to impudently point out that all three of these tools (or rather how to make them with your own hands), I invented completely independently and made 10 years ago. But now I saw on YouTube videos the last 2 years, which people are doing the same (except “daisy”) and they have there rave Комментарии и мнения владельцев, millions of views, blackjack and whores So I’m now angry-painful gets: my videos with brilliant ideas and really useful tips and crafts Che Che not almost anyone looks, and even someone and dizlikes puts Sign Up! 1 in karma: LabaKraba (AmolonieX. here in English or no words at all).

To cut the sanding discs from a sheet of sandpaper we make a puncher (hole punch) and a circular knife:

Punch is two boards with a gap of two millimeters between them and the hole for the drill at 1.8 mm (need 2.0 mm, but in the process of making the hole will turn a little). The back end of the drill bit is sharpened to have a sharp edge.

At the end of the drill, which will be pressed, you need to put a cap under the finger through the paper to fasten it tightly.

A circular knife is simply an arbitrary iron plate with bent and sharpened ends. In the end, we have:

Very even and without interfering bent edges (which will be if you pierce with an awl) the central holes are obtained. Circular knife to cut circles quickly and fairly even.

Well, and the hit of the program. making sandpaper petal brushes.

We take the sleeve from the spool of thread. On the video the outer diameter of this tube was 12.6 mm, but it turns out that they vary greatly in diameter, and here in this picture is another, with a diameter of exactly 12.9 mm, t. е. Exactly what we need. We wind two strips of paper crosswise with glue between them and get a paper tube. the basis for the “daisy”. which we cut into sleeves (top-right in the photo).

By sticking 13 x 20 mm sandpaper blades on these bushings with strong joinery glue. And not orthogonal, as in the store sold, and how would overlap. We have:

Let’s write the granularity on several petals. Done. The petals sometimes fly off (see the photo). extreme right in the photo above), so it is better to use an emery cloth based. Plus wet the petals with soapy water before use, otherwise they will be salinized (clogged with shavings) and spoil the evenness-silky texture of the ground metal in these places.

You might notice that similar brushes (only with short blades) are sold on Aliexpress. But I remind you that I figured out how to make them (to glue the blades tangentially to the sleeve, not orthogonally) and made them 10 years ago, when there was no Aliexpress.

The video at the end shows the texture you get on the aluminum plate from using these 3 brushes of grit 40, 80, 500. The 500 is the best, it’s got that nice matte, silky texture to the touch You have to grind in one direction strictly!

Material used

Grinding pads are made of different materials. You have to choose them depending on the surface to be machined and the work to be done. For example, to remove rust and paint, you will need a hard nozzle, for polishing. soft.

  • Soft. They are used to remove primer and filler, rust marks, and for polishing and cleaning dirt. Thanks to the soft action, metal is not heated and does not deteriorate during operation, which improves the quality of grinding.
  • Sanding cloth. The most popular attachment on the drill for sanding wood. It is differentiated by grit size and roughness, which allows using it for different types of work. from rough cleaning of the surface to finishing of details.
  • Grinding stones. These are special abrasive stones, harder and stronger. They can be used to remove defects from the surface. They are usually used for preparing and smoothing concrete, glass, ceramics.

When choosing, it is important to focus not only on the material, but also on its hardness and grit size. Felt, for example, can be used to polish a car.

When working, it is important to hold the sanding pad on the drill for wood with respect to the surface. For example, if the plate nozzle is not positioned at a right angle, its edges will easily spoil the surface. To understand the principle of operation, it is worth practicing in advance how to hold the tool correctly.

  • The operator holds the drill in his hand and works as with a conventional tool. This is the simpler and more familiar method, but it has disadvantages. Holding the drill for a long time can be tiring. In addition, it is important to watch its position and not to tilt. This way grind large surfaces: walls, floor, ceiling, large furniture, car.
  • The drill is fixed on the table stationary, and the object is brought to it. You can achieve a high quality of sanding with this method, but it can only be used on small objects that you can hold in your hands.

Tool bit types

Drill bits come in several types, each of which is used for clearly delineated work. The size, shape and characteristics of these components differ. Let’s take for consideration the main types of grinding nozzles.

Disk

A very popular type, which is a construction of some amount of sanding material arranged in a circle. Different material is used. Thick steel wire is used for hard metal surfaces. Use polishers for final grinding and polishing.

Disk nozzles are able to work not only on the surface, but also on the edge, which allows you to polish narrow recesses. Greatly suited for complex workpieces. By design, such nozzles slightly resemble cup ones. But the difference is that all the bristles are based on a circular disc in the middle.

The use of such tools requires certain skills from the master, so before performing responsible work it is better to practice as much as possible.

Cup-shaped

The sanding drill bit, which consists of a cup-like base and multiple fibers of sanding material. Used for removing paint or varnish from the surface of the piece. For wood is also used as a sandpaper. There are many different types of cup nozzles, designed for different jobs. You can find a component for any task.

After using such sandpaper, it is advisable to carry out the treatment with cup nozzles. This will help highlight the structure of the wood, on which the lacquer coating can easily be applied.

Petal

Separate type, which is a set of strips of material fixed on a rotation axis. Sometimes these models are called fan models. Each petal is made of abrasive material, which helps to provide the desired impact on the object of treatment.

Very often ordinary sandpaper is used as the material. This helps to cheapen the product and make it as effective as possible. Suitable for machining wooden objects of different shapes.

Drum

Sections of sandpaper are fastened to the solid cylinder. This cylinder can be made of rubber or other material. Special retention mechanisms are used to prevent the paper from shifting off the drum.

In order for the paper to adhere tightly to the drum, it is artificially deformed and forced to increase in size. Paper is taut and securely attached to the nozzle. These models are used for processing wooden, glass or metal parts. Allow you to polish the surface to a mirror shine. Convenient to use for deburring workpieces.

Plate

Two components make up the model: a plastic disc and a sheet of abrasive material. This sheet is fastened by means of a sticky material. An important feature of such a nozzle is the presence of a damper, which will smooth out the irregularities of the material and allow you to evenly grind the surface of the part. Without this damper, the application would be severely hampered. It is hard to accurately guess the amount of force needed to sand the surface. High risk of damage to the part’s integrity. Especially for overhead work.

Any elastic material is inserted as a dampener. Simple foam rubber is inexpensive and convenient.

Work with devices requires a high level of skill of the master. It may be difficult for a beginner to maintain a straight angle to the workpiece. Sometimes you can find models with a special mechanism that allows you to adjust the angle. Can be used for both roughing and finishing. Everything will depend on the type of abrasive used.

Soft

Such components are usually used to work with sensitive surfaces that are easy to scratch. Also used for polishing mirror surfaces or lacquer coatings. Are usually made of felt, polymers, foam rubber or some woven material. There are different shapes. All depends on the processed part and its characteristics.

Abrasive

End bits, which can be used for boring holes or giving the part the desired shape. Have fairly high rigidity, allowing removal of entire layers of excess material. All parts are machined perpendicular, at right angles. This can be difficult for inexperienced craftsmen.

The heads come in different shapes: ball, cone, cylinder and more. Stones can be used for these heads. The model is widely used for sharpening tools.

What kind of jigs are there

Unlike the attachments on the angle grinder, any fixture for the drill, equipped with an axis that is fixed in the chuck.

Plate

Basically, grinding attachments for the drill are made of plastic. They are primarily designed for use in an angle grinder, but thanks to the adapter they can be attached to the tool chuck.

This attachment is rigid, so it is not applicable in all cases. For example, even with a small displacement of the nozzle, its edge can gnaw into the ground surface, leaving deep notches.

For this reason it is more convenient to use a rigid plastic nozzle by fixing the drill stationary, as in the following illustration.

convenient when working with a drill rubber nozzle. because of its flexibility excludes accidental damage to the machined surface when tilting the drill or excessive pressure on it.

Another type of similar grinding tool is made with a movable pin attachment, but because of the high cost of the latter, it is not in great demand.

Bowl Brushes

Structurally, the cup nozzles do not differ much from each other, but the brush itself can consist of metal (steel, brass) wire or polymeric abrasive fluff.

Each brush has a certain hardness and is used strictly for the intended purpose, set by the manufacturer. you can grind metal (removing traces of corrosion), wood and other materials.

Work with such a tool is fraught with some difficulties. choosing the wrong angle can spoil the soft material to be processed, and the drill itself constantly tends to move sideways when pressing the device with its entire area.

Disk

These nozzles are similar to the cup ones, but the direction of the bristles is different. to the sides. Most often they are used when you have to process material in hard-to-reach places.

Drum

This appliance resembles a drum, and thanks to this resemblance is given its eponymous name. Such a drum nozzle is a cylinder, the outer wall of which is fixed with sandpaper.

This device is attached by tensioning with a special bolt or fixed by pumping with compressed air. With an unclamped belt, tension is created by a rotating screw that tightens the sandpaper.

With drum nozzles you can easily sand wood and metal parts. Sanding pad with fine particles of abrasive material can be used for finishing edges of glass. Very convenient for grinding round and oval holes.

Fan

This nozzle is made as a disk with fixed abrasive fragments. This feature greatly extends the range of sizes of work pieces, grinding cavities of small and large holes. Thanks to the flexibility of the blades, it is possible to grind workpieces of all shapes.

End cap

These nozzles have different shapes and the working part can be made of different material.

Designed for starting or finishing holes and the inside of shaped workpieces. Similar devices, only of miniature size, are used by jewelers and dentists.

Soft

When polishing the workpiece, round foam, felt or leather nozzles fixed on the axle can be used. This tool wears quickly and can be used to polish metal or varnish/painted surfaces to a high luster. The attachment is matched directly to the material to be polished.

Cup-shaped

There are several versions of cup-type sanding drills. The most common ones have a metal body with a pin that can easily be inserted into a chuck. The body itself is filled with either stiff bristles of metal or light bristles of brass. Such an attachment is used for grinding metal, wood and other materials. Also often used to remove paint and corrosion marks on metal.

Another subtype of cup brush head has a padding in the form of a soft material for polishing and soft scraping. Either foam or felt or other similar material is used. The body of such tips are often made of lightweight and durable plastic. Using this type of brush head requires some practice, because it’s pretty easy to malfunction with the drill and thus damage the surface you’re working on.

Disk

Disc snappers are close relatives of the above-described cup snappers for grinding. The only difference between them is the direction of the filling or bristles. In the case of a circular brush head, the bristle runs away from the center to the edge of the disk. They also use steel wire or a soft brass brush as bristles.

The use of such tools also requires some skill and experience, because unskilled use of such devices can lead not only to damage to the material to be treated, but also to serious injury.

But sometimes they are indispensable for hard-to-reach areas and small surfaces. This type of nozzle is attached to the drill through a usual pin, which is inserted into the chuck of the tool.

Checking out a homemade disc

It flies fine dust and does not sand well. The paper is too soft. It only smoothes the workpiece. The marks from the band saw blade are still there, but a little smoothed out. It turns out that for rough sanding this blade is not suitable. Let’s try a cloth sanding pad. It is stiffer. Let’s make the length of the petals shorter, too. I also changed the profile of the template a bit. Made it already, since the petals bend when touching the workpiece.

Recently became the owner of a band saw. So making kerf cuts is much easier. Stuffed the drum with petals the same way as before.

In the meantime, the glue dried up, to get to the undried glue had to cut the tube. Checking. The effects are there. noticeable than with the previous disc, but not nearly enough. It would be quicker to remove the saw blade marks by hand. Use the petal sanding discs for finishing sanding. A negative result is also a result. Maybe you can tell us what is wrong.

For all these works, the most different nozzles are used. After considering the advantages and disadvantages of implementing such devices will be examined their main types and areas of implementation of all of them. There will also be described a few options for homemade attachments for grinding with a drill.

Should immediately direct the attention of users that the devices for grinding in the drill produced by very many manufacturers. Some make more high quality products, others are chasing after the quantity and low prices. Because choosing the same nozzle from different manufacturers can significantly different quality of the brand.

Advantages and disadvantages of grinding nozzles for the drill

The advantages of tools for dremel, used for polishing and grinding, are listed below.

Low cost allows for a small means to cope with many tasks on the grinding without the purchase of special machines and other devices. Usually even the highest quality devices have a low price in comparison with the purchase of special sanding equipment completely.

It should be noted the versatility and abundance of sanding tools for the drill. Now they are not so little that they will help to perform even the work, which are not feasible standard methods of grinding and polishing. But in this case it is worth considering that the use of some types of devices for dremel requires some skill and considerable experience.

Than two principles and convenience of implementation. Some nozzles for the drill allow you to grind, sand and polish surfaces in inaccessible places, which can not get standard means. Even today it is easy to handle small parts and products with this method.

Along with the listed advantages, grinding attachments for drills have some disadvantages. Here are some models:

For how else it is called the other work with attachments need a drill of varying size, power, and fine-tuning the number of revolutions.

In the role of such nozzles are used and others are designed for angle grinder. To be able to fasten them to a drill, used a special adapter in the form of a pin with a thread, which is usually clamped in the chuck tool. But this is not a suitable option for a drill, because the rigid attachment occasionally interferes and can spoil the entire work.

successful nozzles plate type are those made of soft material. They are mainly available in rubber. Such a material allows you to work more gently with the nozzle, without the risk of spoiling the machined surface by excessive pressure.

Rubber cup sockets have a non-moving pin for fastening to the chuck. Then a firm grip will only be beneficial. Whichever platter nozzle on the drill for grinding is not used, they all work in tandem with sandpaper, which is attached using Velcro. To this end, the market has an abrasive paper in the form of disks, with the back side occupied by a special coating of course. Regular paper is not used for such purposes.
