How to make a sander from an angle grinder?

Such a question can be confusing, because an angle grinder is an angle grinder. But it is very versatile and must be prepared for each operation. To prepare the angle grinder for grinding, you need to purchase a support wheel that fits directly onto the machine shaft.

To process wood, you need to glue an emery cloth on this circle. The number of sandpaper is selected for the immediate moment of work. On sale you can find both a grinding wheel of the required diameter and emery wheels of the appropriate size. Velcro emery wheels are also commercially available, which are very easy and quick to change on the tool.

To convert our angle grinder to concrete grinder, it would be a good decision to purchase a special dust cover. It is good because it has a branch pipe for connecting a vacuum cleaner. Known casings are produced by Hilti. On the cover of this company there is a sliding sector that opens part of the wheel for grinding in the corners.

Grinding metal angle grinder is usually done with standard metal grinding wheels. They have different diameters, different thicknesses and different grains of the grinding surface. But, if you are going to grind an indecently rusted surface, then first you need to brush it over the metal. Such brushes of the required diameters are also on sale.

We work on concrete

If it was not possible to purchase a branded protective dust cover with a nozzle for a vacuum cleaner, then you can do it yourself. To do this, take a used bucket from under putty or glue with a diameter slightly larger than the circle of an angle grinder. We cut off the bottom part at a height slightly larger than the assembled sanding part.

We cut a hole in the bottom for installation on a gearbox and a hole for a plastic plumbing corner bend. Now we connect the vacuum cleaner hose to the nozzle and work calmly.

The grinding wheel must be suitable for stone processing. Concrete and concrete surfaces are preferably sanded with the entire surface of the wheel. This will save machining time and level the surface well.

When sanding a concrete floor, it is necessary to constantly monitor the plane with a construction ruler, because, due to the different density of concrete, indentations can be made. For the processing of butt joints between concrete fillings, it will be sufficient to achieve one level combination.

Grinding wood

Wood is a unique material. It can be sanded by hand quite well, but with an angle grinder you can achieve very good results. Some snobs argue that you can’t grind an angle grinder at all, but this is due to ignorance and inability.

The main secret of the grinder is used at minimum speed. If the angle grinder has a speed switch, then there will be no problem. At high speeds, the sandpaper will clog very quickly and very tightly with wood. In this mode, it will not be enough for five minutes of work. The optimum speed is no more than 6000 rpm.

Another secret is not to sand the entire wheel area. If you sand the entire surface, then circular marks will remain on the wood. So that no traces of sandpaper remain at all or they would be minimal, it is necessary to grind only with the upper sector of the circle. The movement of the machine should be along the grain of the wood.

With this method, you can get excellent results when sanding the lining. The board becomes smooth and does not retain tool marks. Do not just get carried away and change the emery pads on the circle in time.

The frame is polished in a similar way. Here, it is desirable that the support plate is thin at the edge. With such a plate, it will be easier to sand narrow joints of logs. Otherwise, this work will have to be finished with a chisel.

Remember that sanding is always associated with a lot of dust. Do not forget about yourself when preparing for sanding! A face shield and a respirator are the best helpers for grinding. You can also find an option where the mask is combined with a good respirator.

The respirator filter will clog up very quickly, so you need to prepare several pieces at once for quick replacement. Only after thorough preparatory work can you start grinding.

The subtleties of flawless hand sanding

Dry or wet sanding?

For intermediate sanding of finishing coats of wood stain, varnish, polyurethane, etc. Traditionally two techniques are used, dry or wet.

Dry grinding increases the efficiency of the abrasive and makes it possible to better control the process of work, which is especially important at the stages of intermediate grinding of delicate coatings. The disadvantage of this technique is the rapid clogging of the skin. Partly this problem is compensated by sandpaper with an anti-clogging stearate coating.

When wet grinding for wooden products, mineral oil, white spirit or ordinary soapy water are used as a moisturizer. Abrasive with this technology clogs up much more slowly and, accordingly, lasts longer. But the mess from foam and chips makes the sanding process much more difficult. It becomes necessary to constantly wipe the surface and carefully monitor the result of grinding.

About sanding pads and making them yourself

Sanding pads (grinding) are irreplaceable assistant in the arsenal of the joiner. These simple devices ensure uniform contact of the sanding paper with the surface being processed, increasing the speed and quality of the work performed. Using such pads, you will significantly improve the quality of grinding, extend the life of the abrasive, and avoid irreparable defects in the form of grooves and rounded ends.

There is no need to spend extra money to acquire such a grinding tool. It will not be difficult to make it with your own hands from dense foam or wooden scraps. Check out a few simple sanding pad designs in our gallery.

What are the benefits of hand grinding?

Sanding wood by hand, although it requires a lot of labor, in return provides a number of important advantages: less aggressive processing, better control over the process and high quality surface treatment in hard-to-reach places in corners, on smooth bends and other reliefs of any complexity.

Manual technique is indispensable for interlayer sanding of finishing coatings, since it provides the most delicate work and eliminates the risk of rubbing the applied finish. When using the same abrasive, hand sanding guarantees a better surface finish than sanding with a sander, angle grinder or drill.

Surface Grinding & Angle Grinder (Angle Grinder)

Angle grinder (angle grinder) is a multifunctional device that is also used in the situation under consideration. For this, special circles are used. Petal circles are made from sandpaper, which is attached to a flat surface. The circle can be of different diameters, with different grain size. When choosing, the following recommendations can be highlighted:

  1. To remove paint, take a coarse-grained circle;
  2. If it is necessary to remove a thin layer of wood, you can take an abrasive that has an average grain size;
  3. In order to give the wood a special smoothness, you can use a fine-grained abrasive.

However, it should be noted that the removal of the surface will not be carried out along the fibers. At the same time, it is almost impossible to regulate the rotation speed and feed. You can use an angle grinder when there is no need for a high performance indicator.

In order to carry out the grinding of wood, you can use special equipment, which is called a surface grinder. The features of this include:

  1. The wood is combed by the reciprocating motion of the abrasive material.
  2. The sandpaper moves at a high speed, which allows you to achieve good results when working.
  3. Unlike other methods, in this case the grinder carries out processing along the grain, which determines the high quality of the product.

The design is quite simple, it allows you to achieve good quality. But when changing large surfaces, the grinder has little efficiency. Certain models have a rather large surface to which the skin is attached, but it is quite difficult to provide the necessary force in this case.

How and how to grind wood

When carrying out various types of repairs, at the time of production of furniture or wooden items, it is often necessary to sand the wood. There are quite a few methods that can be used to sand wood. They have their own advantages and disadvantages, some involve the use of a hand tool.

You can sand wood:

  1. When using an angle grinder, you can bring the condition of the tree to the required state. An angle grinder has an abrasive material represented by a circle;
  2. A conventional drill can also be used to bring the surface of the tree to the desired state;
  3. A surface sander can become the main structure in order to sand wood;
  4. Belt sanders are used for sanding wood with an abrasive material;
  5. It is also possible to perform sanding using hand tools.

Despite the fact that the natural material in question has a fairly high structural hardness, quite a few grinding methods can be used, some of which we will talk about in more detail.

Belt sander

The belt sander is the most productive tool that can be used for processing wood with high productivity. The jetting technique also has high productivity.

DeWalt Belt Sander

The work of the structure is carried out using a circular sanding belt, which can have various degrees of grain. The design removes the material along the fibers. However, do not forget that you cannot grind the corners with this design. The tape can be used for a large amount of work: floor, walls, furniture, and so on.

Despite the great automation of work, it is possible to provide mechanical action by a manual method. This is due to the fact that the removal of fibers can be carried out in the desired direction. It is also possible to carry out corner processing. However, in order to achieve the desired result, you need to have certain skills. The work is very difficult and time consuming. Therefore, hand tools are very popular only in certain cases.

What is the best way to grind wood with an angle grinder or a sander?

Wood the most environmentally friendly, and therefore the most popular material for construction and decoration. The appearance of the finished product largely depends on the quality of its grinding. You can handle a wooden surface by hand, but it is easier to use an angle grinder or a special grinder for this. Let’s take a look at the pros and cons of each of these tools to see which one is best for removing the surface layer from wood.

Sander

This is a professional tool that allows you to handle large surfaces with high quality during finishing. The principle of operation is that sandpaper is fixed to the base of the sole varying degrees of abrasiveness.

When the device is turned on, the sole is set in motion due to this and the surface is sanded. Grinding machines are:

  • Eccentric. They can be used for polishing parquet and even car bodies. With their help, you can very delicately and extremely accurately grind a wooden surface, with the exception of corners and shallow recesses where the disc cannot reach.
  • Vibration grinders. They can process not only wood, but also plastic and stone surfaces due to the possibility of speed control. It has a rectangular sole, ideal for large areas.
  • Delta grinding. The triangle-shaped sole allows for precise finishing of corners and edges.
  • Multifunctional. This type of tool can be used both for large volumes of work and for processing hard-to-reach areas and corners. Additional attachments to the sole in the form of an iron allow you to sand even a profile.

There are also belt polishers for roughing and polishing machines to give the surface an absolute smoothness.

What is an angle grinder

Angle grinder is colloquially called angle grinder. The instrument first appeared in the Soviet Union in the seventies of the last century. It was imported from Bulgaria, hence the everyday name of the device. It is used in construction, wood and metal processing. The tool motor axes are at right angles to each other, the body is cylindrical, the handle is most often on the side.

For material processing, the angle grinder is used abrasive wheels of different thickness, which are attached to the shaft. Most often, angle grinders are used to cut metal, tiles, bricks, ceramics, concrete, granite. Flap discs are used for surface grinding.
