How to make sandpaper yourself? Emery emery with own hands (drawings)

Quite often, domestic craftsmen experienceneed for the use of emery. It may be required when blades or scissors are blunt, as well as other cutting tools that require sharpening from time to time. Many specialists are not in a hurry to acquire such equipment because it is very expensive. There is no need to talk about private consumers who use such equipment less often than professional masters.

Self-made emery

Emery paper can be made by hand, if youyou have the engine from the old home appliances, you can apply it to the case. First, you need to choose an electric motor that would be suitable for manufacturing the described equipment. Quite often for the design use engines from old washing machines such as "Vyatka", "Volga" or "Siberia". This technique has a fairly powerful motor.sandpaper

Among other things, the washing machine canborrow a switch that has a starter. Despite the fact that the carrying out of these works may seem quite simple, it is very difficult to manufacture sandpaper by oneself. For example, as one of the main questions is how the grinding stone can be planted on the motor shaft. This is due to the fact that there is not always a thread. In addition, the diameter of the hole of the stone may not coincide with the diameter of the shaft. For this reason, you need to prepare a special sharpened part.

Defining parameters

In order to make an emery with your own hands,you must first determine its parameters. Quite often, asynchronous motors are used to make such an installation at home. For the emery, you can apply the maximum ripple, which is 3000 rpm. If you use a more impressive rotation speed, you can face the problem of breaking the grindstone. Preferably at home use a motor that has a speed in the range of 1000-1500. If you use an electric motor at 3000 rpm, you need to prepare a sufficiently strong stone. Among other things, you will need a quality flange. Most often, large engine speed is not used to grind, but to polish parts.how to make emery yourself

In order to make the emery by hand,It is not necessary to use a powerful electric motor. For a homemade grindstone, the more acceptable power is the limit of 100-200 watts. Three-phase and single-phase electric motors can be used.

Preparing the flange

Before you do the emery yourself, you need tothink about how to ensure the connection of the engine with the stone. For this purpose, a flange is prepared. In carrying out this type of work, it is preferable to use the services of a turner. But the rest is already a matter of technology and the question of having available materials. It is necessary to prepare a flange, which is mounted on the shaft, and also strengthened by the washer. It should be noted that on the nut and flange, the thread must be prepared depending on the direction of rotation of the motor shaft.emery drawing

If you make the emery yourself, the drawingswhich is to be considered before the work starts, you will use a system in which the rotation is clockwise, then the left-hand thread must be prepared and vice versa. If this factor is not taken into account, then the nut will work on unwinding. This will certainly lead to the fact that the stone can fly away. If there are no suitable equipment for making bushings of a certain diameter, pipe pieces can be used, and the resulting clearance between the shaft and the motor bushings must be compensated by a twist of the electrical tape. You should choose the one that has a tissue base. It is necessary to put the sleeves one on top of the other. In this case, winding the tape, you need to observe uniformity.

Council of the master

Making emery by hand from washingmachine, the bushing needs to be made using a pipe, the diameter of which is 32 millimeters. On it it is necessary to put on an emery circle. Such a system of bushings will be strengthened firmly on the shaft.

Recommendations of a specialist

If the work is done at home,then you can prepare the thread with a tap, and you will need to grip the motor shaft in a vice. Before you make the emery, you need to determine the direction of its work. It is very important.emery from the washing machine

In the emery, made by own hands, it is possiblecorrect the direction of rotation of the rotor. It will be necessary to find the starting and working winding using a tester. The resistance level of the winding is quite often equal to 12 ohms, but the starting point is close to 30. The working winding should be connected to the 220 volt network, but the starting winding should be connected at one end to the coil terminal, while the other should touch the second winding terminal, him.

Features of the tool making

Emery electric with their hands quite oftenis manufactured at home without the use of a starting coil. In this case, after turning the winding into the network, it is necessary to start the abrasive stone in a certain direction with the help of hands, after which the machine will work independently.

Carrying out the emery installation

Let's look at how to make emery fromwashing machine with their own hands. First you need to determine how to properly install it on the workbench. This can be done using a bracket, which is removed from the washing machine. The fastening can be done with the help of bolts. The motor on the other hand rests on the angle that holds it in a horizontal position. Among other things, it has a cutout that completely repeats the outline of the motor housing.emery electric with own hands

In order to reduce the vibration force, the angleIt is necessary to wear a bezel made of a rubber piece of hose. Avoid getting injuries from running saws and flying debris of the abrasive wheel when using the machine can be a method of manufacturing the casing. It is preferable to make it out of steel. Choose for this you need a canvas, the thickness of which is 2.5 millimeters. It can be a strip of metal, which needs to be folded in the shape of a half-ring. Under the emery surface, it will be necessary to mount a sheet galvanized element, which will protect the workbench from the effects of flying sparks that form during operation. All actions for your own safety should be done with the help of special glasses.

Finally

As equipment adaptations, you canApply plexiglass, the thickness of which should be equal to 5 millimeters. It is strengthened on the engine casing, while it is necessary to use a sample. Fastenings should be carried out in such a way that it is possible to bring the element backwards 180 degrees.emery from a washing machine with your own hands

You also need to make a pod, which is necessaryFor a durable and reliable workpiece rest. All the work can be done independently, without resorting to the help of a master. To do this, you will need to stock up with the appropriate tool and material. In addition, there is no way to do without the recommendations that were presented in the article.
