Homemade grinder from improvised tools

Sometimes when performing repair or construction work, a situation arises when the equipment fails and it is not possible to buy new or repair it. In this case, the master needs to know how to make the necessary tool from the available tools at a low cost. In this article we will look at how to make a grinder with your own hands.

Bulgarian from a drill

In case of failure of the angle grinder (angle grinder or grinder), it can be made from a drill. It should be noted that there are several ways to convert one tool to another. The least expensive and not so time consuming will be the use of a special device - an adapter.

The adapter is an adapter that is made in the form of stock. On the one hand, it can be clamped into the drill chuck, and a cutting disc is fixed to the other side with the help of washers.

If it is not possible to buy an adapter, you can make out with your own hands a faulty angle grinder and dismantle spindle.

You can also buy it at a repair shop or turn an adapter on a machine from a friend's turner. Holding the adapter in the drill chuck, we get a workable angle grinder.

TO design flaws can be attributed to the fact that this "grinder" can only be used with strict adherence to safety regulations. She can cut metal no thicker than 5 mm. In addition, since the speed of rotation of the shaft of the drill is significantly lower than that of angle grinders (3,000 versus 11,000 revolutions per minute), the metal processing efficiency is much lower in this case.

TO advantages Such modernization can be attributed to:

• fast conversion of one device to another;
• use of the tool in places inaccessible for factory-made angle grinders.

When using the drill as a cutting device, it must be borne in mind that the shaft of the drill has a rotation in both directions. Therefore, when cutting metal or other works, it is necessary to follow the direction of rotation. The blade should rotate only clockwise.

There is another way to rework.But it is more costly, for its implementation acquire a special nozzle, which has a gearbox. A native gearbox is dismantled on the drill, and a nozzle is installed in its place. As a result, a good grinder from a drill is obtained - an almost complete analog of a faulty tool.

However, the cost of such a nozzle is quite high, and the upgrade takes a long time. Therefore, it is better to immediately purchase inexpensive angle grinders.

All presented options are intended only for emergency solutions. If it is required to use the drill for the intended purpose later, it will be necessary to spend a lot of time on its restoration.

Conversion of chainsaws in the angle grinder

Sometimes it becomes necessary to cut off a pipe or professional sheet in a place where there is no electricity. For this, a grinder from a chainsaw is used, which is easily converted using purchasing set-top box.

It consists of:

• driving pulley or drum;
• protective casing;
• belt drive and a set of keys and studs.

To install this device on a chainsaw:

• dismantle the tire with the chain;
• release the oil tank and remove the clutch drum;
• mount the pulley of the device on the drive shaft of the drive sprocket;
• fasten the safety device and install the belt drive;
• put the 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, you must be extremely careful, as the chainsaw has a higher torque than the standard angle grinder. In this case, the risk of destruction of the cutting disc increases.

Screwdriver upgrade

If you do not have a drill or a chainsaw at hand, and you need to cut materials, you can make a grinder from a screwdriver. The algorithm of its modernization is almost the same as in the manufacture of angle grinders from a drill. The main element of the design will be acquired adapter - adapter or spindle faulty angle grinder.

TO advantages Such power tools can be attributed to the rapid transformation of the mechanism and the ability to use away from the electrical network. Homemade can be used in cramped conditions, where the standard LBM is not suitable because of the large size.

Main disadvantages self-made device can be called:

• small battery life (when using a cordless screwdriver);
• low speed of rotation of the cutting disk - about 700 revolutions per minute;
• insufficient power electrical equipment.

Such a mechanism can only be used as a low-power angle grinder. With it, you can cut a metal with a thickness of no more than 1.5 mm or a corner of 20 * 20. They can cut rebar with a diameter of less than 8 mm. Use a screwdriver as a full cutting tool will not work.

Mini Bulgarian from improvised means

Such a device is suitable for those who engaged in modeling - they often have to cut parts from hard materials. It is impossible to use standard angle grinders in this case: it is necessary to cut very small elements. For such work it is necessary to make a mini-grinder. It is made of small electric motor. It may be from a faulty video recorder, printer, or children's toy. This device is powered by a cell phone charging unit, a USB input, a battery or several batteries.

The most difficult thing is making it yourself cutting element. The disk is made of the thinnest cutting wheel. The diameter is chosen independently, according to the conditions of use.

Sometimes the cutting wheel is made from ordinary cork from drinks.

The manufacture of the device begins with the handle processing - the engine is fixed on it. Axle mounted collet clamp. Take the prepared circle, fix it with washers on the screw M6. It turns out a kind of nozzle, which is fastened with a collet clamp.

The tool is ready to work. The mechanism of the motor can be used without a handle, if you want to trim the parts inside the model.

How to make a device, you can see in this video:

Anyone wishing to make a device should be aware that the homemade Bulgarian does not respond safety requirements. If there is no urgent need, it is better not to risk your health, and sometimes life.
