One of the important components of self-made sandpaper is a flange adapter. It can be made on a lathe. What is needed for this?

  1. Make a sketch.
  2. Mark the dimensions of the diameter of the motor shaft.
  3. Diameter of the internal hole of the grinding stone.

With regard to the manufacture of the flange, it can be done separately or directly on the adapter. Depending on the direction of the shaft, the direction of threading should be chosen. If the shaft moves clockwise, then the thread is left, and exactly the opposite. In this case, the nut in the process of sandpaper will twist arbitrarily. And this, in turn, will make sandpaper operation safe.

What if there is no suitable cylindrical material for the adapter sleeves? In this case, take a thick-walled tube. The gap between the sleeve and the engine can be filled with woven tape. However, this option is not the most reliable.

To avoid the need to reel, you can use a metal pipe with an outer diameter of 32 mm. She is dressed quite simply and safely.

So, you can use the engine from the washing machine "Vyatka", "Riga", etc. These and similar engines have sufficient power. You will also need to take from such devices and starter.

The recommended number of revolutions for emery 1000-1500 per minute. If the turnover exceeds 3 thousand, then this can lead to a rupture of the circle. The higher the engine power, the stronger the emery wheel, as well as the mount for it.

As far as power is concerned, 100 or 200W will suffice. If you need to sharpen large parts, the engine can reach power up to 400 watts.

The emery attachment should be considered carefully. Safety of its operation directly depends on quality of fastening. Brackets are recommended for attachment to the workbench. You should also use a corner with a rubber gasket to reduce vibration. Be sure to make a protective cover that will protect your eyes and other exposed areas of the body from splintering. The casing is made of a strip of metal with a thickness of 3 mm. Cut a strip and fix it in the form of a half-ring on sandpaper.

Also note that sparks may form when sharpening metal products. To protect the workbench (especially if it is wooden) from fire, it is recommended to install a metal sheet under the bottom.

It is recommended to work on a grinding unit only in protective glasses and gloves.
