Unfortunately, no guidance was discoverable for building. If you proceed logically and has as a part ever seen but it should not be a problem to build it. Commissioning is then relatively easy to explain, since there is only one on-off switch, no control options. The grinder performs its function very well and grinds metal properly. Through the two disks, you can choose whether you like something or fine grinding it wants down quickly (coarse). There are hardly bigger determine vibrations during operation. However, you should always wear a safety for eyes and ears during operation!
For the small price, and if you want to use the instrument only every now and then I can recommend it only. For higher demands on processing quality and functionality you have to shell out more.
