Idea

Grade 5 of 5

The joinery products used for grinding various tools. Depending on the situation sanded using hand tool or by means of electric grinders.

Of course, the tool greatly simplifies and accelerates the grinding process, so it was very widespread among both professionals as well as amateurs.

The author's idea, through which it is possible to use a drill as grinders, seemed to me very interesting and promising. So I put 5 points.

Design

Evaluation 3 of 5

The design of the grinding machine, proposed by the author, is extremely simple. As a basis he took a small diameter section of pipe and welded threaded bolt it to the outside.

At the other end of the tube two narrow holes were sawn into which is inserted a segment of sandpaper. After that, the paper curls around the pipe, grinder and ready to work.

The first thing I did not like the design, it was the absence of fasteners sandpaper. Because she does not enshrined in the proposed instrument with his own handsThere is a strong likelihood that the paper can fall out during operation, which can lead to injury.

Absence of dust collection bag will not allow long to work this device and significantly worsen working conditions.

The tool has a cylindrical shape of small diameter, so it can be used only for polishing of curved elements or holes. In my opinion, this fact strongly restrict the use of the tool. So I put only 3 points.
