NAGEL – ROUGHNESS

The connection of the wooden parts to the round plug pins is one of the most common. However, smoothly-planed rod is sometimes very poorly kept in the hole due to insufficient adhesion of the glue. Therefore, it is highly desirable that the surface of the dowel was rough. The easiest way to do this is a homemade tool that consists of four riveted together, saw blade paintings. If you roll the dowel on the bench, holding him like this “rasp”, then the surface of it after two or three movements will acquire the desired roughness.
