Board cut, trimmed. After that, it burned to the appropriate symbols. Worth to remember that the edges need to retreat far enough, what would not create inconvenience for the session. Harvesting rubbed with wax, then covered with a uniform layer of varnish, so that there were no bruises, and the surface was smooth.
Slider, just made of any tree can be of various shapes. For added convenience, the slider has two pointers. The main (arrow) and central (hole in the center). This simplifies the job, as it allows the thumb to make way for a smaller board. The arrow indicates the top two rows of characters, and a pointer to the lower center.
On the board should also be drawn with a semi-circle. In his slider and placed before the session. This is the starting point.
