With a pencil and a protractor, divide the larger disc into 30-degree wedges to create 12 center lines for the bottle indents. Center and trace the smaller disc on top of the larger disc. Next, with a drill press, drill 3/8-in.-deep holes on the 12 center lines with the 1-7/8-in. Forstner bit, spacing them between the disc’s outer edge and the traced circle. Next, divide the smaller disc into 60-degree wedges and drill six more 3/8-in.-deep holes with the Forstner bit.
The progenitors of Chinese woodworking are considered to be Lu Ban (魯班) and his wife Lady Yun, from the Spring and Autumn period (771 to 476 BC). Lu Ban is said to have introduced the plane, chalk-line, and other tools to China. His teachings were supposedly left behind in the book Lu Ban Jing (魯班經, "Manuscript of Lu Ban"). Despite this, it is believed that the text was written some 1500 years after his death. This book is filled largely with descriptions of dimensions for use in building various items such as flower pots, tables, altars, etc., and also contains extensive instructions concerning Feng Shui. It mentions almost nothing of the intricate glue-less and nail-less joinery for which Chinese furniture was so famous.
