I admire the ingenuity of craftsmen constructing power tools out of wood. The very first metal lathe was made out of wood and stone, Mills, Drill presses, Band saws, Table saws, the list of tools made from wood is endless.
As long as care is taken they can be made as safe and those made out of any other materials.
I have to side with nova_robotics about the possibility of dust catching fire though.
That said It is an nice quality build.
