Sorry, no etymologies found.
As the 'runner stone' rotates parallel to the stationary bedstone, the grain is crushed.
It consists of a perpendicular shaft, to the lower end of which an horizontal wheel of about four or five feet diameter is attached, the upper end passes through the bedstone and carries the runner after the manner of a trundlehead.
This causes an intense laser beam to hit the bedstone directly where the forehead of a sacrificial victim would normally lie.
