Early History Through 1875

The first illustrations (1270 A.D.) show a four- bladed mill mounted on a central post (thus, a postmill) which was already fairly technologically advanced relative to the Persian mills. These mills used wooden cog-and-ring gears to translate the motion of the horizontal shaft to vertical movement to turn a

Methods to Minimize Gear Backlash

1-3-2002Gear designs can be modified in several ways to cut backlash. Some methods adjust the gears to a set tooth clearance during initial assembly. With this approach, backlash eventually increases due to wear, which requires readjustment. Other designs use springs to hold meshing gears at a constant backlash level throughout their service life.

The Art of the Millstones, How They Work

Millstones are better because the stones want to keep themselves cool the heat generated on the two grinding surfaces works it way to the cooler surfaces of the stone and is lost to the air. When the stones run out of grain they can over heat and crack and the gears over speed and the mill gets away from you and the gears tear themselves apart.
