For today’s post I thought I’d show one of the detail shots I took while at the Ayer Mill clock tower.  These gears are part of the clock mechanism, and help control the movement of the hands on one of the clock faces.

These gears are maybe 12 inches in diameter, yet they’re partially responsible for moving the enormous hands on a 22 foot clock.   Fascinating.

    WHo could have thought that this could move something 22 times in its size
