I just verified that the inner cam and the outer cam do not revovle
together all the time. It takes a number of revolutions of the
inner
cam to move the outer cam a knob forward.

My previous description maybe incomplete. Here are some hard numbers:
The inner cam which is turned by the timer motor through several sets
of reduction gears is turning at 1 revolution per minute. The outer
cam which turns with the timer knob via an anxle has 60 notches and
every 15 seconds, a notch is moved forward, so it works out to be 15
minuters for a revolution for the outer cam. This is recorded when
feeding the timer motor with a black box simulating 230v and 50 hz.

Now, when running on 60 Hz, is everything just 6/5ths as fast?
