There are not two clocks you would possibly want to synch, but only one 
clock.

Its an axis with two wheels at the ends. It is very similar build to a 
turbine and most likely expensive. But just imagine a rigid shaft with 
wheels, rotating in some kind of bearings and an evacuated case.

To have the rotor free of forces (no torque).

'Gedanken' is a German word and means 'thoughts'.

Now you apparently demand from me, that I should express my thoughts a 
little clearer and leave out irrelevant details.

Well, maybe I should do that.

I had the idea of a mechanical 'add function' in the form of a laser, 
that is subsequently projected on the rim of two coupled spinning 
wheels. This is technically an add function of the modulation, since the 
modulation on wheel A adds to the modulation caused by wheel B.

These wheels have a reflecting surface with a very fine grin etched into 
it. They are at both ends of a long axis.

This entire thing is called 'rotor' and is made with great precision.

It can be spun by a motor with any desired velocity and the frequency of 
rotation could be measured.

Now the beam is influenced by rotation, if that is fast enough, since 
light needs time to move from one wheel to the other. This influence is 
measured and compared to the frequency of rotation.

If the optics is carefully adjusted to maximum reflection at standstill, 
the minimal reflection would occur, when light reflected from 'land' is 
mirrored to a 'pit' on the other wheel.

Since the number of pits is known and the frequency is measured, it is 
possible to figure out the one way speed of light.

The machine could operate more or less automatic, since all these parts 
are usual devices in industrial automation.
