[GreenKeys] Free Main Shaft and Motor

[Brooke Clarke]

Hi Derek:

The holes in the disk are all at the same radius so it's not a flying 
spot scanner.
There appears to be an optical source/sensor across the holes which 
would allow this device to generate something like a square wave.
How many holes and what's the RPM of the motor?  Can you see a part 
number on the optical source/sensor?

To free up the mainshaft Kroil may work.

Have Fun,

Brooke Clarke
