I think that is a fantastic idea !! If we take this one step further and
mount the two sets of stationary electrodes on two disks (for a
grand total of 4 disks--- 2x running, 2x static). All four disks are
mounted on a common (driven) shaft. However only the two
disks containing the rotating electrodes are "clamped" to the shaft.
The two stationary disks are mounted on ball bearings, so that they
remain stationary when the motor is running. The two stationary
disks get some sort of lever (maybe a threaded rod and a clamp
nut, etc) which is attached to two control motors (DC). You can
now control the phasing of both RSGs separately with the touch
of a button. You could even add limit switches (4 needed) that
would automatically reverse the DC motors, once you have reached
the maximum phase change possible. That way you can "cycle"
through the phase. With such a setup you should be able to get
rid of all phasing problems and (as you can control both RSGs
independently) be of help in adjusting twin coils for maximum
spark length. This just might be what Lou is (was?) looking for.
