Michael,

Can you explain your theory for why a high break rate is needed
(or better) for a magnifier?  A sync rotary gap does not need to have
the phase adjusted everytime the motor starts if you use the right
type of sync motor (salient pole, hysteresis, and maybe others, are 
the right type).  A sync rotary gap does not have to be complex or
expensive.  You can modify a cheap induction motor for sync
operation.  Induction motors can be gotten from old washing machines,
dryers, or from hamfests, etc.

I've never used a true air blast type gap, so I can't help there.
