Re: [TCML] Looking for feedback

Steve,

Did you incorporate a method for adjusting the phasing of the
sync rotary to the incoming ac phase of the power line?
Generally this is done either by  rotating the motor in its cradle 
(trial
and error until best spot is found),
or moving the fixed electrodes concentrically (not recommended),
or using my remote electronic phase shifter circuit (recommended
of course  ;^)

The gaps should be set pretty close.  I set the gaps for
my TT-42 coil at about 0.010" or so.

We recently replaced a static spark gap in our coil with a synchronous 
rotary
running at 120bps (30rpm * 4 bangs per turn). You can see a movie of 
the before
and after here:

At the moment the rotary is not delivering the performance we expected. 
I
believe this is due to a sync problem with the 60Hz supply.

Based on the movie I'd be interested to get constructive feedback from 
more
experienced coilers...

Thanks,
Steve
