1. If the trigger is not on it will not fire the gap. I think it would be
hard on the caps and you better have a good safety gap. You could start it
sooner but I don't see y you would want to do that. I just have the TG
attached to the input to my NST so they start at the same time.
2. I do. The case to my dimmer is grounded. The TG has MOVs to ground and
the knob is 1/2 in plastic.
3. What do you mean? Yes the dimmer is necessary. I don't have any resistors
in my configuration and it works ok. misfires once in a while.
4. The bigger the cap the more powered it draws through the dimmer. It just
adds extra stress to the system in my opinion.
The above opinions are just that. They are not based on any research.

A few questions about triggered gaps:

1. Does the triggered gap have to be powered up at exactly the same time as
the coil?
2. Did anyone ever decide if it was safe to operate the dimmer while the
coil was running
3. Is the control circuit for the gap absolutely necessary/does it increase
performance?
4. I saw Mark's gap b/f the big discussion on the list and I saw the
original diagram with a 12 uf cap (Or something around there) so I got a
motor run capacitor rated at 15 uf, now people are saying to use something
around 2 or 3 uf, will my large size be a problem?


-----------Not related to triggered gaps-----------

I have seen people recommend putting safety gaps across the transformer, the
capacitor, on the nst protection circuit, all over the place. Is there any
disadvantage to having a large number of safety gaps, or are the two in the
nst protection circuit all you need?
I have all of the parts from digikey that terry has on his circuit, but I
can't seem to find the safety gap parts, Where do you get the standoffs?, I
am assuming that the other part is just a bolt with an acorn nut on the end,
please correct me if I am wrong.


Thanks,

CJ
