as it is opposite from the way i've seen anyone else do it. usually gaps are
put in series with eachother, to augment quenching.   i would think that an
RQ gap in parallel with a RSG wouldnt do much.  maybe it was a type-o??  Can
anyone else fill me in here?

Yes, like in Malcolm post is said, I connected the RQ gap and RSG in
PARALLEL so that the RQ gap
can catch the breaks possibly missed by the RSG. Please, note that I wrote
"I set my RQ sparkgap wide". I mean that if I order my gaps according to
their clearance, from wider to smaller, I 
have the safety gap, the RQ gap and finally the RSG. The RQ gap is
effectively a second order
"safety gap". By setting the RQ gap to a wider clearance (5 sections) from
the usual one
(3 sections) I get 3 benefits:

1. I don't have to remove it from my setup each time I use the RSG (which is
now an external
   "box" not belonging to the TC frame). I can leave it in its place and
just connect in 
   parallel the RSG.

2. I get extra protection, just in case...

3. I can easily switch from RQ gap to RSG and see the difference in a few
minutes.

Anybody yet willing/able to help me with my AC motor speed control question?
