That is a very nice set up Gary, but due to my health and retirement I no
longer can get my hands on a Bridgeport to make the holder for the propeller
, but I do have the rods both in 5/32 and 3/16. I would gladly trade some
rods or other things for a extra block. I do have a phenolic?? disk with a
1/2 dia hole in the center and 6, 1/4" holes on the circumference  I was
going to use as a start. I made it several years ago and has been on a
shelf. I brought up the Kva because my RQ copper tube gap worked fine for
the NST coil but my new transformer is a little much for the copper tubes.

The power needed for an RSG motor is dependant only on the mass, or more
accurately, the rotational inertia, of the rotating disk.  The KVA of the
coil is irrelevant.

I've always been bewildered by folks using HUGE motors on small coils.  From
a purely aesthetic perspective, it seems silly to have the RSG motor
consuming a significant portion of the total power.

For NST-powered coils, a propeller gap is adequate to handle the power and
is much easier to build.  If you are leaning towards a sync RSG, you want
either 1800 or 3600 (preferred) RPM.  With a propeller gap, you can use as
small a motor as you can find, as the rotor is just a single welding rod.
My SRSG may be seen at http://www.laushaus.com/tesla/sync_gap.htm.
