Alan -

  The ring actually sits on the toroid, kinda towards the middle
laterally. Obviously, if you make the ring too large, it won't stay
on...I hope to take pictures once I: (1) get the high-velocity blower
up and going -- found a nifty 28-volt DC blower that originally provided
ventilation for the Apollo mission astronaut suits!!!, and (2) whenever
the rain goes away outside.
