Michael,

For using a non-sync rotary with an NST, the precautions would
include using a R/C filter network with MOV's such as
Terry uses, and keeping the safety gap somewhat narrow, and
accepting safety gap firing at certain lower break rates.  I know
that some folks have done this, and their NST's are still working.
I don't know how long it can last, possibly quite long.  I've never
tried the protective methods myself, and my NST was carbon-
tracked when I ran it in non-sync mode.  I always use sync
rotaries now with NST's
