I cut the previous posts off, hope you don't mind.
Your motor name plate indicates 1780 rpm?
Then it is an 1800 motor with a "slip factor" counted.
If it were me, I would have the rotor machined with flats on two sides
to "lock" the motor
to 1800 rpm and run a synchronous gap. I have heard this can be
accomplished with a side grinder.
Now you can build a phase adjuster with a small variac and an
experimentally valued capacitor.
I built my phase adjuster with a 400 hz variac because i had one, and it
works just fine.
The main problem that I have had with the synchronous gap is blowing up
capacitors,
and almost destroying my nst because I ran it exactly at resonance.
