I have benn running some quicky experiments vis-a-vis power
requirements for water pumps. We have mentioned the dsirability
of a DC motor so we could measure volta and amps for watts.
Actually one of those 2+ horsepower routers with a series
wound brush type motor is perfectly suited to operation
on DC probably limit the voltage a bit because of lower
resistance withot the inductive resistance when not on AC.
Some quick tests on some of my disk griders show very
satisfactory operation on rectified AC with a variac for
voltage change - Vance

I am about to run your water pump dyno this weekend Vance.
I need to remove the pump for the test dyno test engine.

I will transfer the flow meter and the pressure gauges to
the dyno engine so we can see what kind of pressure drops and flows
we are getting throughout a real rotary engine cooling system.

BTW do you have an automotive shock absorbers lying around I can use
on the dyno to damp torque vibration?
