Try 3 to 5 MFD and make sure it is not staring under load, once it spins up
to speed close the coolant valve . Be carefull not to allow too much back
pressure so that it slows the pump down. You will need to leave the
capacitor online.

I'm rebuilding a hardinge CHNC...

The machine will be single phase with a VFD for the spindle.

I just found out the coolant pump is three phase. It is 1/10 or 1/20 hp.
Using a clamp type ampmeter it just tickles the needle on the 6 amp full
scale setting. I'll guess .1 to .2 amp per phase.

So, would it work to just use a run cap accross L1 L2 L2=wild legto
start this thing? How large should I try?

If needed, I could use a start delay timer and bring in a cap accross L2
L3. Need this? How large?
