They could be significant with a heavy chuck swinging a big chunk of metal, back gears and feed gears engaged... Looking through the old catalogs for Atlas, Logan and Delta Rockwell you will see capacitor start motors recommended for lathes and even drill presses. Both Atlas and Delta listed split phase motors but I have never seen one recommended for any of their machines. I have not done an exhaustive search so there may be something lurking out there that I missed. Split phase motors typically don't like frequent starts, this may be why they aren't recommended for drill presses.
OK, good info. I guess I'll pass on split phase motors.
