2016-2-13im just getting ready to fit a vfd to my surface grinderhe native speed at 50hz is about 2900rpm have a stack of 6" wheels which have a higher speed rating so i can fit a pot to control the spindle speed and my idea is to surface mount it somewhere prominent and make a scale that reads in rpm, but is it realistically going to be useful or an unnecessary complication.
