I see the digital rpm readout on nearly every new lathe being made these days. I can only assume this is something that's there because of consumer demand. Well, I've turned for 35 years now, and never have had digital rpm readout......and, I don't feel handicapped at all. I know the rpm at the top of the range for that pulley, and easily estimate the rpm by how much percentage of full use of that speed I'm using on my potentiometer. If my belt is on the 1200rpm range and I'm using about 75% full throttle.....I'm doing approximately 900rpm. To my thinking, it matters not if it's not exactly 900rpm......so, why is it important to know the exact speed?
So, what am I missing here?
Note: Every single time I'm using turning tools at the higher speeds, I'm adjusting the speed for the least amount of vibration I can detect though feel, and other indicators on my headstock.......so, rpm is secondary to the vibration at that rpm. (Of course, this is not necessary for sanding speeds.)
