I’m not sure what’s possible. Determining when you reach the full apex and raise a burr is probably not feasible. IMO, nothing beats the finger swipe. I was thinking that the “noise plot” would level out when say a 400 grit has removed all the 200 grit scratches. You could then minimize the strokes and metal removal. I downloaded some sound analysis software, named Audacity, and the forum talks to the non-triviality of the measurement of sound. Yet I figure the “scratch noise” is predominant to other residual noise and may be ripe for some interesting experimentation.
I will be looking at this more in the short term after I finish retrofitting my 1×30 Harbor Freight with a variable speed treadmill motor.
Also, for some reason I am not getting email notifications on replies (box is checked).
