Let’s see. One foot diameter times pi gives 3.14 foot circumference. Times 1725 rpm gives a linear speed at the edge of the disk of 5,416.5 feet per minute or just a hair under one mile per minute. It would appear that touching your fingertips to sandpaper traveling at 60 miles per hour is not a good idea!

Hope the fingers heal soon.
