not sure i have ever seen that but it makes sense if you have moisture
of any kind it will expand


I like to power sand with the 2" disk in my drill. Doing so, and
varying the speed helps create a random pattern, sort of like a
random orbit sander. So moderate lathe speed, and moderate sander
speed is what I usually shoot for...

what grit do you use
sounds like it would remove a lot of material quickly

does the disk have a soft backing because i would gouge my work
with the disk edge i think if it was rigid
