I've given my WS 3000 a workout over the past couple of days and replaced a worn 400g abrasive on the glass wheel this morning. The adhesive didn't want to let go. I couldn't peel it off. I tried denatured alcohol and acetone. Acetone worked best, but I fought this thing for about 15-20 minutes. How do you guys remove these things? BTW, I do have short finger nails, don't bite them, but do trim them close.
