Now cut a strip of sandpaper, and wrap it around the drum much like the scotch tape.
Since the scotch tape is sticky side out, it will adhere and hold the sandpaper strip.
Cut the excess sandpaper strip away, make sure there is no overlap. If you cut it abit short, that's fine.
Overlap on the other hand has nothing to adhere too, and you don't want loose bits rotating at 5,000+ rpm.
Now slide the roll up above the rim of the drum so that it protudes 2-3mm (1/8").
