Dowel-rod "key" pulls sandpaper tight on drums
If you have trouble getting the sandpaper tight on your sleeveless sanding drums, try this trick. Find a dowel that matches the diameter of the hole that you tuck the sandpaper into. Cut this dowel 2" longer than the length of the drum, then cut a kerf down the middle with a bandsaw. Stop the cut 2" short of the dowel end.
Now, trim and install the paper on the drum. Insert the dowel by sliding the kerf over the ends of the sandpaper and twist the top of the dowel to tighten the paper. Remove the dowel and insert the regular key.
