Some old-time fixes: 1)Wrap a heavy screen-door spring around the drum. Overwrap it with friction tape if necessary to keep it in place. 2)Cut several 1" wide rings radially from an old inner tube. Stretch the bands over the drum. 3)Add a heat-and-shrink steel drum band. You might also try hack sawing 1/16" deep slots 1" apart, at a 45 angle across the shoe linings. If all else fails, get a 1000 watt sound system.

Add to that,....4) encircling drum with Jubilee clips ( do you call them that- worm drive hose clips anyway) use two or more joined together so the drum doesn't get out of balance.
