Anyone know of a suitable replacement? I have the original felt ball that goes onto the end of the rod, held on by a bolt. This thing is nasty, old, hard, dented on one side, turning funky colors, etc. Course I could just buy a new rod/beater, but kinda like to keep using the original rod. So, I suppose what I'm looking for is just a replacement felt beater, to put onto my original rod. That possible?
