I don't mean the kind that you make on a lathe and magically the rings appear. I mean the kind where there's a plug, with some beans or lentils or bb's inside and they rattle around. It looks like there's some tool that can drill in and pull out a plug, and then you fill that space with rattly things and then put in part of the plug so there's still space left for it to rattle around? I can show a photo if you want to see what I mean!
