When my 3m polishing wheel was worn down to about 4" diameter, I figured I could make use of the wheel rather than discarding it.
I took a 1.5" hole saw and made 5 smaller polishing wheels. Admittedly the hole saw took a beating, but I now have 5 polishing wheels that I can spin onto the threaded arbor for my die grinder.
