I'm looking for some 150mm diameter polishing wheels to fit a bench grinder either to fit the 1/2 inch shaft or via an additional tapered arbour. I'm looking a the cotton type (or perhaps other materials) that can take various sticks of grinding paste to provide the final polish/shine to metal. Looking at the various options on Amazon most have very negative reviews about the quality with them disintegrating into showers of cotton fibre on first use.
Has anyone had experience with this type of polishing wheel/disk and could recommend something of better quality than Amazon/Ebay seem to be selling.
