I would like to have a two wheel buffer set up for general hobbyist polishing of handles, blades, among others. I well recognize the inherent danger of a spinning rag wheel buffer catching and throwing objects And so I ask: 1) Is there such a thing as a slow speed buffer? Do they need to be fast to be effective? 2) Any recommendations for a 6" version or will any generic HF type grinder set up work OK? Will not use as a grinder. Have a slow speed 8" with CBN wheels for my woodworking edge tools. I also have a FOREDOM hand piece with an assortment of tools but the polishing wheels are typically too small for this intended work. 3) Any recommendations for best brand of buffing wheels ? 4) Is there a better way to polish? Should I stay away from buffing wheels? Thank you very much for any suggestions/comments.
