King Arthur’s Tools supply a powered sanding and polishing system called Guinevere. The same range of inflatable rubber bulbs and mandrels used for holding the sandpapers is used to hold the polishing accessories. The rubber drum or bulb that holds the polishing cloth is inflated with a simple pump, similar to a bicycle pump. A unique valve is located inside the rubber so that no sharp edges protrude to potentially damage your workpiece. A range of brush sleeves for buffing, cloth sleeves for polishing and KAT’s own non-toxic organic waxes are available. All can run up to 3000 rpm and all come in kitsets or are sold separately.
