The Guinevere Inflatable Sanders are pumped up through an air inlet in the drive shaft located in the bottom of each sander. The air valve design leaves the bottom flat without a clumsy protruding valve on the sanders. This patented solution makes it possible to make superior cylindrical drum sanders as well as a unique rounded sander with a Round shape at the business end.

This molded rubber bulb constantly flexes and changes shape, making the sander soft all the way to the edge, appling the sander’s total width against the work piece or only the edge in all kinds of complex sanding. The sander actually becomes flat when pressed against a flat surface and round when pressed against a round surface i.e. the sanders conform to the underlying surface. Consequently the sanders should be filled with very little air.
