A compact and comprehensive system for both the use and storage of waterstones up to 12" in length. Twin clamping arms hold both coarse and fine stones at the same time with the aid of fully adjustable quick acting clamps. When not in use a cover keeps the stones clean, dust free and prevents evaporation. The large base unit has room enough for three or more stones. Manufactured from tough, rigid ABS with all metal parts in non-corrosive stainless steel and anodised aluminium. The base features non-slip pads to hold it firm when in use. The cover consists of a tempered glass plate backed with laminate which can be used in conjunction with 90 grit silicon carbide (supplied) to lap the stones to a flatness of plus or minus 0.001" per inch of stone length. When not in use, the coarse stones can be stored directly in the water and the finer, wooden based ones left attached to the bar and just flipped over to be stored upside down. The whole thing can then be covered and stored ready for the next time the stones are required.
