I use Shapton waterstones to sharpen my blades and I flatten them with a diamond plate. For coarse work I have a grinder and other diamond plates. I don't have running water in the shop and flattening the stones is a pain because they have to be flattened under running water. I have been thinking about other options when I saw this on ebay. Minus the hand nozzle it would make a good sharpening station with running water.

Would recirculating water be a problem? Obviously I'd change it regularly and keep a few drops of bleach in it to keep it from getting stagnate.
What do ya'll think?

Thanks,
