NANIWA Sink Bridge - Instructions
This sharpening stone holder is designed to lay over a sink, allowing you to keep your stones and your workplace clean with running water. Forget about the slimy gritty mess normally left around your water stones! The holder has soft rubber pads under the ends to help prevent scratches on the sink edges. The stainless steel stone holder is very strong and stable.
The holder can be used on sinks between 400 - 546 mm deep, from front to back.
It takes stones between 203 - 257 mm long.
Note on sink sizes: If your sink is smaller than 400 mm, the sliding stainless steel bar can be cut short by up to 70 mm (hacksaw or angle grinder). But the absolute minimum width is 330 mm!
Note on stone sizes: This sink bridge was conceived for professional use. So the best thing is to use larger stones, of at least 203 mm in length. With smaller stones you will need to make some kind of jig or frame to hold them firmly in place.
