Thread: Slurry stone

Rub the bottom of your hard tomo back and forth on your wet 325 diamond plate, and then repeat at 90 degrees from the original scratch marks. It should slurry with very little effort. Repeat the process when the tomo wears smooth and is hard to slurry.

When making Jnat, tomo slurry, make sure the stone is well wet, the Nagura as well. Try soaking the nagura, for different periods of time to see if it will slurry easier.

Round one face of the nagura with a diamond plate, the face not the corner, so the portion that is in contact with the stone is rounded to minimize contact and sticking.

As you, slurry your stone, take the opportunity to work the face, especially the corners, that don’t see as much use, and to smooth the face. Work, polish any spots that feel rough, with light pressure and do more rubbing, don’t use heavy pressure, it can scratch the stone or chip the nagura.

You don’t need much slurry for tomo slurry, it should be your finish slurry, after diamond slurry or a slurry progression.

While Atoma’s probably do make finer slurry than another plate of the same grit, I doubt it matters much, as the diamond slurry will break down anyway.

So, try your DMT with light pressure, it may take a bit more working, (minutes not hours), but circles and or half laps will speed slurry breakdown, depending on the stone and the tomo nagura.

Experiment, it is all part of the art of slurry, and it can be art. It is, what you make it, they are, natural stones…
