Woodworking Tip: How to Flatten and Maintain Waterstones

[@Donorcyclist]

I'm curious about grit of the sandpaper as well. Thank you for sharing this.

[@WoodsmithShowandmagazine]

I would say 150 grit is good.

[@9HomeWorlds]

awesome thanks for sharing, wet dry is the way to go its so cheap and easy

[@garychristiansen508]

What grit of silicon carbide sandpaper did you use in this video? Will aluminum oxide or alum. carbide sandpaper work?

[@palmcottageguy]

I like the simplicity of this method. What grit of paper do you recommend?

[@WoodsmithShowandmagazine]

I would say 150 grit would be ideal.

Curious about two things 1) is the any recommend types of sandpaper or will any wet/dry work. 2) what kind of diamond plate is that?

[@christopherbound2154]

Looks like an Atoma diamond plate.

What grit of sand paper?

[@vikramkrishnan6414]

Why not just use the sandpaper on a flat surface to sharpen the chisel itself?

[@KellyVisionPictures]

If you rub two water stones, of different grits together, don't they contaminate each other and dilute the water stones original grit?

[@WoodsmithShowandmagazine]

It is possible to get a little surface contamination but once you rinse the stones off and make the first couple passes with your blade that will disappear. That can be completely avoided by just using clean sheets of sandpaper for each stone though.

[@Leold124]

Why not just flatten the second stone on the sandpaper. Why put more wear on the first stone flattened - you are rubbing the first, newly flattened stone on a non-flat surface. Doesn't make sense to me.

[@chrisbock72]

felt the same way. maybe if you did not have a sand paper set up. I like to use the back side of 12x12 or larger ceramic floor tiles for flatting my oil stones they are flat and very hard and do a great quick job.

[@WoodsmithShowandmagazine]

Yeah, we just kind of through that in as another option. I would really recommend using a separate clean sheet of sandpaper for each grit so you don't contaminate the stones with the other grits.

Typically you need three stones to ensure a flat surface, two stones can make a curved surface that both stones share...
