Thread: Atoma 400 lapping Jnat

I just scored a new Atoma 400 at a great price. I only have one finishing Jnat that I use to keep my edges going.

Can I use the Atoma 400 to lap my stone?

If so, do I have to use a higher grit Atoma to finish lapping ? Like a 1200

Will it leave deep marks ?

Do I have to lap my Atoma 400?

You can't lap a diamond plate. Yes you can use the atoma to lap the jnat but most would use a higher grit to finish lapping with. 1 brought a 1200 replacement grit sheet and put it on the back of my 400 plate to make a duel grit plate.

If you have nagura stones, then just use those to smooth the top out before using

Thank you gentlemen.

So lap using the Atoma 400, then use my nagura to polish it? Just like when I'm creating slurry to hone?

I have a smaller stone that I rub on my Jnat to create slurry. It might be the same stone just a smaller piece. Not sure if that's what's meant by Nagura. It's not one of those special stones with stamps that are specifically sold for that purpose.

Thank you. That was very informative.

Yea, you got it. The 400 will get the stone flat, your Toma Nagura will make it smooth, as will just about any higher grit stone, your 1k? You can feel the stone face get smoother as you rub it. Or you can just hone on it and it will smooth out. A lot depends on how aggressive your plate is, how clean, and how much pressure you used with the plate.

You can raise a slurry with a diamond plate, then raise a thinner slurry with your Toma to finish. It should be finer, but you have to experiment.

Most new diamond plates do need to be smoothed, as the diamonds can be irregular and may have some high diamonds that can scratch. Rubbing some steel, a chisel, sharpen an axe, Kitchen knife or lapping a couple stone will usually smooth it out and it is good from there.

If down the road, your diamond plate feels like it is not cutting as aggressively, scrub it with some cleanser and a stiff brush, let the cleanser sit on it for a few minutes, I like Bar Keepers Friend for this, makes a big difference and will keep a plate cutting for a long time. I have some plates over 10 years old that still work well. Using too much pressure or without lube, water for stones and Windex for steel, or water, will rip the diamonds from the substrate. But if you use a lubricant, clean them and go easy on the pressure, they will last a long time.

Thank you for he advice. It should arrive today. If I sharpen stuff with it (axe, etc) won't this wear the Atoma irregularly? Won't the Atoma then need to be flattened?

When you hold it in your hands then I think you will understand what is being said.
