I watched gssixgun's video on prepping the JaNorton 4,8 stones and found the progression of finer flattening plates of interest. I have an Atoma 140 that I have used to flatten my synthetic waterstones. Having been stricken with the dreaded HAD, I am the proud father of a JNat and a few other finishers.
Is the Atoma 140 too coarse to flatten the Nakayama Asagi? If I lap it with the Atoma, should I polish with a 10K?
Yes, the 140 will leave very deep scratches in your stone. Where did you buy that stone? It can happen that you don't need to lap it, or if yes, than not much. If the only stone you have is the atoma, than use sandpaper on the backside. I would use 400-1000-2000, that should do the trick, and your stone will stay flat for a long time. A 10k stone won't lap out the scratches a 140 Atoma will leave in your nakayama, and you will waste more stone than you need to.Quote:

I was sure someone would tell me I had to get a 400 grit Atoma, and feed my addiction!
Actually, I have a 400 Atoma, and it work wonders on my synth waterstones, and my naturals too. I like to polish my Jnats more, because everyone says it is better that way.
I am happy to help feed HAD, mine is pretty serious too :rofl2:
