The 1200 will be good enough for synthetic stones?I have a 1200 that I use to keep my jnat and coti flat. They were flat from before so it’s more like maintenance. 1200 will be pretty slow for really out of true stones, 600 will be better but might leave deep scratches.
I use a atoma 400 with good results. I just use a suitable nagura stone to smooth out the surface afterwards. The depth of the scratches also depends on the amount of pressure used during lapping. A coarser plate might not leave deeper scratches, but can be more efficient if needed.Would this be sufficient enough to lap a coti, Escher, and Jnat? I’m debating on whether to get a 600 or 1200.
