Thread: Chinese 12K as a Dressing Stone

I have several myself, and I sell the C12k slurries. A small piece of the larger C12k stone. As far as using it as a "Dressing Stone" I'm not sure. They are far from being flat when purchased and need to be lapped, which can be a job depending on the condition of the 12k. When you say "Shapstone" You mean, "Shapton" correct. The only thing I would use on a Shapton is the DGLP. Maybe a D8xx followed by wet/dry sandpaper. Would the Chinese 12k have much effect on a Shapton, I doubt it, but I could be wrong. It would probably raise a slurry, but why would you want to raise a 12k slurry natural on a 16k ceramic? Experimentation is fine, but you normally want to keep your slurries the same as the host stone. Some guys don't believe in slurries at all and feel it you need to go lower in grit, use a lower grit stone. I also think you may be confused about the Chinese 12k. They are used with a slurry, not as a slurry. The are very slow finishers. 100 laps is the norm, or it can be reduced by raising a slurry to 50 laps. Even though the Chinese 12k is a lower grit than the Shapton 16k, it's still very smooth and will not lapp or dress a shapton if that is your intent. Lapping a Chinese 12k can be a job in itself, Even with the right tools, with a D8XX, DMT of choice for stone lapping, or D8C, just be sure to use plenty of water while lapping it can take some time, I've heard some members say ti took them hours to lapp theirs. I know Maximillian uses Shaptons and so does Chris L, Check with them, I would think some wet/dry sandpaper and a tile, or the DGLP, expensive, but worth it if your a shapton user. ... I just woke up, and apologize if I've taken your thread out of context.
