I had heard somewhere that it isn't wise to use to coarse a grit to lap stones as they can actually affect the grit of the hone being lapped (that sounded confusing after I wrote it). I have a Shapton 16K stone and was wondering what would be appropriate to use to lap it with.
The DMT 8 C will work fine for your Shapton. It is 325 grit and does a fine job on most stones. The grit of the lapping plate doesn't affect the grit of the stone being lapped. That is set when the stone is manufactured (or formed, if it's a natural). The lapping plate can affect the surface texture of the stone being lapped and some users will go to either a finer plate or sandpaper if they are concerned about it. I don't, and haven't really noticed any negative effects from using a 325 grit lapping plate, whether it is a DMT or a Shapton DGLP.
Thanks very much
You can use the DMT method or the sandpaper method. I used 400, then 600 grit sandpaper on a big chunk of granite that was cut out for a sink...before I had it, i simply used the countertop and care to not scuff the stone to the countertop. Didn't take much for my stone to get the grid cleaned up and gone, hope yours is the same.
8BallAce,
The highest 'grit' stone I have is the Naniwa 12k, and the finish my DMT325 leaves on it is excellent - the razors don't complain anyways :)
Have fun !
Best regards

You may be thinking of Spyderco stones, which are said to be damaged by lapping, in a way that changes their effective grit. I have no idea why this would be the case, but have read it in a couple of posts by reliable sources.
I know you have to be careful using wet/dry sandpaper. With some of the cheap sandpaper grit from the paper can come loose and embed into the stone.
I've never seen grit embedded in a stone as a result of lapping, but I've seen scratches in a stone as a result of lapping. I would advise using the highest grit flattener you can, whether it's diamonds, sandpaper, or whatever. It might take a little longer, but the results will be worth it.
I love the DMT 325 grit plate, use it on everything and lap everything with it, don't worry about issues.
It's great for chipped razors too.
I just got a Chinese 12K that I used my Norton Flating stone on then I used my 4k on it then my 8K. I am pretty impressed at how well it came out. I also noticed that the 4k and the 8k appear to be cutting better.
This was after I just tried to use the flating stone on the C12k. The shave was good but not where I wanted it to be. I had read an old barber book that the author stated that he used all his stones on each other. I thought what the hell. ( Im not known for being the sharpest tack) I have to admit that after I was finished, all my stones were smoother and when I sharpened the 5 razors that I had waiting I was really suprised with the results. I guess I say if you got them and a little time then rub'em together. These were all waterstones that I was rubbing against each other.
OK, after all this talk of rubbing stuff I think Im going to go see my girlfriend. Later Guys.:hmmm:
I am surprised the norton lapping stone made a dent in the CH12k. That fuggar is hard
You are soooo right when lapping softer stones. Only "wet & dry" sandpaper, typically black can be used. 400 grit wet/dry is a staple that I use around the house, so it's normally my starting point on lapping. It just seems to be faster for me than my DMT8c.Quote:
