I managed to create a significant amount of dishing in a granite sink cutout in the process of flattening both sides of my Spyderco 8x2 fine stone. This was about two hours of hard grinding, though! For those who don't know, many diamond plates have been ruined attempting the same process. I suspect that would be equivalent to many months (or even years) of flattening stones that dish from use.
you spend 2h to flatan the spyderco fine stone? it seam a lot for me did you put loose silicon carbide on the plate you use? i never spend more then 5mn for any stone
@@dris9274 For comparison here, I never spend more than 30 seconds flattening any of my waterstones. That's where the Spyderco stones are different from nearly all other stones -- You only flatten them once when new and then you never need to flatten them ever again for the life of the stone.
@@dris9274 I used 45-70 grit SiC when I flattened mine. If I had it to do over I would have gone 32 grit SiC. Also, the medium/brown stone isn't nearly so bad, I think I got that one flat in about 10-15 minutes per side.
@@rockets4kids wow, incredible. maibe is the fact that it's on granit? maibe it's fone grind better on glass? or maibe it's tge sic that is not hard enough
I am using a piece o glass too to flatten my stones but I have spoken with somebody and he uses a piece o tail granit instead of glass. He is telling me that the granit does dish at all. I am planning to test that too.
When lapping smaller stones on coarser grit I work at the corners of the glass but never thought of flattening the hole surface. It's 5$ every 2 years. But I have mat finished with 60 grit SiC a big glass 80x65 cm for an interior door for a friend ones

I have an old video with a granit tile and it dishes to.
@@stefanwolf88 Than I need to buy myself a spare piece of glass. :)
Could you flatten the glass?
