Hi,

I have been using sandpaper on glass for sharpening edge tools for some time. Recently I bought a couple of ceramic waterstones from TFJ. I now need a way to flatten the waterstones. Right now I don’t have budget to buy a diamond plate for this. I was wondering whether I can use the two sided (240/400) silicone carbide stones I have lying around for this? If yes, would a 6” x 2” stone be large enough to flatten a 8”x3” waterstone or must I have larger ones?

I would appreciate any thoughts on this very much.

Regards,
Dinabandhu

I just bought the bag of grit from Edge Pro. It was cheap, works good and works fast.

I have several pieces of free granite I picked up from granite places, rather than glass.

Yes, you can use stones, but the grit on the stone might work better (or not). Just bag it back when done for the next round.

I saw a tip from Woodsmith Magazine a while back to use drywall sanding screen to flatten water stones. I haven’t tried it yet but that would be a really cheap way to do it.

Edit: I would think that whatever you use should be larger than the stone you are flattening; otherwise, you risk rounding over the edges or possibly just have the end of the stone following the dished surface you are trying to eliminate.
