I purchased a set of Norton waterstones a while back and am very satisfied with them. I'm having problems with keeping them flat though. Their flattening stone is great at dressing the stones but is useless if it is not flat. I tried to flatten it with 60 grit glued to a granite surface plate. The sandpaper doesn't last worth a darn though. Does this scenario sound familar?
I'm considering a DMT extra large coarse diamond stone, hoping it will stand up toe the extremely tough material that the flattening stone is made of. Any suggestions?
thanks in advance
