Dear Galoots,
What would be the best bit of kit for flattening bench stones; I have amassed a 
good stock of bench stones now from car boot sales and flee markets, lots of dif
ferent types, they are almost all badly dished with chips here and there, I have
 tried sand paper dry on float glass and end up with little dips, I think this i
s because I am not flushing the waste away and it clogs parts of the sand paper,
 maybe water would help? - I am currently using Japanese waterstones  (which I k
eep perfectly flat) for lapping my chisels and plane irons but waterstones are s
uch a pane cause they wear so quick and are so messy. I love some of my old benc
h stones and want to get them propperly flat. I want a tidy solution - aggressiv
e cut as there is a lot of material to move and was thinking of buying a diamond
 stone??? , any advice would be much appreciated.
Mark
