Don, and the rest of the porch:

Seeing as diamond hones are expensive, I too would be reluctant to use them for
flattening whetstones.

My father used to “prospect” for whetstones among the glacial till of upstate
NY.  He’d flatten “candidates” by rubbing them on a smooth concrete surface,
with plenty of water and some rubbings from a common red brick.

Not sure what the brick was supposed to do, but it made a nice slurry. 

(I do not recall that any of the “found” stones was a great whetstone, but at
least one of them would crudely sharpen a pocket knife.)

Maybe coarsely flatten your stone on smooth concrete with water and then use the
expensive diamond stones to put the finishing touches on it?
