Maybe I'm just a dumb wood abuser, but I use a piece of glass, about
11 x 14 inches, and I sprinkle some 90 grit carbide sand stuff on it
with water. The glass sits on the workbench top, so is mostly flat,
and it works great. The glass came from a cheap picture frame, the
sand from Rockler I think, not expensive. Anyway, just a minute or so
on each stone gives me a flat surface. Hope this helps.....
