   Glenn, Don't worry about tiles comming off because you groove around
them. You need these
channels to relieve suction and to roll abrasives around and return them to
the face of the tiles.
  Some may disagree but A solid or almost solid surface to surface causes
too much suction and
no where for the water to move other than into suction bubbles or to the
outside of the pressure
surface. This is why I do not like glass tools. The other reason is why
grind glass two times, once is
enough. The idea of taking a 2x4 and a hammer to unstick two pieces of
expensive glass sounds
like a nightmare to me., but this is the discribed remidy after soaking in
hot water, or freezing, or
praying they will separate. Tile tools are great, don't worry about
channels, just keep your tool clean between grits and scrub real good. All
will be O.K.  I think Bob May said grind more, worry less, and
as long as you keep all clean you will be alright. (If Bob didn't say it he
should have..)
