Hi Mike
"You did not specify that it was a particular situation with exact needs
(for example the 10mm that they request)."

In my first post I wrote;
"They say to, take a "chip" 27x 46 mm rectangular and 10mm thick epoxy it
to the glass then cut off the chip as close to the glass as possible leaving
just a thin slice attached to the glass.

And the web link was posted at the bottom. I think it was just a
miscommunication, no harm done and thanks for your reply! : )




Thanks, Tom
