Just to point out... if you're drilling through the glass and it's

pages ;-)

You do NOT drill the glass, you drill holes through the gap between
the panes (through the seal).

Aha! I'm glad you clarified that. I was reading that as drilling the
glass.


But what about jj's remarks in the OP, he was advocating drilling the glass
wasn't he?

He did say glass, but I interpreted that as the glass seal.
