I tried this same trick a few years ago, and it worked
pretty well.  Rather than clamping the glass plates,
however, I weighted the package down with large books
to more evenly distribute the pressure.  After letting
it sit on sun-heated concrete for a couple of hours,
I put the whole stack, books and all, on the kitchen
counter overnight to let the record cool slowly.  By
the way, make sure that the glass is CLEAN.  It hasn't
happened to me yet, but I suspect that one could press
dust right into the record this way.

Good listening!
