I bought a record last week that was so warped that my turntable
would not track it.  I therefore decided to try a technique I had
read about for unwarping the record.  Here it is:

Obtain two pieces of 1/4 inch plate glass about 13 inches square.
You need glass that's heavy enough to keep the record completely flat.

Put the record between the glass sheets and put the whole sandwich
in the oven.  Turn the oven up to 150 degrees for about 10 minutes,
then turn the oven off and open the door part way.  Let the glass and
the record cool to room temperature (about an hour).

The record came out completely flat!  Score one for the good guys!
