I realize this is not for a 78 rpm disc (it's a Kim Clement gospel LP 
from 1983) however the record is badly dished so that I can't play it 
well on the outer track of the first side. My question is can a vinyl 
LP be safely returned to flatness in a household kitchen oven between 
2 sheets of glass? If so then how can it be done safely? What 
temperature should I use? Where would I get the glass to put the 
record between? Or is there a better way to unwarp a record? I'm open 
to any ideas.....
 
I have never tried this, but it may work. Maybe someone out there has. Take an old cull vinyl record, super glue your warped vinyl to it, good side up. You may have to put some pressure on it with flat surfaces. Make sire the holes in the center line up. You may need a dry run at first, because super glue is fast setting up. This may give you something you can get to play to put in your computer to process later so you can listen to it. You may need to add a quarter or two to your tone arm. Let us know if this works.
