Flattening a warped LP


Do any of the Goners know of an audio club or audio dealer that owns one of the LP "dewarping" machines and will flatten an LP at a reasonable cost? Thanks in advance. Ed

it's been a long time since i used this method. i think a standard residential window pane using tempered glass would be about right. too heavy and you could have the glass make an imprint on the grooves at the high spots. you are better off doing it twice than getting glass that is too thick.

a 12" x 12" window pane has sufficient weight to work.

as far as shattering the glass......make sure the glass is not cold to begin with......run it over increasingly warm water and then thoroughly dry it.
1/8" plate glass will be fine, not tempered, unnecessary. Don't worry about temp, you are only bringing it to approx. 200 degrees.
one other note; you want a gradual increase in heat for both the Lp and the glass....so don't pre-heat the glass very much....just make sure it's not real cold.
I have had success using a hair dryer as a heat source instead of the oven.
