Flattening a warped LP

I have the new japanese market replacement for the air tight LP flattener.
I guess you don't live in Australia, otherwise I would flatten one for a beer :--)

or you could always buy one - they are very kool

Just found an LP that sounds great(David Bowie-David Live mastered at Sterling by Robert Ludwig)but unfortunately is rippled with warps making the dynaflex nearly unplayable even with the VPI peripheral ring and center clamps. I decided I can't subject my stylus to this violent roller coaster ride and so am trying a variation on the Mikelavigne technique outlined above. I wasn't sure about the glass so I covered two pizza stones with aluminum foil(smoothly). I have preheated these to 180 degrees in the oven and will sandwich the LP until cool. Hopefully the weight of the stones and mild heat will solve the warping and the aluminum won't damage the vinyl. I have no idea how this will turn out but this was a lost cause anyway. I will post my results. Meanwhile, any comments? Will I need to reclean the LP now? Is warm aluminum toxic to vinyl somehow?

Well, I don't know about glass but the pizza stone trick definitely does not work at all. They probably store too much heat. After reaching room temp, the record was more notably warped than ever. I'm not really sure if I'll try the glass or just throw this one away. A cheap fix would be nice though. I think $1500 is too much for a disc flattener given how rarely I actually mistakenly buy a warped LP.

Can you provide the brand and model of the Japanese LP flattener? Thankks.

I tried two polished 12-inch marble tiles in the 200 degree oven and that worked great! Stick the sandwich in the oven, turn it off and come back when its cool. You're good to go.
