Best commercial press for flattening warped LP's

The very best? It's said to be the Air Tight Record Flatter. Made in Japan, and has to be ordered from there at a very cool $1,700.00. Nevertheless it is said to work, and it is the only such device I know of which has that reputation. I know one person who has one, and he says it works.

Tobias,

Thanks for the quick response and help. Sorry not to have caught this sooner. I am looking into possibly getting one of these machines. If I do get it, I will post a short review.

Why not look at a used dry mount press for flatting prints. It would be considerably less expensive. I haven't tried it myself but it's worth looking into.

A dry press won't work - the vinyl has far too much 'memory' and will go back to orignal shape as soon as the record is removed from press. I tried !
I also tried with two panes of glass sandwiching the LP and running under very hot water from tap - not hot enough.
I have not yet tried the oven yet with the glass sandwich as suggested in an LP forum but this will need experimentation not to de-form the vinyl too much....
