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....

I have heard that two panes of glass sandwhiching the record will work if used in direct sunlight during the summer months.

They said (heat depending of course) it will take 15-60 seconds.

They also said give the record ample time to cool before removing as not to bend it.

Cheers
