    Default Record flattening

    Pulled out 96's "Mercury Falling " and to my surprise is warped , not massively but enough to make me worried if played .
    I looked up possible options and Analogue Seduction offers record flattening service , anyone got any experience with ?

    Large pot of warm water. Place on top of record with pillow case between record and pot and leave to cool. Repeat increasing heat until satisfied with result.

    Alternative is to press record between two sheets of glass and load heavy weights on top, ideally books. This can take a long time to work, even weeks.

    It only takes a little heat to flatten a record, two sheets of glass and a hair dryer will work well, use as little heat as possible, and stop the instant it flattens out. Trying to flatten a cold record will most likely cause cracks.

    The guy in the video in the next post warns of burning the record and flattening the grooves, youíd really be using way to much heat if that happens. A little common sense goes a long way here.

    That is why the warm water in pot works so well. There is a reservoir of heat energy that dissipates slowly, and the pillow case allows for a slow build up of warmth rather than full on heat.

    I tried that and it worked like a charm. I left it at least a week, might have been longer. A seriously warped record, warped from new, became completely flat and playable. Until a few months later when I went to play it again and it had reverted back to its original shape.

    Yes I can see the logic in the warm water method. One important step is to remove all heat the instant it returns to flat. You could put something flat on top at that time, that is not hot, to be sure it remains flat as it cools. But even that may not be necessary?

    Iíve got one album right now that has developed a warp. My Jethro Tull, Auqulung. Iím not sure how that happened? Itís stored with the rest of my records, which are not warped. I suspect it has always been there, but over the years Iíve noticed that sometimes it seems very warped, and other times itís only slightly warped. Why? Perhaps the jacket is screwy, and is applying force on the record depending on humidity? Or perhaps when itís warm the record expands and makes it worse?

    Sometimes itís just slight and the needle will track it fine, and other times the needle will get airborne as it passes over it for about two or three rotations before it settles in and tracks. Iíve made a habit of dropping the needle about 10 grooves from the beginning to spare the needle the wear and tear. It would be a good candidate to experiment on, and see if I can flatten it with warm water. The three Iíve made flat before have stayed flat as far as I know. But I used two sheets of glass and a hair dryer on those. I didnít heat the glass, I heated the record, and laid the glass on top once it was warm enough to flatten out. That was years ago, like 25 years ago maybe? And I had seen an article about two sheets of glass with the record in between, placed in the oven at its lowest setting. That sounded risky to me, so I thought of the hair dryer method. But apparently others have had success with the oven method? As always, thereís more than one way to skin a cat.
