 We've all seen a record warped by storage. It is the result of prolonged storage while bent slightly, but usually without any heat. So, I wonder: could one flatten a mildly warped record just with weight and time? If so, how long would it take to make a difference? Has anyone tried it?

 Just buy a VinylFlat and Groovy Pouch - much more reliable. Warped records are almost a given either in production or distribution. Even the Tone Poets I bought recently needed flattening.

 The Orb DF-01iA High-end Audio Vinyl LP Record Flattener is the one to have. A little over $1000. Easy- just press two buttons, come back in four hours. I've flattened many with it. All survived with flying colors. A great machine!

 I've not used an Orb but it seems very expensive for what it does and isn't unconditionally safe to use based on the other thread. Apart from the automation aspect, what other advantage does it have over the VinylFlat in a Groovy pouch? The VF combination is a fraction of the Orb's price and takes about the same time! I also think that it has greater flexibility in the choice of rings vs full coverage mats to adapt to 7"s and LPs with a raised label area and thin playing area. Combinations of the rings/mats enables almost all types of warp (including potato chip style) to be fixed even on very thin 7"s that often have a very thick and non-uniform label area making it challenging to flatten in a simple "sandwich maker" type of device unless the Orb has special inserts as well.

Either way, I consider a device to flatten a record absolutely essential irrespective of budget. IMO, the VF is cheap enough to be considered an essential buy for most enthusiasts and does the job automatically with the addition of a mains timer - I use a smart timer which is controlled via an app on my phone to adjust the time required per cycle according to record mass and size.

 not too hot sun for an extended time. The old post said this method did succeed. I just did an archive search using "warp + sun," and there were lots of posts about placing an LP between glass in the sun for an extended period.

I tried it for a very long time in a garage and between two plates of glass. I even added some type of weight, but the warp never went away. It was over a year before I examined the record.

 I too have often read of using sunlight and two pains of window glass, but I certainly would only do this very carefully.

In a paper by the cartridge designer Van den hul , he suggested using butcher paper between the glass and the record, and I think this make sense, permitting some ease of movement between the glass heat source and the vinyl. Of course, his remarks were made at a time before butcher paper became plastic coated on one side to prevent liquid intrusion, so I would probably just grab some plain paper inner sleeve material for the boundary layer.

 

Ah, clever idea. Nt, posted on November 23, 2022 at 22:05:36

 Yes. Someone posted here before about flattening out a warp by just storing the record in a tight place for a long time. Don't know if it was horizontal or vertical. Was it Beach Cruiser who posted that? Don't want to speak for you, Beach Cruiser.

 I had a record that I bought used that had a ski jump warp on the first song of the record, it would literally fling the cartridge out of contact with the record surface.

It had a nice song about food on the album, so I kept it, and played it occasionally , omitting the first cut. ( album from a band called,"pure food and drug act" if memory serves)

my desire to own records conflicted with available storage space and sanity, so they are really jammed in there, in a vertical storage.

After an indeterminate amount of time, I was surprised that the record had returned to its original , as pressed , form- no warp. I live in a moderate climate so nothing above room temperature was involved.

Things are so tight, my latest stratigy is to remove the storage cover from every other album, because that much plastic takes up room that might hold another record, while still preventing ring wear.

It not like I have a valuable curated with skill collection, just like to keep things nice.
