We have a ton of records and luckily none of them are damaged. We are aware that plenty of people do have warped vinyl records that they wish they could repare and still enjoy. Wired posted a wiki inspired instruction manual on how to repair warped records using two sheets of glass. We were a little skeptical at first, and wish (well not really) that we could try this out at home too. It seems pretty easy and if all goes well, you should be able to listen to that record again!
Here's how Wired suggests repairing your warped vinyl:
1:Go to a thrift store and find a few warped records to practice on. Also look for two pieces of glass to make an LP sandwich with. The glass should be about 14 inches square, or thereabouts, and ¼ to ½ inch thick. Old picture frames or shelves are a good bet.
2:Put the record on your turntable, and try to get a good idea of how serious the warp is – use a ruler to estimate the displacement at its worst point. You'll use this for reference after you bake the LP and spin it again.
3:Press the LP between your two sheets of glass, and put the platter in your oven at 200 degrees for 5-10 minutes.
4:Let the album cool and check it again on your record player to see if it has improved the warp. If it has, you can repeat Step 2 to see if it will flatten out even more. If it looks the same as before, you can also try upping the heat by 10 degrees at a time.
They also offer up solar heating options and even more alternative options if you're not keen on the baking options.
