Gilbert Posted March 16, 2008 Share Posted March 16, 2008 Bought a 1994 sealed LP that ended up being warpped. While resting on the platter, the warped area raises approximately 3/8". Bugs the crap out of me. Is there a fix, or should I just trash it and get another? It's not an super expensive Lp, it's Nirvana's Unplugged MTV gig. Yea, yea .... it seems to play fine, but still bugs me. Quote Link to comment Share on other sites More sharing options...
mas Posted March 16, 2008 Share Posted March 16, 2008 If possible, I would just get another. While I suspect you will get many suggestions, I know of no method that will 'relax' the higher mass body of the record that will not also relax the MUCH lower mass of the encoded grooves as well. You may very well 're-warp' the record body, but what is the value of the encode information to you? I defy anyone to warp the body of the record without also modifying the grooves as well. Depending upon the nature of the warp - a record clamp may help to mitigate it... Quote Link to comment Share on other sites More sharing options...
jheis Posted March 17, 2008 Share Posted March 17, 2008 Gilbert: I don't know if this will work, but it's worth a try. I've been pondering this off and on for a while 'cause I've got an old Spencer Davis Group LP that was one of my favorites until someone used it to level a slide projector - with predictable results. Anyway, I was thinking - stick the album back in it's sleeve and place the whole thing between two sheets of quarter inch thick glass and leave it in the sun for a couple of hours then let it cool before removing the glass. The combination of heat and the weight of the glass might do the trick - 'course I never got around to trying it. Don't know if I even can find the album any more....

oldbuckster Posted March 17, 2008 Share Posted March 17, 2008 Give it up, discard it ............. That is why I dumped vinyl, the 80's was full of warped records, off center holes, and when you returned them, and got another copy, it was the same or worse ....... chalk it up as a loss ....... there is nothing you can do ...... or, maybe put a quarter on your head shell !!!

mas Posted March 17, 2008 Share Posted March 17, 2008 the 80's was full of warped records, off center holes, and when you returned them, and got another copy, it was the same or worse .... Buc, I couldn't agree more! Seriously! And I would add small dimples and little rectangular chunks of vinyl filler much like grog in clay to that list! I had friends in Cats Records and we would open up to a dozen copies of a title and inspect them - it wasn't an isolated pressing - it was the entire run.

colterphoto1 Posted March 17, 2008 Share Posted March 17, 2008 There is a technique involving a barely warmed (think pre-heated and OFF) oven and two sheets of 1/4 TEMPERED glass. I don't know to what degree the grooves would be warped. I used this a couple of times back in the 70's but can't recall the results. I think the LP was playable but can't comment on the quality- I wasn't as picky back then. Quote Link to comment Share on other sites More sharing options...
billybob Posted March 17, 2008 Share Posted March 17, 2008 ***EXPERIMENT: If over 18 you may try the glass sandwich approach, but in a microwave oven instead. If the waves are not yielding temperatures suitable after a couple of minutes on this non organic material(s) spray Pam on the issue to act as a catalyst for heat induction. This is my more modern approach over the old oven, which yielded less than desirable results. Back then clamps was too profound for my processes! Clamps = Genius, IMHO !

JJkizak Posted March 17, 2008 Share Posted March 17, 2008 Cut off a piece of a Chevy crankshaft and tape it to the tone arm. (this is supposed to be funny) Cut holes in the turntable and hook up several vacuum pumps with a 12" pipe and seal-bearing to the turntable with a 5 hp motor hooked to it and when the record hits the platter you will hear this stupendous clunk sound as the record goes perfectly flat. (this is also supposed to be funny). Vinyl is very particular about being cooled properly to prevent warping. This problem is strictly a production process whereby the guy with the cigar says "crank it up". Gee, I thought those expensive turntables and cartridges were supposed to track that crap.

billybob Posted March 17, 2008 Share Posted March 17, 2008 LOL 1 Guy with the cigar says "Hit it again", "I need a bigger hammer! That gave me another idea, you actually are restamping it! "Where is that damn steamroller?" Quote Link to comment Share on other sites More sharing options...
garymd Posted March 17, 2008 Share Posted March 17, 2008 Gilbert, Just don't look at the table when you play the record. Everyone has a couple warped LPs. It's all part of the fun. If it sounds fine, what are you worried about? Quote Link to comment Share on other sites More sharing options...
Gilbert Posted April 1, 2008 Author Share Posted April 1, 2008 I forgot about this post, and remembered when I played the record earlier this morning.... The sound truly is superb, and when I look the other way it doesn't bother me at all (magic). But the record wasn't too expensive, so I'll get another. If the replacement LP sounds as good or better, then I'll experiment with my slightly warped LP. mas, I'm gonna find a way man, I'm gonna do it and defy the odds.

kaiser SET say Posted April 1, 2008 Share Posted April 1, 2008 Or take the WARPED AUDIOPHILE route and either buy an HRX setup with ring flattener and center weight or just buy one of those new fangled disc flattening machines and you can fix mine also[][] Quote Link to comment Share on other sites More sharing options...
oldbuckster Posted April 2, 2008 Share Posted April 2, 2008 Cure for Warped Record : ............ 1 12 gauge Shotgun, and holla' "PULL" .......... that's about all you can do with them, or make ash-trays !!!!! Quote Link to comment Share on other sites More sharing options...
maxg Posted April 2, 2008 Share Posted April 2, 2008 Its been about 3 years since I listened to a record without using the outer-ring from clearaudio on my own system. Flattens anything I have. Alternatively there is a review of a furtech device to actually permanently flatten a record: http://www.soundstage.com/vinyl/vinyl200709.htm Quote Link to comment Share on other sites More sharing options...
NOSValves Posted April 2, 2008 Share Posted April 2, 2008 Gilbert, Warped records are for warped minds...........in this case a perfect fit [] Quote Link to comment Share on other sites More sharing options...
