How best to eliminate LP warps
I own about 2500 LPs, and I like to think they're flat. Furthermore, I espoused the view that warped LPs ought to be discarded. But lately I have found 2 or 3 of my LPs that do have warps but sound too good and are too precious for the music recorded on them to throw away. So I am in the market for ideas on how to remove warps. I am aware that there was a device on the market that looked like a large waffle maker, to be used for warp removal. I think Furutech made it, but I never see it advertised these days. I am also aware of the DIY method of placing an LP between two glass plates and heating the ensemble. The question there would be how hot and for how long? Any suggestions are welcome, especially opinions on the efficacy of the Furutech. Thanks. Please no comments on vacuum hold down; I think it's a great idea but none of my five turntables has that feature.

I'd say unless the record is unplayable live with minor warps. I've tried traditional and modern methods of trying to flatten reocrds with varying degrees of success. Last machine used was the AFI Flat. Most of the time it works pretty well, but it has ruined several records including a numbered Blade Runner soundtrack on red vinyl and a sonically mint early pressing of Fleetwood Mac Rumours. The Blade Runner was a strange one as I had successfully flattened many colored records but QRP must have used some non-standard vinyl formulation that made it susceptible to heat damage. After treatment a rough orange peel pattern appeared on the record and it was unplayable. Other owners of this record have also experienced ruin using a variety of de-warping methods. Caveat emptor when using these devices. |
The Vinyl Flat and Groovy Pouch has worked great for me. I got one for my birthday in March of this year. Every warped record that I've tried to flatten came out nearly 100% flat. I first preheat the Vinyl Flat in the Pouch to 130-140F. Then I put the LP in the Pouch at medium temperature and monitor the temperature to keep it 130-140F. After 2 hours, I unplug the Pouch and let the Vinyl Flat cool while still in the Pouch for another 2 hours. Every record, both brand new and used ones from the 70s and 80s have come out flat. |
smatsui,Thanks for the heads up. Seems to be a great opportunity for someone with enough 'bent discs' to spring for one. The last album that I got had a sort of double warp, i.e., one right after the other! |
