How best to eliminate LP warps

Yes, you are right that there is "different" types of warps and severity of them.

The point is to get a better understanding of the material and how it works/act and flattening is not always the end goal and the assumption that we are done and all is going to be back to how it were only if we get it flat.. when there is other things happening and getting worse as a by-product. That we don't concider and take into account that is good that we know of and take it into account. (Oh, this record is to much warped or have a type of warp that makes that individual record "unrepairable" so it can be played again.)

Yeh the server warped disc experience I described before were a great educational thing for me that made me think about what really happened and how it works. When you have bigger warps then it is easier to see the actual effects of the flattening process. When the effects also will be greater.

I went into the project with the mindset that only I straighten it up to flat then all will be good and restored back to its original shape/state as a goal. And did not concidered any other factors that were a mistake from my side that I learned from.

And I probably think that many others also focus on to get it flat and think that it will be 100% restored back to its former shape. (But for smaller warps no one will notice any change or degradation even if they are there.)

@lewm , the solution is simple. Get a turntable with vacuum clamping :-)))))

And, a record flattener. 

@lewm , if i understand your situation, you have a very  small percentage of your LP collection with warps that concern you, BUT , when played, you dont notice a mistracking or audible problem....may i ask why you why wish to attempt to remedy this?  If its not broken, dont fix it.. I have a few similar, as well, BUT also dont note mistracking or pitch problems....it has bothered me, but I just shrug my shoulders....

but they’re only for sale in Japan, and only at 100V

@drbond  They've been available in the UK for ages...

Dear jw, Your assumptions are not quite accurate. I normally do not fuss over warped LPs, as I observe them very infrequently in LPs in my collection of 2500 or more LPs, but I would not dare to guess what fraction of that total is warped. However, in the last 2-3 weeks, I observed on separate occasions that two of the LPs I selected for play on those particular days (to be clearer, one LP per listening session) were warped "severely". Especially affecting the outermost one or two tracks on each. Since I only noticed the warps when the LPs were already spinning, I was also able to observe that both LPs sounded great, were tracked well by two different high compliance cartridges (B&O MMC20CL and Ortofon MC2000 mounted in Dynavector DV505 and Triplanar, respectively), had very quiet surfaces, no ticks or pops, and great music. Because of the latter good qualities, I am loathe to discard the LPs. Normally if an LP is as warped as these two, I discard them; they usually have some other defect that justifies trashing. So I started wondering what are the latest and most cost effective methods for flattening; I would not spend the $3000 cost of the Furutech, which I already knew about, because the problem is so unusual in my personal experience. I would not make the general statement that I don’t have a problem playing warped LPs, only that these two LPs play OK.
