In Reply to: RE: Vinyl Flat - thin and light records posted by Akolegov88 on June 03, 2022 at 09:31:59
I successfully flatten all weights of records in my VF in both the old and the new pouch. The second variant I got was about 2 years ago with a 3 position switch.
The essential step is to calibrate the temperature - you need to get the vinyl up to 54°C. Work out the time based on the temperature/time relationship.

When I reach 54C, I switch off the power and let it cool down for several hours (I've been told that the cooling time must exceed the heating time), then check the results. Then repeat, if necessary.

That is the temperature you want between the felt.
On my original pouch, it took about 2 hours to get there and was stable. I leave it for about 2 hours for 180g vinyl and then I worked out it took about 2 hours to cool down to close to ambient.
The best thing is to program a timer to automatically switch off the pouch after your target time (which in my case is about 4 hours), then come back to it in say 3 hours to check.
The top platten is heavier than the bottom, so for best results - particularly with potato chip warps, I flip the record over and do a second cycle.
As I rely a lot on mail order, I get some pretty badly warped/dished discs due to the hot conditions en route and the VF totally fixes those discs. I treat flattening a disc as part of the cleaning process these days.

that New Zealand's range of latitudes would not be a problem. Of course, a long trip in a non air conditioned vehicle or a long time in a parked vehicle in sunny weather could damage an LP even in my Alaska location.
I think it is a problem no matter where one is - during Summer, the courier vans get very hot and I have received parcels straight from the van into my hands that were very warm to the touch - sure enough the discs would be warped. It doesn't help that oftentimes the sender has stacked CDs on one side of a record in a mailer that is not thick enough.... ideally they would have been distributed more evenly (sigh).
Even if it is Winter on my side, the "heat" problem exists on the other side or in transit somewhere particularly in the last 2 years where mail from Europe takes the scenic route before eventually turning up months later!
People often complain about warped records as though they are pressing plant defects. However, I'm finding that the shrink wrap is overly tight on many records - the cover remains bowed even after the disc is removed and of course that is exactly how the discs come out - even with box sets.
For me, I don't stress about warped discs anymore. What I care more about (other than the music) is that the disc is centred properly and there are no seam splits, or other cover damage.
Why in this day and age do with computer controlled vision systems do we have to put up with off-centred discs!!!

Thanks, I will follow your recommendation.
