New 'Vinyl Flat' flattener?


Anyone tried one of these here yet, and your impressions/review, please?

I think I would look to do it with the optional sleeve/heat system myself.

Based upon the great input from the Steve Hoffman web site, I recently purchased a very nice Beatles Blue Box. It is a 1982 version of the Box. Maybe not the Holly Grail but really nice all analog records. The one problem I had with the box is that several records were warped. Two of the records, With the Beatles and Revolver, would not track on my VPI Scoutmaster with Soundsmith VPI/Zephyr cartridge. I started looking around on e-bay for replacements of similar vintage. The problem is that other than the warps, the records were in fantastic condition. Maybe played once or twice at the most.

A year ago or so, I read about the Viny Flat in Stereophile in a Stephen Mejias article. He is a skilled writer, and in-spite of a catastrophic failure, I figured I would give it a try. Since Stephen’s failure involved cooking the record in the oven, I skipped the oven and bought the Vinyl Flat Groovy Pouch.

I went right for it and tried fixing With the Beatles. My first attempt followed the instructions and cooked the record in the Groovy Pouch for 4 hours. I allowed the record to cool in the Vinyl Flat, without heat, for another 4 hours of so. Yes, the record was approximately 50% better but it still caused my cartridge to miss-track. I then tried 6 hours in the Groovy Pouch. Now the record tracked but still had a hump that caused an audible noise. I next let the record cook for 12 hours and cool in the Vinyl Flat for another 12 hours. What came out of this process was a nearly perfectly flat record without any trace of damage to the record. It played and looked perfect!! Next was Revolver which I just let cook right off the bat for 12 hours and allowed it to cool in the Vinyl Flat for nearly a week. On the first attempt, Revolver was fixed. I now have a nearly perfect Beatles Blue Box.

I cannot say enough about this product. I also cannot imagine a scenario where the system, using the Groovy Pouch, would damage a record. It cooks it low and slow. My advice to anyone who tries the Vinyl Flat is to be patient. Let it cook a long time and then let it cool a long time in the Vinyl Flat. Also, spend the extra $60.00 and buy the Groovy Pouch. I would not use the oven. Also note that the Beatles Blue Box records were pressed on pretty thin vinyl. I don’t have any experience using this product with heavier vinyl. My guess is that the cook times would be very long. My start time for any record, heavy or thin vinyl, would be 8 hours and move to longer times depending upon the result.

The Vinyl Flat and companion Groovy Pouch is a fantastic product at a nice price. It is very well constructed and should last a life time. If there is one concern, the Groovy Pouch seems a bit fragile but I handle it with some caution and expect it to last a life time. If you have some valuable, but warped records, give this product a shot. I think you will be happily surprised at the results.

I agree on the pouch time. Seems pretty unlikely that a record could "over cook" in this thing. I have found some records that aren't fixed by it but the ones that are more than make up for that.
In answer to the heavier vinyl question, my experience has been that the Vinyl Flat is more effective on heavier vinyl for whatever reason. The 180 gm and 200 gm discs have come out the flattest for me.
I managed to ruin an LP.In pouch for same time period as other similiar weight records,but virgin vinyl pressing.Melted the record.
Update. The latest synthetic inner rings:

I was surprised, being an original registered customer of the VinylFlat , that I wasn't sent an email from them when this new option came out. I just  recently received it.

I was having an issue after years of use with the original groovy rings that had become "not Flat" when compressed.

The new synthetic option seemed logical.

I've noticed for quite some time that several vinyl records have pronounced height in the very center portion. So much so, that when using a VPI center weight, it doesn't sit flat on these lps. This logic transfers to the VinylFlat's effectiveness as well.

My solution which is working rather well, was to trim the outer edges of the synthetic material to 11+ 3/4" diameter and using a 1&1/2" hole punch on the very center to remove that portion of the material that can interfere with the overall flattening of a lp. I also use (2) 1 &3/4" fender washers on the outer plates as a replacement for the standard washers.

So far this seems to work very well. Having the outer 11& 3/4" diameter still works well for outer edge flattening without going so far over as to overcompensate for this problem.
