Vinylrecorder and blank disks

This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.

Vinylrecorder and blank disks

Hi,

Spent last few days cutting records. Hadn't turned on my Vinylrecorder since Spring... So, as usual, lack of practice and quite a few damaged records to start with. Then, everything starts to run smooth again!

I'm actually running out of blank discs, got around 25 left right now. The last 25 I cut were perfect, but all of a sudden I'm having problems with these last ones. They are all slightly bent on one side, about 1 mm. So I can't cut them because cutting stylus will "jump" after a few spins and I'll ruin the recording.
I've stored these records vertically since I bought them from Souri two and a half years ago and they are the last from a 300 Lp's order, regular weight, not the 180 gr ones.

So here go my questions:

- Is it better to store them horizontally? (makes no sense to me)
- Is it possible to "de- bend" them? (maybe heat + weight)
- Is this an usual problem with Souri's blanks?
- Maybe not so usual with 180 gr discs?

I have a few of souris blanks that are slightly warped as well.
From what I can tell mine were stored horizontally.
Wish I had a better answer for you!

Have you talked to Souri about the defective blanks? He's usually pretty quick and happy to replace for you. I had a handful with the center holes not being the right size, also a small batch with some "humps" in them.. I reached out and he quickly replied and said "this is problem with manufacturer, will replace on next order."- or some such Souri-ism.

Same goes for appollo lacquers as well. Always happy to replace defective blanks and lacquers!

Cheers!

Ok, I asked Souri about this issue. This was his criptic answer:

- Is it better to store them horizontally? (makes no sense to me)

No

- Is it possible to "de- bend" them? (maybe heat + weight)

No

- Is this a usual problem with thin blanks?

No

- Maybe not so usual with 180 gr discs?

No

And that's it, dealing with Souri is always fun!

I have repaired regular warped albums with 2 pieces of glass with the album in a paper sleeve set in the sun.check it by lifting the top piece of glass bout every 10-15 minutes.when the album doesn't raise up put it in the shade until it cools,done!
