About "Vinyl Blanks"

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.

Can someone tell me what the story is with "vinyl blanks"??? As I understand it these are vinyl pressings that can be cut even on a professional lathe.

Does anybody use them and what do they sound like?

Hi,

I already try to cut blank pressed vinyls. Result is not so good.
the biggest problem is the noise. the pressed vinyl is very hard to be cut with a stylus (diamond or nhs) PVC blank records are better.
the other problem is the life time of the record, shorter than PVC too.
One time, a cut was good (I mean no noise) and the sound is really better, bass frequency are really better. I have been cutting those records with a vinylrecorder. Maybe someone else here already tryed to cut with a professionnal cutter....

hello,

As I understand vinyl record is not the same PVC, and it is better to be pressed. Somewhere I read about vinyl record material and PVC is polyvinylchloride.

There is some more questions on my mind:
is the material just black PVC? Does anyone do PVC blanks for yourself or buying from somewhere? ;)
The thing is that when buying PVC it goes in sheets. Question is how to do it perfectly round?

Thanks

This is not just black PVC, there are so much sort of PVC...
On this PVC, there is a small mirror surface (very hard to find, only in germany I think).

but its called PVC, or it has some kind of other description?

I went to local shop where those kinds of material are. There is some kind of PVC that I think would be good. Unfortunately they are out of stock, so i'm waiting when new package arrive and i'll try cut on them.

posted this elsewhere-

Four years ago I heard a blank that had been cut on a Scully. The impression, the cutter gave me when we talked, was the trade off was stylus wear not sound quality. Something like 75 cuts on lacquer compared to 7 on vinyl. The blank supplier was different, I vaguely recall the name 'Bamboo Guy'.

Aussie0zborn hey,

Between you me, the compound has to be the softest of the softest to be used for cutting, and then some. The dies would have to have no profile, so the cutterhead could track.

The system I had heard it on was not professional, so cannot speak for sound quality.

The guy handled the thing like it was glass, yet other records like tissue paper.
