In the videos I've just watched, showing different VR machines making cuts, it appears that they are all like the configuration you drew on the left side of your image. Also dann, just do it that way - and try to cut with the stylus, upright... In these videos, his vinyl cutting head looks up a litt...

{Danke, Tim E. Ich dachte ich wäre in Oberammergau.} sat159p1, you might need to adjust the mounting of the stylus holder (collet) so that when your cutting head is looking down, the stylus is upright. In one of the pictures I saw that you uploaded to the Vinyl Mastering forum, it looks as if the cu...

Warum nicht in Lack schneiden, das ist weich und klingt gut? Beim Schneiden in Vinylchloridrohlinge (anstelle von Apollo-Lacken) sollten VCA und SRA die von Souri bezeichneten sein. Dies liegt daran, dass sich die geometrische VCA in PVC von derjenigen unterscheidet, die benötigt wird, um eine effek...

Normally, the cutting stylus rake angle will be only 2 - 5 degrees from perpendicular to the lacquer (jawohl, ever-so slightly plowing, rather than stroking) when the effective vertical cutting angle (VCA) is 20 degrees. {Nygaard says to cut with the stylus perpendicular to the workpiece without nam...

Here's a picture of an Ortofon cutting head mounted in a Neumann lift/drop. The adaptor block on the back of the cutter provides the desired angle of the dangle once it's attached to the saddle: http://www.audioinvest.no/images/suprdisc/omr_cut.gif Here's the Corinth (also posted, elsewhere, on this...

Do you measure its protrusion in mm (w/ an inspection mic) and compensate each time the diamond stylus is recut so that it sticks out just as much as specified by Souri? According to Nygaard, the way a conventional corundum disk-cutting stylus (with burnishing facets of 3 µ for stereo and 1,5 µ, for...

I saw an interesting thread here: http://forums.stevehoffman.tv/threads/some-commentary-on-vinyl-quality.123380/ The OP pasted a commentary by Classic Records which had specific problems with lacquer brand and silvering. "...Transcos became noisy as a result of their supplier of nitrocellulose aceta...

Uniform Civil Code automatically indemnifies the vendor of a "good" from errors of the customer in specifying customization of the good to be sold to him containing infringing work (i.e., you're hearing: "I want you to cut tightly spaced grooves, but make sure the modulation is to this master tape p...

If you have an SP console with the cassette bay for svelte processor chassis that are possibly known as cassettes, you might be interested in this offer. There are two of the PTMV "CALIBRATE" cassettes, and one of the KS 70 "NUMBER OF TITLES" cassette in need of TLC, but possibly fixable... Also usa...

I strongly recommend you stay analog with your music signals - 100%.

Monogroove mono vinyl is hard enough to get right, so there's still a noble challenge awaiting enthusiasts, and this is where I feel we should focus our Helium-less futures.

Fear God; not the Church!

Peace and grace be with you, Todd.

Hey, we have to wait on some cuts until the Neumann console ash tray is repaired. (Smoking client with some impatient guitar licks). Even if all you can sell is just one of the Bakelite handles that are squeezed together to make the upper bottom of the ash tray open onto its lower cache-ash zone, I'...

Maybe the "Secondary Depth" you have is for "Increased Depth during banding, lead in, and Finish?" This was customary in the past. It is easier to drop the needle manually where the groove width is greater. Of course, by increasing the depth, we are also increasing the width (by twice the depth incr...

Hey, above? it's ok, but you have to read that stated "half-inch"-Lead In groove length (for 12" pressings) as being both in "disc diameter" inches (which is half inches for every stated inch, making it 1/4" in reality, I mean, radius))... It's the head trip to the lead in cancel spread. ): - Father...

Get yerself a microscope and behold what you are (not) leaving behind. Even if you're strictly impressing, it's a microgroove cutter, after all. Even coarse grooves of 10 mil width and 110 included angle needed microscopy. A monoscope with reticle of known spacings is adequate, and a tv camera proje...

..as for the length of the Lead In groove, it depends on the disc diameter of the target pressing. The target pressing's disc diameter also affects the blank's disc diameter of the Cancel Finish trip which makes the lockout spiral (inner circle) at the end of side so as to park the pickup after the ...

Bill, what Tim E. is saying about the Neumann response is true for the -68 when used with the -66 and earlier. However, the SX-74 when used with the SAL-74B is able to deliver up to 20 kHz +/- 1 dB, according to Larry's book. Also, if the -68 is used with something called the CA-72, which Neumann wa...

This book is now in limited supply and can only be ordered on eBay, afaik. There might be around 20 copies left, and no more are planned to be printed.

Nice stuff on every topic, from styli to CD-4.

Well, I did a test. I played drums with brushes and my dog walked in the drum room and sat down to listen. When I switched to sticks, even played gently, he immediately left the room. As Bram Stoker's Dracula said, there's much to be learned from beasts. It was clearly the SPLs which informed my own...
