The Secret Society of Lathe Trolls

Assuming you're cutting on lacquers: ...I don't know anything specific to the VR recorder, but these are some general things to check/be aware of: - The coating on the the Apollo/Transco discs are generally not flat all the way out to the edge. ( i.e. ripples, bumps and other defects on outer edge w...

Nice one mike!

Some of the DMM lathes were also converted back to lacquer cutting lathes. Who knows where those left over dmm parts went… To my knowledge, Dmm has a hi frequency carrier, different suspension box,head, vacuum system, amp calibration etc etc… unless there would be a purpose built dual lacquer/dmm cu...

Excellent news : ), keep up the good work!

Congrats on all your progress Todd!

It's interesting to see how the orientation of some of the yarn threads indicate a flow of vinyl towards the center of the disc.

Hello,
What's the intended use of a digital copy of a test record?

All the best to you Martin : )

DMM = direct metal mastering. i.e. cutting into a coper disc instead of lacquer. It represented the state of the art and the last hooray from Neumann in cutting lathe technology before CD's took over. As far as fidelity, the 7"33 can be the worst of the vinyl formats. (inner diameter tracking distor...

+ It might be good to at least get a lacquer ref of the long side so there are no disapointing surprises down the road.

Yea such a bummer, I really hope somebody acquires the assets or at least get's some documentation on the construction & tech specs etc. The company invested so much time & energy in R&D for the progression of vinyl playback technology. The Shure V series was a benchmark reference for many cutting h...

Would be interested to know how many of these plants do their own plating.

Thanks Steve,
This is very much appreciated : )

I believe that "Audiophile" is a recording / mixing / mastering aesthetic.. as well as song composition. If that's not present in the recording, then the average public most likely will most likely not recognize it as an audiophile record. So technically if a plant cares enough & has the persistence...

Drum roll please…...

I just had to post that, all in good fun : ) 10" you can plan on between 10-15min per side @ 33rpm. Amount of low end, stereo image and program time generally dictate what fit's and at what quality. Not all lathes operate the same way so these numbers only apply on certain systems. As for cost, It's...

Thanks for the info George : )

Back in the day there were 12" copper blanks that refs were cut on.
I don't know if any of the DMM facilities offer copper refs today..??

Glad to see the work Flo is doing, really great : )
