The Secret Society of Lathe Trolls

the 7 inch small hole lacquer coated aluminum blank has gone the way of all things, I'm afraid...

I use a Neumann VMS suspension box, they never specified what grade to use, but 3 in One oil works perfectly and it doesn't
weep all over the place!

Fascinating if somewhat eccentric study!

Please see the Apollo / Transco discussion thread...thanks

I don't know much I'm afraid...saw one being cut at RCA NY around 1980...the cutter head was an Ortofon ,red in color...half speed I was told...that's all I remember haha!

It's on Wiki 'RIAA equalization' you'll be sorry you asked

I don't understand the continuing love affair with DMM....

I seem to remember it might be SAE 80 gear oil

Hi George... number 31 went to Optimal...could use it now!

OR..on Neumann's they use a dash pot, a depth solenoid and a hold back spring to accomplish the same thing.

have never seen info on neumann feed screws...if you're a machinist, it should be fairly simple to measure the pitch and angle...maybe!

Thanks Barry and Steve....have started a VMS 80 Owners Club in the reference section. We'll see how many are interested in disclosing the whereabouts of these machines!

Here at Finyl Tweek London, we have numbers 36 and 48. If enough users contribute, can we get badges like on cars,

The VMS 80 direct drive pitch system might be worth looking at regarding any new designs people might be contemplating....

best not tell them then...

Since Sennheiser abandoned any interest in the lathe side of Neumann's business, does it mean that it's effectively now in the public domain?

Most of the people who worked in the disk cutting side are no longer around. Are we free to 'reverse engineer' the designs if we so desire?

Thoughts?

So, Sennheiser abandon the Neumann lathe line..now Shure gives up on cart making.

Two manufacturers of lacquers, one of cutting styli, a handful of people who can rebuild heads and know their way around disk cutting machines with vinyl on the up turn.

Wotta woild!

AND you need a special 'record' player to enjoy the full 'benefits' of this tech!

Re inventing the wheel again...

Let's re do the pre emphasis curve! I'm sure back then no one ever envisaged today's overly bright digital recordings.
I mean an 18 db boost above 1K. a bit much maybe!

Totally wishful thinking! I mean modifying all those pre amps just kidding guys!

Once everyone has stopped laughing, let me know if anyone out there has one of these for sale.

Got stuck with an older version of this pitch card which was never swapped out by Neumann

I live in hope, don't we all....
