Professional vinyl record lathe step by step

[zdenek]

I was provided with a brass housing for the DMM head, I didn't know it was so big...

We received information from the magnet manufacturer that the magnetic force of magnets decreases with age by about one percent per year, which means that old heads that are several decades old have lost their effectiveness and electromanetic efficiency, so there is no point in purchasing a head for thousands of dollars because it does not meet the manufacturer's requirements. And so, regardless of the type of magnets used in the head, one percent per year loss of the magnetic force of the magnets after ten years means a 10 percent weaker head, after thirty years 30 percent and after half a century the efficiency is no more than 50 percent of those old recording heads etc. So the old heads are very worn out, like everything that is old, I think so too.
What do you think, trolls?

Edison recorded his voice first, why record other people's voices? So record your voice and upload it to YouTube. Then no one will accuse you of copying someone else's voice, and this is not in accordance with the law of ownership without the owner's consent, right?

We received the original galvanized stainless steel plate with great difficulty, it is a complete shock for us when it comes to the hardness of the copper layer.
The situation is as follows: these COPPER MIRROR plates for DMM are VERY SOFT, it may be slightly harder than wax or hard paraffin or PVC plastic, etc. .Even by gently moving your fingernail, you can irreversibly scratch such copper, not to mention the use of a diamond knife... .
The copper layer is very thin, like the thickness of a hair on a stainless steel plate. However, rolled copper is at least ten times harder than galvanized steel, so these are two different worlds but it seems to be the same copper... it's a different copper.
This galvanic copper, after cutting the disc, can be listened to three to five times and it deteriorates, degrades the high frequency band, then the small cuts of the high frequency above 17 kHz become blurred and each subsequent listening to the disc deteriorates the acoustic bandwidth, so it is a myth about listening to this copper disc multiple times. ,pressed vinyl record is much more durable.

Hello, these very fine teeth are a recording of a frequency of 40 kHz with a level of 0 dB in copper, groove width 0.025 mm

[zdenek]

The recording is original, made with my machine and my DMM head

[zdenek]

I'm considering buying such a multi-colored lamp for my lathe, I think it will go very nicely with the black granite base of my machine, what do you think, trolls?

[zdenek]

We are still testing the system, nothing is free, precision has to cost time, time is a very expensive element of this puzzle...

[zdenek]

Hello, together with electronics we have developed a module for measuring the temperature of drive coils with a constant resistance of 4.7 Ohm and 8 Ohm.
and current intensity directly when the online amplifiers are turned on, i.e. in real time while cutting the board on a lathe. You will need four amplifiers with a minimum power of 250W, a total power of 1kW. The amplifiers can also be of lower power, but then the recording signal may not be very precise.
If anyone is interested, please write on my website, the first person will receive the module for free to test [possible shipping costs],
The module is great, it has four indicators, two for measuring the temperature of the L and R channel coils and two for measuring the L and R current.

S", how to eliminate these consonants because they are a disturbance?

and here is a great recording and it is easy to distinguish vinyl from digital processing and S" is not distorted

[zdenek]

the cause of the whistling sound was a slightly dull diamond knife, the problem was solved, the quality of the copper recordings is fantastic

[zdenek]

I have to add something to this thread.
It seemed that one sharp diamond could record at least several copper records, but it turned out that this was not the case.
With one sharp diamond knife you can record only one hour in copper, and probably forty-five minutes and that's all, but trying to record the second hour is a risk of noise and distortion and a significant deterioration of the recording quality. After one cut, the diamond knife needs to be sharpened to factory condition. , that's all. The price of DMM recordings cannot be low... by the way, if anyone is interested in this method of recording...

ATTENTION! A warning or warning, hence the question: DIAMOND or ZIRCONIA?
That is the question... And there is also a known answer.
We wondered why a knife with a diamond blade wears off galvanic copper so quickly.
We bought several "diamond" knives from different manufacturers and here's a big surprise. All the knives that we bought as diamond blades turned out to be ZIRCONIA blades, why?
Have we fallen victim to fraudsters? We do not know ...
Small loss only $2000....
You can't make any claims against the sellers because the product is sold as jewelry and unfortunately you can't get a refund anywhere in the world. It's hard, that's what we said and moved on.
I went to a jeweler to check whether the knives we bought had diamond blades. The jeweler and diamond cutter quickly assessed and concluded that it was not a diamond but a semi-precious ZIRCONIA stone. That's all there is to it...
Currently, we have purchased equipment for grinding REAL DIAMONDS and unpolished diamonds and we make REAL KNIVES WITH REAL DIAMOND BLADES that last on galvanic copper for a very long time.
Good luck, turners! Be careful what you buy and from whom.

Excuse me, but you remind me of a local madman...

You cut directly into copper and brass, buy speakers for $500, and not a single real photo of your machine or mechanics, much less the cutting head. Now you are thinking about real diamond and zirconium... Progress really does not stand still, everyone has long known about synthetic diamonds, which in this topic are much superior to natural ones (due to the absence of impurities, constant hardness, etc.) in terms of characteristics.

Anyway, keep entertaining us. You definitely amuse me .

The main thing is that you do not sell anything!
This could end badly for buyers!

P.S.: And this is already a WARNING!

Hello ,
I saw your recorder, there is no way you could cut a groove in copper on your machine.
I don't know why you are so aggressive.
I have time, I'm in no rush to publish anything and I have no intention of selling anything to anyone.
I don't make the machine myself, only professionals make it for me. My machine has already been modified many times, mainly in terms of its stiffness.
If you read my entries carefully, you will understand their meaning.
$500 for one high-class loudspeaker is not much of a price compared to the project I undertook together with people who know metal processing.
Would you like to see my machine?
Of course you will see it and hear real recordings in galvanic copper, so wait a little longer.
You have been on this website since 2012 and have not published many recordings, and I have been here for a year, so don't worry, you will see it soon.

Clear pneumatic cylinder. The photo even shows factory stickers covered with a piece of paper with the inscription “zdenek”.

If you just wrote, it wouldn't be bad. It's worse when you start selling...

Did I say that I bought zircons from you instead of diamonds and that you blame me?
I said in general that knives called diamond are not, that's all, and I won't buy them again.
I don't need what I'm selling anymore and it costs $1,800 plus shipping.

One more thing on this topic.
If you suspect that your diamond is not a real diamond, it is very easy to check it with ordinary corundum sandpaper.
If it is a real natural or synthetic diamond, the diamond will scratch the surface of the corundum sandpaper and there will be no scratches on the diamond, absolutely no corundum will scratch the diamond.
You can only scratch a diamond with a diamond.
