The Secret Society of Lathe Trolls

you had to pay a lot of money to make an effective and efficient cutting head. Things are as follows: the magnetic force [magnetic field between the N and S poles] in the gap of the magnetic system of Scan Speak speakers for $500 each is many times higher and is 3T than in Chinese vibrators for $20 ...

thanks, I was happy when I listened to your recording of the vinyl record and it confirmed my theory about mechanical recording machines, the recording is certainly real! I saw the work on Instagram by Konstantin Tokarev, he probably works on CNC machines in some company, he recently presented sever...

Your head works very high and you can hear a very large current surge to the head, the recording is real and true, I will not ask you about the transducers in the head, because it is probably the manufacturer's trade secret, but the recording is real, I think so, thanks C-Pilote

We came to the following conclusion: since two sets of Chinese vibrating loudspeakers costing $40 provide quite decent quality of recordings, but up to 7kHz, then loudspeakers from a reputable company for $1000 [twenty times more expensive] set should achieve a bandwidth of at least twice the freque...

we will go all the way, cheap cannot be good, so to be good it should be very expensive, we will check it experimentally, and in the end, if they do not burn in the head, they will remain in the loudspeakers or in the dustbin of history...

the crackling issue has been resolved

beautiful words, but that's only half of the story...https://www.youtube.com/watch?v=q_HDESJlUm0 the cause of the noise in one channel turned out to be rolled copper, it is not suitable for mastering, would anyone like to sell me a damaged copper plate for half the market price [meaning damaged in s...

We have a problem with one channel, the RIGHT one, namely there is a noticeable slight crack of the cutting knife pressing on the brass sheet, with the copper one there is no such problem, slight cracks occur only in the attack [internal] channel, is this a normal phenomenon? It does not matter whet...

I understand, but I "got a bit carried away" because I listened [about half a year ago] to high-quality analog recordings that the farmer posted as recordings cut in plastic, so I bought several sets of such Chinese vibrators, which the farmer used in his cutting head, the coils were burning, but th...

If something looks like a pig and squeals like a pig, it doesn't mean it's a real pig... I certainly won't be persuaded to buy a head made of vibrators, I told you, the farmer, that I have definitely given up on these transducers with similar speakers, said Flo Engineer [Swiss] that they are a failu...

Farmer, I'm telling you how to make it quiet and to make it so you have to do as I tell you and for that you have to pay a lot of money, which doesn't change the fact that at the moment I don't have a super strong head that would be able to cut silently with a diamond groove in copper 17kHz and I su...

Hello, this should be done from the beginning of your project, it is known that sliding guides are the quietest possible, and if you add central lubrication [like in professional precision lathes], it will be poetry and even a fairy tale... However, you will have noise and hum caused by the harmonic...

Hello , A few months ago, I asked an engineer with whom I work why it is so difficult to make a good and efficient head for vinyl records, so that it can record as well as the factory-made vinyl records. My engineer friend showed me his new Swiss watch, a very expensive ROLEX [price about $10k in th...

Hello , I don't know how you achieve a frequency range close to 9kHz using these speakers and I gave up on them a long time ago, Chinese car tweeters for $2 each turned out to be much better. I checked the small vibrators that you used in your 4OHM 20W head and the maximum bandwidth what I cut was 5...

[/img]I am considering purchasing these speakers as transducers for my head https://www.youtube.com/watch?app=desktop&v=AXWe4kAD3M0, they are highly efficient according to the manufacturer. Currently, I use commercial speakers, but the quality of the recordings is poor, i.e. low fi, no high frequen...

I understand, so it is a strictly digital recording, but there is no output. I have a Philips tape recorder and I added a second head with preamplifiers, but there is a lot of noise from the tape recorder and the tapes themselves, I will have to give up this patent. How are things and technological ...

Hello, nice equipment.
Tell me if you have any damaged copper plates for sale, I mean those for DMM which were damaged during recording or cutting due to various reasons, if you have one for sale, I will buy a damaged copper mirror.

How do you implement variable turntable slide travel and knife pressure with synchronization of the delayed audio signal? What I mean is that the support has time to position itself in the right place before the sound so that the knife does not enter the adjacent recorded groove, as is done in Germa...
