The Secret Society of Lathe Trolls

Tilt the whole machine with the turntable a few degrees to the right according to your photo [2-3 degrees of angle or more] this should eliminate the play in the turntable bearing. If this does not help, there is no noticeable improvement in the gap between the grooves, then check if the drive betwe...

Such a small sapphire embossing on a CDr [quite well and the voice is well understandable]/ Low recording level around -20dB, you can hear noise and the vacuum pump. I only turn off the vacuum pump from the 9th minute, you can't hear the air flowing in the recording. All in all, for amateur recordin...

My PC monitor broke so I took out the plastic frame and cut it to a round size [quickly] it's smooth on one side, I don't know what material it is, plastic etc..., the blade cuts nicely. I recorded it with sapphire... something like thathttps://www.youtube.com/watch?v=97Wv8hYyDxg

I didn't know where all this noise in my recordings came from, this signal comes from the power amplifier that I feed into the cutting heads, now I've connected the speakers. A lot of noise is introduced by the camera and microphones.https://www.youtube.com/watch?v=puSiewB1UIU

SAL74B [SALOMON] input amplifier for a German system with low output level feedback heads. Personally, I think that the FB [red hrame ]amplifier developed by the Swiss company FS has better parameters than the original SAL 74B. We copied both and the Swiss FB amplifier made on the AMERICAN SMM2019BN...

https://www.youtube.com/watch?v=-9vGIbm9SlQ Here is an example of a recording with a head made of computer speakers, it is difficult to determine the power of the speakers 1 to 2 Watts 8 Ohms, recording by pressing a groove with a stylus in the CD on a very primitive and light amateur device ... You...

Conclusion. In the brass head we used the design solution of the cutting head Danish DSS and JVC clone included in the patent, it is wrong by design and it is not worth bothering with it. Heads constructed in this way do not work properly. We copied this Danish solution and we believe that it is bad...

I stopped worrying about knives with artificial diamonds, because CBN is easier to grind with diamond discs and practically lasts on copper for the same amount of time, but diamond is 100 times more expensive, so for experiments I buy such used CBN knives [they turn hardened steel] for $ 10 for 10 p...

I made this recording to check the possibility of recording a 3-inch copper record in antiphase on the axis at 19 rpm and whether the voice would be understandable. As you can hear, the groove tracking is very good [30 microns], vertical modulation is stereo [no difference heard at all]. It is possi...

If made in the USA, they will maintain high quality standards and I am sure of that. I have several great measuring devices made in the good times of the USA such as Tektronix, HP, they are 20 years old and more and are in super reliable condition and have never let me down. So I will order from you...

Long live France!
Do you make knives for dmm? I would gladly buy a few. I solved the problem. This is a recording with vertical modulation. The topic is over. Thanks.

DMM copper 3 inch 72mm disc resonance problem. I don't know what could be causing this mechanical resonance, any tips are welcome.

Recently, it has become a fashionable trend to raise money for so-called "startups", once it was a proverbial "pig in a poke", what I am getting at is that first you should do a survey, marketing of interest in diamond knives, then consider whether to do anything at all or close this job and run awa...

the recording sounds like it's from another world or not of this earth or it's as old as the Holy Bible, TURN YOUR HEADPHONES DOWN A BIT because there's some crackling, nothing funny, I don't know what caused it, the head works fine, I burned a few, maybe 15 fuses, the transducers didn't burn out [f...

A long time ago I made such a head for DMM with feedback with a Dual gramophone transducer, but unfortunately such a feedback solution brings more harm and distortion than correct operation of the head. I added a coin of the Queen of England to compare dimensions. This head achieved a maximum bandwi...

The diamond guy https://www.instagram.com/reel/C-deBbZuO-6/ claims that he can make up to 80 knives in a day, it is unlikely that it is possible. At my factory, a knife grinder with a diamond insert grinds one piece of a knife with an insert for about 1 hour, but the radius is larger because it is a...

I just picked up the sheet metal, I still have to polish it to a mirror finish, so I'll make a video of the head tomorrow, and it's already 20:37 here

Misjah, today I will make an online recording on yt, you will assess whether it is worth paying $200 for it by paying to the account of the owner of this site. You know, I do not need money, I have a well-paid job. If you like the quality of the recorded signal on the copper sheet, tell me and give ...
