Anyone from Mexico City here? We will be meeting up this Sunday somewhere in the Condesa. Post here and DM if you want details!

Damn! That would be really cool for me. But it's too far away from Austria. Things rarely go off here. Have fun. Thomas

Hello, this should be done from the beginning of your project.. I wasn't clever enough to do everything right from the start … 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... Manufa...

Drive unit FP-9 09/2023 After installing the rails (and parts of the structure), I was curious to see how the new bushings (plain bearings made of iglidur® material) have changed in terms of noise compared to the recirculating ball bearings. . . Bild 53a.jpg . . I found an old video where I recorde...

Drive unit FP-9 09/2023 I decoupled the stepper motor using rubber bearings to minimize the transmission of vibrations. The toothed belt and the bearings also support this aim. . . Bild 52a.jpg . . Good adjustment of the position of the motor and tensioning of the drive belt in the installed state ...

Hello ,
A few months ago, I asked an engineer ...

I take note of your opinion and that of your friend.

THX

Thank You for more than 1.000.000 views. I am delighted that so many people are interested in the development work.

Greetings from Austria

Thank you for the questions and doubts are always justified. I would like to respond briefly. Hello , I don't know how you achieve a frequency range close to 9kHz using these speakers ... Thanks to matching spiders and extreme weight savings. I checked the small vibrators that you used in your 4OHM ...

That looks realy nice, Thomas,
Well done.

Thank You

New complete lathe FP-9 (CNC) 09/2023 In order to be able to install the new drive in the lathe, I have redesigned the entire device and am now assembling the CNC parts. First, the central base frame is produced. I use aluminum profiles for this: . . 20230920_175913.jpg . . Then the new base plate ...

Hello Krisgge, I am not a professional and have no experience with VR. But I do have a little signaling experience. The sound piece is certainly not easy to cut cleanly because it doesn't allow any mistakes. With a signal (almost) exclusively in the 1.5 - 2.7 kHz frequency range, you can immediately...

New FP-9 cutting head (CNC) 09/2023 Before I start assembling the new parts of the complete lathe, I have prepared a look at the CNC milling of the new cutting head. Why am I building a new cutting head again? The reason is not because I can. It's because I have to. An inner voice tells me that the...

That's a great and creative idea! I like it.

Improved feed drive 09/2023 To ensure that the drive is not only quieter due to the bushings and the spindle, the drive for the feed of my turntable should also be improved. Changing the pitch of the spindle makes it necessary to adapt the entire drive motor structure. Improvement 5: Stepper motor ...

Improved spindle drive 09/2023 As already mentioned, I would like to improve the spindle drive in three respects. Firstly, it should be quieter. Secondly, it should be even more precise. Thirdly, it should be maintenance-free. Improvement 2: Spindle For this reason, I have replaced the ball screw w...

THX > 250.000 Thank you for over 250,000 views. I am pleased that there is a lot of interest in the field of record cutting and also in the process behind it. You are still welcome to post your ideas, criticisms (or even confirmations). Inspiration is the basis of every development. Thank you from ...

Assembling driver coils with spider and cone 09/2023 The new press dies for manufacturing my metal spiders are finally ready. So I can start pressing the aluminum spiders from the new material. The "old" presses were intended for thinner sheet metal and there were always cracks during production wi...

Hello evildrome, two brains - one thought! Regarding ball screws, I considered "upgrading" the half scale VMS 70 to ball screws but abandoned it as an idea due to concerns over noise. The VMS 70 saddle actually does run on ball bearings (which I did not know when I made the half scale model). If I h...

Looks great,

I am really curious how the cone from one piece affects the sound and the resonances.

Lu.

Hello from Prague.

Me too
