Re: Long term struggle with suction noise, what am I doing wrong?

I have the audio recorded somewhere, but I have recorded it some time ago so I'll have to find it. I'll try.. The noise is comming from the nozzle as you can see in the video, when I disconnect the nozzle from the silicon tube that goes to the chip jar it is suddenly pretty quiet. The vacuum platter...

Long term struggle with suction noise, what am I doing wrong?

Hi, I have been struggling with this for a long time and still haven’t figured it out. I am able to get decent sounding stereo cuts with my setup, but the noise of the chip suction is very audible in the silent passages and in parst with lower volume. I am using powerful side channel blower with VFD...

Re: DIY vacuum plate

Hi,

the pocket in the middle was too big and the suction was too strong, so the blank warped down, I had to put supports and reduce the suction, it took some fiddling, but now it works pretty good. The depth is just 1mm. I use old ELMO Rietschle side channel blower.

Re: The farmer and his plow - When I set out to build a record cutter

Cutting music again at last I still had to fix a few signal problems, which I will write about in the next reports. After I had finally fixed the interference, I was able to make a music cut again. An old friend from school visited me in Austria again. He now lives near San Francisco (California) a...

Re: DIY vacuum plate

Thank you for all the nice replies, I will take some more photos of the spindle and of the piece with the o ring. I am glad if someone found this useful. Amazing work! Really great to see more innovation, using an existing platter is a great idea :) More photo's of the spindle and 0-ring would be go...

DIY vacuum plate

Hi, I thought that this could help or inspire someone, I got inspired from this spinnertownblanks blog post https://spinnertownblanks.com/blogs/spinner-town-blog/diy-sp10-vacuum-platter and tried to make my own vacuum patter, bacause I was tired of warped blanks due to heating. I used old and heavy ...

Re: Silent groove noise, anyone familiar with this sound?

Yes, that's true, it is a bit bigger, originally i had there 5mm diameter alu pipe, now there is 10mm brass pipe, The smaller one had problems picking up the swarf, the bigger one works just fine except the noise. A friend of mine has the end of the pipe pointed down to the record - I am posting a p...

Re: Silent groove noise, anyone familiar with this sound?

I use Elmo-Rietchle side channel blower. It is in the same room and I don't have any enclosure for it yet, so it is pretty loud in the room. I am waiting for a silencer to arrive, but I don't think that the lathe picks up the noise from the room so much, the blower is pretty far from it on the other...

Re: Silent groove noise, anyone familiar with this sound?

Yep. but I am affraid that 0.5 mm wont make a big difference... Here is recording of the silent groove while the speed of the suction motor is slowly turned down and in the end the motor is completely off.

Re: Silent groove noise, anyone familiar with this sound?

So after months of silence, I did the platter mottor assembly again, now i have no platter noise in the groovea and I would say acceptable wow and flutter. But the main PITA was the ssshhhh whistling like noise in the groove. I have tried everything, setting different back angles, lowering the downf...

Re: Silent groove noise, anyone familiar with this sound?

What? I think I don't understand, yes the cut has been done with the head in the photo in the first post and it is just two Visaton BF32 speakers, so no feedback coils. It is actually inspired by KNOP's design which I have found on this forum years ago. If you mean the clicks in the sound It is just...

Re: Silent groove noise, anyone familiar with this sound?

Hi, Thank you for your reply! The files are recorded trough the same preamp, same pickup and the same interface, but the music file has been normalized to -14 LUFS-I, so it is probably louder than the silent groove recording, but you can hear the same noise when the song ends, so that is the level. ...

Silent groove noise, anyone familiar with this sound?

Hi, I am more like observer. I don't post much, but I have learned a lot from this forum. I am working on my diy lathe for years and at last I am getting some consistent bearable sounding resuts. The lathe: stereo dynamic diy head, heated stylus, oil dashpot, lenco heavy platter, belt driven by caps...

Re: The farmer and his plow - When I set out to build a record cutter

Looks great,

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

Re: The farmer and his plow - When I set out to build a record cutter

Your work and effort is awesome, lot of inspiration. The sound of the cut is well balanced although I can hear some distortion on esses and cymbals in the 4-6kHz range. I have the same problem that I am trying to fight with all sorts of dynamic EQing to get the cut louder, but my head is far from pr...

Re: Periodically repeated noise in unmodulated groove, broken tip?

Thank you for the tips, today i have found that the noise disappears around the center of the blank and comes back near the end again, so it is hopefully not a broken tip, but maybe some geometry problem or warped platter.. Any other ideas? The vacuum cleaner is getting really hot, so it is probably...

Periodically repeated noise in unmodulated groove, broken tip?

Hi, I have built my own lathe with cutterhead design by KNOP during the lockdown. I was trying to be as precise as I could, there is a oil dashpot so that the head goes down really slowly, the whole system is controlled by arduino with MIDI support, so everything can be operated from either DAW in a...
