The Secret Society of Lathe Trolls

Hi! I did my last cut yesterday (Metal track) and I'm very happy with this result. I use a carbon fiber to hold the needle (I am experimenting glue the needle to the torque, it is not the best way...but..) and I start using only diamond tip between 95-100 degree angle. The speaker cones are made by ...

HI Trolls!

My mistake of the last file because was digitalized in MONO.
Stereo one here: Joel

Hello! I did some changes in the needle and torque. I got some tips from Nedelcu, I take off the screw in the torque to make the head more lighter. Actually, it worked. I can control better the weight when I touch the needle on the disc. I changed my needle (influenced by EposLab) with a alumminium ...

Hi Tasos, Congratulations! That's a remarkable work progress. About the position of your needle with 100º angle, how do you avoid the hiss sound and not to turn into a cut record when the needle touches the disc? I suposed you use My Shank PVC, I tried my self and they are very sensible without any ...

Hey Trolls! My last cut of today, a little bit better but my needle is dying and I got some noise of course. Emboss 3 - 28 NOV.mp3 I am using a tungsten needle on My Shank disc, the angle is 60º of the needle...and is with 'cone' format, I will try with triangle to know what I get.I heated the disc ...

Hello! Updates: Some new cuts with some EQ experiments. Second emboss My Shaknk Disc (First EQ).mp3 This one I used some corrective EQ...a little bit better than the first, Last emboss (My shank Disc) 2nd EQ.mp3 My last one has a better EQ, but I had some issues during the embossing...maybe the need...

Hello Trolls! Some progression here. I made a new cutterhead and I did some experiment with the embossing technique (or tried it). Some pictures of the new cutterhead: 20231125_202538.jpg 20231125_202441.jpg 20231126_195548.jpg 20231125_202531.jpg 20231125_202448.jpg I was impressed for the result, ...

Hey Tom,

Congratulations! That's sound great. What exciters do you use in your cutterhead?

Best regards
Joel

Hey! I'm back for the project. I am starting to build a new cutterhead...more detailed and accurate than the first one. About the exciters, what do you think about this one? Or I should stay with the tweeters? https://www.soundimports.eu/en/dayton-audio-daex30hesf-4.html?id=76847138&gad=1&gclid=CjwK...

My first attempt were tweeters with crossover, Peiying PY-T59. I saw in this forum some people and on youtube too suggesting these pair. 51jFCNX6PTL._AC_SX679_.jpg https://www.amazon.co.uk/PY-T59-Peiying-Speakers-tweeter-neodymium/dp/B00XJIL7PM Do you think they are enough to continue testing? Best ...

Hello Constantin! Congratulations for your project, it's really well designed. I am working on my first handmade lathe project too and I have been embossing only with CD's and I had problems with the output volume and surface noises. Do you have any advice? Your cutting sound for me is up than I wis...

Hello Thomas! I 'rebuilt' the cutterhead with the steps you mention before, I embossed some CD's and the 1khz sine wave for testing the output, but the sound recorded has not changed at all. I think I need to create a new improved cutterhead... Have you any advice of tweeters and other precise mater...

Hello Thomas! I think I know what you mean, and yes, this construction has no spring and probably make some changes when is recording. When I built it, I tried to figuring out in my mind how to control the level manually and experiment different weights. Then when the needle is on the disc with the ...

Hello Thomas! That sketch you made is very clear about that mecanism you have been explaining. Meanwhile, I found a very lucid video of what you mean, I supose you saw already. Take a look: https://www.youtube.com/watch?v=s62GfJEr6PI At the end of the video, he explains exactly what you mean. Is a t...

Hello Thomas! Thank you for your great advices and knowledge, it will help a lot. I agree with you, my cutterhead definetily needed some improvement but I didin't know how to do technicaly. About the topics: 1. Yes, I will try adjust more the angle of the needle to know the difference on this first ...

Hello Throlls! I am a newbie on this wonderful forum and started cutting/embossing a couple of weeks ago after build my 'machine'. After killing 30 CD's, I finaly got a sound! Pushed it to the limit on pre-amp and power amp, but got a low, low volume and some distortions. I am writing here to share ...
