The Secret Society of Lathe Trolls

Hey , I used a grampian style needle because I had one lying around. Could make a neumann style hole as well in the torque tube, but I'm not sure if the stylus would clear the cutterhead body. The counterweight are the metal plates on the backside of the hinge. I seem to have issues with one channel...

Got the swarf suction kind of working. The swarf is sucked away consistently, but my poor vacuum cleaner overheats every two minutes or so. WP_20161227_17_04_30_Pro.jpg Good enough to some test cuts now, but am looking into a vacuum pump. https://polyestershoppen.nl/vacuummaterialen/olieloze-vacuump...

Diamond + Blanks from Myshank. I would like to cut a lacquer someday but not really comfortable with the flammable swarf thing.

Ok this is a really interesting project. I had no clue to the workings of such a head, but now it seems pretty clear reading this thread. Really cool stuff.

Ok so I rebuilt the head, made a swarf tube but did not test it as of yet. Did a weighting of all the moving mass, it sums up to 5,5 grams. Here is the head response using IRIAA and white noise, now just 3 resonance peaks (the 100hz also appeared in a silent groove, so I guess some 50hz mains harmon...

I did some test cuts of audio, but especially the vocals sound distorted. Then i recorded a white noise + inverse RIAA back into the pc, but forgot that my dj mixer was set on sum to mono. got this result: grafiek 2.png But then the (biggest) issue became clear: the two drivers have a very different...

About the mechanical decoupling of HF, I did not think of this issue before, but I guess I will find out if is an issue. If the first prototype actually cuts any audio into a blank, I will be more than happy. And James, are you talking about a pretensioning of some sorts on the pushrod? I'm not real...

I've just got parts for 2 stereo cutterheads today. One printed in alumide(the shiny one), which is noticably stiffer material than other, printed in regular polyamide.

Got the lathe setup properly and cut some silent grooves and test music. I did not hear stepper motor noise on the groove, it is below the background noise.
And some grooves with audio:

I'll do some test cuts tonight at different LPI settings, for checking the stepper noise. I have this 15€ USB crap microscope, I will upload some pictures of the grooves.

Hey. The profiles are 40x40 mm, ordered them at www.damencnc.nl.

You could attach a wheel knob, but I don't think that it would produce a smooth motion.

WP_20161207_15_55_15_Pro.jpg WP_20161207_15_55_10_Pro.jpg CUTTERHEAD V4.jpg I am still debating on the platter problem. I could get a SP10/SP15 and be done with it. Or make something of my own. Anyone knows if these kind of acrylic hifi platters are worth investigating? http://www.acrylteller.com/A...

Hello everyone! I am in progress of developing an overhead lathe using only standard parts and 3D printed parts, as I do not have easy access to a machine shop. Nor do I have a 3D printer, but as of now I am using the materialise 3D printing service. I started looking around on ebay, and bough mysel...

Hello everybody! My name is Wim and i'm from Belgium. I recently acquired a rek-o-kut overhead with An M41 Head, and i am Learning the ropes of the cutting art on it. I'm Using It with a sl1200 turntable with torque mod, and am currently finishing a control box for variable vacuum and needle heating...
