The Secret Society of Lathe Trolls

Great idea! Looks great, creatively in keeping with the theme. And yet another way to place the record. I like it that way.

THX for over (unbelievable) 5,000,000 views It was almost exactly three years ago that I started my project. I started reporting on it (with a delay) in July 2022. In the meantime, I have presented over 600 images and numerous videos and audios. I work on the project (including research and investi...

GROOVE DEPTH CONTROL - SUPPLEMENT 11/2023 I wanted to find out a little more about the GROOVE DEPTH CONTROL before I got down to other (more important) things. And also because I claimed that changing it too quickly would result in a noise that doesn't belong there. And so I asked myself whether I ...

I checked the videos!
Nice work!

Really nice as always ! Thanks to this forum there are some informations about the principle behind this kind of groove control mechanisms, but I never thought about how changing the depth too quick would cause an audible frequency by example. Now that I read it it seems obvious. So thanks for shar...

Dear Lathe Trolls, My academic paper ... ...Finally, thank you so much for being so open and sharing information with me so freely (via email, zoom calls, phone conversations, etc.) – I very much hope I can give something back by highlighting your contributions to keeping analog audio disc making a...

Suspension box FP-9 11/2023 The suspension box has now been reassembled. It now contains the mechanical lowering mechanism with lever and latching function. It also contains the mechanical and electrical release so that the cutting head can be raised again. Secondly, the coil for the GROOVE DEPTH C...

... But your solution with variable depth... Is this something new or did I miss some information? Has anyone already implemented something like this? ...is nothing new. But rare. It was already used in old Neumann lathes. I think it is very rarely used in the DIY sector, which is why there is so l...

I think we should all hold a minute's silence now. When something painful like this happens, it's like a punch in the gut, you have to put your hands to your head and pull your hair out (if you still have any). But tomorrow is a new day and God willing, one day the sun will shine again and you will ...

Great development! Supposed printing time in half the playing time.

GROOVE DEPTH CONTROL (GROOVE DEPTH CONTROL) Suspension box FP-9 11/2023 As I am currently working on the suspension box, I would like to add another element at the same time. My plan from the outset was to install a groove depth control in the suspension box. I planned to do this without knowing ex...

Suspension box FP-9 11/2023 I also had to go back to the lathe for the mechanical release. I made this screw-on operating knob from brass parts. I knurled the screw part to tighten it and then polished the parts to a mirror finish. . . 66_01.jpg . . Add the matching spring and the push button is fi...

Amazing stuff as usual ! Can't wait to see (and hear) the tests of the new head. I noticed that you put some plastic/rubbery tubes around the pushrods and torque tube, I guess it is to dampen the high frequency resonnances of those elements ? From what I understood that's what the rubber on the pia...

Suspension box FP-9 11/2023 Next up is an even bigger challenge when building the suspension box. I have to rework the eccentric for the lever mechanism. Instead of just a manual lever movement as before, the new body will also have an electrical and a mechanical release. An unlocking mechanism tha...

Suspension box FP-9 11/2023 Because the new cutting head is now not only smaller but also lighter than the old one, both the counterweight in the form of a spring and the oil damping have to be adapted. To do this, I machined the piston and added additional flow-through holes. . . 64_01.jpg . . 64_...

Great long run

New CH-9 cutting head (part 7) 11/2023 Now I was finally able to assemble the complete new FP-9 cutting head. Driver coils, feedback coils, torsion tube with V-spring, suction tube, stylus heater, lighting and connector plugs. . . 63_01.jpg . . 63_02.jpg . . Then I installed the cutterhead as a tes...

Hello my new lathecut trolls friends! Perhaps nothing new for you, but music is my passion, i love sharing it, lathe cutting is my new one, i'll do the same :D So here's the start of my homemade lathe ... Ah, a Barthe Rotofluid Disco 2 from the 80s. Rare but robust metal housing if I remember corre...
