The Secret Society of Lathe Trolls

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...

Hello rcvinyl,
I received the stamper today. It arrived safely and is beautiful. Thank you very much!
Thomas

Hello Thomas, just popping in to say this is all very impressive! I'm lost when I try to actually follow what you're doing, though quite interested in following along and learning more about it. It's too bad I only got my first lathe late last year - I was a vendor last spring at Fanzineist Interna...

Tout ces travaux, essais partages sont magnifiques et m'inspient beaucoup ! Merci

Bonjour Sebastian, merci beaucoup et bonnes salutations en France

New CH-9 cutting head (part 6) 10/2023 But now on with the cutterhead. As an alternative to the external suction tube, I would like to try a suction tube on the cutterhead. The disadvantage is that central positioning is not possible and the cutting thread has to be sucked off slightly to the side....

Hello Thomas. I see significant progress in your project. Glad to see you still have the energy and drive to continue. I agree with you that many here read more than write. And without feedback, many enthusiasts quickly burn out. And since I write quite rarely myself, I will correct myself. After a...

Hi,
The reason for cutting inside out was ...
Mark

... and I've learned something again! Thank you Mark!

Hello Eugene, it's so nice that you can come back. I follow the situation in Ukraine every day and thought it would be difficult for you to continue. It's all the better to see you back at work. I am looking forward to seeing the next steps of your project. All the best and greetings from Austria Th...

...I am a lover of 7-inch singles at 45 rpm.... ...As is known, in a cutting recording, as the end of the record is reached, the spiral becomes narrower and therefore the separation of the grooves as well. .. This means that the low frequencies are present, but the high frequencies are not in the s...

Lesson on loudspeakers and drive coils 10/2023 I have learned. What I measured and what my opinion is: In my post here are already quite a lot of hits and therefore I assume that many trolls follow this post. This also increases the unpleasant feeling that I am responsible for not writing nonsense ...

Here’s a punk rock test cut and playback (video)

Your lathe looks great. The lighting reminds me of a mixture of steam punk, flux compensator and a ventilator from a heart operation. All in all, a fantastic journey back to the future.

New CH-9 cutting head (part 5) 10/2023 After the lighting has hardened, I can test whether the thing fits into the cutterhead. The shape and screws fit perfectly! - Lucky. . . 60_01.jpg . . But there are still a few other parts to be made, such as the retaining bolt with which the cutterhead is lat...

Here under the cutting head

Hello Chany, I have answered you in your post "Presto k8 /cnc motorized harm.".
Greetings Thomas

Hello Chany, I'm replying to your post here about PetG and VCA. Your cutting head looks good and the way I see it, your cutting pin is sticking out way too far from the torsion tube. if you mount the pin further in, you would have a much lower VCA (25°). However, I see the problem with the suction t...

Here’s my angle and set up Hello Chany, Your lathe construction looks very interesting. Especially the long carrier arm with the spring-loaded lever arm. Does the small stepper motor drive a counterbalance or does it lift the carrier arm - or does it do something completely different? The cutterhea...

New CH-9 cutting head (part 4) 10/2023 The "old" cutting head had lighting, but it was not satisfactory. We would call it "glowworms". That's why I planned really bright lighting for the CH-9 and incorporated it into the design. As the head is a lot smaller, it was a bit of a challenge because the ...

An excellent article on the subject of rake angle and VTA by J.I. Agnew: Vertical Tracking Angle Meets Stylus Rake Angle https://www.psaudio.com/blogs/copper/vertical-tracking-angle-meets-stylus-rake-angle-part-one Accordingly, the rake angle should not exceed the 2° mark and must be taken into acco...

... but the overall angle in relation to the disc (so in this case I guess 90+7°) Correct. About 90+7°. (in this case the rake angle is +7°). As far as I could find out, this angle is almost 0° or slightly more for DMM on copper. For cuts in lacquer at 1° to 2°. For cuts in PetG or PVC over 2°. Som...
