Re: Stereo Professional Cutting Head and System

bees often flee from smoke ,we old people have enough experience not to waste money on products that are not properly measured and seriously tested by professional hands and measurement equipment approved by the industry. :)

Re: Stereo Professional Cutting Head and System

And one more photo. The aluminum body houses drivers with an output of approximately 2W, 8ohms, 8mm coil diameter, and flat-wire coils. Helium-cooled. Frequency response is almost 30kHz, with a resonance of 2kHz. This prototype head is capable of recording signals up to 20kHz with a falloff of abou...

Re: Stereo Professional Cutting Head and System

NINJA stereo cutter head. That's what we'll call this head. :) The dynamic transducer works, I am very impressed with how it works :) I made the speaker drivers in 2-3 hours, no more [they worked quite well]. This NINJA driver was practically factory-made and took me 12 days to assemble. There's a ...

Re: Stereo Professional Cutting Head and System

and how to solder the cantilever to the drive ? well, with a homemade tool (this photo is not mine) to do induction welding... I repeat, I am not an engineer but I am not normal either and it would be an insult to me if they digested my medriocre mind hahahaha good things about autism.

Re: Stereo Professional Cutting Head and System

another thing.. I am only taking advantage of that part of the "manual" machining to be able to hold it on the lathe, once I have all the measurements with the caliber that will go outside.... and the measurement of the cantilever will be much smaller, around 0.7 mm to which I will put its respectiv...

Re: Stereo Professional Cutting Head and System

in the other photo you show only one piece... My question and what I would do in this case would be to make two pieces to join them later and thus with kapton or another material have the coils ready before assembling, then with some high temperature resin join the two pieces and everything is simpl...

Re: Stereo Professional Cutting Head and System

Look, trolls, and learn! I took this photo of the inside of this head so you can see how a professional 9mm voice coil is made. I'm showing you so no one will rip you off with a head from car speakers, because it's a waste of $3,000... on cat poop... :D Pretty! Looks like a vinilum? The red one ?, ...

Re: Stereo Professional Cutting Head and System

You might consider consulting a psychologist who also understands CAD; that way, you could share the measurements with everyone who is willing to help altruistically.
Time to come back to cutting room. Be safe, be precise, be serius.

Normal people projects.

If you need serius projects please, we need measures, error tolerantes, Drive coil measures, etc... Please dont trash our time and colaborative experience.
Gracias !
