Lovers of records rejoice! Did you know you can cut your own vinyl using something called a record lathe? [Beau Walker] just put the finishing touches on his 3D printed record lathe, and the results speak for themselves!
A Recording Lathe was once used for cutting records, and previously, wax cylinders – if you want to get really old school. [Beau], being an analog lover, decided he had to try making his own. He designed the whole thing in FreeCAD and got 3D printing. A single stepper motor drives the lead screw which moves the writing head back and forth as the record spins in place. As to not waste materials, he’s reusing old CD’s for his newly created vinyls. Two 25W speakers cause vibrations in the needle to cut into the disc, via a clever little mechanism.
The system works pretty well, but he wants to replace the turntable with another stepper motor for finer control of the recording — sometimes the turntable slows down during recording under load which messes up the sound. There’s a video of it in action on his site that we can’t embed here, so you should definitely go check it out!
Of course you could skip the middleman and go straight to 3D printing your records…
