Pro-ject Debut Carbon Esprit Rpm Selector
CAD // 3D Printing
Being really passionate about music, I started collecting Vinyl Records about a decade ago. The record player of my choosing back then, the Pro-Ject Debut Carbon Esprit initially came with very "bare bones" design features:
In order to change the rpm, one would have to take off the acrylic plate, move the belt from one roller to the other and place the plate back onto the player again.
It wasn't ideal to begin with, but bareable for the longest time. I'd just have a "45 rpm session" or just do the "switch" whenever I felt like it. Recently however, I got a hold of a few records which had varying speeds across sides and I was finally fed up with it.
Having gotten into 3D printing in 2020, I made plans to construct a mechanism I could operate without having to lift the platter.
The idea swirled around in my head for about a year, until I finally sat down and finished the design in a few days.
Twist the knob and a set of gears will move a rack, lifting an arm with prongs, which will gently shove the belt either up or down. Additionally an adjusted roller (on the engine) also had to be constructed, since the original piece didn't allow for smooth transitions between speeds. It is slightly elevated in the middle of the groove, thus the belt centers itself about a milimeter, preventing the prongs of the arm to constantly grind against it.
