Realized: Twistable Fans
This is my first version of a usable twistable shaft for vibraphone fans. The concept enables the use on most vibraphones (e.g. Musser M55) for a more or less DIY-self-adaptation as a retrofit kit while continuing to use the existing drive unit.
But it took a rainy November weekend to fit the fans and coupling elements together.
That's what I've been looking for for years.
