Turntable Isolation

thingiverse

When spinning my turntable at high volumes, the bass would create a feedback loop that caused the needle to jump off track. I could even start the feedback loop by tapping on the carpet, which was quite frustrating. I tried several ideas and suggestions before stumbling upon a comment on an online forum. Someone mentioned that in the old club days, they used rubber bands on ashtrays to support their turntables. This sparked an idea to create something that I could attach rubber bands to for added stability. After experimenting with different configurations, I was able to eliminate the feedback loop. This project has two main components: a main support area with mounting points for the rubber bands and a leg extension that sits on top of them. Depending on your turntable's feet and weight, you may or may not need the leg extension. However, standard envelope rubber bands work well when doubled over and stretched only at the point where they're placed over the mounting points. This allows them to fit snugly while still maintaining their springiness in the middle. You'll need a minimum of two rubber bands crossing over each other, but you can add more if your turntable is particularly heavy. I designed this project using Tinkercad and you can edit it online at https://www.tinkercad.com/things/c8gwPRPkMCk.
