Decoupling a motor/bearing or both ?

[Wakefield Turntables]

I'm contemplating a new plinth build in bamboo and has decided that I'd like to decouple the motor from the plinth. I'm thinking about mounting motor and bearing on some threaded rod so that I can adjust height of both easily. I'm also thinking about decoupling the bearing as well. Would this give me any additional benefit, or is decoupling the motor on it's own better? I'm also toying around with the idea bracing the bearing to the base of the plinth. I'm perplexed and really would like some help!

Decoupling from what? You want to decouple the motor from the bearing and you want to either decouple the bearing from external vibration or alternatively couple it to a vibrational “earth”, like a big lump of slate or a CLD plinth assembly, but you don’t want to decouple the bearing from the arm.

Yes, I agree.

I'm sure it's been tried though.

Thanks Shane. I was just going to decouple the motor. It is always very comforting gettings opinions and views from those with superior knowledge.
