Choosing a suitable motor housing / pod ?

[ytome]

This is my first post/thread and although i have been following the forum for some time now, I only just registered; hoping to contribute and learn and get a discussion going on a topic that (I believe) hasn't been explored enough. So if you think that this thread is a repetition or not suitable please let me know.

I am in the process of building some turntables using old parts. My intention is to keep it as simple as possible and gradually improve aspects of their design and components. Despite any changes in my plans I would like to stick to some initial principles:
-Belt driven
-Real solid wood for base/plinth
-Budget conscious
-visual elegance

Although there are numerous interesting threads on DIY turntable designs I have never came across one that discusses how to build or source a suitable housing for a stand alone motor. I.e materials that can be used or things that should be avoided.

I am currently using some Rega (Premotec) and Pro-ject motors mainly because they were easy to source and work with. My intention is to find/build a suitable housing for them.

The sub platter will be mounted close to the edges the wooden board (I don't want a big distance between the subplatter and motor) and the motor housing will be either sitting on a separate platform or on the same granite surface as the wooden board.

I would imagine that the Housing should have a substantial mass to absorb the motor vibrations. For suitable materials I am considering aluminium and/or stone/granite. I guess it should have the shape of a cylinder but if it proves too difficult to source I could do with a square or rectangular shape (using aluminium project boxes or putting together granite tiles?). I have also considered using a stone ashtray I have (cube shape, hollow, with a small hole at the top) adding some extra mass on its base.

I was also thinking to place the PCB and on/off switch in the same housing. Does this sound a good idea?

Any ideas on motor housings would be really appreciated even if not suitable for my project. I am sure that they would attract a lot of interest.
