A Copernican View of the Turntable System

Raul,

Thanks for the warning. I did spend an inordinate amount of time ensuring that both armtower/arm and tt were levelled exactly the same, within the limitations of the small spirit level that I use for this purpose. If I can find an even more accurate method/tool I will definitely try to make it even more exact if possible. If you (or anyone) have a suggestion of how to improve on this, it would be gratefully received.

Thanks again for your kind help throughout

Dear Dgob: I'm not expert on levels/vials but maybe a digital one could help and with high accuracy and easy to use for that purpose.

regards and enjoy the music,
Raul.

Dear Dgob,
Wonderful post and illuminating descriptions.
For newcomers to this thread and the sceptics out there, it would be good perhaps for you re-cap on what plinth you had used with the SP10Mk2 prior to 'nuding' it?

Raul,

Thanks. I'll look into a digital option.

Halcro,

Thanks for the kind words. Regarding the plinths tried, I tried a birch, aluminium and acrylic composite plinth. I also tried various directly coupled arm boards. These included ones made of birch/aluminium, ash and MDF.

Of the armboards, the ash was the best performer (in view of the achievements and criteria that I have used for the nude approach). The bespoke plinth is of my and my artisan brother-in-law's design. It performed well but the experiment with the nude and stand-alone approach has meant that we're back to the drawing board and trying to see if we can incorporate some of the apparent lessons into a new design.

This is only an exercise to see what is really possible (plinth wise) for those who MUST have a more traditional arrangement. However, given financial and time constraints at present, it might be quite some time before any advances are made on this front. When they are and assuming that the results are worth noting, I'll definitely feed back.

In truth and thanks largely to your and Raul's initial suggestions, the nude and stand alone approach are (as I've sought to explain) all that I could wish to achieve.
