Whilst I'm here I thought I'd post a pic of my own turntable.
It was a quick lash up so I could get my SME back into service. I glued several layers of Dibond together and cut out a rough shape on the bandsaw. A Clearaudio platter and bearing do the revolving bit and a Maxon dc motor and my own psu provide the motive force. Three Discs of Silence from Solid Tech seem to provide some reasonable decoupling though the springing is a bit too stiff. I'm part way through making another subchassis, this time from thin birch ply and aluminium layers with a purpose designed suspension rather than just sitting on the Discs. Hopefully I'll get some improvement in performance though I'll be happy if it just looks a bit better.
