I just tweaked the Gyrodec again, 8mm diameter by 3mm sorbothane glued to 1mm thick rubber place on the top of each suspension pylon and then the supports for the chassis (the threaded adjusters that the springs are normally on) fitted over them. This is to try and get some form of decoupling of the chassis from the legs which are attached to the pylons through the spider. Also my feet sit on small indented discs, I have glued some 2mm rubber under these as well.
Listening tests are that initially things sounded a little dry, then after listening to a few tracks I realised what has happened. There is obviously some form of better de-coupling due to the sorbothane/rubber in the pylons, the result is that there is less microphony (feedback) going on through the chassis enhancing and colouring the music. So bass is more defined (less bloom), overall more clarity and separation.
So a positive result. Not perfect, tapping on the shelf with a record playing still induces a noise through the cartridge, but I would estimate a 50% improvement. The only other thing I can think of is to replace the Gyrodec metal feet with some form of rubber feet, possibly firm sorbothane. I am going to search for some that may be a similar height and could be fitted in some way to the pylons.
Listening is the act of aural discrimination and dissemination of sound, and accepting you get it wrong sometimes.

I know it's a bit out there, but what do you think of speaker spikes embedded in sorbothane hemispheres. I'm waiting in anticipation for parts from Peter to work on my Odyssey deck. I tried the odyssey feet into speaker spike protecters for wood floors. All this on top of a granite bass. Marginal difference but a solid base to work from. I'll keep you updated if you like. Kind regards. T.
As I understand it the key issue is to stop vibrations getting to a turntable which will colour the music, most noticeable with low frequencies. If your Odyssey sits on a solid granite platform then it is pretty likely to be free from vibrations unless possibly it itself sits on a wooden floor which is subject to movement. If you need to de-couple it more then I would talk with Peter about rubber feet.

making skateboard feet using the post off the original feet , buy the skateboard wheels off eBay ,£avrage is £9 , a V-Bush Shock Solid Rubber Mounting Absorber Dampener ID 9mm OD 23mm L 16mm, cut in half , and fit to hole in the center of the skateboard wheel , they will go in with a push , open the hole out , it need to be a tight fit or the Michell post will fall straight through , the with the Michell part fitted screw to the deck , now on the under side on the wheel fit the 2nd part , all the way into the wheel to stop the michell post pushing all the way through , you can super glue this to stop that happening ,
