Thank you for your reply's. I am interested in those subjects that I have little or even prejudiced knowledge of.
Last night, I read a bit about the Super Scout Master by VPI. Incredible design, save for a problem of even energy transfer from the rim idler (fly)wheel to the platter. Seems that rubber to rubber has it's own issues, in that each rubber surface must be perfectly flat and even. The most interesting part of this was the solution to the vibration being transferred. Replacing the isolation feet on the TT, and using spikes, allowed the TT to be a more solid (immovable) object compared to the externally mounted motor/flywheel arrangement. This forced the the vibrations back to the origin enough to be of minimal effect to the TT.
I will be reading about some other related designs in the near future. There is much more here than I had imagined.
