We have a nice saying for projects like that: "he's heard the bell ringing but doesn't know where the clapper hangs" (from the country that brought you Louis van Gaal ). Heard about the thing but doesn't know how to make it work or why it rings. The felt pads isolate vibrations in the vinyl (that's why I don't like Linn/Rega etc sound) and the star earthing direct the -none present- vibrations to the cheap axis where the real vibrations from the vinyl end up anyway. Then carrying it over via a flimsy bridge to the armbase. And then the weights on the end of the thin carbon extrusions. That is worse than a tuningfork. If you think a platter should look like this than don't isolate with felt pads but couple it with a clamp.
Maybe the man knows about machining carbon-composit, but he does not appear to know anything about the basics of statica/dynamica (engineering calculus). For bending strength you need height/thickness, which works to the power of 3 (moment of inertia in a solid is 1/12.b.h^3) It looks nice to the layman, but to me it looks like an exercise in futility.
I just keep thinking: "Why?"
I merely posted it as "interesting" pics - one would need one hell of a lot more carbon fibre (thickness...) to make TT from.
