The main point is to mount the mech rigidly to something that is heavy and rigid itself. But, for numerous reasons, I would suggest to stay away from plastics - unless forced by budget or other constraints.

Blimey !
Yep have all the parts except the zvn3310 Found a VN10KM so I ran it in the sim and noise dropped to 3 nano Volts.
Need to get this thing built and see how it performs in the real world.

I have taken Granite and glued the Ebony cubes in the corners, and thereupon CD Transport.

I am thinking of something similar. I am thinking of using a wooden box with metal plates for switches, connectors etc. The copper base for transport would be suspended inside the box, possibly by springs.

I was hoping half the plate would be sufficient for one transport. There is a math error in my post about the size of the plate, 1/4" is 0.63cm, so the mass of half of the section of the copper plate is 767gr or 1.69#. I would hope that to be sufficient to dampen the mechanism.

I was going along the lines of what TheGimp said above - mount the mechanism on the copper plate and then use a nice box as a "shell" to support the periphery gear (display etc). I like TG's idea of actually suspending the plate somehow inside the box. If it's done this way will it matter if the box is of some plastic construction?
