Sorry about that guys. I should have taken a camera. I did see a non assembled table, so I will try my best to describe what I saw, as well as what Larry told me of his machining process
The drive motor sits under the plinth, near the back outer edge, but just inside the outer edge of where the platter will end. The motors shaft protrudes up through the plinth, and is therefore hidden from sight once the platter is installed. The motor can be seen if you look under the plinth.
The motor shaft has 4 o-rings installed with these o-rings driving the outer edge of a sub-platter (idler wheel?). That sub-platter is somehow attached to the main platter. I have no more information since I did not see this sub-platter/Idler wheel installed on the main platter. I believe "Direct through o-ring coupling Idler Drive" may be a more correct description?. The motor is decoupled from the plinth with a carbon fiber mat, and the o-rings further decoupling the motor drive shaft from the sub-platter 'idler wheel'. This is identical to 'Christine', with the exception 'Christine' has her motor in the front left corner as opposed to the back left.
The main bearing housing is first installed onto the plinth, but with no hole drilled. The plinth is then bolted to one of the machines Larry uses to make aircraft parts. He first drills an ~1" hole dead center and true. Into this hole he inserts a piece of cryo treated porous Brass. As the brass warms to room temperature it expands. This brass insert sleeve cannot be removed, nor can it move, and is now drilled by the same machine, but different drill bit of course. A small recess was also drilled in the top of this sleeve for two reasons. To hold excess oil for the absorption by the porous brass, and to have extra oil so that no future oiling be needed. Larry told me that while the platter/bearing are seating themselves, you can see oil starting to show itself along the top edge of this porous brass. Cool.
The main platter bearing is carbide steel, with the thrust ball still being experimented with. Do they make carbide ball bearings?.
The platter is as described on his website, multiple layers of material.
The tonearm mount is decoupled from the plinth with carbon fiber, the bolts holding the TriPlanar tonearm (in his demo unit) are decoupled using brass washers.
The motor controller is a thing of technical beauty. There are three speeds, 33.33, 45, and 78. Each setting has it's own seperate fine adjustment. I do not know how many masters where made slightly off speed, but at least now I can experiment.
