Beautiful table. Over the course of my audio travels, I've used Schroder and Ikeda arms and loved them both (to be fair, though, I bought Ikeda back in the good days where you had to buy through 2juki on eBay and the cost was 1/3 of the cost with US distribution).
I've still got a few Garrads in the house: a nice 301 refurbished by Audio Grail that I'm about to put in a nice, but quite cheap, plinth and a 401 in a plinth from a known plinth builder that looks a bit similar to your design and cost 15x what I just paid for the plinth for the 301. I've had many Garrads and am not quite sold on some of the implementations. The cost, anyway. I've got plinths, bearings and platters coming out my ears and IMO the worst audio money I spent was the plinth for my 401. Looks good. Beyond that, not worth it.
The Shindo approach, the A23 plinth, these I think have merit in the context of a well designed cohesive system. Like anything else.
