Have I just been oblivious? (like that’s never happened before…) @WillAdams casually dropped this in the recent leather-working thread
[Vacuum Table 24x12 - Carbide 3D]
and there is a 24x24 version. I don’t remember seeing this a week ago when I was scanning the store, but I don’t have a Shapeoko and I’ll stick to that excuse… 
Yeah, that was news to me as well.
I wonder how many of those panels the pump can support.
Hopefully, I’m not in trouble for mentioning it — apparently they were showcased at a tradeshow, hence them showing up at:
I was kind of surprised that there wasn’t a size for at least the Nomad 4, but maybe the moving table makes that untenable?
Presumably, @wmoy will do a video on them — looking forward to it!
FWIW, I was gifted an aluminum prototype by @Luke ages ago, which I’ve been using off-and-on (when a cut warrants mounting it and putting up w/ the noise of the compressor), and which I’ve been studiously keeping out of the frame of photos, so glad that is no longer an issue. It works incredibly well, and I’m looking forward to re-mounting it and no longer having to keep it on the down-low.
My question on the vacuum tables has been how you square things up like I have done with dog holes and PVC pipe sections.
Slight side tangent. After seeing people use MDF as their vacuum surface after sealing I was wondering about drilling holes in the aluminum hybrid channels, sealing the sides and bottom of the slats and plumbing different zone. This would provide a table with no sacrifice in Z.
I am sure that is a lot of work and I am not brave enough to cut through my new 5.1 sections to try it.
Maybe there is an alternative to replace the slats with ones that are machined to specifically be for vacuum and plumb from the back or front edge.
I am glad to see the progress in this direction. But like you said the pumps are noisy.
For the record, I’d buy a nomad 4 version
