I'm thinking in terms of something for primarily facing slabs of

Sources, plans, options?
Some day, I'll take the time to read the question first. g
The best bet is to make a drum sander. Dunno 'bout CNC for that.
Djoutube is your friend.

Thanks.
I'm going to talk with him about CNC and a router rig.
CNC is probably not necessary , except in a very basic sense .
I'm thinking along those lines. Simple XY functionality, Z can be
added later if necessary. (Yes, I am aware of the "How often do you
use it now?" issue vs "If I had it, I'd use it more.")
Move router
to limit switch in Y , which trips the X axis to move a preset
distance and
send router back , where it trips a limit on the other end .
Biggest
problems I see is overall levelling of the whole assembly
I see an issue in making sure the slab and the router path are
kept parallel for some value of parallel.
and keeping the router in tram - you'll want to use at least a 3" or
bigger flycutter type
Which leads up to the next question - where do I get one - router
and cutter? I ask rhetorically - when I need one, I'll find one.
First I have to convince Raabobo that they need this.
cutter . The big CNC router systems in use in cabinet shops can
shave a 4' x 10' piece to within a few thousandths .
Here's an ebay auction for an insert type cutter

These are usually used to clean up the spoil board that goes between the
vacuum table and the workpiece .
Routers with 1/2" collets are pretty common , if not cheap . I like
Porter-Cable , last I used that kind of stuff they were pretty good - 2 hp
minimum . A 3 point support under the slabs can be adjusted to get close to
parallel , all those big routers have adjustment in Y so you can make a
slab flat in steps .
