I have been looking at the Lee Valley hole pattern for their benchtops - it
looks like a 7 3/4" matrix. What I am wondering is, if I were to build such
a top, and box in beneath it and attach a 4" DC to it, do you think there
would there be sufficient downdraft to allow dust-free sanding on the bench
surface?

I built a downdraft table out of 3/4 Ply. Works well for me. I found
the same to be true as Markus.... If I block most of the holes, it can
be used as a hold down using my DC. I did however slope an internal
piece of 1/4 MDF that helps chips and dust slide to the 4" port.

I made one from an article in one the the mags (Wood, perhaps?). Anyway
it's a shallow box with a peg board top. They suggested getting some of
that stuff that you put under throw rugs to keep them from sliding
around. Found some stuff called Hold Plus at the local Wal-borg. It's
a loose mesh so it doesn't block the dust from ending up in the shop vac.
