Default Why does a spoil board need to...

be glued, screwed, stapled or otherwise attached to the plenum? The part you're cutting is held firmly to the spoil board with the vacuum so why wouldn't the spoil board also be held to the plenum?

I'm asking because my next machine will have a phenolic plenum and it seems time consuming to attach it and deal with the associated issues when the spoil board gets thin and needs to be replaced.

It does not, big iron CNC's just drop one on and go (change out as needed).
But if you are not running your vac table all day your SB may get mis-shaped, move and cause problems.
