IF you want to use the two 1/2" plys, rout out matching 1/8" wide groves

He's putting it on edge--the strong dimension. For this to work well
you will have to have the depth of the grooves at pretty close
tolerances.

Actually, using epoxy to seat the steel should eliminate this concern,
shouldn't it?

Perhaps, but I don't think I'd count on it for long term...I suppose you
could fill the groove sufficiently, but my experience is that epoxy and
smooth metal surfaces tend to separate w/ age--or maybe I'm just
unlucky....
