The mounting plate the rods are welded to that the screws go thru,

I thought the whole idea was it was invisible. Jut a rod terminating in
a single screw, all inline. If there's a plate, surely that's visible?

Not if you make the shelf thicker than the plate is tall it isn't, no.

Surely the shelf can only be an inch or so thick or it'd look ridiculous.
That's not enough to give leverage to a bracket.

The single screw inline would function the same way with roughly half
the bearing capacity altho one could have larger screw which would have
more holding power.

Again the load would be distributed along the rod and and the moment
introduced would end up in _mostly_ tension on the screw.

That could be done with a smaller flat collar (washer) flange welded to
the rod for some bearing support but unless machined a flat or other way
to grasp would be much harder to mount than the screws and a small plate.

The LV model is for 1" thick shelf with 1/16" of material left
above/below the plate for hiding it which leaves 7/8" for height of the
plate itself. Needs about that much for enough bearing room for the
screw heads for a #8.

What's missing and does limit the load capacity to what the screw
holding power is is that there's no 45 brace of any sort here to relieve
some of the moment arm from the bracket screw.

Indeed. Which is why I just use a normal bracket. It goes 6 inches down
from the shelf and has a 45 degree brace.

And looks much worse than a floating shelf.

It looks like a shelf, instead of some new age **** out of star trek.
