This photo relates to a discussion on the Wreck about using a T+G
joint for carcase construction and fixed shelves.

The joint was made out of construction grade plywood to prove the
point that the T+G will provide a good joint, even when the material
is not up to the standard normally found in cabinetmaking.

I'm no expert, but would a dado not be stronger? able to
hold more weight? books, etc...

Nor am I an expert... I would think you would have to worry
about shelf sag long before that joint failed.

Definitely will provide a good joint. The problem with construction grade
plywood is that humidity paired with the weight applied most likely will
eventually pull the joints due to warping / sagging unless you supported
somewhere else in the middle or you use short length shelves only of
no more than 24 inches.

There was in interesting point made in a recent magazine article, I
think in FW, about the varying thickness of plywood. In it the author
used a router/shaper slot cutting bit to take off a layer on top of the
sheet goods using a table which resulted in a uniform width similar to
the one produced by Tom and pictured in this thread. This allowed for a
dado to be routed for a perfect fit, also as illustrated by Tom's post.
If it were me, though, I'd put the stepped part on the bottom. No
disrespect intended. The varying thickness of plywood occurs in many
plywoods, including stuff people use for cabinet making IME. That and
voids can show up in expensive stuff like what people pay over $100 a
sheet for.....YMMV.
