: Yes, Someone feel free to correct me if I'm wrong (I know you will) but
I believe there is more glue surface area. Just tapping the pieces together
dry will hold them together somewhat, not so with a butt joint obviously
I've handled many panels of different species of spruce & have had butt
joints crack especially after drying. Wood tends to do what wood does, bend,
twist, etc., especially at the edges & butt joints seem to be especially
susceptible at the edges. That being said there is nothing wrong with a butt joint
when good joinery, adequate glue and clamping pressure is used.
Also Sitka panels are not as floppy (Usually) as say softer eastern spruce
or engleman.

Are you suggesting tongue & groove edge joints make for panels that are
stronger than those with a good butt joint? If so, why?

David, Sitka panels that are tongue & groove construction such as the ones
John & Rick Wheeler make are very strong even without ribs.
