Quoted from Steve_in_Escalon:IMHO, the cabinet would be stronger as originally designed. While biscuits are convenient for alignment, the actual surface area for glue is reduced. Using the correct glue with the proper clamps will result in a structurally sound cabinet.

I guess we would have to mock up some joints and test them in a press to see at what PSI does the joint fail.
On all the ones I've repaired, its not the glue that fails, but the soft tongue of the wood just breaks off.
Next time you repair a split cab, take a look how the joint breaks.
The Spruce Pin Fir plywood used originally was 5 core.
If we used 13 core "Baltic Birch" plywood, it would be 4x stronger than the SPF plywood that was used by Williams. It would also be twice as heavy and probably 2x the raw material cost (so maybe $40 more at the end of the day, plus the additional shipping charges). I would have total confidence in the strength of a loc-joint in Baltic Birch.
Would a heavier game be seen as an advantage to anyone?
They also make SPF plywood with a thin veneer of MDF so you just prime and paint with no sanding needed.
