WOOD - How to "assemble" a good sound-board?

[J D Sauser]

I've worked with wood all my life from childhood on. Building furniture, a water wheel, model air planes...

I on the verge of ordering a pile of Paulownia wood to make a sound board for my next prototype PSG.
The sound board will be thick as to include what we perceive as the neck, similar to a Fender PSG.
So, I am not assembling a "plank" but more like the soundboard like seen on lap steel.

I understand that one would ideally glue several "sticks" of quarter-sawn wood.
My question is, HOW to you arrange their assembly... looking at how the cross section "partial radiuses" face each others?

Thanks!... J-D.
