Does anyone have any experience building semi-hollow wood/foam/wood sandwich boards? I've got an idea in mind but I'm wondering on the logistics.

Roy, you might be able to help me out on this one. If I only used two support beams running the length of the board say 1" or less wide and 2" apart could I get all the flex of a sheet of (1/4")plywood to happen on only one face (bottom only) of a hollow board? I don't have the ability to build a rocker setup like you use, so think cheap in your answer. I'd like to have a flat deck and a rockered bottom but I'm afraid the bottom will want to flatten and half the curve will be on the bottom, half on the deck.

I don't want cross beams because I'm trying to maximize flex.

This probably doesn't make any sense to anyone else but me...

Can you draw what you are planning? If you want to maximise flex then cross beams won't hurt as they won't stop the board from flexing. A tapered profile on the other hand (which you will get with a flat deck and a curved bottom) will reduce flex in the middle of the board. Apart from this the most important thing for flexibility is to have a relatively thin board. A timber Paipo will have to be an inch thick or less if it is going to be noticeably flexible.
