Goodness no, nothing all that exotic. A simple set of properly designed pre-crowned wood ribs will do the trick. The loads are not all that great. Compression set is much more of a problem perpendicular to grain than it is parallel to grain. A compression load that will turn spruce to pulp when applied across grain will barely faze the same piece of wood when applied parallel to grain. Del
