Can one laminate an MDF panel to plywood and still maintain dimensional stability?
I'm building a 4' x 2.5' desk primarily out of maple (I intend to use either cherry or walnut for trim) and for the top I'd like something thick and heavy. Veneer core plywood is an obvious candidate for the top but it will be neither thick nor heavy enough. My idea was to laminate the plywood to some MDF and then use hardwood for edge trim. My concern with this is that despite the stability of both the MDF and plywood, laminating them together will cause problems with warping.
An alternative would be to build a frame similar to that of a floating shelf and then attach the maple plywood to the top of the frame. I have no objections to this but it's significantly more work.
