My benchtop is 2" of MDF sandwiched b/w 2 3/4" ply. The lamination went well, and I'm starting to attach a skirt around the whole thing. Noticed right away that the end of the new top that has been hanging off my old bench is already sagging. So obviously I'm going to have some problems. The new top is only 19" wide, as the skirt width brings it up to 24". I cannot have an apron for support because it would make the face to thick for clamping to the surface. Any ideas on support? Would it make sense to run a couple metal bars underneath the length and width? I'm surprised and really pissed off that the MDF in the middle is sagging already. I thought the ply would support it, i guess i was wrong.
Maybe a simpler question would be do you think my skirt/edging would serve as support enough? The skirt is 2-by material glued up to form 2 1/2" wide edge (2 pieces on end). I think that may keep it flat front to back, but the 50" span between legs is my concern.
