Jeff Sounds okay. If in doubt, add a couple of 1/4 by 1 inch stringers or 1/8 by 3/4 hardware store aluminum on the inside and run a 2" wide carbon strip (tape) over those. You could also use insulation foam as your mold, with stringers imbedded in, glass over and then melt the foam out with a solvent.
