new cooktop, old cutout, not the usual question :-)
Bought a new 30" cooktop. It will fit in the existing cutout (2centimeter granite), with plenty of support front and back, but will just barely make it to overlap on the left and right (1/8th" on each side). I've received several recommendations re: additional support, everything from "nothing needed" to "epoxy stone or wood strips flush along each side of cutout". Another suggested wood on the underside of the granite to prevent chipping or breaking.
Wood and epoxy seems reasonable to me, but I'm not clear as to whether I should just butt glue it edge to edge with the granite, go underneath, or fashion pieces that will do both (L-shaped to fill the gap as well as have glue surface under).
Anyone have ideas?
