Hey y'all.
New to the forums here and I've got a technical question. Hoping this is the best avenue for it; if not, please point me in the right direction and I'd be happy to repost elsewhere.
I'm hoping someone can shed some light to my problem. I need to install a granite countertop (3cm thick), which will measure 65" long by 59" wide. The cabinet it will rest on is only 34" x 28", constructed of 3/4 inch, birch plywood, and is secured to the floor. Atop the cabinet lies a 3/4" thick, birch plywood spanning 50" x 44" (horizontal). The only real support currently in place is the cabinet (34"x28"). The rest is floating.
This means that the plywood has an overhang of 16" evenly distributed along the 4 sides of the cabinet. And, the granite countertop would have an additional 7.5" overhang throughout on all 4 sides from where the plywood subtop ends.
I'm wondering if anyone knows whether the plywood top will be strong enough to support the weight of the overhang. Since it is a piece of granite, the weight distribution will be nice and even with the bulk of the weight resting center of this island (cabinet).
Apologies for the long post and thanks in advance!
