Kitchen Island Overhang

What WOW said...My very first thought in about 2 seconds was a square tube steel frame.  even mutltiple smaller ones so the diameter can be smaller,.  No need for a 2" tube if you have 5 or 6 3/4" grid pattern.

Not sure I understand where the steel frame would go. Can you explain in more detail?
I didn't use a 2" tube, it's 1/4" flat stock that's 2" wide...

As I understand, there is a continous piece of 3/4 ply between the steel brackets and the quartz.  I am assuming the ply is continuos over the cabinet as well as over the brackets.  If that is so, I think it will take a lot of abuse.  Mybe not for a three hundred pounder to try dancing on the overhang, but normal elbow leaning.

All stone has a grain to it.  Some the grain is in layers, as with sedimentary formations such as slate.  Those stones will withstand forces that want to make it bend. The damage would not be in a snapping off along an angle from the support base.  Quartz is formed differently and is more granular in its makeup.  The grain is more vertical and a crack can occur anywhere.  The crack might not be there before, during or immediately after installation. It might never crack, but the possibility is always there.  Many marbles can be subject to breakage.  I have handled fireplace facings that were as fragile as egg shells with their crazy grain texture.  Granites are less veiny and more like concrete in strength and texture.

I am not a geologist and do not know the terms to describe what i say above.  i just know what i have observed thru working with the various materials.

I have another funny story about wring with marble.

I had built a marble fireplace with a serpentine wall in "S"curve around the corner from the fireplace face.  The face of the fireplace and the "S"curved wall were in strips of about 4 to 5 inches from the face to the back (inside against the backup masonry.  The wall was free standing with a cement grout covering the rough backside of the wall.  It took a lot of very careful chipping away of the curved pieces which varied in heights from 2" to 7" or 8".  The hearth was in the living room section and raised, i think about 12" above the floor.  The entire structure wherever shown was Tennessee Cragmar pink.  the hearth I had cut special to my specs.  When it had been cut, they called me to come pick it up.

I had two helpers at the time.  one had been with me for several years, while the "new be" had only started with me on that job.  I sent the "new be" to pick up the stones with specific directions on how he should protect.  I knew the craftsman who had cut the stones would make sure they were well protected before he would allow the driver to leave his shop.

When the driver came bak, I was right there to make sure the stones were not damaged, either in transporting or, of even more importance, in the unloading.  As we started unloading, my long time helper started laughing. i inquired why he was laughing.

"if you had gone after those stones, you would have been a nervous wreck by the time yyou got back here.  you would have been on edge for the rest of the day, even if no damage.  You knew that if i went, and a stone got broken, you would probably never see me again.  you knew that Pete doesn't know you that well and he would at least show up if a stone or two got broken.  he might not have lived, but he WOULD have shown up."

There were no stones broken.  ::)

I do think your job will stand the test of time. You have taken all precautions yu could to make sure it will hold up.
