Anyone out there install a 90 degree bay without framing to the ground recently…I have a project that is calling for this, but everyone (read supplier) is losing sleep over whether or not cables and angled support framing will hold the overhang (approximately 24 inches). The client has a garden underneath the location with southern exposure and does not want to give it up (small yard) but also wants her bay to sit in (eat in area of kitchen, bay will act as bench seat for informal dining). I am thinking heavy header (microlam) on the 6 foot r.o., double jack studs, double sill plate, cables in the corners of the unit and 45 degree angled support framing (2 x 6) should cover all the bases. Any thoughts?
Thanks, Bill

Bill, I installed an Andersen box bay like that a couple of years ago. My advice would be to use double king studs (and double jacks for 6'-0"). Make sure you have access to the tensioning cables, and yes, definately use the cables. You should be ok without brackets underneath if you follow the mfr's specs, but it wouldn't hurt to add some extra framing under the bay in case you decide to add brackets later.
*I just repaired two such bays in my house that were sagging enough to keep the side windows from opening.The house is stuccoed. Wooden bay units. I had the stucco below the window hammered out to locate the lower wall studs. Then my local welder came over and we designed a bracket having two vertical pieces of 5/16 steel welded to connecting plates on top (under the bay) as well as towards the wall. The ones towards the wall were long enough to span across 4 studs.Predrilled holes through the wall plates and into the studs. Made sure the felt was good on the wall. Then jacked up the bays and positioned the brackets in place. Lag bolted them into the studs. The plasterers filled in with lath, browned, scratched, and finished to match. The carpenter then finished off the bottom of the bay with masonite and paintable redwood trim. Primed, caulked and painted with a good oil enamel.From the outside the brackets are barely visible. Plenty of room under for flowers and herbs. Ain't ever going to sag again.The welder charged me $75 for the brackets.
*Do these brackets have a diagonal brace on them or are they just "L" shaped?
*If you are responding to my brackets, When I referred to the 5/16 vertical piece, it would be interpreted as a diagonal looking from the side view. It's plenty strong.
