Default Floating Corner Shelf

I'm building a corner shelf to hold a 40" flat screen TV.
I'm going with a floater that will have 1/2" ply on the top and bottom. It will be 24" X 30" and the outside corner will be cut off parallel to the TV screen. I'll wrap the exposed edges with 3/4" red oak. The cleats will be ripped from a S-P-F 2 X 4 and will be 1" thick and 1 1/2" wide. I can hit 3 studs on the 30" length (corner studding plus 2 others) and 2 studs on the 24" length (corner studding plus 1 other) I'll attach the cleats to the studs with 4" Timberloks or GRKs. Is my choice of wood and dimensions for the cleats adequate? Also, instead of rabbeting the wrap boards I'm going to glue 1" thick S-P-F between the ply along the exposed edges....the red oak can be glued and nailed to these. Comments, criticism, suggestions?

All you need is 2 studs on each side for the cleats. Since most of the force will be vertical, you should be fine. Your fastener choice is probably overkill. You need about 2" min in the studs. The cleats could be a bit larger but will probably work ok. You probably will be putting well less than 100 lbs on the shelf including the shelf.

TV weighs 17 pounds. Not sure about the shelf....but fairly light. Should the cleats be thicker or wider?

I just hung up a tv for my Granddaughter in her Moms house. It was only a 32", but I could not believe how light the flat screen TV's have gotten. I bought her a proper wall mount to mount it, but shoot, you could almost hang this thing with two picture frame hooks! I don't think this TV weighed 5 pounds.

good idea...
wall hang the TV and but a shelf under it...
good place for the cable box and DVD player...

This is definitely in the "opinion zone". Like I said before, they will probably work just fine. My own personal bias is to increase the surface area against the wall to distribute the pressure against the GWB. Maybe 2 - 2 1/2". 1" thick is fine. but, you also have to consider looks.

I'm not sure if you and I are on the same page with the dimensions...I have the cleat height at 1" (top to bottom) and extending out 1 1/2" from the wall. I was trying to keep the height down so the whole shelf would not be too thick....with a cleat 1" tall plus 1/2" plywood skins puts it at just less than 2". I was concerned that at 1" tall maybe the cleats should be a harder wood e.g. oak or maple rather than pine. I can also glue a piece of oak to the pine cleat to strengthen/stiffen it.....just to be on the safe side.

Jim structurally you are fine. The shelf could carry 100 lbs on a clear span Pull out on a coarse draw wall screw into a wood stud exceeds 100 lbs

Learning is an exciting adventure

I took a slightly different approach for my two corner shelves...maybe it will work for you...

I profiled 1x2's, put a groove down the middle and screwed them into the studs using 2" screws inside the groove. My triangle shelve piece (1/2" plywood) was cut to slide into the grooves of the two 1x2's (walls are never square). I then profiled another 1x2 for a face and grooved the back side. The triangle shelf sits in all three grooves and has a nice wide piece for front support. Plywood was covered with felt, wood was stained and poly'ed.

The shelves hold a couple of statues (Blues Brothers) weighing about 25-30 lbs each.

Interesting concept. Pics? There is a raised lip around the plywood created by the 1 X 2?
