I'm putting a shelf in a closet (and closet rod). It's 80" wide. I'm concerned about the shelf sagging. I want it supported at the ends and the rear only. I don't want a mid support.
I was thinking of making the shelf out of solid 1" x 12" pine and supports out of 1" x 5" pine just like in This Old House video.
Using the Sagulator shows excessive sag with these inputs:
- Shelf Material: Pine, Eastern white
- Shelf attachment: Floating (not attached)
- Shelf load: 50 lbs Center Load
- Shelf span: 80"
- Depth: 12"
- Thickness: 1"
- Edge Strip: None
- Sag: 0.43" total "EXCESSIVE"
But, this doesn't have the rear support like in the video. With the rear support, would 1" x 12" x 80" have "ACCEPTABLE" sag?
Thanks.
