Another shelf sag question
I've checked past posts re shelf sag, but I don't think I saw any with as long a shelf span as I'm planning.
We are building a pantry, size 53" x 90". Shelves on 3 sides of the room, 53", 90" and 53".
Here's our plan for the shelving:
- 1x2 cleats nailed into studs
- 3/4" thick birch plywood
- 1x2 stiffener on the edges, glued and nailed (we're painting the shelves)
Shelf depths range from 8" to 16", though on the 90" run, the maximum shelf depth is 12".
Do you think the 1x2 cleats offer sufficient support or would you recommend additional support, and if so, what span?
Also, if additional support is needed, can we use those decorative wooden brackets? But would they need to be notched to accomodate the 1x2 cleats? (We already have the cleats installed).
Also, I think I would need to join the shelves where they butt together in the corners. I don't have a biscuit routing tool, so I was just thinking of using wood blocks or flat metal bars screwed in on the bottom side of the shelves.
Any other ideas or suggestions would be gladly received!
