No trade secrets, a few cabinet suppliers are making them.Willem--Those are as clean an installation as I've seen, especially considering the relative thinness of the shelf boards. If this is not asking you to reveal your trade secrets, could you describe how you attach the shelves, or maybe send a link to Google, You Tube, etc. that has a video showing your attachment technique? Thanks.

In the picture below you can see the frame which screws into the studs in the wall with cabinet screws. The sleeve then slides over and we use a couple of 23gauge pin nails so it does not slide off. At first I was concerned about flexing and load carrying, but they are surprisingly stiff and stable.

I have tested a 2 1/2” thick at 200lbs. Non issue.This is interesting. I'm building some right now. I'm timberlocking a 2x4 on the wall (long face level) and my shelf is a sleeve that slides over that and gets screws. I guess I went a little overkill.
How much weight do you figure this holds? We're going to put dishes on ours.

I use to make the frames out of 3/4 ply, but now use 4/4 Maple as it is actually cheaper at the wholesale prices I get.Is the box 3/4? I was worried about deflection more than anything. We have droopy shelves right now, they don't look great.

The sleeve is 4/4 Maple rails, one along the length and two along the depth cut to the thickness of the shelf. The horizontal panels are two 1/4” Maple ply MDF core.
LOL!! Sorry, but thats funny! Unless youre just talking about supporting the shelves on the ends and not as mounted to a wall....I have tested a 2 1/2” thick at 200lbs. Non issue.
Let me try better EnglishLOL!! Sorry, but thats funny! Unless youre just talking about supporting the shelves on the ends and not as mounted to a wall....
For 10” deep, I do 2 1/2” thick. The frame is 1 7/8” thick and does all the work. That was for this install. If we go 12” deep, we do a 3” thick shelf.Not to hijack thread but out of curiosity how deep are the shelves? I would think after a point they would deflect down in the front unless you go thicker ? But to clarify I have never made one, but thinking about making 2 for a bathroom.
Yea, Id love to see a free body diagram of the load path on that.Let me try better English
Mount frame to wall, two cabinet screws in each stud.
Slip envelope over frame and pin with a few 23 gauge 1” pins.
Place 200lbs (4x50lb bags)on shelf. No noticeable deflection, no failure
That was not a voluntary test, we had a customer who specified that as a condition and he wanted to see that.
What is funny about that for you?
Actually, if you have overseas first year college students, they will be able to calculate that with reasonable accuracy.
That is taught in Strength of Materials 1.

The challenge was yours. But we don’t need a diagram. The maximum stress point is a 3 minute free hand calculation.Yea, Id love to see a free body diagram of the load path on that.
Good luck with thatThe challenge was yours. But we don’t need a diagram. The maximum stress point is a 3 minute free hand calculation.
I am cautious spending time for no reason.
Experience has taught me that those without a formal technical background have no respect for applied math and physics, they believe what they believe.
LOLGood luck with that
