Topic tags/keywords: plywood load anchoring

Hi there- I’m designing a rack to be built with 3/4” plywood- Here’s a screenshot for reference:

I have done some searching through the forums and online but admittedly don’t know the appropriate terms to describe the load that will be evenly applied across these two hooks in vertically oriented plywood. I estimate 30lbs will likely be the maximum load applied, but I want to overbuild for say 50lbs sustained load over the long term. The current height at it’s narrowest point is 1 1/2”. I am thinking about increasing this to 2” or 3”.

I am looking for a bulletproof width of plywood (not the 3/4” thickness) to accomplish my desired 50lb rating. I am also interested in anecdotes, resources, any terms to describe what I’m talking about, and other advice on anchoring the edges of plywood- what are your favorite methods? Screws, dowels, biscuits?

Thanks in advance.

So for 30-50lbs I would estimate that the bottom of your hook should be 1 to 1.5 ”.

For that weight dado and aliphatic glue and screw OR
Sliding dovetail and glue, no screw.

or glue and pocket screws.

Jeff, thanks a lot for that.

Is it experience, or is there a way I could make an estimation like that in the future?
