When I saw Ana's Barn Beam Ledges, I thought they would work great for our living room. However, I was a little concerned about the sturdiness of the keyhole/screw attachment to the wall especially if I made the shelf any bigger.

So using the Barn Beam Ledges and Ana's collaboration Floating Shelves with Young House Love, I created this design. I will note that I have not built it yet, but was hoping for any feedback the community would provide.

I plan on screwing the supports/"skeleton" directly into a few studs then fitting the shelf "shell" over the top of it. I left the skeleton with 1/2 inch of wiggle room on either side of the shell, because I was a little concerned about everything being too snug or difficult to fit.

I plan on using countersunk (sinked?) screws on the skeleton. And for the shell following Ana's plan with glue and finish nails.

I'd appreciate any feedback! Its my first custom design, so I'm open to suggestions. I'll be sure to post pictures when they are completed.

Thanks!

What are the best screws to use when attaching two boards that are 3/4"? 1 inch or 1 1/4 inch screws?
