This thread has been quiet so I thought I'd give it a bump! First off is a photo of a couple basic shelves I mentioned a few pages back, made with 2x scraps and a 1x10 top, roundovers everywhere and then some spray lacquer for a little glow. Nothing fancy but the total cost was only about $10-15 which is nice.
Next I do wanna try something a little more fancy, floating shelves... I picked up a book at the library, "Build Stuff with Wood" by Asa Christiana, which has a chapter on floating shelves. I've attached a shot of his basic plan. I feel stupid asking, this author does seem competent, but are floating shelves really that straightforward? Sandwich solid wood strips between thin plywood, then attach that to a wall cleat? I was thinking I'd miter the corners of the strips to hide the end grain, or attach a thin face of solid wood to the front and sides for a cleaner look with no plywood edges. And maybe softening the corners with a curve instead of a right angle.
I wanna move beyond using just softwoods (though I have plenty of small/thin scraps that could be used for the insides) and work with nicer plywood, and finally put this Dewalt planer I got during Amazon's Black Friday sale into action, since I have some rough-sawn walnut and oak boards to use. So as usual any advice would be appreciated!
