I needed more storage, and found wall space to squeeze in a 24" x 42" cabinet in Doug Fir. I started with a 2"x10" that I resawed into 1" and 1/2" pieces. The 1" side became the dovetailed carcass and shelves, and the 1/2" side became a shiplapped back. The bottom shelf is fixed in a rabbet and the upper two are adjustable. No doors at the moment, I'm thinking about that, not sure I want them.
I'm happy to have something that is solid wood rather than plywood and MDF. I put a home brew boiled linseed oil - Mineral Spirits - Turpentine finish on it, followed by paste wax. I've blogged about this build previously, in Glue-Ups With The Right Clamps Are Boring and More Efficient Dovetails.
I also used a couple of the 1/2" resawn pieces to make some "Redneck Plywood". Never heard of it? It's cheap and strong. I had two 1/2" pieces left over that were in sad shape, full of checks and knots, and warped all to heck. Normally you would throw these away. Don't do that - glue them together and glue a 1/4" strip on the front. Makes a great, cheap shelf, and you can't tell it from a solid wood shelf.
For now, it is being used to store some of my hand planes until I get the plane cabinet built, hopefully this summer.
