In this one, I dovetailed the two sides and the bottom piece together. I also cut the dados in the side pieces for the upper shelf.
I don’t have any pictures of the dovetails in progress, but they’re just your standard through dovetails, gang cut, coped out, and cleaned up with a chisel.
I did, however, get a good set of images for how I made the dados.
First I mark out the dado with a knife on one side (only one side first), and chisel to make a knife wall.
Next I saw down to depth using a back saw.
I chisel a longer slope into the saw cut side.
That longer slope allows me to hold the shelf against the other wall, and then mark the second one off that width easier.
I knife, chisel, and saw the other wall the same as the first.
I chisel out as much of the waste as I can. Bevel up as far as I can reach first.
I use bevel down and a mallet to go the rest of the way across. Make sure you stop just shy of the other edge, so you don’t get blow out. I come back from the other side to finish it off.
With the bevel down, I clean up the dado a little more by just shaving off high spots with the chisel.
Then I finish off with my router plane.
I number the dado, and call it good.
