I have built 4 carts and my router table using these simple joints. with the pockets for the rails everything lines up with no effort I only need a wallet a drill to countersink the screws a impact driver and glue. I use pocket screws on the outside to hold the top and shelf on so it is very easy to build. took about 2.5 hours from drawing to putting the top on.
this took 6x48 piece of baltic birch and the top. I like to make them in 4 pieces it is so fast but that east up a lot more material.
