Thank you! I’ve made lots of furniture for the house from some things like this to a six chairs dining set and built-ins.

Great point. The drawer width was taken on a story stick, not numerically. I first made I side spacer blocks and then made a sandwich on the old shelf with a spacer block and a 1" block (each slide takes up 1/2") and then marked off the gap on a stick.

Observant folks might notice that I made the drawers sideways. Normally the rabbeted piece is on the side to use the mechanical advantage of the joint. But then measuring the length of the front/back pieces also involves the joint. I wanted make this task as easy as possible so I used the full length, rabbeted pieces on the front & back.

I have a big bag of knock offs from Amazon and can confirm that they work well!

Looks great! How did you join the panels at the corners?

You should be wary of giving universal “bad idea” advice for under bench storage. I have a split top Rubou with a cabinet underneath that’s worked great for over ten years now. There’s enough room between the top of the cabinet and bottom of the bench top to let in a clamp head.

The diagonal brace is likely overkill and will get in the way of accessing the underside or a shelf should you choose to put one in. The whole bench will likely slide along the floor before it racks should you push hard enough.

Just writing so that other bench builders make that consideration not to shit on your project.
