My wife teaches language arts to 7th and 8th graders. She asked for a book cart which morphed into a tabletop book display, one for each of her four classes, so a student could curate a bunch of books each week.
Nice work! How does it transform into a book cart - sits on a trolley?
Also I’ve been doing similar work with ply etc and found a bolt style called demon bolts, also called Joint Connector Bolts. If you flipped the bolt around and machined a recess for the head it would give a flush and professional finish on the outside panel. Just a thought.
Love the hardware recommendation. I was just using what I had on hand due to impatience.
These don’t transform into a cart. I designed the cart and then decided to create a single shelf to test all the tolerances. She liked the shelf idea better so we evolved that design into what it is now.
