Peter, it doesn't have to be a fruit box, I'm sure Ian's is solid in layers. The denon plinths are usually hollow with just the top to sit the turntable in. I made thin ply templates to mark out the ply layers of mine. I only needed two different cut outs. You can have layers cut out and glued together in a rectangle with a cut out for a removeable arm board.
