What is the best way to reduce depth of this wooden box using hand tools only (I don't have any woodworking facility, like electric tools)?
I would like to remove the area outlined in red. The box is a wine bottle container.
Is it more practical to take the nails out and cut each side separately or cut through the box in one piece?
The tools I have, for this purpose, are a hand saw, hacksaw, hammer and chisel. I would be willing to purchase other tools within reason.
I want to use the item to cover a grate to stop noise coming through from outside. It currently can be positioned over the grate as the grate sticks out a bit.
