This box is a evolution in my box design but it may not be obvious. I’ve always been conflicted about tops and bottoms. In order to keep from spending $50 on hardware for each box, I decided to use an overhanging lid to create a natural stop in the open position. An overhanging lid pretty much means I need to use an overhanging bottom too. A solid bottom can contract over time and so glueing the sides to the bottom doesn’t seem like a very good idea unless you screw it to the bottom so the glue doesn’t break later. That leads to a crack in the bottom unless you use slots for the screws because the bottom will still contract and expand. My solution is to use a sliding dovetail. The bottom is one solid piece that has been sawed in half parallel to the grain direction so two sliding dovetail slots on each half can be made. Then the long sides of the box are given a sliding dovetail male piece to fit into the bottom’s slots. The sides are then captured in the dovetail in the bottom but not glued in place. The bottom is then glued back together taking care not to glue down the male dovetail. The net result is a bottom free to expand and contract that matches the overhanging top and sides that aren’t glued or screwed in place. Woods are marble wood for the sides and mahogany for the top and bottom. By the way, that marble wood is very brittle and comes off the router in little slivers that get everywhere and won’t let go. Love the look though. Tung oil finish.
