I'm ready to make trays to go into cedar chests. They are similar to a drawer and will be 1/2" dovetailed on all 4 corners. The trays will be 3" in height x approx. 17" square. The drawer bottoms will be made up of 1/2" thick edge-glued stock.

My question is what sort of detail is required to make the dados into which I can slide in the bottoms to the sides? Stopped dadoes at the fronts?

Thanks,

Bryan
