To receive the bottom, the cabinet end panels are usually which?

• A. Notched
• B. Dadoed
• C. Rabbeted
• D. Routed

Answer: (D)

End panels are usually routed to receive the bottom panel. Cutting a shallow groove in the inner edge of the end pieces creates a channel that the bottom sits in, giving a clean seat and room for wood movement as humidity changes. The groove depth is just a bit less than the bottom thickness so the panel sits flush and can be glued or nailed in place as needed. Routing is preferred here because it provides a precise, unobtrusive catch that is easy to align during assembly, whereas notching would weaken the edge; a dado would cut across the end panel rather than along its edge; and a rabbet would require a larger shoulder, which is less common for this joint.
