Tongue and Groove Joinery

After all tongues have been cut to match the grooves, dry fit your entire layout of all of your boards with the completed tongue and groove joints just to check and see how all of the joints will look when the boards are clamped together. This is the final visual check before assembly, so this is the time to correct any errors or address joints that are too tight.

NOTE: You may now remove your stacked dado blade set from your table saw, and install a clean, sharp all-purpose saw blade for use in an upcoming step.
