How to get your groove back
The chamfered edges of the boards (D) create V-grooves that accent, rather than hide, the joint lines.
Chamfered edges on edge-joined boards create V-grooves that accent, rather than hide, the joint lines. But the grooves also collect glue squeeze-out. To remove it cleanly, let the adhesive set for about 20 minutes; then, gently shave it away. A bench chisel will work, but the blade of a crank-neck chisel rests flat against the panel, reducing the chances of digging into the boards.
