Create geometric wall art by plunging parallel grooves into hardwood or plywood panels, then easing the panel edges with the roundover. Vary spacing and depth to form rhythmic, mid-century style flutes and shadow lines.

Build a small box, round over the lid and base edges for comfort, then add shallow plunge grooves across the lid as a tactile pattern and beneath the box’s sides as subtle finger grips.

Fabricate a guitar pedalboard or display shelf and soften all exposed edges with the roundover. Add evenly spaced plunge grooves along the face for visual rhythm and cable-routing markers.
