Construction

Slotted and Drilled Strips

Cut the beech pieces to size. For the slotted strips, use a table saw or router to create grooves that will hold the knives. Drill holes for the pivot rods. Accuracy here ensures smooth fanning action.

A sturdy desk or work surface makes this step easier. If you’re setting up a dedicated workshop, check out sheds for storage or garden supplies for outdoor projects.

Building the Base Semicircles and Rods

Glue the two semicircles together to form the base. Insert the pivot rods (Ø 10 mm) through the drilled strips and secure them into the base. The Ø 30 mm rod acts as the central axis. Assemble all strips, alternating sizes as per the plan, and glue the top semicircle in place.

For a polished look, finish with food-safe oil. Display your block on a dining table or sofa side table. Add lighting to highlight your work, or coordinate with wall decor for a cohesive kitchen design.
