Carving and finishing
- Clamp the workpiece flat on the spoilboard or secure it with double-sided tape, and set the origin as shown in the carving assistant.
- Clear the recesses of the tray 2.5 mm deep, engrave the fractions, then cut out the tray and the circle pieces.
- Free the parts at the holding tabs with a utility knife or fine saw and sand the tab remains flush.
- Lightly break the edges with sandpaper (grit 120, then 240) and remove burrs.
Assembly and final touches
- Paint each circle in its own colour; then you see at once that two quarters are as big as one half.
- Ideas: Which pieces make a whole together? How many eighths fit into a third? The recesses show whether it adds up exactly.
