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.
- Engraving and ring holes, then cut out the gauges. For the small set use the 1.5 mm end mill and mill slowly so the concave radii stay accurate.
- Free the parts at the holding tabs with a utility knife or fine saw and sand the tab remains flush.
- Only deburr the edges, do not sand them, otherwise the radii are no longer correct.
Assembly and final touches
- Hold a gauge against the edge and look against the light: if the radius fits, no gap is visible. Thread the gauges onto a key ring.
