Carving and finishing

  1. Clamp the workpiece flat on the spoilboard or secure it with double-sided tape, and set the origin as shown in the carving assistant.
  2. Engrave degrees and arcs, mill the ring holes, then cut out the gauges.
  3. Free the parts at the holding tabs with a utility knife or fine saw and sand the tab remains flush.
