Build instructions

Apart from the workpiece you need nothing else.

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 the labels, mill the grip hole, then cut out the spreaders with the 1.5 mm end mill; it fits into the gaps between the teeth.
  3. Free the parts at the holding tabs with a utility knife or fine saw and sand the tab remains flush.
  4. Only deburr the teeth, the edges should stay sharp.

Assembly and final touches

  1. Apply glue in a bead and pull the spreader over it at an angle in one go. Wipe it afterwards; dried residue can be flexed off the acrylic.
