Sawing: With no problems other than its
hardness. Rapid blunting.
Drying: Slow. Slight risk of warping and cracks.
Planing: difficult because of its hardness and
risk of repelling. It is recommended that you
plane very slowly.
Gluing: the tannins make adherence difficult.
Hammering and screwing: because of its
hardness, it is advisable that you make drill
holes first.
Finish: the rubber sediments could inhibit the
adherence of varnish.
