Moravian style bench pics :

Google also turns up many variations.  I really like the tusk tenon build,
and Will Meyers shows how incredibly strong these are in one of his videos
(hydraulic tester).  Worth watching.
  The build is a bit more complex because of the angles, but then you are
rewarded with a rock solid bench. I'm going to build one to use on my bit
of land near Killarney Ontario (boat access only) .  I need something I can
breakdown to a compact size so it will fit into a tiny storage shed, not to
mention small enough to transport on a small fishing boat.
