I’m interested in Nakashima’s use of the cantilever principle in his Conoid chairs.  Does anyone know specifically what kind of joint he uses?  The joint in the chair’s sled-like base is pretty straightforward, though I’d love to know what angles are possible for the legs.  And the critical joint of the seat is most interesting.  What kind of joint is it?  How does one know how much weight can be borne by the joint? 

Does anyone have any drawings of the joinery?  I don’t recall seeing diagrams in Nakashima’s book.

Thanks!
