Testing the Back Joint and Geometry

Last night I made a simulation of the back support bottom mortise and tenon joint so I could test it.  This morning I loaded it.  Seems adequate :-)

Today, I made the connection for the back rest cross bar and test assembled the seat and backrest for a trial sit.  It felt very good, but I decided to trim the mating surface of the back support bottom joint, to raise the angle to be slightly more upright, about half an inch forward, which required just an eighth of an inch trim at the joint.  This is done now, including tweaking the pre-tensioning lag bolt at this support's weak spot.  Nothing left but to install the Zebra wood parts and apply final finish.
