Stair cladding and railing

We have now moved well into the finishing stage of our stair project that features an integral landing three piece open tread staircase.  The job of cladding and railing these stairs has proven to be more complex and time consuming than we initially suspected and our three initial carpenters weren't able to commit to the job to our satisfaction.  Fortunately we were able to locate a new stair builder and railing expert and he wasn't intimidated by the project.  Here are some initial shots of his work to date.  Note that he is cladding the middle stringer components in such a way as to portray the appearance that the stringers are solid, rather than veneered hardwood.  He also has cut some of the material in such a manner that it mimics the upper 'birds mouth' style of joinery between the stringer and floor structure.  We are using the type of hand rail called a 'd rail' profile.  It achieves the modern look we are after.
