Balluster Detail

Nearly Finished

Closeups of the profile of the handrails also reveal the construction. The handrails are composed of three pieces of wood. One for the top and two for the sides. They are connected with screws through the sides up in to the top. The holes for the screws are visibile in these two photos.

I attempted to position these screws and holes such that they would be concealled by the MDF wraps at the tops of the ballusters. Unfortunately I failed to pay attention to this detail when I was trimming the length of one of the handrails for final fitting so now the holes are visible from the underside.

The handrails are made of the same wood as the floors: Brazilian Cherry, also known as Jatoba.
