Here are some pictures of a custom handrail we did in a vacation home in Summit County.
The newel posts are solid white oak.
The balusters are poplar, painted white. Their rectangular shape maks for a great look.
We had to notch the top cap of each newel post to accept the handrail. It was very delicate work.
Here are some close-ups of some of the 'fittings' (the parts of the handrail that are bent).
They create a great transition between levels of the staircase.
