Maya spent the day at the Road House repairing her tiny house. It will never be as good as new, but it is starting to look respectable again. She also delivered some 3D-printed prototypes I designed to anchor the stair railing balusters. A long screw is used to secure these columns to the stair tread and the hollow steel baluster is slid down over it. The ribs are necessary because the tubes are not perfectly circular and are not uniformly consistent in size. Unfortunately, a quick test revealed that this attachment method will not provide the degree of lateral support I was hoping for. I may still use this approach but will have to design a more substantial Newell post to provide the needed strength for the assembly.
