The steel inside

Posted on 2 May 2017

Overkill is our strong suite, but in the case of the newel posts on an outside stair, I think our approach is pretty justifiable.  The connection between the post and the stair stringer is often the first point of failure on a deck.  Typically a 4×4 gets bolted (or, mercy!, nailed) to the side of the stair stringer, and as people pull on the post going up or down the stair, the short grain of the stringer starts to fail and the post gets wobbly.

 

We’ve developed a system where we fabricate a steel sub-post on a thick plate, and then we bolt the plate to the concrete pad at the bottom of the stair.  The finished newel box gets installed over the steel with big-assed tek screws.  On a recent job, the geometry of the steel post was a little more complicated because we were using 3½” thick engineered beams for the outside stringers, but the general idea is the same.  We also had intermediate newel posts on this stair because of the long run.

Work of double curvature, or how to bend handrail the way it doesn’t go.

Posted on 12 May 2011

Mary Horst, of Horst Buchanan Architects, Inc., approached me in November of 2010 about reworking a stair in an early ’80s condominium in Jamaica Plain, MA.  The original stair was open, giving the new homeowners visions of late-night tumbles, and the design had not aged well.   Budget and logistics required that the framework of the stair remain, but Mary wanted to add risers and half walls, and eliminate the oak balustrade.  The biggest challenge of the job would be fabricating a new wall-mounted handrail. Mary’s new design required a continuous, smoothly curving handrail with no visible joints.  Because the stair transitioned from straight rise to curving rise and back again, the handrail would have to change pitch in addition to following the curve of…
