Spiral Stair in Timber Frame Cabin

May 2, 2013

Helen, Shannon and I (Josh) headed down to Bradford, NH last week to add a spiral stair and railings to a cabin that THLLC built last summer.  After a few weeks of preparation in the shop, three whirlwind days were sufficient to build winder stairs up from the basement, install the main spiral, put in a partition wall on the second floor where one of our railings terminates and install a curved railing on the first floor to protect the basement opening.

The stair features cherry risers, ash treads, cherry ballusters and ash railing strips (the spiral called for 18′ long continuous 1/4″ by 2″ strips, thanks to our terrific sawyer Mike Gendron!) all circling a central pine 8×8 with a liberal application of stainless trim screws and copper washers.
