I only furnished the curved handrail for this job but that was (as always) a bit of a challenge. The rail had to make an ascending, geometric turn through 180 degrees, with pitch-changing transitions between the curved and straight flights.
The walnut rail was cut and shaped from flat, solid planks with no bending or strip laminating required. No forms or jigs were necessary. The cutting patterns were developed from the floor plan only, using tangent handrail, geometry from the 1800’s. The fit and installation was by others, 2000 miles away. (I never see the jobs but rely solely on the submitted plans.)
I do it this way because it’s easier than re-sawing, bending and twisting wood and in some cases, the only practical approach. No CNC machinery were employed either although that would be the modern method of today.
The custom volute is from another job It’s made to precisely fit the pitch of the rail with no up-easing. A volute like this, appears as a continuation of the curved or straight handrail, rather than a typical flat fitting, abutted to it. The volute layout is also geometrically correct, as it converges to a proper point.
I’ve been doing this for many years and on occasion, teach and lecture on the subject: “Tangent Handrail”.
