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”.

Thanks

Looks good, .. excellent work, all just just using a hammer saw and tee square no doubt.

I see a couple of blank photo spots .. possibly a picture of the tool box and donkey would be nice.

Yeah funny Robert but no Loretto miracles here. There is some handwork involved but all of the cutting and shaping is done by machine. The handrail, including the drawing and pattern work, required no more than one week of my time. I’m a professional, not a purist.

That is one super job!! Well done – excellent craftsmanship. I can’t even begin to get my brain much past choosing the wood to do that kind of work. But it is definitely eye candy.

I had to look up “traditional tangent geometry”, and your “ThisIsCarpentry” article popped up on google. Fascinating topic. Your article has great illustrations that help clarify things. I am going to have to spend a lot more time studying your article. Thanks for sharing.

If that doesn’t make your head spin, nothing will ;-) Impressive work!

Inspiring to see the that level of precision, and purely from remote plans; very humbling.

Your work is impeccable. I had the pleasure of working with a very talented custom stair builder who would come in to the job, draw the plan out on the subfloor and build the most complex stairs I have ever seen field built. He did not make his own railing pieces. If I can find his card I will send your information to him

You’re petty damned good to do that without a CNC machine. I do this sort of stuff (in metal) but it’s all CNC. I’d never expect a machinist to do something like this free hand…but then, I use metal. That’s tough on the chisels.

Beautiful work!

Thanks all for the kudos and compliments. Not everyone can appreciate the amount of work involved here or the years required to gain the necessary skills. I believe most of you here get it though, as you’re on your own “long and winding road”.

thank you

This is amazing and the timing as well. I was just in Amsterdam for the weekend and stayed in a 350 year old house that had handrail up 4 flights of stairs that was just like what you have shown. To think that they did that rail without power tools. Every time I walked up or down the stairs I would run my hand along the rail and was amazed at the fact that all the curves, twists and transitions felt perfect. It was a work of art. I can attest to the fact that it was much more pleasing to the eye and very graceful. Even though I do not need any handrail I may make a curved piece just for the fun and education of it. Thank you for posting your work.
