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.

I've been doing this for many years and on occasion, teach and lecture on the subject: "Tangent Handrail".

Hi Jim. This is an incredible skill you possess. I am humbled.

Regards, Ken.

Jim- Was this the rail you mentioned in a Woodweb post where the radius of the treads would not allow smooth rail transitions in plan?

If so, you pulled it out well. Very well. You made everyone else look good with your work.

Thanks for posting.

Dave, sounds like one of my tirades and certainly applies here as well.

It's not the radius but the position of the risers which forces the handrail easements.

I'm proud of this job as I believe it's the best anyone could do with this layout. A change however, from "balanced winders" to "dancing winders" would have eliminated the noticeable easements altogether.

Either way, the handrail for this stair should be considered way beyond the limits of any factory bender-rail (although I've seen it hashed out often enough.)

Very well done Jim,
I often wonder how that is accomplished. How do you shape a handrail like that with such drastic this done by hand- carving/scraping...shaping.....?

Very nice craftsmanship!


Posted By: Greg van Nurden     [09/30/2013]
That looks real good Jim. You have a lot to be proud of. The future of the stair industry looks a lot better with you involved the way you are.

Posted By: Jim Baldwin     [10/01/2013]
The cutting and squaring is done primarily by bandsaw but finished with spokeshave and rasp. The profile milling however, is all machine, of my own design. There was no handcarving required here.

I had Jim do a descending/twisted rail for me twenty years ago. It was gorgeous. by now he has had a lot more practice. and no he won't show you the shaper.

Posted By: Mark Slafkes     [10/02/2013]
I wish I could remember the math you've used here. Too long ago. Clearly, you are very smart and very skilled. Wonderful work.

Great looking job only done by a professional. -Bob

You are truly an artisan. How does one learn the geometry required to do this type of work in today's age of CNC?
Also, are any of your lectures online?

Posted By: Jim Baldwin     [10/06/2013]


There are now a few old books available on-line and in reprinted format. The most contemporary author is perhaps, George diChristina "A Simplified Guide to Custom Stairbuilding and Tangent" Handrailing

Here's a link to an article that may also serve as an introduction.

I can tell you however, that trying to grasp and learn this subject without some assistance, is very difficult (as there is nothing simple about it). I suggest findimg someone with practical experience to help. This may be easier said than done but it can litterely cut "years" off the learning curve.

I've just completed a four-day seminar in Martha's Vineyard, MA but may do this again next year.

Either way, I try to make myself available to help others as my schedule permits. Look me up online if you're interested.

Thanks (and thanks to all for the many kind words)

Beautiful job! I know exactly what goes into making a complex handrail like this. I design high end stairs for a stairbuilder and have to create 3D models of high-end elliptical and radial stairs. The geometry involved is very complex. I have worked out my own methods to create the geometry, which has to be spot on because the files are either sent to a cnc shop to cut the parts, or templates are printed off my drawings to cut the parts by hand. Very nice work!

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator
    (return to top).

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
