A small commission for £

Postby thatsnotafestool » Fri Jan 04, 2019 2:51 pm

Would anyone like to make a curved banister, something like in the photo, for us ?

A couple of years ago I watched a you-tuber set out and make a "ramped and wreathed" handrail and it was amazing and very technical but I would guess its a job for a CNC guy today . A friend of mine has done them but he's on the verge of retiring so probably not interested.. I'd love to try and make a spiral staircase but its not gonna happen unless I buy a lace that needs one . Wouldn't entertain charging people for one unless I'd made one previously..

Good luck I'm sure there is someone out there..

I guess it's a neat opportunity to do this on your house and get some practice, but you gotta have at least a good idea on how to do this. I surely don't. haha

Hi Roger,

Is it at all possible for you to look at doing this yourself?

I have done a lot of reading into this type of work but unfortunately not attempted it (full scale) as yet.

It is possible to buy a volute (Very Bottom curved handrail part) from pre made machined stock (shelf items). I'm not sure if you would have the time to do the wreathed handrail but there is a good introduction video on utube

https://youtu.be/CyhVPMUahCc
that gives an interesting technique to make one. The technique is simple to understand so worth a look.

Traditionally these handrails could be made using solid sections of wood. One system is called the tangent system and it is based on circles and ellipses. A simplified explanation is:
1. obtain the rise of the handrail around the curve
2. cut a block of wood and temporally glue (glue gun) a wedge equal to the rise under it.
3. Use a bandsaw to cut the handrail section from the block
4. Mould the handrail

You need to draw the cutting lines on paper first and stick the paper on the block so you have some lines to cut to while using the bandsaw.

The lines can be drawn on the paper using the tangent system, so you really need to read about a little about the tangent system to understand how it works. The drawing will work out on paper to be an ellipse but when placed on top of the wood and lifted by the wedge (to give the rise of the stair) it will actually form part of the wreathed handrail (A 1/4 circle to be cut on the bandsaw). The 1/4 circle forms one part of the curve on the wreathed handrail and can be initially cut on a bandsaw before final shaping.

It's not beyond any one of us to do this type of work but it is very time consuming.

You could also build a former out of wood and use that to bend laminated strips along a pitch line to form the handrail wreath.

If I lived closer I would definitely consider working on this with you.

Is there any update on how this is going Roger?

Not much till the handrails really but we normally do all by hand and no CNC involved

I don't think I have actually seen a CNC machining a large curved handrail section yet, Volute and such like yes but all the large curved sections have been done by hand that I have seen so far.

It would be interesting to see your technique for making them if you don't mind sharing?

Well, well, well. LOML was very much on my case to outsource this given all the other stuff I've got to do and much as I'd liked to have had a crack, I could see her point. So I recently contacted a local firm who looked the bees knees. Bottom line - they see it as a lot of work onsite especially as it's adapting something that is already there - and they're not geared up for that length of time onsite. Had a good talk with the guy and I could see his point.

Reported back to LOML who said 'Well, perhaps it's for the best. It would cost a lot. Why don't we do it ourselves'. :o

Summat else to put on the TUIT list.

I think this might be your most testing project to date Roger, and I will look forward to hearing about how you tackle it. I don't think this the type of work what most joinery companies would be comfortable in doing (even very good ones) as it's a specialised area which is not commonly understood.

Do keep us updated Roger.
