How to bend handrails for spiral staircase
Spiral staircases are a great addition to your home, adding elegance and style to it.
Tauring machine
The easiest way to bend a handrail for a spiral staircase is to use a computerized tauring machine. For stair handrails you should choose a box section, like a semi-circular profile.
Setting up the machine
The machine uses a series of drive rollers that are set out to achieve a degree of bend required. The metal pipe is pulled through these rollers and then made into an arc.
Wood handrails
If you want wood handrails for a spiral staircase, then you can carve the wood or even bend it.
The carving can be achieved using a spoke shave. Use a compass to mark the circumference. Cut the radius using a coping saw and use a spoke shave to finish it. Now the depth can be scribed using the same tools.
You can bend the wood, just like the metal, using a steam bath and pressure. But be careful when doing this as the temperatures can be quite high.
