Bending stairs handrail.

[Skiddley]

We have an old house, original oak bannisters. The upstairs hall has a rail ~4m long that is bowed.

What is the approach to straighten it in situ? I don't realt want to take it apart as I'm concerned about damage that may be caused.

Clamp angle iron to both sides and leave? Some method involving steaming? Dampen the concave side before clamping perhaps?

It's bowing sideways. As if something has been leaning on it for years. I'll try and take a picture later.

 

[Skiddley]

yes, i think you're right.

Handrail is 98years old.
