Sawing in stringers

[Matteg01]

Hi

I am considering cutting away the stringers to widen the steps all the way out to the wall for a more streamlined appearance.
The question is how to best reinforce the stringers as the load-bearing capacity will be reduced.

I am thinking of gluing/screwing two finger-jointed studs 45*70.

Do you think it will work or will it start to creak?

Looks like it's a straight staircase?
I would think it's easier to build a new staircase using the old one as a template and execute it exactly as you want it.

The easiest is probably to prop up the walls so you can spackle against the vagnstyckena.

It doesn't sound like a good idea to cut into them, fill the gap instead?

45x70 sounds very weak. Something like 45x145 is more reasonable.

Cutting into the vangstycken (note the spelling) is not a good idea. The simplest solution is to reinforce the sides. The best solution is to build a new staircase. If the old one is unnecessarily narrow, you have additional arguments. In the existing staircase, space for treads and risers is routed into the vangstycken. A simpler method when building a staircase yourself is to screw and glue triangular supports for the treads and risers on the outside of the vangstycken. An alternative is to have underlying vangstycken, which can look nice if the sides of the stairway are attractive. Perhaps not relevant in this case. The vangstycken are dimensioned as beams, primarily taking into account the deflection (which should be minimal). Consider the span, the inclination, and that the load will be distributed on two vangstycken. A calculation example: If the staircase height is 2.4 m and the inclination is 45°, you can use 45x170 mm C 24 timber as vangstycken.

Thanks for all the tips! I'll be sanding and staining it for now, and I'll aim for a new staircase later.
