I have a staircase that I need to install and was hoping someone would confirm that the installation method I have been advised to use is suitable.
The trimmer that attaches to the top riser needs to run at right angles to the other floor joists. I have been advised that I need to provide a cantilever double joist. To construct this cantilever I am told that I should cut out sections that are the width of the double joist and half the height. Then I should do the same on the cantilever joist and 'slot' the 2 together. (Crosshalving joint?)
Does this sound familiar?
Is this the normal procedure?
Can anybody offer alternative suggestions?
I am worried that the joint will not be strong enough as I am having to cut half way down the floor joists.
