Been trying to search online for some stair design guidelines.
I've found this great one here: gdwoodworking [dot] co [dot] uk/assets/files/bwf_stair_design_guide_2013 [dot] pdf
However I'm specifically looking for the amount of material needed under the top newel post mortice to support the stringer tenon.
I also need some help on the thickness of material needed after cutting the stringer to support the step.
Both questions are shown on the drawing.
Thanks for advice in advance.
