Stairs That Flair Out As They Go Down
I am trying to figure out how to build some deck stairs that grow wider as they go down. Some call them wrap around stairs or cascading stairs.
They will have three stringers, one in the middle perpendicular to the deck and one on either side of it that would be at 45 degree angles.
I was trying to keep the steps parallel to the deck. The only way I can think to do this is to cut the riser part of the stringer at an angle that matches how the surface boards pass over them. The problem I see with this is that the stringer would be weakened too much on the inside edge and would probably fail.
