Hello just looking for some info on how to construct stringers for my stairs. The fan or half octagon stairs or going on the front of my deck on a straight section, just not sure how to make the two angels or one angle work. Thanks

For a fan you take the stringers out on a radii.

For Octagon you frame the cantilever at the angles & take the stringers down from that.

You don't cut the stringers to make angles. You cut the risers to match the angles and place the treads over the top of the runs.

Use a stringer stock wide enough for the back-cut of the rise & run, you typically want a min. of 3 1/2" left, (this depends on a lot of variables- for a example a short total run). If you do cut deep like that add an additional 2X4 sistered to the stringer, and shorten their on center.

If you cut a stringer to make an angle as you suggest, you have to support it from below then start the stair again.

Refer to a structural engineer so you'll do this safely.

Thanks for your posts. It really helped me out. The 135 degrees of the Octagon then divide in half to get your decking angle of 67.5 degrees was all Greek to me. Here's my tip- rather than going out and buying a protractor and measuring each angle as you cut it, just set your chop box to 22.5!

Thanks again.
