Cutting a stair stringer - GIF

[mwmkravchenko]

Carpentry is rapidly becoming a lost art.

I have made many sets of stairs open stringers and closed stringers. How to count what has been done wrong.

Screws do not make up for sound structural thinking.

And I agree with Hemmjo and Wildwilly. What a terrible job.

Now in regards to internal stringers I use plywood now. Laminate up some double 3/4" spruce and you are golden. Lay it up as long as you want to. Getting quality dimensional lumber like when I was a kid is not exactly cheap or readily available. If I can find 1mm lamination Poplar that works very well to.
