How we find the seat cut on CleanStairs stringers. 📐
Set the square on the second-to-last layout mark (the last mark is the plumb cut at the very bottom). Burn 4-1/2" straight up off the square, then mark the rise for that stair set. That's your seat cut, done the same way every time.
No guessing at the bottom of the stringer, and no stair that rocks on the pad.
📤 Send this to the guy who always fights the bottom cut.
