How to build a set of stair stringers. Stair stringers are the structural backbone of a staircase. They’re the angled boards that support the treads (steps) and risers, transferring weight safely down to the floor. In this video, I’m showing how to measure, mark, and cut stair stringers accurately so your stairs are strong, level, and code-ready. #remodel #construction #contractor #diy #carpenter | Cody Romer

Stair Stringer Calculations. Part 2 of 2. Hopefully this explains the math and the thinking behind it. Dropping the stringer by removing the thickness of one tread from the bottom of the stringer is a common issue with new carpenters and DIY folks. Good luck with your stair building. 👍 | Justin Metzler
