https://www.homebuildingandrepairs.com/stairs/index.html - Whether you are dealing with funky riser calculations or ensuring the structural integrity of your stringers, this video packs in advanced carpentry techniques and practical framing solutions to save you time and materials on the job site.
Precision is everything in structural carpentry. Just as we rely on strict engineering ratios for floor framing and cantilevers, getting your stair geometry right the first time is critical for a safe, code-compliant build. In this video, we cover everything from the math behind odd-shaped stairs to the structural reasons why 2x12s outperform 2x10s on longer runs.
What's covered in this video:
Calculating Riser Heights for Odd Stairs: A breakdown of how to find individual riser heights for irregular stairs using math, story poles, and imaginary riser ladders.
Modifying & Reusing Short Stringers: Don't throw away that lumber just yet. Learn how to safely add material and create templates to salvage stringers that were cut too short, without compromising the stairway.
Avoiding Knots & Lumber Imperfections: A guide to strategically laying out your stringer patterns on lumber to keep knots and cracks out of your vital structural bearing points.
The Bent Framing Square Effect: A visual demonstration of how a slightly bent framing square completely throws off your tread, riser, and plumb layouts over the course of a stringer.
Installing Precast Concrete Treads: A comparison of attaching concrete treads to wood or metal stringers using welded plates versus bolted brackets, and why welding is often the superior choice for adjustability.
Professional Stair Building Secrets: A quick look inside the updated 2020 edition of my book, highlighting advanced techniques like undercuts, sloped exterior treads, and squeak prevention.
2x10 vs. 2x12 Stair Stringers: A structural breakdown of why 2x10 lumber shouldn't be used for long stairways, and how the meat left on a 2x12 or 2x14 after notching prevents catastrophic failure.
Forming Concrete Stairs with Wood Stringers: An efficient, unconventional method for using pre-cut wood stair stringers as the actual forms and guides for pouring concrete steps.
