💡 How do homebuilders lay out consistent stair stringers using basic aluminum framing squares?
The secret lies in mastering basic angle geometry and leveraging sturdy aluminum tools.
- Lock the moving pin against the board face to establish a fixed reference line for every subsequent step rise.
- Slide the angled bracket flush against adjacent joists to duplicate identical slope profiles across wider deck areas.
- Keep the ruler shoulder tight against timber edges to track exact angle geometry during heavy structural setup.
