https://www.homebuildingandrepairs.com/old_homes/index.html - In this video, we are digging deep into the lost art of traditional carpentry, covering four distinct building methods, framing shortcuts, and formulas used by old-school builders.
What We Cover in This Video:
Roof Pitch Calculations (Correction): Fixing a mistake from my last video! We break down old-school fractional roof pitches (1/4 pitch, 1/2 pitch, 2/3 pitch) and how to easily calculate ridge height based on the total building span.
Pre-Plywood Structural Arches: How antique "mechanics" (master carpenters) framed arches in load-bearing walls using multi-piece layouts or by carving solid timber with a rigging axe.
Floor Joist Sizing Rule of Thumb: Testing an old framing formula (Half the Span + 2) against the modern 2021 IRC span charts to see if it actually holds up for Douglas Fir and Southern Pine.
The Gambrel Roof Circle Method: A brilliant, software-free trick to layout a perfectly symmetrical gambrel roof by snapping chalk lines directly onto your concrete foundation.
Whether you're restoring a historic home, checking your framing math, or just appreciate old-school craftsmanship, these rules of thumb are essential tools for your carpentry toolkit.
