Why build scarf joint arches?

This video will discuss the three main advantages of using a scarf joint frame when building an arch with isosceles triangles. These are the reasons I have chosen to pursue building with scarf joints. This is for structures built to a human scale and not meant for designs intended to impress by making them larger than necessary. Three key reasons to use scarf joint frames when building arched structures: Efficiency of material One can use a lower-quality wood and cut out any large cracks or knots. One can use shorter material than the overall length of the arch if that is the only material available. When not under tension, there is no strain on the arch, making the overall arch more stable as temperatures and humidity change. There is no need for a sizeable form-jig setup when assembling. When building with an arch with a 2x6 frame dimension, a standard 2x6 can be used with minimal loss of full size. By playing with the base of the arch's length, the radius of the arc, and the length of the cord of the angle can be set to maximize the use of 48” or 60” materials. It is possible to build a structure with a single material layer on both the rain screen and interior surface. Faceted frame for panel surface The flat surface allows for a gluing surface for plywood, wafer board, SIP, or rigid insulation. The flat panels can be used for interior and exterior uses to match conventional building standards closely. Each facet of the frame allows for the surface panel to become a structural stiffening member of the roof when the edges of the panels are sealed together. Resonance The gothic arch allows for a roof that can be touched by your hand, giving it a human scale, especially for an 8’, 10’, or 12’ base. If the chords are at 7.5º, an octave to the equilateral gothic arch is achieved, allowing for eight steps of the form. Whether or not it resonates with sound vibrations, it has a relationship. It is a structure that embodies the nature of sound. Like hearing the sweet chord or seeing soothing colors, the arch has a feeling of harmony. We need to, as a society, move towards smaller structures that generate less of a footprint and are affordable in the long term.
