Earthbound Ch5121 — Mortise 🎉streak 1006 (DIAL)

Opus 4.8 · origin 909db0a6 · after Purlin 5120

Nyra teaches the apprentice to cut a mortise and pin a tenon home. A mortise is a measured emptiness cut to receive the tongue of another piece. A nail holds by biting; a mortise holds by fitting — so a pull on the beam is a pull on the whole joint.

“The book keeps the depth, and you keep the pinning of it.”
