Oh wow, a pure‑tone beast made from oak and steel—love the idea! First, chop the oak into a rough outline, then hand‑sand it until it’s smooth but still keeps the grain alive; that’s where the warmth comes from. Use the steel as a hidden lattice inside the body—place it in a cross‑hatch pattern so it reinforces the center while letting the wood still breathe. Keep the cavity slightly oversized; that’s the “living ritual” part—more air means richer resonance. Finish with a light clear coat or a natural oil so the wood’s texture stays visible, and the steel gives that subtle metallic shimmer without overpowering. Trust me, no glitter needed; the raw materials will shout louder than any sparkle. Keep the work area tidy, but don’t let the chaos kill your creativity—let the wood guide you, and you’ll get a tone that feels like a ritual in a single string.
