Lavoratti Cioccolato

We never put a client-supplied file straight onto a production part. The first test cut told us everything we needed to know: the artwork's overlapping strokes had no consistent width, so the cutter cleared them as broad open pockets instead of drawing lines. The spiral flattened into a run of blobs, the chambers merged as they wound toward the centre, and the shape lost the crispness that makes a nautilus a nautilus. Beautiful as a drawing. Unusable as a toolpath.

This close-up is the diagnosis. Where the original wanted lines, the router left channels — wide, soft-edged, and fuzzy at the shoulders, exactly the kind of surface that only looks worse once paint goes over it.

So we rebuilt the nautilus from scratch as clean single-width vectors, scaled the geometry to the door panel, and matched the line weight to a specific bit so every stroke would be cut once, at one consistent depth, with a sharp shoulder. Then we cut it again. And again, until the test part looked like the drawing.

With the file proven, the production run became the easy part — which is exactly how it should be. Doors came through in matched pairs, each one indexed so its spiral faced its partner, and nothing about the machine time was a surprise.

The mint door in front is the client's own finish sample, engraved so they could see how the cut would read once colour went over it. Behind it, a bare panel carries the same nautilus in raw material. Same file, mirrored. Same depth. Eighteen times.

Up close the payoff is obvious. The line holds an even width from the outer sweep all the way into the tightest chambers at the centre, the shoulders stay crisp enough to take paint without filling in, and the tail carries off the panel in one uninterrupted stroke.

Set two doors next to each other and the spirals turn toward one another. It is a detail nobody consciously notices and everybody feels.
