Traditional Newari Craft Meets Modern G-Code (digitizing motifs, carving precision lattice/jhyal)

The most surprising thing about a CNC machine in Nepal is where it fits: right beside a craft that is six hundred years old. This episode shows how a Newari motif becomes G-code without losing the craft.

Start by digitizing the motif. Photograph or measure the original carefully, bring it into a vector editor, and trace the lines that matter. For a repeating lattice or jhyal panel, you only need to build one unit of the pattern. The machine repeats it for you, perfectly, as many times as the panel needs.

Keep the geometry honest. A jhyal lattice is built from interlocking lines that must meet cleanly, because any gap shows up as an ugly shadow in the finished wood. Work in two and a half dimensions mostly - flat relief cut to a chosen depth - and only reach for full three-D carving when the motif truly needs the depth.

Then choose the toolpath for the job. A strategy that cuts the open space between the lattice lines first, then steps down in small depths, keeps the thin carved members strong. Small step-downs and a sharp bit are the difference between a crisp peacock panel and a torn one.

Here is the part we love: the machine does the repeatable work, and a hand finishes the rest. After the router cuts, a carver takes it the last few percent - the final bevel, the smoothing no machine matches. That is the whole point of this venture.

The heritage value is real. A restoration that needs one exact replacement panel, or a hotel that wants forty matching ones, is a job the hand alone cannot do in time and the machine alone cannot do with soul. Together, they do both.
