Deodar Cedar and Walnut Strip Milling and Precision Channelling for Pinjrakari Screens

The extraordinary longevity of Kashmiri Pinjrakari rests entirely upon the discipline of the lumber mill. Because an individual lattice screen incorporates thousands of timber strips measuring less than three millimeters in thickness, any internal structural tension, grain runout, or residual moisture will cause the completed screen to warp, buckle, or fracture within a single change of season.

Master artisans begin by selecting mature, slow-growth Deodar Cedar (*Cedrus deodara*) logs felled from steep northern mountain ridges, where tight annual growth rings provide supreme dimensional stability. The timber is never kiln-dried with forced industrial heat, which crystallizes resins and leaves wood fibers brittle. Instead, boards undergo natural air seasoning in shaded racks along the Jhelum River for eighteen to twenty-four months, allowing wood moisture content to reach perfect equilibrium with the local Kashmiri atmosphere.

In historic workshops, raw logs were not sawn with heavy circular blades. Saws cut blindly through wood fibers, creating "grain runout" where tracheid tubes exit the edge of the strip, drastically reducing tensile strength. Whenever possible, craftsmen preferred riving—splitting straight-grained bolts of timber along natural cleavage lines using froes and wooden mallets.

Rived wood splits strictly parallel to continuous cellular fibers, guaranteeing that every strip possesses unbroken longitudinal grain from end to end. If modern sawmilling is employed, logs must be strictly quarter-sawn, with growth rings oriented between 80 and 90 degrees to the wide face of the board. This orientation ensures that any subsequent seasonal movement occurs entirely in the thickness of the strip rather than its width, preserving the microscopic tolerances required for interlocking joinery.

Achieving uniform thickness across hundreds of delicate wooden battens requires specialized hand tooling. The Pinjrasaz designs custom wooden shooting boards crafted from dense wild apple or hornbeam. These fixtures feature a recessed guide track calibrated to the exact target thickness—typically 2.8 millimeters.

The artisan rests a rough-sawn batten into the bed and drives a specialized wooden plane (randa) down the track. Fitted with a razor-honed Japanese laminated steel or antique Damascus steel iron, the plane shaves away gossamer-thin curls until the wooden sole rides on the hardened reference rails of the shooting board. Through this purely manual, tactile process, an experienced master dimensions hundreds of identical strips to tolerances within a fraction of a millimeter—a feat rivaling modern CNC machinery.

Once dimensioned, each strip undergoes secondary profiling. To provide mechanical registration and prevent light leaks where strips intersect, craftsmen plow a continuous micro-groove along one or both edges. This is executed using a traditional scratch-stock gauge (soz)—a hardwood block housing a shaped steel tooth that scores a clean, 1.2-millimeter-wide central channel along the flank of the strip.

Finally, the outer visible corners of the strip receive a micro-chamfer. While this step appears purely ornamental, it serves a critical environmental and perceptual function: in high-altitude Himalayan sunlight, square-edged wood strips cast harsh, dark shadows that create visual vibration. The chamfer softens the shadow transition, producing a gentle, luminous gradient across every geometric intersection and transforming harsh alpine sunlight into tranquil, diffuse illumination.
