# Ancient Web: Dave Bayer Turned a Pasta Cutter Into a Woodworking Engineering Proof Mathematician Dave Bayer's 2003–04 pasta chitarra page joins Italian noodle-making, photographs, music wire, woodworking geometry, and calculations of frame sag. 2026-09-25 :: Switchboard Tech Services ![Ancient Web: Dave Bayer Turned a Pasta Cutter Into a Woodworking Engineering Proof](https://switchboardtechservices.com/static/images/defaults/articles.webp) Part of the [Ancient Web Collection](https://switchboardtechservices.com/articles/ancient-web-collection/). A pasta cutter called a *chitarra* looks like a miniature stringed instrument. Mathematician Dave Bayer wondered why making one should not involve a little engineering. [Visit Making a Pasta Guitar](https://www.math.columbia.edu/~bayer/Chitarra/). The page, copyright-dated 2003–04, belongs to Bayer's Columbia University web space. It begins with a cook's frustration over hand-cranked pasta machines, then becomes an elaborate study of Italian-style wire-frame cutters. A chitarra uses parallel wires to cut a rolled sheet of dough into strands when a rolling pin presses the sheet down. Bayer prefers hand-rolled dough and argues that the wire tool is easier to control than a lamination machine. His culinary preferences are personal, but his explanations of the device are carefully documented. ## The strings have to survive their own tension The [construction section](https://www.math.columbia.edu/~bayer/Chitarra/) deals with zither pins, music wire, drilled holes, brass guides, tuning keys, and ways to avoid kinking wire when threading it through a wooden frame. It includes photographs and dimensioned sketches of a real build. The text compares the stiffness of woods such as maple and cherry, examines how changing a board's thickness affects bending, and turns a simple kitchen tool into a statics problem. Bayer calculates that an eight-inch cutting area with 64 wires under twenty pounds of tension apiece resembles a bookshelf carrying 1,280 pounds. The example explains why a bigger chitarra demands more than a proportionally wider frame. There are kitchen notes too: let dough rest, understand why fresh-milled bran affects texture, and consider the shape of shorter noodles. Some sections openly identify themselves as unfinished notes. That admission is a useful reminder that personal project sites often published thought in progress rather than waiting for a polished book. What survives is a hybrid of recipe, toolmaking memoir, mechanical design notes, and annotated photograph album. A publisher might have insisted Bayer choose only one audience. His homepage lets all the audiences meet. Readers considering a build should account for sharp wires, tools, and modern food-safe material requirements rather than assuming every old suggestion is universally appropriate.
