Ancient Web: Dave Bayer Turned a Pasta Cutter Into a Woodworking Engineering Proof

Part of the 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.

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 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.
