DIY Weekend: Mutant four-wheeler for road, rail
New Crave series kicks off with the Hennepin Crawler, a quirky, functional four-wheel contraption made from 90 percent found parts.
Krank-Boom-Clank, a three-person kinetic industrial arts collective in Santa Rosa, Calif., spent one night a week for six months building the quirky contraption, one of their "mutant ride-able sculptures of delight (aka 'freak bikes').", a new Crave series spotlighting readers' do-it-yourself creations, kicks off with the Hennepin Crawler. Members of
Built for four riders, the Crawler can handle both street and limited railroad-track cruising at The Great Handcar Regatta (and, of course, the playa at the annual Burning Man countercultural arts festival).
The creators of the Crawler (Clifford Hill, Skye Barnett, David Farish, and former Krank-Boom-Clank member Dan Kirby) built the Hennepin improv-style from about 90 percent found parts, including discarded lawn furniture; truck, antique Cadillac, and VW Bug parts; an old dune buggy seat; spools of aviation wire; old bike bits (handlebars, cranks, pedals, sprockets, and chains); and an antique doorknob. It rolls on 4-foot diameter culvert pipe with some 900 parts per wheel.
The team scavenged most of their components with the Hennepin Crawler in mind, but others were "waiting patiently in our studio to be incorporated serendipity-style," Hill says.
Though the creators originally envisioned a box frame for their art car, plans changed when they chanced on a discarded free-standing yard hammock frame. Its sectional multitube crescent design was reassembled into curving dragon-spine lines that the Krank-Boomers found to be lightweight, flexible, strong, and easy on the eyes.
The Crawler, they say, "represents a melding of alternative transportation innovation, human-powered kinetic sculpture, recycling functional garbage, and a prankster's notion of inflicting bewildering beauty upon an unsuspecting public." For those who want to lend a whimsical, Jules Verne feel to a party or event, Krank-Boom-Clank even rents out the Hennepin Crawler. But at $4,700 (plus a fee for handlers), it will cost you more than a clown.
