The Kazam! Machine

A Vitra Anecdote

In 1941 Charles and Ray Eames turned their LA apartment into a workshop. The Kazam! machine, a DIY-device for moulding plywood, was the key to the creation of the Plywood Group, chairs made from plywood shells with compound curves.

In their quest to find a way to mould plywood three-dimensionally in order to produce low-cost chairs – as well as sculptures, aircraft parts, leg splints and children’s furniture and toys – Charles and Ray Eames were relentless. During their first years in Los Angeles, in the beginning of the 1940s, the young design couple worked at home, where they set up an ad hoc workshop in the guest room. Before long, this workshop had expanded from the bedroom to the kitchen. Their greatest concern at the time was the development of the capacity to apply pressure to plywood without breaking it.

"Ala Kazam! – like magic."

After various failures, they eventually created a home-made apparatus for bending wood, a kind of curing oven made from wood scraps and spare bicycle parts. They called it the Kazam! machine. Made of a hinged and bolted curving plaster mould, the Kazam! machine allowed them to create a glued sandwich consisting of several layers of veneer, which was then pushed against the plaster mould by a membrane which, in its turn, was manually inflated by a bicycle pump. But the heated mould, with energy-hungry electrical coils running through it, required a lot more current than their home circuit could provide. So Charles climbed up a nearby power pole, carrying a large piece of heavy insulated cable, in order to poach enough electricity to run the Kazam! machine. Charles was afraid that he would electrocute himself. Luckily, he survived, and in the spring of 1945 the Eames succeeded in creating the Plywood Chair LCW (Lounge Chair Wood) made from plywood shells with compound curves. It was the beginning of the Plywood Group.

The Victoria & Albert Museum in London is currently hosting an exhibition that explores the history and production of plywood. Exhibits include prototypes by Charles and Ray Eames, Alvar Aalto and many other designers. More information
