Arch Motors, based near Huntingdon, are responsible for making the Caterham chassis, and have been doing so for over 20 years. In fact, they make just about anything that is metal in a Caterham 7. The only thing they don't make are things like the seats, GRP wings and nose, engine, exhaust system, differential, wiring looms and weather gear!

Arch Motor & Manufacturing Company Limited was founded in 1958 by two successful motorcycle and sidecar racers, Bob Robinson and Ted Young.

Their first premises in Tottenham, North London was situated under railway "arches" hence the name "ARCH". Grants, and the need for more space, encouraged a move to Huntingdon, Cambridgeshire in 1966/1967. As well as maufacturing the Caterham, they have also been involved with Brabham (MRD), Chevron, Ford Competitions, Lola, March, Light Car Company - The Rocket McLaren Cars, Van Diemen, Ariel Motor Company - they make the chassis for the aerial Atom

The company is now run by Bob's son Bruce, assisted by various brothers! I have had the pleasure of visiting Arch on a number of occasions, and the photos that follow show the factory. As you can see, Arch weld together the chassis, powder coat, and then panel them with the aluminium skins.

They also produce all the suspension components; wishbones, de dion tubes and radius arms, and until recently made all the roll bars and cages.
