Race cars made in NZ

Craig Greenwood is one of the best examples of someone who turned his passion into a business. He is also one of New Zealand’s most prolific racing car builders. Craig got into motor racing in the early 1990s, progressing from competitive cart racing to Formula Vee (now Formula First). The class is based on a 1200 cc VW motor and uses a collection of stock parts to form a competitive car from the engine, transmission, front suspension, brakes and wheels built into a space frame. The body is fibreglass or carbon fibre. It’s a racing class that allows an enthusiast to build and maintain his own car. Craig bought his first car but soon decided to build his own, working nights and weekends in a cramped single garage with little more than an oxy-acetylene welder, a hacksaw and a hand-held drill. “I wasn’t all that successful at first. Of 18 starts I made, I only finished four,” says Craig. “I realised that just knowing how to weld a chassis wasn’t enough, so I started to read about designing and building race cars.”

Craig bought his first car but soon decided to build his own, working nights and weekends in a cramped single garage with little more than an oxy-acetylene welder, a hacksaw and a hand-held drill.
“I wasn’t all that successful at first. Of 18 starts I made, I only finished four,” says Craig.
“I realised that just knowing how to weld a chassis wasn’t enough, so I started to read about designing and building race cars.”

The cars are driven via chain drive. This is similar to the locked diff common on race cars but allows for a very efficient transfer of power and less weight

Competitive
The cars got better, and he started becoming competitive. He realised it was more productive to build multiple cars and race them as a team. By 1993, with three cars, Greenwood started a scholarship system to find other drivers for his team. He was by now becoming competitive in the class. Before long, he had a team of six and was one of the biggest racing teams in the competition.
Craig went on to win the New Zealand Formula Vee Championship in 1997, and his team won in 1998 and 1999. Craig has built 23 Formula Firsts and developed a reputation for building quick and reliable cars, most of which are still racing.
By 1999, Craig had come up with a new design. Based on the Formula First series and with the knowledge earned from running his own team, he knew the drawbacks in the current design.

Motorcycle engine
“I realised I could build a car from a space frame and a motorcycle engine. I wanted to make it simple. The car needed to have easy access to replace or work on the motor, it needed to have easily replaceable parts, and above all, it needed to look and sound like a racing car. So we designed the body to look like a ’99 Ferrari.”
Craig wanted to go beyond simply owning the team, he started a new series—Formula Challenge. With that, he also pioneered the “arrive-and-drive” concept, where drivers could lease cars or simply rent the car for the race. All the cars were set up to be identical; the only variable should be the skill of the driver. This was intended to be a driver’s championship. He also ran a scholarship program to encourage new talent.
By 2002, the series had won recognition on TV with a winter series. The series ran to 2005.
Formula Challenge Racing now concentrates on providing individuals with the thrill of piloting a car that looks, sounds and handles like the real thing. It has a base at Taupo raceway but is also available at Hampton Downs and now at Rua Puna. They run 12 open-wheeler Formula Challenge cars and nine Vs, both Ford and Holden, to cater to all tastes.
The Challenge car has changed little; the power plant is a Suzuki GSXR 1100 cc motorcycle engine. The car sports wings, spoilers and a demountable nose section which has a safety element. In any impact, the nose section helps to absorb damage without distorting the chassis or suspension.
The suspension is hard in typical race-car style, and the steering is positive and responsive. The sequential five-speed gearbox is controlled with two buttons on a demountable steering wheel.
The car generates an impressive 150 brake horsepower with a top speed of 230 km/h. It is capable of 0-100 km/h in 3.8 secs. It can generate a force of nearly 2Gs on corners, and at a maximum of only 40 mm off the ground, the driver has a sense that the speed is electrifying.
Before heading off for a few laps, drivers see a video of a track drive. The cars are linked to a datalogger so the team can analyse each lap with the drivers to highlight good and bad practices to help drivers fine tune their skills.

Creative duet

12 August 2026

For Dave Pauling, making guitars is the natural fusion of two passions – music and wood.
Dave, who has been playing the guitar since he was 13, also knew the pleasure of pottering in sheds from a young age. His father is a “sheddie” from way back who, among other things, still spends many hours restoring vintage vehicles.
“I grew up helping him with his Model Ts, making bows and arrows, or working on a model railway we had in the loft,” he says.
While Dave himself has spent a fair few hours restoring a 1965 Mustang imported from San Francisco, he prefers working with wood. There’s something about the malleability and smell of wood, as well as its provenance, he says. Wood, especially the recycled timber he uses to construct his guitars, has had a previous life. “Every guitar I make comes with a pre-history.”

Rust, me and CRC Evapo-Rust

11 August 2026

My tools and machinery were housed in an unlined shed for a few years, resulting in plenty of surface rust.
I tried removing it with abrasive products, but that involves an awful lot of manual labour and doesn’t always work well, not to mention the scratches it leaves on the tool’s surface. So I looked for a decent rust killer. CRC Evapo-Rust had a reputation, so I gave it a go.
Most of my affected tools were small enough to be immersed in the liquid. I had a container that I filled with Evapo-Rust, and an overnight immersion generally cleaned them up. The beauty of Evapo-Rust is that it’s reusable, so that container will last for the foreseeable future, probably a year for me.

A butterfly takes wing

6 August 2026

This simple butterfly pendant or brooch (depending on the back fittings) is a very good exercise in several basic goldsmithing techniques. It also can be decorated in several different ways to produce strikingly different finished pieces of jewellery.
I drew this design more than 25 years ago for a company that then made paua-shell jewellery. They stamped out their products, so I often made the master patterns in copper and from these patterns they spark-eroded the dies.
If this design was being made in an art school, it would be stuck to a sheet of silver and the basic shapes cut from there. If a design was made this way in, say, 18-carat gold and the wing outlines (as here) made from 2.5 mm thick metal, the outlay and waste material would be considerable from a 2.5 mm-thick sheet of 18-carat gold plate. But we will make it like a professional craftsman who has to live in the real world where costs matter.
