Easy listening: 1970 McLaren F5000 M10B start up

19 July, 2017

Bruce McLaren knew a thing or two about hill climbing and the first event the then 15-year- old Bruce ever competed in was a hill climb. Bruce won his class on the shingle slope, and his destiny was set.

Fast forward to the mid 1960s, and a short run of cars built specially for hill climbing and sprints. David Good purchased one of those hill climb specials — McLaren’s new M10B — which was essentially the same as the 1969 title-winning M10A, but with the key tweaks being redesigned suspension, a slightly restyled body, a new radiator, and modification to accept a dry sump engine installation. Good never let having no right arm dissuade from getting involved in sporting activities, either, however, he was never able to get a licence to race cars — the next best thing then was to head for the hills. Good had his McLaren fitted with a 5.5-litre Chev pumping out some 335kW at 6000rpm. The cockpit was modified because its pilot needed to sit close to the wheel — and, uniquely, the car had a much- modified gear linkage so that Good could change gear. The hole for the shaft on the left-hand side of car (the McLaren, like most racing cars, being a right-hand change) remains. Good was fourth in the championship after one ‘fastest time of the day’ (FTD), a second and a pair of thirds.

Today the car resides in New Zealand, owned by David and Katya Mitchell. The Mitchells had it shipped to New Zealand in May 2014, and it appeared at the Gulf Oil Howden Ganley Festival at Hampton Downs in January 2015. David will compete in Formula Libre races in the coming season, and intends to retain the treaded tyres rather than make a move to slicks.

The next issue of NZ Classic Car will include a full feature on the 1970 McLaren F5000 M10B, but for now, enjoy the beautiful sound of this historical piece of machinery firing into life in its makers own workshop 57 years later:

Coaching from the bench: Casting plastic knobs and rubber parts

16 July, 2026

Casting rubber items is simple if you have a good original to work with. The item doesn’t have to be perfect. You can use plasticine to smooth out cracks, and you can even make whole prototypes out of low-fire modelling clay available from craft stores if you need to. Prototypes can also be made of wood or metal.
You will need mould dams to contain the liquid urethane moulding solution until it cures. You can build boxes out of strips of wood, but I have found that small plastic boxes and bowls such as those you would use for leftovers in your fridge work well if you spray them with a mould release agent.
Temperature is important to the chemical processes involved, so work in an area that can be maintained at around 20 degrees. You will also need adequate ventilation because the fumes can be dangerous to breathe. And you will want to wear latex gloves to protect your hands.

Fraser Cars – low flying into the fourth decade

10 July, 2026

With almost three and a half decades under its belt, Fraser Cars is one of New Zealand’s longest-surviving car manufacturers. The company first opened its doors for business in 1988, during the boom time for kit manufacturers. During the ’80s, around 40 different companies were building kits and turnkey cars for this niche market. Of those, only Fraser and Almac Cars (established 1981) are still in business today.
Most of the new kit car companies were killed off in the cradle by the threat of new legislation that never eventuated and definitively by the sudden availability of high-performance Japanese cars when the floodgates to second-hand imports were opened. The now long-retired founder of the company, Neil Fraser, first came across Lotus Seven replicas while racing Lotus Cortinas in the early ’80s. He regularly found himself racing against a little Caterham, a Lotus Seven–styled car built in England. He was very impressed by its simplicity and handling. In 1986 Fraser built his own Lotus Seven–type car, using the knowledge he had gained from several close looks at the Caterham.
