From Rust to Rrroaarrr video, part 5

In the first article, I wrote about nickel welding repairs to a broken cast-iron cooling fin (parts from a barbecue hot plate), magneto check, head repair, valve work and nickel plating the push rod cover tubes. The second article was mainly about how I developed nickel and copper plating, with a little bit about kick starter repair using nickel plate on a worn shaft, and grinding teeth. Third article, the start of frame painting; engine, clutch and gearbox assembly and installation, with magneto timing.
In my last article, part four of the series, I described my efforts to rebuild the bike’s dynamo (generator) by reconstructing the disintegrated commutator, rewinding the armature, replacing the bearings and then testing. Sadly, with no success.
I have achieved a little bit of progress with fixing the fuel tank and the seat, but I have not really met any targets. When I started this series, I expected that by this article, part 5, I would be writing about fixing the famous ‘Jampot’ and ‘Teledraulic’ suspensions, and at the end of part 6, I would have re-laced the wheels, having nickel-plated the spokes, rims and hubs ready for a trial ride.

In pursuit of perfection

If David Curry was to be summed up in a single word it would almost certainly be precision. But that’s not enough – it would be absolutely vital to add artistry. Putting them together amounts to a search for perfection, so perhaps that’s the word to use.
Here’s an example: David is at present building a dauntingly complicated perpetual calendar skeleton clock, which has 38 gears, one with 165 teeth, all of which have to be individually machined. Clearly precision is paramount. But the levers and some parts of the frame look a little utilitarian, so he’s redesigning them with a few artistic flourishes. For inspiration he looks to a skeleton clock built in 1855.
“The engineering has to be right so that the parts work properly, but they also have to look right,” he says.
The clock tells the time, has a second hand, notes the day, date and month, and knows whether the month has 30 or 31 days. David is adding a second chiming system so that the half hour, three-quarter hour and quarter hour chimes have different tones from the full hour strike.

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.”
