Every millisecond has been accounted for in an eight-year project worked on by seven time-smart Whangarei men. The result is a perfected, full-scale model of the About Time ball clock sculpture, a feat of engineering which will be replicated in permanent format Whangarei's Town Basin. "It's got to be really top-notch construction," About Time committee member Peter Romer said.

The seven volunteers, with a mix of engineering and design backgrounds, have been quietly tinkering away on their ''citizen science'' project at a warehouse space on Reyburn House Lane. Now they are inviting the public in to see the model which took eight years to plan and build.

It has four main rails: one labelled with seconds, two with minutes and one with hours. Thirty-five 115mm diameter balls speed around the large structure, which is 6 metres long, 4m wide and 2.5m tall.

The top rail receives a ball from a ratcheted electronic motor every 15 seconds, dumping it onto the rail below every minute, while the other balls disperse. Every 10 minutes, one of the ''minute'' balls drops onto the 10-minute rail below, while every hour, one of those balls becomes an hour marker.

Confused? Imagine trying to build it, complete with a washing machine motor and series of cogs that must deliver balls at precisely the right moment so the clock will continue to run on time.

The clock also includes a section designed to teach people the basics of physics, including a small lifting version of Te Matau A Pohe Bridge and a pedalling metal man who needs a name, Mr Romer said. Article from NORTHERN ADVOCATE 9 Jan 2017 11:30 am
