OzPoz Gallery

The OzPoz project started in May 1998 and has passed through a number of phases.
This image gallery shows progress and in particular presents images of the major components of the OzPoz fibre positioner as it is being manufactured.

The stages shown are:

Design and analysis
Prototyping
Production photographs

Note: The same technique will be used at the Exchanger sub-contractor's works for checking the accuracy of the set-up, before machining faces on the Exchanger revolver.
