A large cast-iron castings underside is being machined in one of B&C’s telescope assembly pits.
There were 121 identical holes machined in the casting to hold an array of optical collimators.
The collimator holes all pointed to a common focal point reference target field.

40 Inch (1.02 meters) Telescope for Siding Spring, Australia

Don Winans, Boller and Chivens Telescope Assembly Supervisor in L & F Industries’ high bay assembly building.
Future 36″, 40″, and 48″ telescopes were assembled at South Pasadena plant.

In the early 1960s, the Australian National University established a new astronomical site at Siding Spring in central New South Wales, partly in the expectation that it would provide somewhat clearer skies than those at Mount Stromlo, and partly to escape the increasing light pollution of the growing Canberra. The selection of Siding Spring followed an extensive site-testing programmer organized by the then Director, Bart Bok. The new site was instrumented with three reflectors of modest size, all made by Boller & Chivens. The 40-inch is the largest of the three. The other two being a 24-inch and a 16-inch. It has proved a useful instrument especially for photometric and imaging work.
