Paper Abstract
In March 1985 a 1.8m diameter, f/1 focal ratio, lightweighted honeycomb sandwich mirror blank was cast at the Steward Observatory Mirror Laboratory. The front surface curvature was formed by spinning molten borosilicate glass at 15.6 rpm. The purpose of the casting was to test the method to be used to make 8m honeycomb mirrors. The blank will be used to test a polishing method for f/1 paraboloids.
