Tools for the Workshop

Abstract

An aid to co‐ordinate setting, in the form of an optical depth control to the travelling spindle, is now available for Kearns Series 45 or 72 horizontal boring machines, and No. 2 or 3 Kearns patent horizontal boring machines. This system employs an accurately graduated rule and large projection screen, measuring 4 × 1½ in., thus completely avoiding eye strain caused by peering through a microscope.
