Toolmaking Chair Type Edge Finders

In this video we take demonstrate and fabricate two styles of old school jig bore edge finders. These unique edge finders make use of a test indicator to establish a zero point on an edge. The units shown in the video are copies of Pratt and Whitney and Moore type edge finders. They will be heat treated, ground and lapped in a future video.
