Image Description - 0713-3 A black and white figure shown in perspective view is captioned "Figure 3. Fitting Master Tool to Transfer Gauge". The figure shows a partial cross section of two circular flanges. One flange is the transfer gauge described in the previous figure. A smaller flange called "Mastered Tool (Drill Jig)" is positioned concentric to the transfer gauge. The outside diameter of the mastered tool is smaller than the outside diameter of the transfer gauge. Three thru holes drilled on equal radii. The three holes on the mastered tool contain potted bushings, which are installed using a potting pin. A check pin is also shown which is used to verify the exact location of each hole.
