Product Example 13: Depth to an Internal Gage Diameter

The Dow-Gage in this illustration has a Special Stage Set which utilizes a spring loaded depressor rod to "square up" the part for the check.  Because the internal gage diameter is located in a fairly broad angle, the part would be difficult to settle down on the gage without this added feature.  Direct pressure from above locates the part over the gage diameter which is ground on the gage pin directly below.  The Special Set Master is shown at the left.
