How do you determine the correct rivet length to use when working with a cherry grip gauge?

The correct method for determining the appropriate rivet length when using a cherry grip gauge involves reading from the gauge where the front side of the structure meets the measurement markings. The cherry grip gauge is specifically designed to provide an accurate measurement of the total material thickness that the rivet will need to grip. This ensures that the selected rivet length will adequately secure the materials being joined, preventing issues such as insufficient grip or protrusion beyond the expected surface.

When using the gauge, the operator places it against the structure so that the front edge aligns with the base of the materials being fastened. The reading at this point indicates the required rivet length, which ensures a proper fit for effective structural integrity.

In contrast, measuring the diameter of the hole or securing the structure with a bolt does not provide the necessary information about the total thickness of the materials that will be joined by the rivet. Counting available fasteners is unrelated to determining the correct rivet length, as it does not take into account the specifics of material thickness that the rivet must accommodate. Thus, reading the gauge at the correct point is the most reliable and accurate approach.
