Which tool is needed to make a gasket using the trace and tap method?

To make a gasket using the trace and tap method, the tool that is essential is a soft face hammer. This method involves tracing the outline of the flange or the existing gasket onto the gasket material. Once the outline is drawn, the soft face hammer is used to tap along the traced line, allowing for a clean and precise cut. The soft face of the hammer is particularly important as it prevents damage to the material while providing enough force to ensure that the cut is crisp and clean.

Other tools listed do not serve the same specific purpose in the gasket-making process. A wrench is typically used for tightening or loosening bolts and would not be effective in shaping or cutting gasket material. A screwdriver might be useful for fastening components but does not play a role in the actual creation of a gasket. Similarly, a pry bar is designed for leveraging and lifting materials, which is not relevant when creating a gasket. Hence, the soft face hammer is the correct choice for its role and functionality in this particular method.
