When is a press fit too tight?

I once had a press fit that caused galling during assembly, leading to part replacement. That taught me to check material properties and surface finish carefully. Even slight misalignment can cause issues.

How do you determine the maximum allowable interference before risking damage or failure in your assemblies? Do you rely on standards, calculations, or test fits? What signs do you look for during installation?
