Most of the time pin punches do their job and pins push or are drive out with modest effort. Once in a while you really have to wail on them to get them started moving. When that happens the average pin punch just folds like a cheap suit.
With this in mind I've been thinking about making some for special applications. Use my regular el-cheapos formost normal applications, but break out my "special ones" when the pin needs a little more push.
So, what would be a good choice for the application? W1 drill rod?
4140? I have those on hand, although either would require heat treating, and the drill rod would probably require heat treat and tempering. Is something else better?
