Thanks guys. There are lots of sources explaining the squaring up procedure, but none that I know of actually showing it. Hopefully it will help some of those who are just starting out.
And Paddy:
1) I will also start with a larger side against the jaw on parts with a thinner cross section (such as plate).
2) I seriously can't remember much of what they taught me in trade school. :thinking:
3) If you use the ball end of a ball pein, it feels like a dead blow hammer but it's a lot smaller. Of course you would never use one on a finished surface.
4) A small, square part like this is difficult to hold to one side of the vise without supporting the other side of the vise with a jack screw or a similar part. I'll do it that way with longer parts or plate.
5) I guess my finger must be fatter than yours, but I use two parallels on larger parts as well.
6) Huh? My files also cut in the forward direction and I was one of those instructors doing the slapping.
Seriously, there are many ways to accomplish the same thing so I expected one or two such comments. It's always good to hear hints and tips from others.
Thanks for the video comment. It turned out surprisingly well considering that I had to use my Canon pocket camera. My kid appears to have made off with the digital video camera.
