I have an older Wilton vise that doesn't force the moving jaw downward
like a Kurt, so I tap the work down with a soft hammer as I tighten
the handle, then make sure the parallels aren't loose.

Same here. *Tap with soft hammer. *Leave them
in place.

A lead and rawhide-faced mallet used to be standard issue.

I do have a Kurt vise and I still tap the work down on the parallels
with a soft hammer after snugging the vise jaws but before going to
full tight.
