Awl --
Anyone familiar with a tool that fits in a BP (or vmc), that takes the end
of a rivet and peens it over?
A buddy of mine is being presented with a job like this, has seen it done,
but doesn't know the name of the tool, or a source.
Apparently, the tool comes down off-center, spinning, and shmears the end.

When I was a kid I ran a drill press with a rivet heading tool for a
while after school. The tool had two opposed quarter-round rollers
that mushed the protruding rivet shank into a half round dome with a
little stem in the center, left by the space between the rollers. It
came down centered on the rivet.

The process is called "orbital riveting." I've only seen it done on
dedicated machines, never on a mill, but searching "orbital riveting
attachment" returned this, among others...

No need for a special tool. Just ask JB to mount an endmill, and
tell him to indicate it very carefully. You'll get the shank end
sticking out, and a bunch of runout, and it should peen the shit out of
anything it touches.
