Hi Ed,
You can buy a ball end mill at Traver's tool or MSC or any number of
other cutting tool places. I tried that the first time to make the
concave cutout in the riveter nose piece with medium results. I got
much better results with a little round stone or steel cutter in a
Dremmel tool.
When I did my nose pieces I mounted the old nose piece in a metal
lathe and cut the curved spot in the face of the nose piece while
turning the lathe. For those who don't have a metal lathe handy, you
can probably do just as well my mounting the nose piece in a drill
press or even a hand drill and spinning it while grinding and/or
cutting the face. It helps if you start by marking the outside
diameter of the cutout on the nosepiece with a magic marker before
you start. This will be the same size as the round flat part of the
rivet before setting.
I went through a process of cutting the nose piece and then testing
its use on the desired rivets. I checked for the shape I wanted and
flat edges against the "Skin" of the riveted piece. Adjustments can
be made in one direction by making the concave shape
deeper. Adjustments in the other direction can be made by filing the
end of the nose piece down a little. Finishing of the nose piece can
be done with abrasive cloth or even the dreaded Scotchbrite pads.
