The problem is how do we machine the back of the shaped component? You
may think this is difficult, but all you have to do is hold the shape against the
fixed jaw of the machine with the flange against the moving jaw. Then you can
machine half of the work to the correct finished size using an end mill or sim-
ilar. Invert the work in the vice and machine the other end of the component
to the finished thickness. You now have a shaped component with the flange
removed. Rub on a flat sheet of wet and dry paper to clean up the finish ma-
chined face.
Milling a radius in the vice
We have a short strip of metal with a hole in the end and we need to form a
radius at the end of the strip. Put a bar through the hole, and drop it into the
vice at about 1 degree below horizontal. Mill across the top of the bar where
the radius is to go, lower the end to 2 degrees and mill across again. Keep
doing this until the radius is formed right around the end of the bar. Deburr
and clean up the radius with a file.
