never needed one and have no idea of how to make one. Got to hit the ole
books to see if I ever learned anything in that area.

table the will emboss rivets into thin sheets of plastic or brass. I've
used it before, but the table is garbage. I need to rebuild it with a
real x-y table to accurately emboss a rivet pattern. Thought about using
a solenoid and two steppers to automate this one, but that's a different
story ;-) The ball mill and reverse pattern does seem to be the best
suggestion so far.
The rivet is only an example of the the relative sizes of the detail I
need. I did think of chemical milling as a possibility, but wanted to see
if there's a CNC solution first.
