Use an upspiral carbide bit.  2.  Make sure there is no play in the bearings of your router.  3.  Hold the key firmly when cutting.  4.  And this is a BIG one, the plastic should be at room temperature when trimming.  This eluded us for years until by accident we found that we were trimming in a cold space.  When we warmed the keys, the chipping disappeared.  Good Luck.</SPAN></FONT><o:p></o:p></P></DIV> <DIV> <P class=MsoNormal><FONT face=Tahoma size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">    Mike Kurta</SPAN></FONT> <o:p></o:p></P></DIV></DIV></BLOCKQUOTE></BODY></HTML>
