<DIV><FONT face=Tahoma size=2> Hi Dean:</FONT></DIV>
<DIV><FONT face=Tahoma size=2> After lots of trouble with
chipping during the trimming process and 150 sets of keys, here's the
recipe: 1. 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.</FONT></DIV>
