Yabbut, this is a cut on a router table. Chris, what thickness is your
template? It would seem that your template would be reasonably safe
from trimming if it's 3/16ths or thicker, even when switching from top
bearing to bottom bearing, with only a good eyeballing of the cutter
height. A few thousandths of sanding doesn't sound too bad, however.

You have a better chance if the cutter is 4-8-10 mils smaller than the
bearing.

the portion of the template that you cut the previous time, no? The
only way I can see that happening is if you're flipping your templet over.

If you run the bearing against the same portion of the templet all the
time, how does the templet get trimmed?
