I have a tall fence (6"-8" high) I made for the router
table. It's held up off the table by about 3/4". I use it
with a straight flush trim bit to trim off panels with solid

bearing on the flush trim bit allows you to not be super

It's a little bit of over kill for a veneered edge though
it's easier than trying to balance a three horsie router on
