Anyone got some advice on the finer points of setting up a router table for milling strips?

I have been milling some more strips to finish off my Razor Billed Auk deck and ran into an issue I couldn�t explain. As I send the strips through my router table cutting beads, the last one inch of the strip seems to get a extra 1/8� taken off. I have not had this problem before and am using feather boards on both sides and above the bit.

Obviously this isn�t a big problem to cut off the last 1� but I was curious if anyone else has had this problem. I am assuming that it has something to do with getting the fence parallel to a tangent of the bit but I kept getting �snipe� on that last 1� no matter how I fiddled with the fence.

Regards,

Jack
