Flush Trim Bits work best for a planer job on the router table but if you don't have one or you want to just kiss the edge of the stock with a carb.spiral bit try this, move the bit up in the router table until you see the 1/2" shank of the bit then lock the router and use a brass setup bar or flat stock and zero the bit (just the shank part of the bit) to the fence now move the fence Back just a bit then lock it down now unlock the router and drop the router down in the table util the cutting part of the bit shows then lock the router and run a test to see if it takes off what you want.
Just a NOTE*** you may want to stick some doubl.stick carpet tape of the left side of the fence, but leave the white part of the tape on,this will give you about .010 offset to help with the snipe at the end of the cut.
Then just pull the tape off when your done.
