If I understand what you are saying the plate itself is not flat??? Without any inserts and plate out of the table try the same thing and see if when the square is on just the plate are the sides still down by 1/16" or so..... if so the plate must not be flat. If that looks flat then try putting one of the inserts in and trying the same test if it still looks flat then it is table related but if the 1/16" thing only happens with the insert then the insert is the issue..... What ever the case a chamfer is not the solution.blairrm said:If I take a straight edge across the the table and adjust the plate so that the center ring is touching the the stright edge. The outside edges of the plate are approx 1/16 below the table surface. When routing shorter stock, the end will tend to catch on the small lip/edge of the formica, as it leaves the plate.
Maybe I just need to chamfer the formica edge to let the stock move over the lip ?
