Hi, I am attempting to add a KREG router plate to my auxiliary router table. (I have a KREG lift in my main table). The top is (I think) an older incra top that is already cut for a plate. It is just under 1.5” thick. It has a rabbet cut already for the plate to sit in. Do I need to use a bearing bit to cut out the corners so that I can use the plate leveling kit? I think that I need to cut out the corners between the blue lines in the pictures below. Is that correct? Thank you, Gary
