I am making end grain cutting boards that are larger than I can run through my equipment. Once I perform the final glue up, I use a router planing jig to flatten the cutting boards. I use a Table Top Surface Planing Bottom Cleaning Router Bit. There are very tiny ridges or lines in the piece when I use this process. It happens with several bits I have of this type. I have tried going over the piece again with the router to clean them up, but am unable to completely remove them, sanding is not having any luck removing them either. Any thoughts on the cause, or how to remove them?
