No, not discussing the edge guide. The sub-base should have a round hole to install bushings that the bit would go through to keep the bit away from a surface, such as using an inlay bushing.
I just purchased this router with both bases. The plunge base's sub-base is not designed to hold bushings. It looks as if an adapter is required. I am not able to find this adapter anywhere. Is the adapter available? Is there a sub-base for the plunge base that will accept bushings?
