I have a POE doorbell with a CAT6 cable coming from the attic. How can I create a vertical straight channel on the side of the door to embed the cable?
I have a trim router, but it is too deep to center the channel and free-handing the cut would look terrible. I have a circular saw and a cutoff tool, but neither blade is wide enough and making a straight vertical cut that long will be difficult. I have a Dremel, but also a nearly impossible cut.
