Using a guide such as this also allows you to flip the guide around and use the dado you just cut as a guide to recut the previous dado. This will make sure your dados are parallel and eliminates future problems with the fence guides binding. However, if you don't have such a guide, another option would be to carefully set up a router guide using the first dado as your reference point (again, maintaining the parallelism) as shown below, then cut the second 1" x 1/2"-deep dado front to back. You're now ready to cut the 36" channel extrusion in half and install the channels into the two 1"-wide slots. While you have the router set for a straight cut, readjust the depth and cut a shallow rabbet on the right edge to inset an adhesive scale flush with the surface. My scale was V2" wide x V16" thick; yours may differ. After making my centered 3/4" x 3/s"-deep dado, I cut both the side 1" x Vi "-deep dados using two passes with the same bit.
