Here I have mounted my router in the table of table saw. I am using a 7/32nds bit as per the truss rod instructions. Using the fence I set it up as close to center as I could by eye. I then ran the piece in about 1/4" then checked using my digital micrometer. After 2 small adjustment to the fence you can now see I am with in 1/10th of a millimeter from center. Close enough for me. The depth of the slot needs to be 7/16th of an inch. I ran to piece through 4 times. Cutting to a depth of 3/16th" the first pass then to 3/8" and the I check the depth with the truss rod. The top of the brass block on the truss rod needs to be flush with the top of the mahogany.

Routing for the truss rod
