Mike, you got it in one. I built this from two layers of 1 x 6" that extends over the table edges by a couple inches on each side. The reason I made this from two boards glued together was to reduce warping, I think using a 2 x 6" would not stay flat. I started by marking the center-line and cut a 2-1/4" through hole about an inch from one side. Next I used a 3/4" straight bit to cut the clearance for the bits/bearings about 1-1/2" into the opposite edge. Making multiple passes I cut the dust channel about 1-1/2" wide x 1" deep. I jointed the edge to remove the slight tear out. I trimmed the angles and removed the rough edges with a sander. This was an experiment that turned out great. This simple fence does a really good job at capturing virtually all the dust. The reason I started with the 2 x 6" width is I figured the soft pine edge will get messed up with use. This can be jointed many times to provide a clean surface. I am going to make a couple more of this style of fence: one for jointing and one with a tall board added to the edge. Quick, inexpensive, easy to swap out... I really like the concept.
