I have had these slot cutters for so many years I don't even remember where I originally bought them. So here is a link to Freud's assortment of slot cutters some with 1/4" shanks and some with 1/2" shanks.

Most router bit manufacturers make similar bits.

The bearing for the one I used is just below the nut in the picture of it. The bearing rode on the edge of the lower layer of glass.

As far as the trim router it's an old Porter Cable (I know they are not your favorite brand) that I have had for several years. Amazing how often I use that thing.

Actually I did the main hole with a hole saw and the smaller hole (that allows the vent portion of the deck fill to go in) with a drill bit. I just happened to have a hole saw the exact size I needed. Years of collecting tools has given me several options for most jobs.
