I simply drilled out 3 matching 1/4" holes in my G-10 rotary disc to match the tapped holes on the bushing and screwed the disc to the bushing face via these holes with proper size/length bolts and lock washers.
David, how did you ensure that the center of the bushing was concentric with the center of your disc?
I'm using a shaft arbor right now, which means a hole in the center of the disk (pretty easy), but I can't for the life of me figure out how to layout the holes on the disk to correspond with a bushing hole pattern without having access to a mill or an X-Y table. .
