Ianwater – Nice!
I had originally thought about mounting the blower directly on top of the cyclone too. The problem is that the outlet on blower takes 5" pipe to go into the final stage of the dust collector and I was not going to wait to have it shipped in. With my current setup, you can see the connection is pretty much straight in with a piece of flex that I had from the single configuration, and the 6" pipe that I needed between the cyclone and inlet on the blower can be found at pretty much any hardwares store.
