My band saw dust collector had never functioned effectively because the 2″ exhaust pipe was too small. Then I stumbled upon a PVC toilet flange in our local hardware store that exactly fit the 4″ hose from my dust collector. I drilled some starter holes, then cut a 4″ circle out of the lower door with a metal-cutting saber saw. I then drilled 5/16″ mounting holes, deburred the sharp edge, and mounted the flange. The fit was so good that I didn’t bother with a gasket or seal.
