Okay, this isn’t all that beautiful but it seems to work. I roughly sliced off the end of a piece of 1-1/2” PVC I had lying around, and roughly cut a hole in the side of the bucket. After epoxying the two together, I faired the end of the tubing inside the bucket to match the bucket side.
Another happy accident was that the ID of the 1-1/2” PVC made a nice friction fit to the OD of the original shop vac hose.
The hole pattern at the bottom of the cyclone bucket is just a goof. I’m not even sure the bottom of the bucket needs to be there but I notice that Thien separators have more or less of a bottom so I figured, why not?
