Finally - got it done, except the BS. As everybody says, "This thing sucks". It's a HF 1HP with 5 Micron bag. Not so sure about the bag thing, seems to create a small reduction in the suction power. I know I've seen some pc's of others out there with some kind of filter thingee on it, but can't seem to find a source for the one I've seen in any of the threads, missed it somehow. Any advice would sure be accepted. I'll send pics, as soon as I figure out how.
