I have a harvey saw that had an overhead dust collection system that came with it. Was ok, but lots of dust escaped. I bought the harvey shark, and hooked it to an old 1 1/2 hsp dust collector. I was amazed at the dust collection. I get about 8 little tiny pieces on the table after a rip. The only time it doesn't do well is when I'm trimming an edge that leaves one side of the plastic cover open. Even then it isn't as much as any other method I've used. None of it blows back into my face/and I can't smell wood dust anymore. The thing is built like a tank. As a 74 yr old woman, I struggled a bit with the heavy parts, but really had no issues with getting it installed.
Be the kind of woman that when your feet hit the ground each morning, the devil says, "oh crap she's up!"
