The really thin hand plane shavings end up going into the clear bag on my HF 2HP dust collector along with the really small particles or "fines". The first time I bum rushed the seperator with a big pile of shavings, it clogged the output hose going to the impeller. I cleaned every thing out and took it slowly after that and didn't have any problems. None of this stuff likes paper towels, either BTW. The main thing to remember is that you will not be throwing your dust pan away. That won't happen with any dust collector system. I keep my broom, dust pan and trash bag nearby. It's much quicker to sweep a huge pile of shavings into the trash and then suck up what's left behind with the DC. Just my benevolent opinion.
