On my Excalibur saws, the sawdust that doesn't get caught up by the dust control will filter down onto my lap or shoes. So, I made a couple of slide in/slide out boxes and they catch what dust makes it through. That's where all the tiny pieces also go if they don't get sucked up. So far I've had good luck with finding them. If they do get sucked up, well, that's called "creative license".
