I keep seeing it repeated (and repeated and repeated) that you need more cfm to collect the fine dust than the larger chips. Can anyone point me to where this is documented, not just who originally repeated it? Or at least a calculation of why. My rational brain would suggest the opposite. Table saw as a case in point. The tip speed of a 10" blade at 4000 rpm is 119 miles per hour. The blade produces chips and dust of varying size, presumably ejected at 119 mph. Grab a handfull of chips and a handfull of sanding dust and see which you can throw the farthest. Wouldn't the heavier chips travel further, just as a baseball will travel further than a shuttlecock when hit by a bat? Wouldn't it be more difficult to collect the fast moving chips? With my DC running, I am more likely to see chips at my feet than fine dust in the air when I am not able to use my table top collector. Nuts, I'm confused...help me out here.
