re: Dust control with duel sliding compound miter saw

I have seen people build a backsplash that tapers to the centre then the vac hose is attached to that. Also try spinning the blade up for 3 seconds or so before making the cut to get the air flow moving before making dust, then move the hose to where that air seems to be strongest. Myself, I use a dustmask, goggles, and a face shield, then I have to clean them every 5 cuts or so.
