I'm planning to upgrade to a whole-shop dust collection system in the next couple of years and I'm wondering how well it will work for collecting chips and dust created by the lathe. I figure the shavings that have a good deal of velocity in my direction are probably flying fast enough already to not be sucked up into the hood, but maybe it will help some there. What I'd really like to know is if I install the dust collector is there really a need to still wear a respirator?
