Hello!
I've read Bill Pentz site recenty, but don't understand one thing. He told, that we need fine dust collection, that chip collection is not enough, so we should always wear dust mask + fan.
OK, suppose I purchase some good cyclone and filter outside, does it change the situation ? It seems, that even with good cyclone, lathe, miter saw and hand (power) tools can create a lot of fine dust, difficult to catch with cyclone. This means, that even with good cyclone we need to wear dust mask all day.
But if dust mask still required, probably it worth to spend money on really good mask (like 3m versaflo) and use basic chip collection ? Wear comfort should be much better and basic ventilation/ceiling air filter should reduce persistent dust level in workshop.
