I have to use a dust mask when I power carve, scroll or turning. Just can't take the dust anymore. I don't like to use one, i wear glasses and they fog up at times. But, can't use the vacuum all the time to darn noisy. Some woods are worse, but, i do most everything in the basement, and have a good air cleaner on the furnace. Don't get to much dust upstairs.
If summer ever comes I try to do most dusty things outside in garage w/ doors open, but, with out a wind, still need the mask. Once that stuff gets down there hard to get it out.
