I have really been struggling with the dusk problem this Winter, what with the closed up shop and all. I got a bargan on some Padauk awhile back and when I saw, turn and sand it it makes a real mess, dusk covers everything. My gray hair turns orange and I can just imagine what my lungs look like.
I have a dust collector (that doesn't do that great of a job), two fans with filters attached on them to draw the dust from the air. I have a respirator, but with it you really have to suck hard to draw air. And, the throw-away type respirators fog up my glasses.
Now that Spring is here and I can open the windows and doors, I got two new floor fans (without filters) to push the dust away from my face and out the door.
