This is my best shot at making you laugh and shake your head. I do both each time I dust my shop this way. At a minimum, it is unorthodox, at maximum it is absurd. How did this start? I was getting frustrated one day because countless dust nibs were interfering with my feeble attempts at finishing. In desperation, I opened the garage doors, fired up my blower and blew the whole garage out thoroughly. Then I let a fan run for a few minutes and, to my surprise, the dust was gone. I guess you can put this down as one advantage of garage workshops. In my defense, it does take two minutes.
The best way to deal with dust is to have a separate area for hand tool woodworking that is walled off from machines, sandpaper, and other sources of fine dust. For a variety of reasons that I won't bore you with, that isn't feasible in my case, so this is what I am left with. Rescue me from my perversion; tell me a better way.
