Every once in a while I have to weld something. It's stupid, I know, but when it's peeing down rain and it's just one little bead. I do it first thing in the morning and then I'm paranoid(with good reason) the rest of the day. I too need a dust collection system. Right now I wait for a windy day, open all the doors and windows, and walk around with a leaf blower stirring everything up. I'll be reading this with interest.
