Herb, I understand where you are coming from in terms of the dust issue.
Nearly all of my dirty work is done outside with the exception of what is done on the belt linisher and pedestal grinder as they are fixed, that said I tend to keep there use to a minimum in any case.
Most of my stuff is on castors for that very reason, I have an apron in the front of the shed where I do the majority of my fabrication work.
At the end of the weekend I always spend 10 minutes vacuuming, wiping over all my bench tops and just giving things a general tidy up, putting things back where they belong.
Cheers
