James and Edward, thanks very much for these points. I'd never even thought of them! The return is some 8 feet down an open hall from my workshop room. In response to James' point about air filtration: The filter on the forced air machine seems to be kind of middle of the road in terms of quality of seating, etc. In the past, I've had some problems with rusting file cabinets in the same room as my workbench, so I'm planning to saw outside, as much as is feasible. But if the neighbors are put off by the noise of hand-sawing (six year old on one side of townhouse and 1 and 3 year olds on the other - all still napping presumably) then I'm going to be pretty stuck unless there's some good option for controlling the dust from hand-sawing. Ah, there's one more option: I can do the rough milling and sawing at one of the three relatively nearby maker-spaces. I'm very fortunate to have them!
