Somebody really does nice conduit work.
FWIW, I too shared my RR with a wood working shop. Three large Delta air cleaners for friable dust and two 4" vacuum systems for chips but the dust problem still lingered.
The remedy was to take the main offenders; the table saw, 12" disk sander, and router operation out to the garage leaving manageable dust for my cleaning systems.
No supposively well thought out maneuver goes unpunished. My gasoline powered tools even though covered at all times, get saw dust in their intakes.
The RR kind of took over the basement and only minor woodworking in the staging room occurs now.
