Thanks, Dave. Very interesting.
I don't really understand why the abrasive is drawn into the cutting head. If the diagram (at the 12:06 mark) is accurate, I don't think there's a venturi effect, because there's no change in cross-sectional area in that part of the nozzle. Some other effect, I guess.
