roamer46 wroteI have thought about it. I even brought a big window unit to the boat. But the dusty environment is a problem, and not having a door or portholes poses challenges, too. The biggest issue is electricity, or the lack thereof. The entire yard is supplied by a single 25a slow-blow breaker. I couldn't run a saw, the dust collector, and the AC at the same time, and neither could anybody else.
What sort of dust collector are you using? I have one with a 5" hose between the blower and the filter/bag assembly, and found that it can also serve as a dandy paint-fume / heat extractor. I simply disconnected the hose from the filter unit, and vented it outdoors. Works like a charm to keep dust, fumes, and overspray out of the finished bedroom adjacent to my project. In my case, I made an input-filter box with a furnace filter to help keep overspray from getting into my DC fan. For spraying shellac, it works so well that I don't need to wear a mask. (Time will tell if the same is true for the lacquer topcoat.)
I got this one really cheap on CL, because it has a 3-phase motor. So I stuck a VFD on it. The beauty of that is the variable-speed control. Crank the speed down just a bit, and it gets very quiet. When not spraying, I can turn the speed down to 20%, to keep from sucking all the heated or cooled air out of the house, and still vent fumes while the shellac dries. That exhaust-vent panel mounts to the window in place of the regular window screen.
