Well the fume system works. I bought a Fantech as @RSJB18 suggested on page 5. I was nervous as heck to drill through my siding but it worked just fine. I hooked it up before I started spray painting. Constantly spraying 35' of duct gave it some work to do. The smell is there but it's only in the basement. You can't smell anything upstairs. I also fired up the test layout to see if it would pull the smoke and it did. The smoke drifted over to the nearest uptake. I will need to dampen the uptake nearest the fan though. The pulling isn't so strong at the farthest uptake. The noise isn't too bad either. It faded into the background when I started two trains up at once.
That leaves the matter of 18" worth of masonite and a backdrop to hang. Then it's benchwork time.
