Working on bringing an out HO layout back to live. I just build and installed the Wathers, 90’ motorized turntable, 3 stall Roundhouse, and in the process of building the Machine Shop. I think it would be cool to have some sort of smoke device built into the Machine Shop smoke stack. Does anyone know if there is something like that out there?
HOWEVER on mine I use ultrasonic misters with a small fan. Less smell, more “steam” and it’s harmless water, not an oily residue. They are uber cheap too
