A-FURNACE PART 25
I installed the two steam powered thermal expansion goggle valves to the gas washer structure. I started to build the segmented elbows and bends from 1" Plastruct tubing. This task is actually one of the more difficult things to accomplish - even with the plastics blade in the miter saw there is some chipping, maybe due to cold weather, but I'm starting to think that a better method might be a jig in a small bandsaw with a fine tooth blade. I've been thinking about buying a small bandsaw to put in the basement on my modeling workbench. The other technical problem is fitting the piping together properly - the one pipe needs to exit the structure and hit the precipitator complex at the exact same height. On the other end, the pipe exits and does a few twists and turns and needs to hit the dust catcher at just the right height. There is a piece in the dust catcher connection that I can adjust to get the height just right, but I have to work from the catcher and the venturi scrubber simultaneously to get it perfect.
