PRECIPITATORS - Part 17

Well, still haven't rotated the model 90 degrees yet to work on the next side, but I think I might tonight.

A furnace dirty gas main and bleeder stack
Work on the platforms of the bleeder stack included some caged ladders and railings.  I've been called to task more than a few times on these platforms as the caged ladders are in line and, what I've been told, they would be skewed right or left at each landing or platform to prevent someone falling all the way down.  I built it as it was on the prototype, and the ladders are inline on that.  They aren't on identical other bleeder stacks at Bethlehem, but on A-Furnace they were.  If you don't believe me, most of the bleeder stack is still there so look for yourself.  Maybe some fabricator made a mistake.
A-Furnace - Bleeder stack on left - top section and one platform has been removed
So far the railings are built from what I can easily reach.  I also worked on the platform that is on the elbow of the dirty gas main from A-Furnace.  It had an interesting structural support structure, as well as a caged ladder on an angle.

the wood dowel thing seems to work well, i gave it a try and so far ive noticed making elbows is so much easier with wood than plastic, despite the extra weight and the possible need to prime it, Im going with it for most my piping needs now.

I've been going back and forth Jeremy. You are right though, the dowels are easier to make elbows with and if you use yellow glue the joints will never ever separate like with the plastic. In hindsight I should have primed the dowels first as if you use the Rustoleum Grey auto primer you can sand it between coats and fill any grain in to make it smooth like plastic. I can still prime, just some of the section it will be hard to sand. Also, be sure to find the older style poplar dowels. Many of the new ones I see, like in lowes or home depot are some sort of weird chinese wood that has a lot of open grain.
