The handrail conundrum
Here’s a puzzle for you. Take a look at the first photo below. Note that the handrail is bent between stanchions. Also note that there is only one connector, at the extreme right. The handrail looks to be a single piece as it is bent to go over the sander pipe and to accommodate the tapered boiler course.
Now I presume that the handrail stanchions are screwed onto studs. If that’s the case, how did they assemble this? If the stanchions are not screwed onto studs in the boiler, they would have to have been put onto the handrail before it was bent, and there would have to be some sort of setscrew to hold them onto the stud. But I see no evidence of any sort of setscrew. Note the photos of a similar locomotive with a better look at the stanchions. No setscrew visible (unless it's on the top side).
So how did they do that?

Re: The handrail conundrum
Greg,
My guess is the stanchions are actually screwed into the sheet metal boiler wrap. then the handrails are inserted before the wrap is installed and everything is sort of kludged together around the boiler. My Ottaway has the handrails attached in this manner, directly to the sheet metal, not to an underlying fixture. Yet they look and act quite solid.
If the handrails are attached to a solid frame underneath, then it must be possible to insert the handrail from one end and twisted to and fro in some way, to worm its way through all the angles, to come out the other end.

Ah ha! I'll see if any of our vendors stock that.

Re: The handrail conundrum
While on the subject of handrails (and posts) can anyone point me to drawing of a well proportioned ball head, tapered shank (etc) post? I'll be looking for something I can use to take proportions from, not necessarily dimensions.

Not wanting to hijack Greg's thread, but if you consider the stanchion below to be well-proportioned (and suitable) then I'm happy to PM you the dimensions. Let me know.
Best regards
Steve

That's great, Dick. I'm going to start a new thread with details on how I made my columns.

Re: The handrail conundrum
From a manufacturing practicality standpoint=> I would make the handrail in sections..bent to fit.
Ends drilled (or it is pipe to begin with) with internal sleeves to provide alignment..with the joints directly under the balls...or the joints are there in plain sight covered in paint and rust.
