bob2 posted:Rods: I use .032 brass, drilled to accept small brass pins as rivets. The length is trial and error, but there is room for errors. You are not timing valves; you just want to not lock up during rotation.
I file the rods to shape by hand, and, using paper between rods, solder the pin.
As to actually forming the boiler, my techniques are ancient. I do the same thing that Fred Icken did - using brass tube. I have described it here in a Challenger thread, briefly in some old OGRs, and extensively in 48/ft O Scale News.
I can always repeat stuff - it is nice to know it gets read.
Thank you. I'll give it a try and show it.
