“Main rods are never "jointed".“
Heres a picture of what I’m calling a “jointed” main rod. I have no idea what it’s supposed to be called. It allows much more side to side play than a “solid” main rod.

I don’t understand what you mean by retrospective. I’m not claiming anything. Look through eBay and the encyclopedia that Brass Trains.com and you’ll find many small engines they have done and are available on the second hand market. If you’re trying to get a “rise out of me”, you won’t. LOL

“There was a fellow on what forums? Who is this fellow?“
His name escapes me as he changed it all the time. I think it was Hal and he always added something to it like Cactus Hal or Engineer Hal or some such nonsense. He was pretty obnoxious. He had a loop of track on a board that had a bunch of what I think were fiberglass garden rocks and sand. One thing that he kept harping on about was Walschaerts valve gear. Couldn’t have a locomotive with it! Have seen him post lately anywhere so he’s either died of has been tossed off all the forums. Scott Mann lists the minimum radius for his 2 rail 2-6-0’s at 48.

I fail to recognize how the current discussion has anything to do with Lee Marsh GS-4 and GS-5s. Maybe another thread on minimum radius for various steam locomotives is in order rather than discuss it here?
I’m with you Jonathan. It’s gotten a bit off base. My original point was smaller nice locomotives for people with less room vs all the new prospects being talked about were all big needing 70+” radius.

Would love to see some produced!
You can always hit the "report" button.
Peter, a main rod connects the crosshead with the main driver crankpins. Your photo shows a two piece side rod. That does allow lateral motion, but so does a solid side rod if there is a tiny bit of clearance on the crank pins. Real side rods are articulated at a clevis, usually off the crankpin a bit.
bob2.
What does the report button mean/do?
Peter
It alerts the moderators when a thread drifts. So, by the way, does the word "moderator."
IMHO, a little Thread Drift makes life interesting! LOL. As long as it’s about 2 rail o scale trains.
Peter
If you think about it, almost all real life conversations drift. Classroom and business meetings do as well, although in those settings it is counter-productive.
Here, drift indicates that the original topic has exhausted itself.
