Re: oil canning

Gordy: Thanks for the history - neat...? You're talking about the one I still use!? When I was a kid, my dad would say, "get the tinker, tinker, tinker can", from the sound it made.? Since, to a little kid, tools had funny names, I could probably remember that better! Since I sort of inadvertently started the thread, let me try to put it to bed - if that is ever possible on this group! The main reason for the effect was the more widespread use of thinner, cold rolled steel for side sheets.? Mills could make it just as strong but now thinner and lighter, which had weight advantages for freight cars.? The fact that change more or less coincided with the transition from riveted to welded cars is a bit of a red herring.? Like the 1930's Pullman photo I posted earlier and the two attached here, there are plenty of examples of riveted cars that show the oil canning effect.? Also, at least one company has been selling HO models with sides 3D printed to mimic oil canning for several years now, apparently not hard to model in 3D... A final non sequitur regarding the attached photo of the GAEX boxcar.? To bring it back to our home state of Michigan Gordy, you'll note that freight car is riding on Chrysler FR-5 trucks.? Enjoy!
