Very interesting; thanks for the pointer.

I wrote to Brian that I am sure there were cars with BCR ends and black ends.  Model to a photo.  So now he has a photo to justify his modeling work.

I have sent to Brian a photo of 78601 privately. It shows a reweigh date of 3-57 and has a nice, new, shiny paint job so I assume it was painted 3-57, too. It is clear that the ends are the same shade of boxcar red as the sides.

Aaron, that is one good looking gondola. Is that the Westerfield G22 twin-pak flat-Pack version?  I'm keeping your pictures for reference for when I build mine.

Your gon looks good, Claus.  I've done something similar with some of my HO gons.

Hi Bob,
 
I've done this in N scale to a gondola by lining the inside of the gon with several layers of heavy duty aluminum foil. Then use a small soldering iron to heat the inside of the gon and, when the plastic is softened by the heat, press to bulge it out a bit. Locate the bulge in the center of the chosen side panels, since that is typically where the prototype is most likely to have a bulge. I also dinged the top chord, simulating damage due to dropped loads or dropped pieces of scrap.
 
You can see the results below - the gon looks like it is on its last legs! Hopefully the link works...

Making Dents & Bulges in Plastic Cars - Techniques?

Allowing for differences in plastic composition and thickness in HO scale hoppers and gondolas, what techniques do those of you with experience recommend for creating dents and bulges in such cars?

I am especially interested in temperature ranges and choice of equipment used for softening plastic.

Thanks.

One can carefully gouge the inside between panels with a motor tool behind the bulges.  

In my observation, the sheet metal bulges but the structural members of the car are much more robust on prototype cars.  

On this car the sides use the ACC bulges.  The ends were gently bent after the car was immersed in hot water.

For a loaded gon I’ve built the panel’s up with thick super glue to replicate bulges. Of course if the gon is empty this doesn’t work on the inside.

I vaguely remember Allen McClelland did an article way back in RMC about doing this.

Um, no one advocates melting. Softening and bending are very different from melting.

I’ve never seen melted plastic look like bent metal. The two materials just don’t bend the same way. YMMV. I do recall some fellow ten years or so back that replaced all the plastic panels with thin aluminum or copper foil, and then dented that. Lots of work, but looked great!

Making Dents & Bulges in Plastic Cars - Techniques?

Andy Carlson
 

Years ago I came upon a most realistic warping of a steel freight car side when I wasn't careful in mixing the two components for a urethane pour into the box car side's mold. After removal from the mold, I had the most beautiful distress that I felt was worth replicating. None of my purposeful attempts yielded anything close, often I had swerls with uncured wet spots of resin. I suppose continuing experiments may lead to the discovery.

Resin is far more forgiving. Styrene gondola sides are too thick, and the plastic is difficult to control when you try to manipulate it. Resin is usually far thinner and has memory, so if you don't like what you've done just warm it up again and it bounces back.
