Re: Making Dents & Bulges in Plastic Cars - Techniques?

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.

Re: Erie 78500 series boxcars

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.

Yes, the Des Plaines cars came with black ends.  I looked at mine (unbuilt) to see.  I believe that they were modeling the as-delivered paint.  Mike’s comments about your modeling era ring true, but I think it’s more of an issue that depends on the particular car – some didn’t get repainted for a long time, and there could be >>weathered<< black ends well into the 50s.

 

It’s also conceivable that some shops might have repainted the car and left the ends well enough alone, or might have renewed the black car cement.

 

As I realize you know full well, best to model from a photo . . . which can be pretty hard to find.

Thanks Mike and everyone else who sent me information on and off list.

 

I was working on the kit at a show this weekend so I didn’t have most of my materials.

 

 I believe what I’m going to do is paint the entire car freight car color and letter it as a reweigh/repaint date in the mid 50s. 

 

I have one of the older Des Plaines cars. But I wanted to do another one. I think des Plaines did theirs with black end but mines put away for the moment.  The Desplaines car was also one of my earlier ones it’ll probably go into the upgrade queue. I think it might even have Kadee air hose brackets, yuck. 

 

Now to determine if the running board was painted. 

 

Also, it looks like intermountain had eight rung ladders with the integrated step so I think I have some of those, otherwise I will try pierre’s ladders

Hello Brian & Group!

 

In the several responses to Brian's two inquiries about ERIE boxcar painting practices, I believe his basic question has not been resolved, that is:  what would be the color of the repainted ends on the 1940 built 78500-78999 XM cars in the mid-1950s?

 

From my collection I found no help (yet) from boxcar lettering drawings.  Only the stenciling and monogram are referenced with no mention of 'body' color.  This is not the case for other drawings.

 

Several photos in my collection from even the mid to late 1940s suggest that the ends were being repainted in the FCR of the body.  However, new cars were being delivered in the mid-1950s with the black ends.  It would appear that any boxcar repainted by the RR did not receive black ends.  My own (late 1950s and beyond) experience viewing cars on the hometown ERIE did not present black ends at all but photo examples can be found after the 1960 E-L merger.

 

I believe this question has been addressed in the past by the ELRHS but I am not presently able to review that  in back issues of their Diamond but perhaps others have the pertinent ERIE documentation.  For your your needs you would be very safe going with FCR ends on any ERIE boxcar repainted before your late-1950s modeling era.
