Making brass cars quite
|
Steve SANDIFER
I have some brass steam era freight box cars that sure make a lot of "tin" noise when running. What have some of you done to quiet them down.

One thing I do is replace the trucks with appropriate ones molded in Delrin or similar. They roll smoother and with choices available, you can usually come up with a more accurate and/or better looking one.

Couple of thoughts Steve:
New trucks, or at the least clean the journals with the wheel reamer tool and use new wheelsets A Kadee fiber washer on the truck bolster to damper sound/vibration transfer to the box. Put something inside the box that would dampen the sound/vibration, a block of foam. Doug Harding www.iowacentralrr.org

Now I have NOT done this but along with changing the trucks to plastic, has
anyone tried filling the inside of the car with the expanding foam product available in spray cans from home improvement stores? I think it is called "Good Stuff" or "Great Stuff" or something like that. I would think that you would intimate contact with the brass surface with excellent sound attenuation of noise coming from the body of the car. It would require great care as this stuff really expands and if over applied might rip a car apart? Humm, risk verses benefit? Allen Cain

I'm not sure I'd try that but how about foam rubber? A cheap pillow from Wal-Mart, cut up with scissors would fill a lot of cars, assuming you can get inside them.

I've used quite a number of different expanding spray foams and, frankly, I would NOT recommend it in a model. First, if accidentally gotten on the outside it is sometimes extremely difficult to remove completely. Products of this nature a made by a number of companies and in a number of formulations and some expand with more force -quite a bit more force - than others. Descriptions of the container give some idea of the expansion but ... Gene Green

Be CAREFUL! That stuff will generate a surprising amount of pressure in a closed space, and there is no way to stop it from expanding once it's in there. I used some to fill gaps under 2" pink foamboard on a portable layout once, and was surprised to fins it pushed the roadbed up more than an inch. Luckily, a Sure-form cut the grade back down after the foam was done expanding, but I could easily see that stuff popping the solder joints on a brass car. Dennis
