Re: Weighing Freight Car Models with Liquid Gravity

Daniel A. Mitchell

Tungsten is roughly half-again as heavy as lead … that’s significant.

In solid metalic form is is devilisly hard to work with … worse than titanium. It mostly has to be machined by grinding. But
in granulated or powder form it would be useable similar to “liquid gravity” ... hold in palce with a liquid glue.

We keep hearing guys talk about tungsten ... it doesn't "work" for me.

Although tungsten does have a higher specific gravity than lead/steel ... it is
not enough more to make a difference in terms of how much weight you can
actually add to your model trains. We don't use enough volume of weight
to make a difference.
Tungsten is, for all intents and purposes, impossible to cut/shape/size. Yes,
it can be cut/machined - but I haven't met anyone in the hobby with the
equipment to do so. I've never seen "tungsten shot".
To my way of thinking the only advantage to tungsten is that it isn't
magnetic. Neither is lead ...

Have you heard of Tungsten powder?

Or Tungsten putty?

Granted... it ain't cheap.
