Re: Weighing Freight Car Models with Liquid Gravity

While tungsten is more expensive than lead, and may be harder to work with, it is definitely heavier for any given volume … nearly twice as heavy. I thus disagree with you that "If you have enough space for 1 oz of tungsten or titanium you will almost always have enough room for 1 oz of lead”. Just NOT true. You need only a bit more than half the volume of available space if you use tungsten. That’s often critical when trying to weight a flatcar or other "problem” rolling stock.toggle quoted messageShow quoted text
And, as for titanium … it’s relatively light and not at all suited as a weight. I mentioned it only as another difficult-to-machine metal. Both titanium and tungsten CAN be machined, but not with the tools usually available in home shops. For most, to use tungsten you need to buy it in a useable form.
