I would think that might be a bit difficult to obtain! Also I don't think I could cut or shape it. This is what I have found with the Tungsten. I mean Great for a standard wagon weight but a fixed size for Locos? Maybe in a bunker or smokebox mixed with lead shot? Early days. In any event 330-350g is plenty for my needs. Keep 'em coming Ray. Bouncing off each other is great but don't throw any spent uranium at me. I think we are staying with lead but if you recall the piece in the top of the Jubilee fire box weighed 11. 4g
we would have had
18.95 g/cc Uranium,11.35 g/cc Lead, 19.32 g/cc Gold, 19.35 g/cc Tungsten,19.84 g/cc Plutonium, 21.45 g/cc Platinum, 22.4 g/cc Iridium, 22.6 g/cc Osmium !
