So, VERY roughly, Platinum is $10,500 a pound, gold is $13,000 a pound, tungsten is $75 a pound. And lead shot is $10 a pound. And steel is pretty much free. And apparently, if you're the right

Here is a source (one of many, I am sure) that offers lead shot in 5 pound packages: Lead- MidwayUSA Lead- MidwayUSA Midwayusa carries a full line of Lead products

Cerro Bend or Asarco 158 are useful metals but they do expand when cooling. The material has been known to split open more than one locomotive boiler and freight car. Gene Deimling

Cerro bend melts in boiling water its good stuff. Can you get liquid lead in the US very fine bird shot stick it in with pva. These days i use coins they are pennies clean and easy to use. Paul

Perhaps no one has offered this as a possible solution, but I have always used tire weights. Not sure if they are pure lead, but the many that I have are easily cut down to the size needed. Always

Tungsten is also expensive. Depleted uranium is also dense but very hard to find and probably expensive. Some of the best material is Cerro metal but again expensive. Cerro

I would echo Bruce’s comments (though he intermingles PFE and SFRD, causing a little confusion). The produce regions served by the ATSF (and PFE) generated produce that was in demand across the

Hi all, I didn't know about this web site (or had forgotten it?) until Ben put a link to it. Thanks Ben!!! I spent a couple of hours yesterday bouncing all around that web site (time

Jack, I understand and always support the search for photographic evidence, and you have gotten some, but something about your question troubles me. From a practical standpoint, I think it should be

Hello Mr. Rindfleisch: If you are still looking for a few pounds of lead shot, please contact me at westerfieldmodels@.... I have some #9 shot. Thank you, Andrew

Tony, I have the 1943 CBC, which contains an R-40-10 drawing. Do you have other car drawings, too, in the PFE book? And, is the PFE second edition (the one presented at Amazon) the latest? I see,

Got it. Thank you Ben. Jack Dziadul Sanford, NC Tracks to the Triangle 2016 Tracks to the Triangle 2016 We will build on the very successful conventions that

Tungsten is a weighting material that may be of interest toyou. On a volume basis tungsten is about 1.7 times as dense as lead,which means you'll be able to add 70% more weight in the same space

I agree with Schuyler, at least from a theoretical standpoint. If the spheres are all of the same diameter, the densest packing that can be achieved is 0.74, i.e. 74% spheres and 26% airspace. It

The Cyc drawing and many photos are in the PFE book, Tony Thompson sent from my laptop

I'm not sure I understand your last sentence, but you hit on the important fact at the end of your second sentence. Spheres of anything, no matter how many lb/cubic inch or whatever measure you

The end looks like a variant on the T-brace end that was mentioned with a Southern box car recently. As for original, that isn't a term I would use much with LV wood-sheathed box cars. There was lots

Well, no, Ben. You can get more weight because lead weighs more per unit of volume than BBs weigh, and with a smaller diameter you can more completely fill a void. But the volumetric measure of a
