    Why deadly depleted uranium is the tank buster's weapon of choice https://www.theguardian.com/world/2000/may/18/armstrade.kosovo

    well since the UK/US govts feel there is no problem shooting it into places where children play with it, I figure that a lead lined bulb ought to be able to contain any remaining particles from escaping the bulb. Perhaps I should just visit Kosovo with a metal detector.

    Obviously someone used it for a keel, this thread is about sourcing heavy metals for peaceful use. All leads appreciated

    The only "leads" you need, are the Pb variety, stop playing silly buggers, it appears to be your favourite hobby. :rolleyes:

    How many tons of gold do you need? Market price this morning was around $64.3 million a ton, plus shipping.

    Well since I mentioned the buget for this project was billions, Gold cost is not a problem, its the shipping, as you would know if you tried to put a few bars in your suitcase. Apart from that, its just not heavy enough.

    no, just light hearted since everyone here seems to take themselves so deadly seriously.

    So back to the topic. leads for ballast material suppliers IYP )

    We don't ship on suitcases. What is the amount you need?

    Annode, when are you going to show us even just a rough sketch of this mythical boat that you are designing?
    Or is this whole exercise just a big wind up?

    He's been trolling the forum with ridiculous ideas and claims for quite a while. Don't take him seriously. Perhaps you can use these posts to practice your sarcasm :rolleyes:

    This thread is starting to remind me of one long ago where a poster claimed he had the money to build a helicopter carrying submarine...The consensus among the professionals then, as should be now, is "show me the money". Most unreasoning things like this are possible for a price. I will never disbelieve anyone...but I'll take the money up-front to believe fully...cashiers check please, and in my accounts first.

    Pb is worth about 2USD/kg as scrap. The days of collecting free lead are over. A scrap boat with a lead keel has a base value of (lead weight x 2USD) - (removal + disposal of the rest). This value can of course be negative, but that does not mean somebody is going to give it away for free.
    Tungsten alloys (Densimet, Inermet, etc.) can cost up to 200USD/kg depending on how much you buy and who the supplier is. Since they are sintered alloys they are not approved for structural applications.
    DU has no value because it is not for sale. You either have the connections to get it free or it's unobtanium.

    I was in US Navy Deep Submergence. We looked at using a Tungsten forging once because we needed the strength and the weight...come to find out the material needed to do the rough forging was 4-5% of the US tungsten consumption for an entire year...we made it out of K monel.

    Pure tungsten in billet form is expensive (much more then 200$/kg) and hard to find, has to do with the refining process and limited applications. The sintered alloys are commonplace, for example non toxic birdshot is made out of it.
    The chinese dominate the tungsten market, when they closed some factories for upgrading to better environmental standards the world price doubled.

    Not a windup. No. Rough sketch I already posted.

    note the choppy waves!

    Gold for ballast has other problems:
    On April 5, 1933 President Franklin D. Roosevelt, signed an executive order which outlawed the private ownership of gold. To justify the seizure, FDR used wartime authorities under the “Trading with the Enemy Act of 1917”. The law was never repealed after World War One, so Roosevelt used it to declare a national banking emergency. Roosevelt’s order demanded that all Americans must surrender their gold to a Federal Reserve Bank by May 1, 1933, less than a month after he signed the executive order.

    I doubt the Govt is going to seie depleted Uranium tho... so who knows an arms dealer ?
