I build boats with tungsten
Carl Dau trolls:
Anyone experienced with tungsten-boats? Stephen Baker wrote: I actually started pricing up a tungsten bulb for a boat. About 9,000 lbs. NOBODY had that much lying around, and by the time I finished calling round all the suppliers, the price had nearly doubled. My theory was that they were all calling each other looking for more, nad the old "supply and demand" thing kicked in. Believe me, we eventually built the whole boat, with conventional ballast, for half of what the bulb would have cost. And the tools to shape it would have added considerably to the cost. The only way to go with shaping would have been to make sintered disks and bolt them together. This may not be so easy for a hull, and the weight (50% MORE than lead by volume) makes it unacceptable for most uses. Kind of makes me wonder... why haven't we seen any tungsten keel bulbs in really hi-dollar boats, like say for example the America's Cup? There was one boat with a fancy keel including a mercury column, so that the center of gravity could be raised for light air. That must have been pricey. DSK |
