As an experiment, I suggest that we toss a white galoot, an African, a woman, a homosexual feller and a hippie socialist from a ten-story building to see if gravity is biased. We could drop them from a leaning tower. 2 Link to comment Share on other sites More sharing options...

Dric902 Posted November 5, 2019 Share Posted November 5, 2019 boiler explosions are hell 1 1 Link to comment Share on other sites More sharing options...
Administrators Eric Posted November 5, 2019 Author Administrators Share Posted November 5, 2019 The deadliest maritime disaster in US history was caused by 3 of her boilers exploding on a river boat taking paroled union prisoners home. As many as 1,500 were killed, but the number varies widely, depending on whose account you read. Most everyone agrees the number is north of 1,000. The boat was the Sultana. 2 1 Link to comment Share on other sites More sharing options...
Administrators Eric Posted November 5, 2019 Author Administrators Share Posted November 5, 2019 This is the Sultana. This pic was taken the day before she was destroyed, on April 28, 1865. She was legally rated to carry 376 passengers. At the time of the explosions, she was carrying more than 1,900. 4 1 Link to comment Share on other sites More sharing options...

Did anyone really perfect the 6,000 horsepower units?Are there issues due to mixing AC traction motor units with DC motor units?Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

I learned some very basic practices for welding cracks in boilers and learned enough that I never wanted to be near one that was questionable. The skill in welding boilers is to be able to compensate for the tremendous dimensional changes in the parts of the boilers, due to the extreme heating. For example, you would weld a patch over a crack in the boiler, by first bulging the patch so it looked like half a bubble. Then you welded the patch around the edges and while the patch was still very hot, you would strike the bubble in the patch compressing the steel patch so it looked flat. Now their was enough material compressed into the patch to allow the patch to stretch/expand with the heat in the original boiler. Side note: The earliest welding manuals I had, told the process to gas weld Aluminum. I followed the process and it works beautifully. I gas welded Aluminum trim pieces for a custom car I built. They polished up wonderfully and looked like single castings. Old techniques held marvelous information.

Most everyone is maxing out at 4500hp with the ac units the others are more specialized for specific areas (coal mines in heavy grade territory) their was an issue early on with the ac engines in the lead with a conventional in the trail as they could overwhelm the dc motors. That has been fixed for a long time, but for a while dc had to lead in a mixed consist. . 2 1 Link to comment Share on other sites More sharing options...
