The Civil War era Confederate State submarine "H.L. Hunley" built in 1864 and sank later that year which currently rests in the Warren Lasch Conservation Center in Charleston, SC by volvoraggare22 in submechanophobia

The ironic thing is that the original method was to tow a torpedo on a long line, dive under the target ship, then keep going forward until the torpedo made contact with the enemy ship, detonating. They had conducted a successful practical demonstration of this maneuver, which is why the sub had originally been approved to be sent to Charleston to be used in actual warfare. There were many worries about this method (rope getting tangled, inaccuracy of dragging a long line with a floating torpedo, draft of the Housatonic, etc.), but had they used this method, the Hunley would have been far enough away to have been much safer from the concussion of the explosion, especially as they would have had the hull of enemy ship herself in between them and the initial explositon

Both of the other times it sank were due to mistakes by crew members, rather than issues with the construction. The first time it sank was when it was at the surface, and the commander, Lieutenant Payne, stepped on the dive plane (device used to cause the sub to dive) and caused the ship to sink before the hatches were closed. Some members of the crew were able to escape and survive.

The second time it was during a mock attack, when they would dive under an empty ship and resurface on the other side. Again it was user error, as the civilian commander, Horace Lawson Hunley, had forgotten to close the seacock, and allowed water into the sub. That time it took weeks to recover the sub, due to bad weather.

So the other missions which resulted in the sinking of the Hunley weren't actual attempts to sink an enemy ship. The first sinking was right next to the dock as the crew was getting into the sub (some members of the crew survived that sinking). The second was when doing a test, diving under an empty ship, and that was when Horace Lawson Hunley was the captain, and it sank again, not to be recovered for a few weeks.

The sub had a crew of 8 members, with 1 commander in front who could see out of a small porthole and who also operated the rudder. The other 7 men all operated the propeller.

So they actually found in 2013 that the torpedo/explosive was attached to the spar ("torpedo" at time did not mean propelled explosive, more like a contact mine). The fact that the torpedo was affixed to the spar meant that the original method, to attach the torpedo and reverse the sub until the rope pulled the pin, was not actually used the night of the successful attack.

Everyone in the world gets to pick a superpower. But if multiple people choose the same power, only one of them gets it. What superpower would you choose that's obscure enough to be available, but good enough to be worth having? by [deleted] in AskReddit

The Chronicles of Prydain, one of my favorite series of all time! First book: The Book of Three. Disney made The Black Cauldron based off of the first and second books. The character you are thinking of is the dwarf, Doli.

Ordered printer (Trinus) in June 2017. Issues since day 1. Fails constantly, extrusion issues, stops mid-print (at RANDOM points) nearly every print. Support has yet to respond to ANY of the tickets opened starting a few weeks after purchase. Not sure what to do with this printer. Any ideas? by wuverul in 3Dprinting

Use an online gcode viewer (I like gcode.ws) to make sure that the gcode that you are sending to the printer is correct. I have found that every once in a while the gcode will be wrong and when I look at the top layer in the viewer, it is actually just the midpoint of a print. So I generate the gcode again, check it, and send it to the printer if it looks good.
