The Jaigarh Fort and its cannon ...

[fernando]

On the Dardanelles cannon Michael Kritoboulus, a Greek dude that wrote the history of the Ottoman conquest of the Eastern Roman Empire under Sultan Mehmet II, describes the (some) foundry details of the cannon but kept silence on the technique used to cast the screw parts.
All we know is that its threads were sharp and clean as they were on the day they left the foundry and, according to naval officers who unscrewed the breech in 1868, it took a total power of 40 tons of jacks and man power to dismantle it.
Although we ignore what tools the Turks used for the operation, providing this ever took place, it is evident that the means used to unscrew it in 1868 were not properly a set of pipe wrenches. Also my theory on the gasses escape meets no case.
