That's a huge gear!
Machining A Massive 10-Ton Bevel Gear

In Metal Gear Solid news, this is a video from the fun-loving Finnish couple of Beyond The Press at a factory to see how a 10-ton bevel gear is machined. How are they machined? Very slowly, and it takes about two weeks to finish one gear. For reference, if I was in charge I would be cranking out at least six of those gears a day, all of which would quickly fail and cause the machines they’re in to explode because of all the corners I cut making them. And just what sort of machine even uses such big gears? “One to transport my penis.” Don’t you steal my lines! I’m the one with the totally insane penis here.
