Cold forming steel

[darkbeaver]

Cold forming sprocket teeth in a die at 12 tons, no two alike, help.

you need to jam all those square pegs into a round hole to enforce conformity
those little children will all learn to be alike
...and they will do it well...that's what makes 'em different


also one might expect global warming to help with the cold that's forming
