How does a cast iron (non nodular) crankshaft fail
Just was wondering has anyone on here every snapped or know of someone who has snapped a cast iron non nodular crankshaft before? And how did you/they do it (i.e. speed parts, abusive driving, racing, etc...) and if it was an instantaneous action or a progressively long draw out process.
I'm am not trying to compare the nodular and non nodular crank since we all know which one is stronger. I just want to know at what point was the breaking point for this supposed weak crankshaft. And no shame, be as humorous as need be!

I had one a couple of years ago that I suspected was cracked but could never find it.
I replaced it with an N crank. When I took the cast one to the junk yard it broke in two when I threw it on a pile. Go figure.

Wow, that is bad, broke in half. Unless you have been practicing your caber toss, I bet it didn't even fly that far. Was it a BBO or SBO crank?
