Real Mystery metal - Sunset Machine - 03-10-2016 We've probably all seen defects in metal but this takes the cake. It's a bar of mystery metal that I was making a temporary arbor with. As I was approaching final size, a crack appeared. It got bigger and bigger until the part dropped off. And when I looked, it was flame cut. Inside the bar! RE: Real Mystery metal - awemawson - 03-10-2016 Originally two parts welded together - probably Vee'd out to increase weld penetration - and you've now turned down to smaller than the penetration of the weld. RE: Real Mystery metal - Sunset Machine - 03-10-2016 Bingo! They must've turned off the weld and stored it in the mud where I found it years later, looking like a solid but rusty bar. Not such a mystery after all then. RE: Real Mystery metal - Roadracer_Al - 03-10-2016 You're a lucky man! What are the odds of finding that weld? Actually, that reminds me a little of this: http://www.instructables.com/id/Pre-sliced-Banana-Prank/ RE: Real Mystery metal - Sunset Machine - 03-11-2016 That's what I was thinking. Another 1/8" shorter, I'd have called it good and presented it to an expensive cutter - snap, crackle, pop as the end ripped off. |
