Please tell me if this crank looks OK

OMG, I just realised how old I am - I read that as 0.005 inches (five thou') and thought, my god I hope he means 0.0005 inches (half a thou'), then I re-read your post!

0.005mm is two tenths of a thou' so that's good.

Thank you for assuring me the crank is straight enough. It was sent to Norway just with padding, no one knows how many times it might have been dropped on a concrete floor...

I really can not relate to inches, so I need to calculate the other way to mm's! So, when do you stop using fractions and start using thou?

I often annoy my younger colleagues because I'll refer to something as quarter-inch, then when I see that puzzled expression, I remember to say 6mm, or, if I'm being accurate, 6.35mm.

A crankshaft run-out of two-tenths is pretty good but to be absolutely certain I'd check No.2 & No.4 mains as well, supported on No.1 & No.5. That's what I'd do, but then I rev my Stag engine to 6,500rpm sometimes....
