Randy Winberg who makes some of the best crankshafts in the world, told me it did not matter how a crankshaft was stored. That is good enough for me. If the crank was for NASA, I'm sure it would "matter". That is unless you were thinking like using it 100 years in the future.

This topic totally went off topic. Well back to the topic. So, either standing the crank up or lying down is ok then. yes..................... What, talking about wood case Model T batteries is out of bounds in this group?
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Back in the day I used to be a crank-grinder and straightener... If you store the cranks sideways, 'on a rack' then its a real bummer getting to the bottom ones... But I remember my engineering master at school telling me the 'five-ninths' rule! If you have a metal bar of say NINE feet long, then the two supporting places should be TWO feet in from each end leaving FIVE ninth's in the centre... So if you are laying a crank on its side the supports should not be the large outer counter balancers, but the next ones in...

Did you look at the picture in the link of the hundreds of new crankshafts in the metal racks laying helter-skelter? And they were stacked 6 to 8 deep. Lots of weight on the lower ones with no particular pattern of position. That manufacturer is certainly not following your 'rule'.
Master, again and still

If you go to the link mentioned, ( https://phantombullet.net/threads/never-lay-a-crank-shaft-on-its-side.5367/) (first picture on page two), one of the repliers showed a pic of factory storage of finished cranks and said the factory doesn't adhere to the BS about not storing cranks us-supported. If you look closely, he is mistaken, the cranks ARE supported properly, i.e. supports under the second main from each end and nesting slots for the balance throws. Joe

Oh yea" good ole Statics&Strength Of Materials. But sectional dimensions come into play. But a good practice for storing many types materials.

As the senior metallurgist for over 30 years, I must say this is the biggest pile of crap I heard in the past decade! Thank you. I find this very annoying.

Crankshafts are not 9 feet long and I agree this has got to be one of the most ignorant adult topics and ranks with the flat earth crap.
Im sure someone will toss in a large marine type crank as an example but this is a car site and we deal with automotive crankshafts.
Whens the last time we got a storage instruction sheet with a new crankshaft?
STOP POTATO HATE!

Cranks take up less room at my shop when they are on end, and yes, occasionally they get hit and fall over like domino's! A wise sailor once said: "You rolls your dice, you takes your chances"...LOL

A wise sailor once said: "You rolls your dice, you takes your chances"...LOL That is where I am at too. I would lay them down so they don't get knocked over but I just don't have the room. On Crankshafts that have crank sensor tone rings that can be easily damaged, I bolt them to a flywheel to prevent them from falling over. Any automotive crank that would flex enough to be damaged when laying or standing would be worthless in an engine anyway.
