Lots of people make cradles out of wood that support the mains. People also commonly stand them on end, but that can go bad if there is nothing to keep them upright.

Standing on end is best!

Secure it to something and stand it on end is the correct way.

stand it up on the flywheel end and wire it to a post or a heavy shelf, if storing for an extended period get a can of spray on chain grease and coat it liberaly to prevent rust from forming on the mains and rod journals

I havnt stored a crank in ages but we use to coat them in heavy grease like litheum, wrap them up air tight and eaither stand it up on end or put it on the shelf.

Come time you need to use it, clean it with spirits and it's just like you pulled it out of an engine 5 minutes ago.

Ok so everyone should know to coat something with grease or some other form of protectant if its something that can rust and they don't want it to rust. With that said under what circumstances will a stored crankshaft warp or have any damage unless some great force, or extreme heat is applied to it. I store my crankshafts, mags, flywheels and blocks all the same way... In random piles, in a dry barn, and they seem to be just fine..... I guess I am missing the point here, can anyone enlighten me?

When I toured the John Deere engine plant at Waterloo, Iowa, in 1987 there were crankshafts and camshafts piled like cordwood all over the place....... .......

We usually store them on end, but they sure hurt when they fall over and land on your toe!!

Is it myth that crankshafts warp?

This doesnt have to be a complicated subject here. If you are storing a crank for a number of years or if you live in an area were you constantly have temp. fluxuation, and no climate control, you need that rust prevention via oil or grease. I dont exactly consider de-rusting cranks, fun.
Any crank or peice of bare metal WILL rust, eventually. If not protected.

so oil it down, store it proper and if it was any count the day you took it out of the engine, then by all means, it will still be good when you uncover it for use.

Ford recomended that Model T cranks be stood on end in storage to prevent warping. New cranks now come in a box and are stored flat. An old timer in our area with many marine engine parts stored all of his cranks hanging by a rope from the first throw, it would have been hard to stand these on end.

It's a myth. They would warp sitting in the tractor with a 175lb flywheel hanging off one end... In the case of the D a 250lb flywheel. However, when it falls over from a standing up position it may warp (bend) from the impact with the ground. The worst thing (as long as they are not dropped) is not protecting the journals from rust as others have stated. One note on rust protection. If there is finger prints or other contaminants on the metal before rust protection is applied you may be in for a surprise later on. The metal must be clean before the protection is applied. The best protection keeps oxygen and H2O from getting to the bare metal. Store it where the temperature doesn't change much. Temp change is the biggest reason for condensation occuring.

im not sure just sitting around would cause a crank to warp, if that was the case an engine would mangle them to bits, we tore a 351 cobra jet ford apart the other day that locked up hard enough it sheared all of the torque converter bolts off the flywheel and after having it checked it was fine. no cracks warps or major stresses

Sitting in an engine, supported by the main bearings is nothing like laying on the floor with all the weight on one counterweight or rod throw...look at the crate a new crank comes in, it has wood cutouts for every main. Machine shop here had a heavy bench w/racks underneath to hang cranks by the rear flange, he would kick your ass if you laid one down... Stand 'em on end, use 1x2's to clear the dowel pins if it has them, tie it to a solid rack or bench...if you have to lay them down, build a cradle to support the mains.
