What is it?

This is my mystery steel. I'm hoping that someone can tell me what it is and where it was used. I believe it's high carbon and I would like to make some drifts from it, if possible.

 

It was threaded on one end with a keyway and geared on the other.[

Looks like something off of an old cotton picker.  On the other hand, its probably from the Roswell crash site.  :ph34r:

It appears to be axle stock.  4140 is a good guess.  That's not high carbon... but it makes pretty good drifts for most purposes.

I would agree it looks like the innards of an axle, possibly from an alien space craft, but not sure on that. 

The circus used to come to town and they used those as "tent pegs", drove them in with big sledge hammers, used the elephants to pull them out.

Looks like the driveshaft for the chamber packing fingers on an international small square hay baler. the tapered keyway would fit a 45 degree timed bevel gear the 90 degree gear end is driven from the plunger crankshaft.

I've seen them used a tent pegs for large tents too; so probably something that was common some time ago.  While we would use  4140 it may have been a straight carbon steel "back then"...

 

High Carbon can be detected by the spark test; especially comparing with a good file.  Medium carbon is a bit harter to judge without a lot of known samples

it is an axle off of some  type machine. when i was a kid we used them all the time to stake out critters on a chain. chain had a big loop on one end and the axle was slide through it then driven into ground with sledge hammer. nothing ever pulled them out.
