I need a piece of 1/4" hardened drill rod about 33" long but I have no great

Anybody know a source? It doesn't have to be ground or of any precision at
all, just a nominal 1/4".

It occurs to me that air-hardened material may be a possibility but I am not
clear on how this is done.

How hard does it have to be? Would 1/4" music wire do?
