why don't you go with a piece of Thomson shaft, it is already hard and comes
undersize by a couple of thousandths.

Reid Tool carries it so does MSC

It comes in 36" length

Reid part # TLM_1605 $42.48

msc part #56540495 $25.30

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?
