There are two ways to case-harden steel.
Neither way involves induction heating.
Contact me off-list if you want any more information than that.

Watch how you heat treat your spacer. Do not heat treat it all the =
way
through as it will be brittle and break. Try to get it case hardened =
it
instead Hardened on the outside but still malleable internally. =
Heating
and quenching with an induction coil would be ideal for a part like =
this.
FYI, I have seen these for sale on someone's website, but I don't =
remember
who. Any one else seen these?
