Default How can I blacken stainless steel spokes?

Nowadays with all the spoke options I am hard-pressed to keep, or
indeed, find stock of all the permutations. How do they blacken spokes
and can this be done in a workshop as and when needed?

Get a tool to cut&roll your own?

Not in any durable way that would compare to the manufacturer.

black anodized steel is a common thing, all you have to do is find out how
it is done and do it on a small scale for spokes.
hope this helps

Can't you just heat them up and dunk them in motor oil. I seem to
recall that from boyhood buggerings about.

I'm pretty sure that anodizing isn't used on steel.

"Anodic films are most commonly applied to protect aluminium alloys,
although processes also exist for titanium, zinc, magnesium, and niobium.
This process is not a useful treatment for iron or carbon steel because
these metals exfoliate when oxidized; i.e. the iron oxide (also known as
rust) flakes off, constantly exposing the underlying metal to corrosion."

http://en.wikipedia.org/wiki/Anodize

I wonder how stainless parts are made black, commercially... some Googling
turned up:

"...there is a commercial proprietary product available for blackening
stainless steel based on copper-selenium chemistry. It is used at room
temperature. More information can be obtained by doing an internet search
under the term “blackening process.”

Wouldn't blackened spokes be even harder for squirrels to see?
