I got a fluted seatpost for my Le Tour III in the impossible-to-find (anything cool) size of 25.8 and I want to shine it up all shiny. It's got that machining texture to it so I'm hoping I can get pay someone else to do it. Problem is here in LA all the machine shop sort of places are clustered pretty far away from me, so I was wondering if there's anywhere else I might try taking it.

For instance- maybe a jeweler could do it. Or maybe... I dunno, I'm just wondering if some type of business does this sort of thing and I'm just not aware of it. Like one of you might say "yeah, bagel makers usually have a polishing machine, ask one of them" except not as ridiculous.
