I recently bought some titanium rings from Rio Grande with the
idea if altering the surface just for fun. The edges and inside of
these rings are super shiny. I have never managed to get a polish
like this on titanium. Can anyone tell me how this is acheived?
The rings from Rio are more than likely mass finished with some
super secret squirrle process that envolves equipment that hasnt even
been developed yet. ;-).
But, to answer your question, lots of surface prep. Ive gotten away
with sanding down to about 400/600 (or ruberized abrasive). From
there I use a bobbing compound to smooth everything out, then a white
rouge for a final polish, both on a stiched yellow buff.
Im not sure what grade Ti you are using, but this works well with
6al4v titanium. I suspect CP titanium might be a bit more difficult
to get a super high polish.
What ever you do, do NOT use a grey deburring wheel on titanium, it
tends to smear the surface. The real trick with finishing titanium
by hand is sharp abrasives and lots of compound. Also plan on
spending more time on the buff than you think you have to.
