Mirror finish on cast titanium?

+++

In my free time I like to produce titanium jewelry(generally grade 23, 6AL/4V ELI), and have recently been looking into titanium cast components to speed up my creation times... The problem I am having is discerning a finishing method for working with cast titanium. Right now finishing is primarily done with sanding/polishing/buffing... But if I am to switch over to a more complex cast titanium part, I know I will encounter a much harder casting surface outer layer and surface areas that cannot be reached with conventional hand finishing means... So, my question would be, before I spend $600+ US on a casting run, what are my options for producing a smooth surface with a mirror finish in titanium? Keeping in mind that this is hobbyist work, done at home, and although I don't mind working with chemicals, I would like to avoid anything particularly life threatening...

Not sure if it would work for your type of designs but I use a vibratory tumbler on our jewelry (titanium, stainless steel, brass, aluminum etc etc) and it works very well. Mirror polishes are easy and much less time consuming. You will need a "jewelry" type setup not a machine shop setup. Most machine shops just tumble to deburr. Jewelry setups work down to a rouge. The abrasive media lasts years..our setup cost about $500 altogether and other then buying fresh rouge its all lasted for 7+ years, and we tumble on average 2,000 ear rings at a time.
