oldmanrookie,
actually the idea of home anodizing came up at the lunch table one day (you can tell i work at an engineering company). a few of the ChemEng's told the Rest of Us that you could actually anodize aluminum with common household equipment. which surprised me, and hence got me all interested to see what it would take. yeah, ok, i have a propeller on my head too. a few minutes of google-ing and i found the link above. the process and equipment in the link is used by a guy that makes aftermarket focusing pedastals for small telescopes. in other words you can buy the focusers he makes to improve tracking stability or otherwise add focus tracking features to your stock telescope. we're talking 4-10" schmidt-cassegrains here, the US$500 to US$2500 variety.
anyway i was quite impressed with what this guy is doing in his basement -- obviously he is quite proud of his setup and it probably saves him loads of money compared to getting the anodizing done "outside". plus, he can customize the process and colors at will. e.g., if you want a purple focuser he could make one in a few hours. i've been meaning to send him some email and ask if he'll do small jobs.
