    Nice!

    What current and voltage did you use?

    I think home anodizing is on almost every laser and cnc-tinkerers to-do list!

    Great Job, Thank you for all of the pictures! I am tempted to give it a try, I was about to setup a small electroforming bench for copper, adding in anodizing doesn't seem too much harder.

    Edit: After a little thought, it would be easier and cheaper to send it to you once you get things going!

    Laser (the acronym derived from Light Amplification by Stimulated Emissions of Radiation) is a spectacular manifestation of this process. It is a source which emits a kind of light of unrivaled purity and intensity not found in any of the previously known sources of radiation. - Lasers & Non-Linear Optics, B.B. Laud.

    Hey Adam -

    Couldn't say it better myself, so, yeah, exactly what Andy said! ...Will def be in touch...

    Listen - we recently cleaned-house at Laser Images, cause of the offices-move (scaled the machine shop waay down - sad, sad day... and I found a bunch of chemicals, I presume were used in metal-prep, etc - several gallons of "Aqua Ammonia", used for acid neutralization, yes? A jar of pure Zinc powder - (yikes!) a bottle of sulfuric acid, couple bottles of blueing, and cleaner, and a small bottle of sodium hydrox...

    I know I can't ship any of this to ya, but rather than just give it to some chemical co. to dispose of, if we can figure out some logical way to get it to you (we might have a gig up your way later this year; waiting on confirmation...) you want the stuff? free to a good home...

    lemme know - no biggie, either way...
    peace..

    Cool. Is there some kind of publicly available procedure you followed?

    That looks very nice! I was under the impression that anodizing was tricky and messy, but that looks very simple and clean. What acid and concentration did you use?

    Congrats, Evil Adam! The end result looks perfect! I have a feeling you just opened the floodgates to a little side business for yourself...

    Looks great!!

    I have to pick up some stuff from the anodizer tomorrow. $65 setup charge and about .25c per part. Week and a half wait...

    I might have to give this a go myself.

    Thanks for pushing me over the hill, Pat. I'm glad I did it for myself. I love learning new things.

    Thanks! I'll let you know when I'm all set up.

    Thanks! Yeah, I know a lot of people would like to have their small parts anodized.

    Thanks for sharing the method you used and the great pics..

    Thanks! I just read a whole bunch and summarized on what steps I should take.

    Thanks! I'll put you on the list!

    Yeah, It's funny because I had everything in my lab to do it except aluminum hanging wire. I actually used RIT clothing dye and it worked great. I'm still considering switching to an industrial dye and nickel acetate sealer but if this is what I can expect from clothing dye,,, It Rocks!

    I had thought of trying it; my work schedule thought otherwise.
    Thanks! It's actually pretty easy. Hard to mess up in my opinion. Only thing I don't like about it is the caustics and acids.

    I used a variable lab supply in order to play with voltage and current. For this piece I tried keeping the current between 1.5 and 2A With a voltage of 12V starting and finishing around 18V. The anodizing layer actually becomes an insulator as it forms which requires a little more voltage to keep the current consistent.

    Thanks! I'd highly recomment anyone who wants to give this a try to just do it! It was easy for me since I had all the chemicals and tools here but a little investment is well worth the experiment.

    Hey Jon! Chemistry is also one of my hobbies. I'd be glad to take those chems off your hands if you happen to be in town and it works out for you. I'll also put you on the list of anodizing seekers.
    Thanks!

    Yeah, Here are a few of the good links I studied...

    http://www.focuser.com/anodize.html

    http://coloured.net/designresources/anodize.html

    http://www.thefintels.com/aer/homealuminumanodizing.htm

    I just gathered info from all three sites and went from there.
