DISAPPOINTED!!!
Should be "Does anyone know how to anodize?"
A little thought about the title goes a long way.

By the way, I'm sure Google is your friend on this one. Yep. It is.

useless post? I think so, if your going to make a post about how you see fit to title a thread then dont post at all. A simple PM pointing out the lack of proper thread "Etiquette" would of sufficed.. but whatever..

How about posting an actual link, or some information about it rather then saying "Google is your friend"..


anyone actually have anything to contribute to this thread?

\/ I was actually trying to find an article on how to do it, im interested in trying to do it myself :). But it appears every article i find wants me to pay to read it.. Ill call a powder coater at the last resort, if i can learn to do it myself that would be bitchin :)

I know how. Been doing it for years. I can even do Type III. Not hard once you learn the techniques and invest in the gear. That said Google *is* your friend. Why would you risk getting misinformation about any subject (a common problem with all forums) when you could so easily get the facts?

Jetjock i agree google is my friend but for some reason the word anodize & How To on google gave me a bunch of places to buy the manuals. can you just run through the basic concept on how it works?

Here's a more important question. Can you anodize stuff for other people, and if so how much?

Well IIRC chroming is pretty simple, just pass current through a tub full of chrome liquid and ground out the metal item. Correct?

Just curious on how anodizing works

Skip the how to part and just try anodizing or anodising. I'm afraid eletroplating (chrome or not) is a bit more complicated than what you're suggesting but yes, those are the very basics. And no, I don't do parts for others. I'm set up only for very small pieces. Anodizing gear takes up a lot of room and chemicals once you get into doing bigger stuff.

Thread title changed. :)

It's not very complex to do, but it does require some rather nasty acids that most people would not want to have floating around the house. Further, most home setups can't get anywhere near the quality that a real anodizing shop can.

JJ is likely the exception that proves the rule, of course.

I'm pretty interested in trying this after reading supra90turbo's link. The chemicals aren't that hard to get (especially since they aren't meth lab chemicals for once), and I've worked with concentrated sulfuric acid for years so I'm not too afraid to give this a go. A couple of questions, though: Since anodizing is limited to aluminum only and small parts at that, what parts have typically been done for your cars? Jetjock - how large of a piece have you been able to do with your home set up?

I dunno how much of an exception I am Grim but as with anything the right gear, study, and practice helps. Understanding the fundementals also goes a long way. Anodizing is basically just dying the oxide layer. That said, I trashed my fair share of parts while learning and still mess up a few on ocassion.

Unless one has a lot of stuff to do or is willing to accept the learning curve I'd recommed taking parts to a shop. I you want to try there are lots of online places that'll sell you everything you need for doing it at home. Start small and work you're way up. That way the expense is less as you learn.

LouKY: I can't do anything bigger than about a two C cell flashlight. In fact it's one reason I got into anodizing. One of my hobbies used to be designing and building high tech custom lighting tools. I also use it for other reasons as anodizing has many applications besides decorative. The fitting of small parts and to provide electrical insulation for example.

Have fun but be careful. As Grim mentioned, there are some corrosives involved.
Home anodizing is actually a fairly popular and enjoyable hobby and once you get it down you can even make some coin with it. Get too big of a system though and your local city eco-types will come knocking.

If DYI plating is your interest there are also places that'll help you out. Many people run small businesses that gold plate car badges for example. For small jobs try a plating pen like Hunter Products makes: http://tinyurl.com/kajxp

Otherwise I'd avoid getting into plating because it's far nastier, epsecially chrome and gold. For example you normally have to use a cyanide solution to plate gold. Course, I'mtalking about plating here, not anodizing. As Duane mentioned, "hard" (type III) anodizing is best but trickier to get right and last time I checked the range of colors available was far less than type II.

i've done a bit. The more attentive you are to detail and control the more successfull you will be at it, because some processes can get pretty finnicky. Anybody just wanting to do a few pieces would be much better off to have somebody else do it though...setup costs can get just a little bit pricy.
