|Anyone remove the anodized color off a wheelset?||Fashion Faux Pas|
Jan 10, 2002 1:47 PM
You probably guessed it... i got a set of bright red heliums, but I got a different frame and color so the bright red wheels don't match at all.
I'd sell the Heliums, but I figure I won't get much for them and I'd be better off keeping them.
So... has anyone successfully remove the red anodized color off their wheels?

|assuming that your question is how- oven cleaner|

|Oven cleaner removes anadozation from aluminum? I seriously doubt it.|

|There are 2 ways to accomplish the removal depending on the surface you want to end up with. A NaOH etch solution will remove the coating but will etch the surface leaving a diffuse (matte) appearance. A chromic acid/phosphoric acid solution will remove the anodizing without affecting the underlying surface. The composition of that bath is 80 grams of chromic acid in 3.5 liters of water, add 140 ml of 85% phosphoric acid, add water to make 4 liters. The bath is operated at 190 - 200 deg. F. Immerse the part for 15 minutes and then rinse well in water.|

|he could find someone who uses bath anodizing and have them stripped or redone in another color-- humor has it's place but answering the question in a way that helps is probably better-- jason h told him it could be done and in a simple way-- if that's what he wants to do he now knows it can be done--|
Jan 10, 2002 6:38 PM
|For all of Jason's specific, good, and well intentioned advice he neglected to mention anything about what one does with the hazardous waste or that it's against Federal law to use a chemical product in a manner in which it was not designed or labeled (says so right on the can). Ultimately the whole idea of actually changing the color of your rims is totally ludicrous. Surely you must see that? Sorry for calling you Surely.....;-) |
Given that this is just a bunch of mental masturbation what do you care if stuff gets all over the place if you don't have to clean it up?
Jan 10, 2002 6:48 PM
|you really seem to look at things the way you want to see them-- the question was if it could be done-- jason h gave him the technical way of doing it-- i don't see anywhere in jason h's post where he said to do it yourself-- that's what your seeing and mentally masturbating over-- but then this reply will probably get lost in that myopic vision of yours...peace|

|Well, gosh, I guess it's possible to build a spaceship in my backyard also. It *is* possible and I'm sure there's more than enough solid advice here on the net on how to do it. Any advice out there? Please - positive and serious responses only. This is serious business adn I'm serious. |
Fact of the matter the whole thing is hypotheitcal - sorry about the reality check of having to deal with the waste - I'll try to refrain from being flip and realistic and any mention of the law. There isn't any way the guy is actually going to do any of this and if he were to try there are a bunch of real world obstacles to address, like etch depth, maintaining the machined braking surfaces, dealing with the rest of the assembly and the eyelets. In the end he'd throw the wheels away, which may be a good solution since he could get the right color when he buys a new set. I assume you've actually dealt with refinishing aluminum and actually taken things to a shop to get them anodized. If not maybe *you* should refrain from commenting. This assumes of course that you have experience building wheels and enough of a technical background to think through the entire process from start to finish. Where is it written that we have to be foolishly optimistic on every response? Someone told me that the word "naive" isn't in the dictionary - and I believe them.
I thought your big complaint was that you didn't think I was funny and that I should be more constructive in answering the original poster's question. How's this: It would be foolish to try and change the anaodized color of a set of built wheels for reasons that we shouldn't discuss since it's not a positive statement.
Geez - who put your knickers in a twist? And hey, wipe that smirk off your face - I gots X-ray vision.
Jan 11, 2002 2:53 PM
|well at least some of your sight is coming back-- how about..it would be foolish to strip the anodizing off your wheels and here is why. then he would have the knowledge, from jason h, that someone could do it for him and the reasons you think it's not a good idea-- that way we have empowered him to make his own decision-- if naïve it is a lesson he will learn and benefit from-- sometimes a question that is naïve to you may not be to someone else-- |
btw..there is a line between ridicule and humor that sometimes we don't see or each sees differently--
oh and i have had anodizing work done and i don't wear knickers and your ex-ray vision isn't working very well and if you wish to build a spaceship in your backyard more power to you...*S*

|I was just giving the details of how it was done. There wasn't a recommendation to do it himself anywhere in there. Sorry if giving too much information confused you grz.|

|Aluminum is an amphoteric metal. That means it can react with acids or bases, and so you can't use it to store either. NaOH is a strong base, and so attacks Al - if the oven cleaner uses NaOH as the active ingredient (many do) it will attack the anodization. However, you run the risk of an un-even etch and some thinning of the Al where there are scratches or you have already worn off the anodization. It would be best to do this carefully by applying the oven cleaner with a rag rather than spraying it on - and make sure that you wear gloves!|

|....and don't forget to use a q-tip around the eyelets. |
What price fashion?

|Anodizing is not like paint. It's actualy and electro chemical process involving a transformation of the aluminum near the surface. You could etch or grind away the material near the surface, but I don't think this is what you had in mind - nor would I advise it. Try to forget the whole color/fashion statement issue - sell the wheels if you can't be seen in public with them.|
|how about painting over? (why not!)||tempete|

|Not the braking surface I mean!||tempete|

|Get them re-anodized?||tarwheel|
Jan 10, 2002 2:46 PM
|Seems like you could take the wheels to someone place that does anodizing and have them redone in a different color -- preferably black or dark grey. If you re-anodized them blue, they would probably end up being purple. But this is pure speculation on my part as I know nothing about this ...|
|Get them re-anodized?||grzy|
Jan 10, 2002 4:53 PM
|So would one remove all of the hardware and just have the aluminum rims or would you somehow leave the spokes, nipples eyelets and hubs in place? Then there's the whole concept of having the braking surface anadozed as well. Another consideration - ever priced getting something anodized? The EPA has made it a lot tougher and much more expensive - which is mostly a good thing. Many shops are shutting down as a result. |
I see this as an interesting technical question but it's the result of a fashion statement. Whatever happened to being seen riding on Heliums as a good thing?
|Anodized eyelets||Kerry Irons|
Jan 10, 2002 5:15 PM
|The eyelets are brass, and I bet they wouldn't come out looking quite like the rims! I don't want to take the time to look up the electronegativities of everything, but you could run the risk of dissolving the eyelets as you re-anodized the aluminum. As you said - what price fashion?|
Jan 10, 2002 6:27 PM
|You can be sure that the guy who owns the anodizing tank isn't going to be happy with anything going into his tank that isn't aluminum and could contaminate his solution. |
I was kinda thinking that the eyelets were something other than brass - more like stainless - since the nipples are either brass or aluminum. You'd want something that is tougher than the rim material and the nipple - otherwise what's the point? The eyelet won't effectively distribute the load and a worn out eyelet is a lot harder to replace than a wornout nipple. Anyone know for sure?

Do yourself a favor and don't trade a fashion faux pas for a technical blunder.
I'd ride 'em personally. Who gives a fook about fashion anyway? Then again I'd never by red wheels so I guess I do!
Cheers to parts in silver and black! Save the color for the frame.

|Use a magic marker and change them to dark bronze anodized finish (kind of).
It's an old trick used by Storefront Contractors to hide scratches on a dark bronze andodized finish entry.

|You could look up the voltage potentials required to anodize the blasted things with whatever solvated ceramic was used to create that specific color (Campy may be able to reference it for you, or direct you to whoever did it for them) and compare it to the voltage potential for ionizing aluminum. If a smaller absolute voltage is required for the anodizing ceramic than it would be possible to deanodize without dissolving away the rim itself. Of course, assuming the voltages are so convenient, you'd have to go through the trouble of learning how to do it (actually, it's not that hard), as well as getting all the solutions, etc., and as grzy says it could be a pain in the arse to dispose of.
Honestly, if it's really that important to you, I would tape everything up and paint the rims black; it'd be mildly tedious to tape, but once you do you can just spin the wheel and spray.

|Fer Chrissakes. I remember when people liked the Heliums because they stood out. Why do the wheels HAVE to match the bike? Just use them as they are -- I bet you'll never notice they don't match when you're out riding.|
