How to remove anodizing (rims/cranks) / Polishing aul. to mirror finish.
To be honest it has been at least 25 years since I have removed anodizing from aluminum, so the details are a little fuzzy. I did a quick web search on oven cleaner anodizing removal and found this thread in a different formum: http://www.finishing.com/2000-2199/2076.shtml It has a few good pointers, and a couple of different ideas about chemical removal of anodizing. I had good luck witht the oven cleaner, and polished the aluminum to a mirror finish. Apparently it was really luck more than anything. The posts in that form lead me to believe that getting a good finish with oven cleaner is very difficult. -- jtrops ------------------------------------------------------------------------ jtrops's Profile: http://www.unicyclist.com/profile/17262 View this thread: http://www.unicyclist.com/thread/75399 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

How to remove anodizing (rims/cranks) / Polishing aul. to mirror finish.
Thanks a bunch. Sounds dodgy to me. I might give it a try, or just have it done some place. I don't want an ugly rim now. -- wickedbob R.I.P MITCH HEDBERG 'Add wickedbob to your ignore list' (http://tinyurl.com/3dfrko). Help to keep JC all Billy, all the time.

How to remove anodizing (rims/cranks) / Polishing aul. to mirror finish.
I am thinking of doing my K1 cranks with oven cleaner, but I have one question: Will de-anodizing remove enough material to make the crank loose on the hub? I don't think it will but i just want to make sure before I start. I don't think a clear coat will be needed, as the cranks have a raw logo on them, and being on the cranks, it would just rub off anyway.

How to remove anodizing (rims/cranks) / Polishing aul. to mirror finish.
Again it has been a long time since I have done it so keep that in mind. I removed the anodizing from a pair of Sugino Maxi Cross cranks once and they never had a problem with fitting tight on the spindle. It didn't really seem as if metal was coming off of the cranks, just the color. If you've got some old aluminum part laying around you should probably try it before you commit your nice stuff to it.

Anodising is only a few thou(sandths of an inch) thick, so if you remove only what is necessary, and where it's necessary (not the splines) you shouldn't have problems with the crank loosening. -- madmattunipro Unicycle For Christ www.bedfordunicycles.ca http://www.norco.com ------------------------------------------------------------------------ madmattunipro's Profile: http://www.unicyclist.com/profile/10763 View this thread: http://www.unicyclist.com/thread/75399 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Thanks for the tips guys, I'm going to buy some oven cleaner today or tomorrow, so I will see how it all works out and hopefully post up some pics.

How to remove anodizing (rims/cranks) / Polishing aul. to mirror finish.
Alright so I de-anodised my cranks and seatclamp today. Here are some pics: Before [image: http://i462.photobucket.com/albums/q...MGP0202-1.jpg] After [image: http://i462.photobucket.com/albums/q.../IMGP0297.jpg] [image: http://i462.photobucket.com/albums/q.../IMGP0298.jpg] The process was fairly simple, I just placed all the parts in the caustic soda, then after about 10 minutes took them all out and rinced them. (Some of the anodising needed a bit of a scrub with scotchbrite in parts.) Then, I polished them up a bit in the tricky spots with the buffer bit on my dremel. I gave up halfway through polishing the cranks because it was getting dark and I'm lazy... I think it looks way better than it did before and I am going to get rid of all the red in time..
