Anodizing
DeereGuy:
Almost forgot to post the pic I promised.
This is a (Clairiant) Sanodal Deep Black MLW...if you start with a nicely polished reflective finish you can get a nice wet looking black from it. This part was
The part is 55.9 sq inches. I wanted to be as close to 15 ASF as possible so I set the PS at 5.8 amps and set my timer for 48 minutes. The ano tank temp was 80 degress. It spent 20 minutes in the dye and 20 minutes in the sealer.
I will probably stick with 12 ASF and tank temp at 75 degrees for an hour...

So the power supply should be adjustable? I have a couple of 12v power supplies here. on is 5amp the other is much higher... will have to check.

DeereGuy:
Depends on how serious you are about doing this. I did get some rit dyes to take with a computer power supply, laptop powersupply, 12 volt car battery charger....
The samples are sitting on my self. The finish is soft...color fades....blotchy...but hey they did take dye. I don't think you are going to want to put the parts on your bike..
Sorekiwi:
I tried it a few years ago, and have meant to do some more, but other projects kinda got in the way.
Mine was a very low tech set-up, an automotive battery charger, RIT fabric dye from the supermarket, and Lye drain cleaner. For acid I used new automotive battery acid (for those of us stateside, you can (or at least could then) buy a gallon container of it from NAPA).
I fpretty much followed the instructions from Chris Heapy's website (an archived copy here: http://nsa.kpu-m.ac.jp/gijutu/kousaku/easyweb.easynet.co.uk/chrish/t-anodis.htm) :offtopic: but some other awesome info there.
I never got the bits I wanted black to come out very well, apparently thats a common problem with fabric type dyes. Here's a pic of probably my best result, this is RIT dye and everything red I did came out well. This is a mandrel for installing a caged needle roller bearing:
DeereGuy:
That looks very good. I did have a few successful runs wih rit dye and non adjustable supplys. Unfortunately it was after stripping the same part several times and getting lucky with the second or third try.
