New adventure: anodizing aluminum.

New adventure: anodizing aluminum. I'm using some Zep product for etching because it says it is all lye. That's a filthy lye: it leaves blue junk on the aluminum. Don't use this. @MLE_online told me to get Red Devil and I wish I had. I'm using sparex #2 (NaHSO4) for sulfation, 25V for 30 min, aluminum cathode, anode, clamp. Pic of it sulfating and right out of the bath.

After anodizing it goes in the dye. I'm using somewhat dilute RIT at 80C.

And then it gets boiled to seal the dye in and put to use. This is a stem compression cap for aheadset style bearings.
