Someone was asking me about home anodizing so I am reposting my process:
1) Prepare the surface by sanding, cleaning, and sandblasting
2) Etch with a lye solution for a few seconds.
3) Rinse
4) Desmut/deox for 2 minutes (I use Caswell's solution)
5) Rinse
6) Anodize for >=90 minutes using a 2:1 distilled water to battery acid solution. The + lead of the power suply connects to the part, the - lead goes to a lead plate in the tank. Try to keep the solution as cold as possible by doing it on a cold day or using a double ice bath. Aggitate the part often (turn off the power before touching the tank bar so you don't kill yourself).
7) Neutralize the part in a baking soda solution
8) Rinse with distilled water
9) Dye for an hour (I use Caswells anodizing dye). I found that I get better results at 120 to 130 F instead of the suggested 140 F.
10) Rinse
11) Boil in a nickel acetate solution to seal the anodize for about 30 minutes
12) Rinse and apply wd40
