ive done some titanium with heat and electricity both are super simple, aluminum is a bit more difficult and requires more. start with scrap aluminum, you need a 6-12v battery charger, a gallon or 2 of battery acid, dyes, aluminum wire etc. you can cobble together a kit for around $50 if you build your own and shop smart. i stick to titanium only as its cheap and easier. aluminum also puts off some wicked fumes. do your homework and either buy a kit or build your own.

If I buy a top notch kit will I see a super finish like from a professional? Money isnt the issue but how it comes out is.

I have been tinkering with Ti. Since I got the equipment I started a 3rd job so I don't have much free time now.

 I tried  anodizing and parkerizing with kits form different vendors,never really could get a professional look or even decent and getting rid of the waste is all haz mat fees expensive,gave up and took the parts to the shop in Oroville and they made them look like I did not do it,Pm if you want the name of the shop they do awesome work real quality and they have a pick route.there is a lot more to than the instructions in a kit,the good guys have ton of knowledge and skill in finishing metals properly

You can get good results with kits, or a home built setup. It just takes a shit load of practice to get it right. Darker the color harder it is. It's really about if you want to spend the time to figure it out, I got fed up with aluminum, but a buddy of mine can literally get perfect results out of a small rubber maid tub and a damn turkey fryer with his home built setup. As I said before titanium is much easier and simpler so I stick with it only

I agree in general with the comments. However, no one mentioned the chemicals used (acids), or the voltage use (up to 300 VDC), or the emanation of gasses from the process (hydrogen and oxygen). One has to be careful, doesn't one?

Maybe you just can't read? And 6-20v is all most will ever use for aluminum. I clearly mentioned wicked fumes, sulfuric acid and the like.

I can't speak for today, but when I looked into this about 40 years ago for American Radio, most aluminum anodizers were using 90 volts DC, at 25 amps or so. That level of eletro-magnetic force can easily kill. The bath was high-mole sulfuric acid, the same stuff in car batteries. Even the cabinet builder we used, didn't do the anodizing himself.

I anodize everyday at work. It's a little different because I anodize reel to reel aluminum wire (not batch). Although, batch is much easier.

H2So4 10%/15% standard battery acid and distilled water. Room temp puts a larger anodized thickness while higher temperatures are typically less. Yet, the hotter the electrolyte the more conductive it is.

There's tricks to increasing anodized thickness such as adding aluminum sulfate to your electrolyte. I am by far no expert.

Pigments or dyes are typically the hardest to get a hold of in small quantities. Water based ink pen dyes are used (dry-mixed in water).

Like everyone else. Unless you have done your homework, and take every precaution to be safe I would not recommend doing it at home. Clean up, removal, proper PPE is essential.

The fumes coming off (stinky stuff) is not nearly as bad as the H2 you generate during the process. Extremely explosive.

Process goes like this:
Anodize
Rinse
Dye
Seal

Last  time I tried it in my old micro backyard,neighbor asked what the heck is that smell,told I was eating year old Easter eggs and drinkin generic skunk beer :o :o the smell seem to linger a tad bit pretty potent, so beware where you try it,nowadays may get some unwanted attention from a haz mat team,too much time required,too smelly and getting rid of spent stuff is a huge PIA my time and health is worth more
