Best anodizing guide?

[JOGARA]

You don't need to heat the acid bath really, in fact in general the colder it is the better the result.

I often see other stages using an aquarium heater or other similar submersible heating element. This would certainly get things warmed up quickly enough!

From what I read you don't want the acid hot at all. Both the etch and/or the anodizing tanks should be room temp as those processes get hot when reacting/putting amps though them.
The Desmut, Colour and Seal should be heated though...


Going off the Ron Newman guide that m_c sent be lists this;

1. Polish part using fine sand paper for shiny finish, or wire wool for matte (can also etch for a little longer for matte finish/hide imperfections)
2. Cleaner @ 140F 5 mins
3. Rinse (de-ionized water)
4. Etch in Lye for 10-30 seconds @ room temp
5. Rinse (de-ionized water)
6. Desmut @ room temp 1-3mins
7. Rinse (de-ionized water)
8. Anodize at room temp based off 720 rule
9. Rinse (de-ionized water)
10. Dye @ 140F for 15s-15m
11. Rinse (de-ionized water)
12. Seal @ 180F
13. Rinse (de-ionized water)
14. Hang to dry for 24 hours
    

Other guides I have seen do mostly the same procedure, though one suggested using "Sodium Bisulfate/Sodium Hydrogen Sulfate" instead of Sulfuric which I guess is safer?

As for heating the buckets, I like the one you linked, but I am limited on power in my current workshop. Wont be in my new one till end of November.
Pretty much can't draw more than 3000w in total.

Thinking of getting a couple 12v ones that I can then use one of these cheap controller boxes with. Safer too as those immersion ones don't always have earth on the metal case.
