Best anodizing guide?

[JOGARA]

Just tried one of these in a 500ml glass jar and it worked pretty well.


Took a good 10-15 mins to get up to temperature so would expect a lot longer with 5l tubs.
Runs at 12v and draws pretty much bang on 10A so 120watts.

Going to test wit 5L now!

The specific heat capacity of water is 4.184 joules/gram/deg, so to raise 5 litres of water from 20 to 80 degC, would take 1255200 joules (4.184 * 5000 * (80-20)), or 0.349 KWh. Now if you've only got 120W, that means it would take 2.91 hours (0.349 / 0.12) assuming you have zero heat loss.

However, unless you've got insulated containers, I'd doubt you'd ever get to 80degC.

Pretty much spot on. Tried it for the hell of it and got the top third of the water to 50c/
The rest stayed at 16c (workshop room temp). That was nearly 1 hour.

I am thinking 1000w min really as I don't want to wait too long for it and once one puts the part into the bucket the temp will go down quite a bit. So need it to be fast enough to recover from that.

Wondering if something like this would work?

Keeping in mind a 5L bucket is around 200-220mm tall?
Not sure if these are designed for water but should be okay as long as the top is kept above water line I believe.

With something like that, I'd be making sure they were well earthed, and powered via a good RCD.

Have you had a look at any of the youtube videos for ideas?
I've got these saved in my watch later list

It's been a while since I watched them, so can't remember exactly what they covered, but they must of contained something worthwhile that I never deleted them after watching them..

Thinking about it.
Cleaner, Dye and Sealer don't care if they are in a metal container?
Why not just use stainless cooking pots and put them on those cheap hot plates?

As variable knob too so could potentially not even need thermostat controller?

Obviously not put the acid/lye in these, they still need plastic containers.

that's probably the way i'd do it personally yeah

£11 for the hotplate, £8 for the 5L stainless pot. Total price is much better than Plastic tub plus heat element and controller...
