Joe cell

[Nenad Davinic]

Hello,I am from Serbia,litle country in Europe.I am very interested to make a Joe\’s cell but it is quite impossible to obtain a 316 L quality tubes.My qestion is,is it possible to make the cell from copper or copper plated with chrom or nikel if it is possible Should I use Acid or alkaline solution.

Hi Nenad,

You cannot use copper in an underwater application where electricity is involved. it will completely corrode in a very fast way. I\’ve tried it. A long time ago when I was first developing the moe-joe cell.

plating with chrome or nickel will also not help.
you really need good solid magnetic-free 316 stainless steel. ideally, 316L (L means Low carbon – it makes it less magnetic)

As far as acid or alkali – i say, neither.
I definitely wouldn\’t add anything.
i like a pH neutral or a little alkaline, if anything.

Alex Schiffer has a section on the acid-alkali question in Experimenter\’s Guide to the Joe Cell.

Thanks Moshe. Can you tell me where in Europe i can fine 316L?

Hi Nenad,

Here is what i found for you:

Viktor from the Joe cell group said: We call it \’ 1.4404 \’ quality steel, or \’acid proof stainless steel\’

Yhank you Moshe.

You\’re welcome Nenad.
Here is some more information and ideas of where you can get some 316L stainless steel for the joe cell:

quote :

\”Hi Moshe,

Hang around a dairy, brewery or a yeast factory. Ask for off cuts. Check the tube, it should have the specification printed somehow on the tube. The experts may be able to tell you the grade by how it looks, handles and sparks. Tube is thin wall material, like 1.0 to 2.0 mm depending on diameter. Pipe is heavier wall thickness; that you may get at boilermakers, chemical plant manufactureres, shipbuilders.\” Tony from the Joe cell community

čovik, ima ih po hr koliko hoćeš… čudno da nema kod vas, potraži bolje. Meni je bilo nezgodno naći 2,3,4,5 incha 316, pa sam uzeo 304, bitno da je nemagnetično… 316 je otporniji ali i 304 je inox, za prehrambenu industriju, isto ok. samo nisu sve polirane pa se sad jebem sa tim….. brusi i šuti !!!

počeo sam sastavljati, moraš naći i tokara da ti napravi podnožje i zavariti inox isto…
