How I Packed my Column

[Urrazeb]

Hi this is how I packed my FSD neutraliser.

500mm 4in column

I got lucky and had access to a heap of pure copper mesh, you don't need full copper packing but a bit more copper won't hurt hey? :handgestures-thumbupleft: I like the idea of having confidence in a full copper packed section though.

The mesh I had access to was 100mm wide, it was a woven stocking, quite common and seems to be the standard size/weave available.


It came in a roll and I stretched it while rolling a tight "scroll" 4in in diameter.

Roll until its a good fit, you need to ensure it is tight at the start of the scroll or you can create a void or a weak spot as far as packing is concerned. I rolled this until it has a little resistance when being pushed into the column

I then trimmed a section of stocking about 300mm, flared it out into a cylinder and placed the scroll inside

Then I twisted each end of the wrapping like a lolly and pushed it into the tight centre of the scroll to create a slight dip

I then checked for fit

And that's how I did it, hope I can help some one as I remember not too long ago this sorta info helped me a lot. Times have changed and so have the products available so hopefully this fits the bill :handgestures-thumbupleft:


Couple of things to mention;
Clean copper is not always clean. This is what came out during the vinegar run AFTER a strong citric boil

After a few runs your copper will tarnish, this shows you that it is doing it's job it is called 'Patina' and shows that it is picking up the sulphides in this application.

Thanks for reading and I hope I can be of some help to someone. :handgestures-thumbupleft:

Thanks, good pictures for me. I was going to soak my copper in a hot sodium bicarbonate solution to get the oil of then boil it again in citric acid solution.

Cool glad to help.

Be sure to boil in stainless steel only, the copper will tend to 'draw' from a reactive pot and will go almost black in places
