    zinc plating at home. now its all fun

    So I got sick of dropping stuff off to be plated & figured out its pretty easy to do it at home - not very expensive to make a setup either.

    You can buy a "kit" for about $2-300, or you can make your own for about $50. So of course I chose the latter.....

    Found this thread a few years ago and filed it away... http://www.gmh-torana.com.au/forums/...-zinc-plating/ he seemed to have made up a pretty simple setup, so i though i'd copy (& improve) his setup.

    In reality the most expensive part was the "food grade" buckets. Hardest part to get was the zinc, which i eventually found from a casting supplier. Had to convince him to sell me such a small quantity.

    Still playing with power supplies. Small parts easily plated with a 6v 500mA phone charger, but larger parts need more power - 12v 1000mA battery charger seems to work nicely.


    Can buy numerous passivating colors too - black might be worth exploring https://janekits.com.au/product-cate...s-passivating/


    Now have loads of bits to plate!

    I love the idea of this sort of thing, but I'm concerned about developing Covid-20 in the buckets over time. Are the chemicals safe to leave for (knowing me) several years in the buckets?
    Imagination is more important than knowledge.

        i have 4 buckets - one plain water (big deal swap all the time) the brightener (which just has some alloy cleaner in it), the acid bath (1l acid, 7l water) and the plating bath which is vinegar, epsom salts and sugar. cheap to change all the baths every few months when they show signs of contamination. good luck to anything growing in the acid bath!

        start digging out all those bolts this weekend to start plating up - got plenty of car projects

          cool stuff - might have to give this a go - I have one one of these as a power supply ive used for all sorts of stuff - slightly noisy, but moves pixies. - https://www.ebay.com.au/itm/Adjustab...frcectupt=true

          What did you pay for the casting zinc?

              zinc - about $8 a piece i thought. cut one piece into 4 and the other into 2, found this supplier off ebay - https://www.ebay.com.au/itm/Pure-Zin...MAAOSwNyFWgmjI

              needs to be very clean - wire brush, put in acid. then inspect. maybe wirebrush again. clean surface needed to plate too. sand/bead blasting would be good too

                For a power supply, old desktop computer PSUs are always easy to find. I had boxes of them at one point, never paid a cent for one. Regularly at the tip.
                There'll be a single green or brown wire, the only one of its colour. Attach that to ground (black) and the power supply is always on. Yellow is +12v, red is +5v.

                  Yeah, I've been using the same mixes for a couple of years.

                  The passivation mix can go a bit off, but the plating bath only needs a top up of brightener and a few minutes plating a dummy part to come good again.

                    Might be able to use sacrificial anodes for hot water systems etc as a source of zinc too?

                      They seem way more expensive than the ebay zinc guy - who was about the same as the boat anode price - but i assume might be a little more pure Vs chinaspec.

                        unless you can pull them off hot water systems, outboards, boats etc yourself that is!

                          Interesting that this comes up. I just got one of these for Nickel plating:
