DIY Zinc Plating

Postby Galactic Greyhound » Sun Jul 02, 2017 1:06 pm

Found this on YouTube.

I haven't tried it out myself but it looks feasable and could be a good use for an old battery that no longer starts the bike reliably.

It is important that the battery is connected the correct way round as described in the video or the plating won't work.

Also, the thickness of the plating depends on how long the item is connected up in the electrolyte solution:

These guys are really good and helpful, I had a go with some of their kit, and the results were encouraging for a novice.

Oh and loads of useful info on their site.

I like the tumbler for cleaning first. Good way to get the rust off bolts etc.

I've already had a go at electrolysis for removing rust. I bought an old Gamages (non auto) battery charger for the purpose and it works very well at around 1amp with dilute Sodium Carbonate as the electrolyte.

Electrolytic de-rusting tank powered with battery charger:-

Next project is to have a go at zinc plating and I have prepared a similar tank and ordered the zinc bars. I'll use the same charger for the job although the current rate may not be the same with a different electrolyte.

My power supply:-

If it works out, I plan to have a go at zinc plating the inside of my spare petrol tank by suspending the zinc bar inside the tank. I've seen Youtube vids of de-rusting tanks internally this way so no reason why the same method won't work for zinc plating.
Worth a try anyway.
If you don't make mistakes, then you aren't trying hard enough!

I'm assuming the setup he showed was just for demonstration purposes? :???:

Surely you would separate the bolts and nut from the part you were plating?

And you actually need the bare wire attached to the zine plate, not just the insulation.

And the part that is pressed against the glass bottle is not going to get any zinc plating on it. Far better to hang it away from any obstruction.

ETA: watching his other videos, he is just doing it for a bit of a laugh, a dry sense of humour. :grin: :lol:

That vibrating parts cleaner looked the business though. That would be so useful,for cleaning small fiddly items, and I do believe manufacturers use them for polishing complicated components such as carburettors etc, with the correct medium in of course.
