I did lightly brush the surface after 3 hours to try to speed up the cleaning.
Naturally it can't fix the loss of the surface coating but it's pretty impressive.

I've had good results and zinc on bike I built 10 years ago (ZZR) still looks good

I have hade some great results with the basic kit bought through Classic Plating.

Zinc plating kit that sound cool - I'll have to research it do you have a sellers link ?Sorry, just seen post - same company as already suggested - https://www.gaterosplating.co.uk/index.php?route=product/product&product_id=231
I also use an aquarium heaters and themometer to sort correct temp - to be honest, its only in the winter I bother with them as in the summer, its 'near enough'

Thanks for that Phil - as I keep tropical fish in my outside fishhouse/garage office annex the temperature will not be an issue.

Good advice on the tank heater, the plating solution needs to be 25-30 centigrade and putting a small bottle of hot water in the tank will help getting the temperature up as the tank heater can take a while to get it there. Bandaging the anodes is a help in stopping small particles of zinc getting into the solution and onto the item being plated. Filtering the solution when finished with it keeps it clean and two coffee filters in a funnel works well but takes a while to run though.
A power supply is essential although some seem to manage with one of those resistance wire arrangements.
Just as a bit of a trial I tried zinc plating a brass bezel. I didn't prep it very well just wanted to see if it would plate. Came up quite well and now I regret the prep wasn't better.

I bought one on fleabay. Ash is the best one who will know which is best although he probably made his own.

As I understand the process the ampage is the critical factor that drives the plating process, hence the 100 mAmps per square inch. The power box I borrowed allowed me to set ampage and the box adjusted the voltage, I often had nearly 0.5V showing so a measurement of the amp draw is essential.
I will take that onboard if I decide to try it - my BiL Dave has a kit of some sort but no solution yet.

It would have to be simple for those of us with minimal elecrickery skills or knowledge. 🙂
The simple filament wire controller included with the kit is very hit and miss.

Is it possible to rig up some kind of cheap and cheerful digital current controller if using a 12v battery charger as the power source?

You can use an LM338 reguator in constant current limit mode...

I think you are wrong there Steve ..Ian is an 'ull lad ;D and keen to learn... he's already made and used a version of the Ashimoto curing oven :) ;D Its only a three legged device and a resistor & capacitor after all. Ian you coud probably used the resistance wire you got with your basic kit as a variable resistor (R1 in circuit) and I can get you an LM338 no probs for free. Needs a decent heatsink though.

Ash
The circuit appears to be a constant current control circuit irrespective of input voltage.
If I want to make this a variable current controller is it simply a matter of installing a potentiometer in the output side of the circuit as a variable resistor?
Cheers Ian

Yea just make R1 variable .. you need constant current for plating preferably.. .sorry for thread hijack from me too.

I took one look at Ash's setup and immediately thought, send my stuff to the platers!
:D :D
I don't tend to use it much now just for small items ...I send 99.5% to Allenchrome now.
However, a lot of people like to have a go themselves ...like Oggie400F ...I loaned my kit & chemicals to another bloke in Hull a few years back and he zinc plated everything on his CB750K2 with it and the bike was featured in Classic Bike magazine bikes of the year.

I took one look at Ash's setup and immediately thought, send my stuff to the platers!Once you set the kit up (as it comes from from Gateros for example) - and if you have the space to keep it set up, its dead easy to get decent results. Ash's set up looks scary if you haven't used the kit (and don't understand the art of electrickery).
:D :D
I refurb things as I strip them off the bike - say top and bottom yokes (paint, re-zinc, replace bolts, etc) so that when I put everything back together, everything is done - so for me, it works a treat.

Fed up of this ;D ;D ;D The actual constant current circuit bit is mega simplz ..The rig pictured was also a speed controller for the stirrer etc which isn't essential.
I will put together a 'how to build' in Anoraks Corner without any soldering involved....just to prove my point.
BTW I designed the electronics for Caswell Europes semi-pro multi tank system and I evaluated this supply below attached from Gateros. Gateros kits are normally great but this power unit was absolute sh8te build quality inside and I would be wary of its electrical safety. So my advice is DON'T buy.
